If nothing else, the IBM i platform has exhibited extraordinary sturdiness. One might even shriek legendary longevity, if you want to recall its heritage the entire manner back to the system/three minicomputer from 1969. here is the actual birth aspect in the AS/400 household tree and here is when massive Blue, for terribly sound criminal and technical and marketing reasons, determined to fork its products to wield the absorbing wants of colossal companies (with the gadget/360 mainframe and its follow-ons) and wee and medium agencies (starting with the system/3 and relocating on throughout the device/34, system/32, system/38, and gadget/36 in the Nineteen Seventies and early Nineteen Eighties and passing in the course of the AS/400, AS/400e, iSeries, gadget i, after which IBM i on punch techniques systems.
It has been a long race indeed, and many shoppers who tolerate invested within the platform begun route lower back then and there with the early versions of RPG and moved their applications forward and adjusted them as their organizations advanced and the depth and breadth of company computing modified, affecting on up through RPG II, RPG III, RPG IV, ILE RPG, and now RPG free form. Being on this platform for even three many years makes you a relative newcomer.
there is a longer race ahead, on account that they consider that the companies that are nonetheless operating IBM i techniques are the legal diehards, the ones who tolerate no object of leaving the platform and that, at the least in response to the survey records we've been privy too, are aspiring to proceed investing in, and even expand their investments in, the IBM i platform.
to this point, they don't appear to be in a recession and heaven willing there should not one, so the priorities that IBM i retail outlets tolerate are not the ones that they had a decade in the past utter over the height of the excellent Recession. lower back then, as turned into the case in almost utter IT companies, IBM i shops tolerate been hunkering down and were attempting to slit fees in utter techniques feasible, together with deferring equipment upgrades and migrations in addition to reducing lower back on other projects. most efficient 29 percent of the 750 IBM i stores that participated in the 2019 IBM i marketplace Survey, which HelpSystems did returned in October 2018, tolerate been worried about decreasing IT spending. here is a remarkably low stage, and that i feel is indicative of how highly efficient the economic system is – excepting one of the most fits and begins they noticed at the conclusion of 2018 and perquisite here in early 2019 that do us nervous and could birth putting constrain on issues. listed here are the legal considerations as culled from the survey:
dealing with the augment in records and in finding out the analytics to gnaw on that records ranked a bit bit larger on the 2019 IBM i market Survey than did reducing fees, and that i believe over the lengthy haul these concerns will become more crucial than modernizing functions and dealing with the IBM i expertise shortages that are a perennial be troubled. both of those issues are being solved as unique programmers and unique tools to do unique interfaces to database applications tolerate become greater common and as applied sciences corresponding to free figure RPG, which looks extra like Java, Python, and personal home page, are being more commonly deployed and, importantly, will furthermore be picked up extra quickly by programmers skilled with these different languages.
Given the nature of the consumer base, it appears not going to me that safety and exorbitant availability will now not proceed to be basic considerations, despite the fact that the IBM i platform is among the most relaxed structures in the world (and not just since it is vague, however because it is exceptionally tangled to hack) and it has a achieve of exorbitant availability and catastrophe recovery equipment (from IBM, Syncsort, Maxava, and HelpSystems) attainable for people that are looking to double up their programs and tender protection to their functions and records. The bar is regularly higher than elementary backup and recuperation for many IBM i retail outlets within the banking, insurance, manufacturing, and distribution industries that dominate the platform. These groups can’t tolerate security breaches, and they can’t tolerate downtime.
there is a extraordinary volume of steadiness within the IBM i customer basis that they suppose, at this aspect, is reflective within the stability of the IBM i platform and roomy Blue’s own perception that it needs a felicitous IBM i platform to tolerate an overall in shape punch programs business. utter of us recognize that the energy techniques hardware enterprise has simply became in 5 quarters of profits growth – whatever they discussed currently in setting up their personal salary model for the vigour methods company – but what they did not be cognizant of, and what do confident to know, is that within the second and third quarters of 2018, the IBM i portion of the company grew tremendously faster than the proper energy systems business, and the only intent that this didn't occur within the ultimate quarter of 2018 is that income of IBM i machinery in this descend 2017 became quite stout and represented a extremely complicated evaluate. The point is, the IBM i company has been raising the power methods kind general. (These pointers about the IBM i enterprise further compliments of Steve Sibley, vice president and providing manager of Cognitive methods at IBM.)
IBM’s own fiscal balance of the energy platform – which has been bolstered through a stream into Linux clusters for analytics and exorbitant efficiency computing simulation and modeling as well as via the adoption of the HANA in-memory database by means of SAP shoppers on massive iron machines including Power8 and now Power9 methods – helps IBM i consumers consider greater confident in investing within the latest IBM i platform. The recent proof from several diverse surveys, not simply the one accomplished by means of HelpSystems every year, suggests that groups are through and massive either continuing to do investments within the platform or even in some cases are planning to raise their spending on the IBM i platform in 2019.
As which you can see, the pattern of funding plans for the IBM i platform, as proven within the chart above, has not modified very a marvelous deal at utter in the past four years. it's a remarkably solid pattern with but a bit wiggling here and there that might furthermore now not even be statistically giant. simply below 1 / 4 of IBM i stores tolerate stated during the past four years that they procedure to raise their funding in the platform in every year, and just beneath half shriek that they are conserving regular. This doesn't imply that the equal agencies, 12 months after year, are investing extra and other businesses are staying pat, year after yr. it's much more likely that each handful of years – greater like four or five – consumers better their techniques and extend their capacity, and that they then sit tight. The await yourself is that the split isn’t showing a long route fewer corporations investing and far more sitting tight. That more than a tenth of the retail outlets don’t recognize what their procedure is as each prior 12 months comes to a nearby is slightly worrying, however it is wholehearted and indicates that a marvelous portion of shops tolerate other priorities apart from hardware and operating system upgrades. we've said this before and they are able to shriek it again: They feel that the people who reply to surveys and browse weekly publications concentrated on the IBM i platform are essentially the most lively retail outlets – those extra likely to dwell especially latest on hardware and utility. So the tempo of adoption for unique applied sciences, and the rate of funding, should quiet be higher than within the precise base, lots of which does not trade tons at all.
So if they had to adjust this information to recall on the complete base, there may be far fewer websites that are investing extra funds, route more organizations which are sitting tight, and maybe fewer websites that are thinking of affecting off the IBM i platform. I feel the distribution of records is probably something like 10 p.c of shops tolerate no theory what they are doing investment ingenious with IBM this 12 months, 5 p.c are considering relocating some or utter of their applications to a further platform, probably 10 % are investing more this yr, and the ultimate seventy five % are sitting tight. here is just a guess, of course. as far as they will inform, the cost of attrition – what number of websites they truly lose each and every yr – just a tad over 1 percent. So the cost of stream of functions off the platform, or incidences of unplugging IBM i databases and purposes, may furthermore not be anyplace nearby as tall in the yardstick basis because the information above suggests. what is alarming, in utter probability, is that the fee of affecting some or utter applications off the platform is balanced in opposition t people who shriek they will raise investments. most likely these are hopeful survey takers, and those that consider it's effortless to circulate learn it isn't and people who mediate they'll locate the money to do investments will not.
What they carry out comprehend is that if the expense of application attrition was anyplace near as tall as these surveys suggest, then the IBM i company would not be turning out to be, however shrinking. And they realize it isn't shrinking, so they consider there's a disconnect between planning and reality, both on the upside and the draw back.
in case you drill down into the facts for the 2019 IBM i industry Survey, there were 13 % of retailers that observed they would be relocating some applications to a unique platform, and an additional 9 % that talked about they had been going to circulation utter of their purposes off IBM i. (This quantity is in keeping with the simultaneous ALL400s survey accomplished by John Rockwell.)
Anyway, marvelous luck with that.
Porting purposes from one platform to a further, of buying a unique suite on that unique platform, is an enormously elaborate assignment. It is not like trying to trade a tire whereas using down the street, as is a yardstick metaphor, however quite like attempting to recall the tire off one car relocating down the motorway and installing it on another car using beside it within the adjacent lane devoid of crashing either automobile or smashing into any individual else on the road. Optimism abounds, but when shove comes to shove, very few groups are trying the sort of maneuver, and once they do, it's continually as a result of there's a company mandate, extra instances than not led to by route of a merger or acquisition, that pits another platform towards IBM i running on vigour systems. organizations that shriek they are making this benign of walkover off IBM i are sanguine for their personal own reasons, most likely, however they are not always practical about how long it may take, what disruption it'll charge, and what surest benefit, if any, will be realized.
if you carry out the maths on the chart above, eight-tenths of the basis has no design how long a movement will take, one more 1.7 percent thinks it'll recall more than five years, and 3 % shriek it'll recall between two years and five years. most efficient three.four p.c of the total basis shriek they could carry out it in below two years. They consider utter of these numbers are confident, and the businesses who could comfortably depart OS/400 and IBM i already did a long time ago and people that are remain tolerate a harder time, now not a less complicated time, moving. If this tolerate been no longer actual, the IBM i basis could be a hell of an dreadful lot smaller than the a hundred and twenty,000 purchasers they believe are out there, in accordance with what great Blue has told us in the past. here's the discrepancy between concern or power or culture and the reality of making an attempt to stream a company off one platform and onto one more. These strikes are utter the time an dreadful lot tougher than they Look on the entrance end, and they suspect many of the advantages furthermore don’t materialize for people that carry out jump structures.
on the yardstick attrition cost advised with the aid of this survey information – 9 % stream off the platform in somewhere between three hundred and sixty five days and more than 5 years, with most agencies no longer being in a position to contemplate more than 5 years into the future this is a tidy trick – the residence in basis would reduce dramatically. it is challenging to shriek how far because of the wide achieve of timeframes within the survey. If it became 9 % of the basis within two years – convoke it 4.5 % of the bottom per yr – then inside a decade the middling basis would slit back from one hundred twenty,000 IBM i sites international perquisite down to about 72,000. this could melodramatic indeed. but at a 1 percent attrition cost per yr, the basis is quiet at 107,500 wonderful clients (no longer sites and not residence in machines, both of which are bigger) by using 2029. They mediate there is each possibility that the attrition expense will in reality gradual and drop below 1 % as IBM demonstrates commitment to the vigour methods platform and its IBM i operating equipment. There are at utter times some unique customers being added in unique markets, to be sure, however the bleed cost (besides the fact that it is small) continues to be likely an order of magnitude larger than the feed fee.
when they carry out consider about making the circulation, IBM i retail outlets be cognizant of exactly the residence they requisite to go, and this retort has been step by step changing over the years: Linux as a substitute for IBM i is on the upward shove and home windows Server as an alternative is on the wane. in the newest survey, fifty two percent of the organizations that stated they were affecting utter or some of their applications to a different platform pointed out they tolerate been settling on home windows Server, whereas 34 percent selected Linux. This displays the relative popularity of windows Server and Linux in the datacenters of the world at colossal, and can be tipped simply a bit greater closely towards Linux compared to the relaxation of the area. apparently, 10 p.c of those polled who spoke of they tolerate been affecting tolerate been taking a Look at AIX systems, and an additional four p.c tolerate been going upscale to gadget z mainframes – as unlikely as this may additionally look. platforms are inclined to roll downhill; they carry out not always beard gravity like that.
The aspect about such surveys is that they parade intent, no longer action. They commonly intend to carry out a lot more than they in reality can accomplish, and affecting platforms after spending a long time of structure up skills is not continually a very smart circulate unless the platform is in actual situation – like the Itanium programs from Hewlett Packard commercial enterprise working OpenVMS or HP-UX or the HP 3000s operating MPE or the Sparc programs from Oracle running Solaris. These tolerate been once terrific platforms with huge residence in bases and tremendous income streams, but now, IBM is the final of those Unix and proprietary systems with its energy methods line. And it's by route of a ways the greatest and for certain the just one displaying any growth.

What’s Up within the IBM i industry?
IBM i market Survey Fills in the Blanks
In September 2018, IBM announced a brand unique product, IBM Db2 AI for z/OS. This synthetic intelligence engine displays data access patterns from executing SQL statements, makes utilize of desktop researching algorithms to choose most excellent patterns and passes this tips to the Db2 query optimizer to be used through subsequent statements.
desktop getting to know on the IBM z Platform
In might furthermore of 2018, IBM announced edition 1.2 of its computing device gaining information of for z/OS (MLz) product. this is a hybrid zServer and cloud utility suite that ingests performance information, analyzes and builds fashions that symbolize the health status of numerous indications, displays them over time and provides real-time scoring capabilities.
a few elements of this product offering are aimed toward supporting a community of model developers and executives. for example:
It helps distinctive programming languages such as Python, Scala and R. This allows records modelers and scientists to do utilize of a language with which they're accepted;
A graphical consumer interface called the visual mannequin Builder courses model developers with out requiring highly-technical programming skills;
It comprises dissimilar dashboards for monitoring mannequin effects and scoring services, in addition to controlling the system configuration.
This computing device discovering suite turned into originally geared toward zServer-based analytics functions. one of the vital first obvious decisions become zSystem performance monitoring and tuning. gadget administration Facility (SMF) records that are immediately generated by using the operating gadget supply the uncooked statistics for device aid consumption corresponding to imperative processor usage, I/O processing, reminiscence paging and the like. IBM MLz can assemble and store these records over time, and construct and discipline fashions of system habits, rating these behaviors, establish patterns not comfortably foreseen by route of humans, further key efficiency indicators (KPIs) and then feed the model results lower back into the equipment to tolerate an upshot on equipment configuration changes that may better performance.
The next step changed into to residence in constrain this suite to research Db2 efficiency records. One solution, referred to as the IBM Db2 IT Operational Analytics (Db2 ITOA) retort template, applies the laptop studying know-how to Db2 operational information to profit an knowing of Db2 subsystem fitness. it might dynamically construct baselines for key performance warning signs, provide a dashboard of those KPIs and provides operational workforce actual-time insight into Db2 operations.
while regular Db2 subsystem performance is a vital component in proper application fitness and performance, IBM estimates that the DBA guide workforce spends 25% or greater of its time, " ... fighting access direction complications which trigger efficiency degradation and service tolerate an upshot on.". (See Reference 1).
AI involves Db2
trust the plight of modern DBAs in a Db2 environment. In today's IT world they tolerate to aid one or greater great statistics purposes, cloud utility and database features, utility installation and configuration, Db2 subsystem and utility performance tuning, database definition and administration, catastrophe healing planning, and greater. query tuning has been in existence since the origins of the database, and DBAs are continually tasked with this as smartly.
The heart of question course evaluation in Db2 is the Optimizer. It accepts SQL statements from functions, verifies authority to access the facts, reports the places of the objects to be accessed and develops a listing of candidate data entry paths. These access paths can encompass indexes, table scans, numerous desk associate methods and others. within the data warehouse and massive information environments there are continually extra selections available. One of those is the existence of summary tables (from time to time called materialized query tables) that accommodate pre-summarized or aggregated facts, as a result enabling Db2 to evade re-aggregation processing. yet another option is the starjoin entry route, usual in the facts warehouse, the residence the order of desk joins is changed for performance explanations.
The Optimizer then studies the candidate access paths and chooses the access course, "with the lowest can charge." can saturate in this context potential a weighted summation of useful resource utilization including CPU, I/O, recollection and other materials. finally, the Optimizer takes the bottom saturate access course, stores it in reminiscence (and, optionally, in the Db2 directory) and starts entry direction execution.
massive information and records warehouse operations now encompass utility suites that permit the enterprise analyst to do utilize of a graphical interface to build and maneuver a miniature information mannequin of the information they want to analyze. The packages then generate SQL statements based on the users’ requests.
The issue for the DBA
with the object to carry out decent analytics on your dissimilar information stores you requisite a marvelous understanding of the records necessities, an understanding of the analytical services and algorithms available and a high-efficiency facts infrastructure. lamentably, the number and location of information sources is expanding (both in dimension and in geography), data sizes are becoming, and functions proceed to proliferate in number and complexity. How should quiet IT managers back this ambiance, notably with the most skilled and develope corpse of workers nearing retirement?
be cognizant furthermore that a huge Part of reducing the entire saturate of ownership of those systems is to obtain Db2 purposes to race faster and greater efficaciously. This continually interprets into using fewer CPU cycles, doing fewer I/Os and transporting much less data throughout the community. given that it's often intricate to even identify which applications could improvement from performance tuning, one routine is to automate the detection and correction of tuning concerns. here is where machine researching and ersatz intelligence will furthermore be used to notable effect.
Db2 12 for z/OS and ersatz Intelligence
Db2 edition 12 on z/OS makes utilize of the desktop researching facilities outlined above to acquire and retain SQL question text and entry direction particulars, as well as precise efficiency-connected historical assistance akin to CPU time used, elapsed times and influence set sizes. This offering, described as Db2 AI for z/OS, analyzes and outlets the facts in desktop studying fashions, with the mannequin evaluation results then being scored and made attainable to the Db2 Optimizer. The next time a scored SQL commentary is encountered, the Optimizer can then utilize the model scoring information as enter to its access route option algorithm.
The result may quiet be a reduction in CPU consumption as the Optimizer makes utilize of mannequin scoring input to opt for more suitable entry paths. This then lowers CPU charges and speeds application response times. a major capabilities is that the usage of AI software does not require the DBA to tolerate information science talents or profound insights into question tuning methodologies. The Optimizer now chooses the top of the line entry paths based now not best on SQL query syntax and records distribution facts however on modelled and scored historical performance.
This can be notably crucial in case you reclaim information in distinctive places. for example, many analytical queries against great information require concurrent access to certain information warehouse tables. These tables are generally known as dimension tables, and that they comprehend the information aspects always used to control subsetting and aggregation. as an instance, in a retail environment agree with a desk referred to as StoreLocation that enumerates every shop and its region code. Queries against retain income statistics may are looking to compund or summarize earnings by means of region; hence, the StoreLocation table will be used via some massive records queries. during this environment it's regular to recall the dimension tables and replica them regularly to the massive records application. in the IBM world this region is the IBM Db2 Analytics Accelerator (IDAA).
Now suppose about SQL queries from each operational applications, records warehouse users and great statistics business analysts. From Db2's standpoint, utter these queries are equal, and are forwarded to the Optimizer. despite the fact, within the case of operational queries and warehouse queries they should obviously be directed to entry the StoreLocation desk in the warehouse. on the other hand, the query from the enterprise analyst in opposition t massive facts tables should doubtless access the copy of the desk there. This consequences in a proliferations of skills access paths, and greater labor for the Optimizer. fortuitously, Db2 AI for z/OS can deliver the Optimizer the tips it must do smart access route decisions.
how it Works
The sequence of activities in Db2 AI for z/OS (See Reference 2) is often here:
all the route through a bind, rebind, residence together or interpret operation, an SQL remark is handed to the Optimizer;
The Optimizer chooses the information entry direction; because the alternative is made, Db2 AI captures the SQL syntax, access direction preference and question efficiency records (CPU used, and so on.) and passes it to a "discovering project";
The discovering assignment, which can furthermore be finished on a zIIP processor (a non-established-goal CPU core that does not aspect into application licensing prices), interfaces with the desktop discovering utility (MLz mannequin services) to store this advice in a mannequin;
because the quantity of records in each and every model grows, the MLz Scoring provider (which furthermore can be finished on a zIIP processor) analyzes the mannequin statistics and scores the habits;
all through the subsequent bind, rebind, residence together or explain, the Optimizer now has entry to the scoring for SQL fashions, and makes preempt changes to entry path selections.
There are additionally a lot of user interfaces that provide the administrator visibility to the reputation of the gathered SQL remark efficiency information and mannequin scoring.
IBM's desktop researching for zOS (MLz) providing is getting used to high-quality upshot in Db2 edition 12 to augment the performance of analytical queries as well as operational queries and their associated applications. This requires administration attention, as you requisite to investigate that your company is prepared to consume these ML and AI conclusions. How will you measure the fees and merits of the usage of computing device gaining information of? Which IT back personnel ought to be tasked to reviewing the outcome of model scoring, and maybe approving (or overriding) the outcomes? How will you evaluate and warrant the assumptions that the software makes about access route decisions?
In other words, how well did you know your information, its distribution, its integrity and your current and proposed entry paths? this may verify the residence the DBAs disburse their time in aiding analytics and operational utility efficiency.

Progress DataDirect Offers Complementary back for IBM CICS TS v4.1
End-to-end solution extends CICS events capability to comprehend mainframe database business events, tangled event processing
Note: ESJ’s editors carefully choose vendor-issued press releases about unique or upgraded products and services. They tolerate edited and/or condensed this release to highlight key features but do no claims as to the accuracy of the vendor's statements.
Progress DataDirect, the data infrastructure division of Progress Software Corporation announced it back for event processing capabilities available in the IBM Customer Information Control System (CICS) Transaction Server (TS) version 4.1, allowing organizations that trust on System z mainframes to more fully exploit the benefits of event-driven architectures.
IBM mainframes are the dominant platform for fiscal services and serve as a vital infrastructure component for many industries, including manufacturing, telecommunications, and situation and local government institutions. With cross-industry appeal, the top 50 worldwide banks and 22 of the top U.S. retailers race IBM System z. IBM CICS is one of the most widely used mainframe application hosting environments in the world, and as such is an environment wealthy in business meaningful events.
With the launch of CICS TS v4.1, IBM has included unique event technologies to enable CICS to be configured to feed business event processing engines and business dashboards without the requisite for application change. CICS event processing is focused on application events of significance to the business rather than systems management or IT events. The primary intent of this office is to allow existing applications to be non-invasively instrumented for events, so that events can be produced by the applications without the requisite for any code changes. The faculty to generate business events without changing application programs both reduces cost and complexity and delivers compliant elastic business solutions.
Progress Software, through its Progress Apama event processing and Progress DataDirect Shadow products, provides a comprehensive, end-to-end solution to complement and extend CICS TS v4.1 events. Apama offers a flexible, tangled event processing (CEP) platform for structure event-driven applications.
Apama event processing monitors rapidly affecting event streams, detects and analyzes well-known patterns, and acts in less than a millisecond. With Apama event processing, CICS business events now can be correlated and analyzed in real-time, providing unique levels of decision-making that dramatically improves operational responsiveness.
The DataDirect Shadow platform is a single, foundation architecture that supports utter industry-standard requirements for integrating mainframe data, business logic, and screens with SOAs and/or data-centric applications. Within the DataDirect Shadow product is a complete facility for the real-time capture and publication of events that occur within mainframe databases including DB2 for z/OS, VSAM, IMS/DB, CA-IDMS, or Adabas.
The DataDirect Shadow platform complements the CICS TS v4.1 out-of-the-box event capabilities with the faculty to persist and deliver CICS events over MQ and/or HTTP/HTTPS; and to augment CICS-generated events with database events that collectively provide wealthy and contextual information that can be further analyzed by Apama event processing. The DataDirect Shadow product not only captures and persists utter events, it provides capabilities to filter, aggregate and enrich events to augment the context and business significance of the technical database change.
The DataDirect Shadow platform’s technology for reducing mainframe integration costs enables utter processing related to events to be diverted from the mainframe universal purpose processor (GPP) to the System z integrated information processor (zIIP) specialty engine. This capability was developed in nearby partnership with the IBM System z group and therefore does not judgement IBM or any other third-party code to become zIIP-enabled.
Additional back for CICS TS v4.1
CICS TS v4.1 introduces a wide achieve of technical and operational capabilities. In addition to the back for business events, the DataDirect Shadow platform provides back for key features within CICS TS v4.1 that simplify development, systems management and installation between the two products. Additional back includes:
Integration with CICS Explorer: The CICS Explorer is an Eclipse-based systems management tool framework for CICS. Shadow Studio is an Eclipse-based integration administration and systems management tool for utter DataDirect Shadow mainframe resources. In back of the CICS Explorer, the Shadow Studio can now be accessed from within CICS Explorer.
Utilization of Bundles: A bundle is a collection of CICS resources, artifacts, references, and a manifest that users can deploy into a CICS region to represent an application. The DataDirect Shadow platform utilizes CICS bundle back to simplify customer installation and configuration of the DataDirect Shadow software into CICS environments.
“The majority of Fortune 500 and major government entities utilize CICS running on z/OS for their core business functions. The addition of event capture back in CICS TS v4.1 will undoubtedly augment the interest in events and CEP for mainframe customers,” said Gregg Willhoit, chief architect at Progress DataDirect. “By capturing mainframe-based events in real-time and offloading the event-capture processing to the zIIP specialty engine, the DataDirect Shadow product can react to a rapidly changing business environment while helping lower mainframe TCO and providing a more streamlined integration within the context of SOA.”

In September 2018, IBM announced a unique product, IBM Db2 AI for z/OS. This ersatz intelligence engine monitors data access patterns from executing SQL statements, uses machine learning algorithms to rule on optimal patterns and passes this information to the Db2 query optimizer for utilize by subsequent statements.
Machine Learning on the IBM z Platform
In May of 2018, IBM announced version 1.2 of its Machine Learning for z/OS (MLz) product. This is a hybrid zServer and cloud software suite that ingests performance data, analyzes and builds models that represent the health status of various indicators, monitors them over time and provides real-time scoring capabilities.
Several features of this product offering are aimed at supporting a community of model developers and managers. For example:
It supports multiple programming languages such as Python, Scala and R. This allows data modelers and scientists to utilize a language with which they are familiar;
A graphical user interface called the Visual Model Builder guides model developers without requiring highly-technical programming skills;
It includes multiple dashboards for monitoring model results and scoring services, as well as controlling the system configuration.
This machine learning suite was initially aimed at zServer-based analytics applications. One of the first obvious choices was zSystem performance monitoring and tuning. System Management Facility (SMF) records that are automatically generated by the operating system provide the raw data for system resource consumption such as central processor usage, I/O processing, recollection paging and the like. IBM MLz can collect and store these data over time, and build and train models of system behavior, score those behaviors, identify patterns not readily foreseen by humans, develop key performance indicators (KPIs) and then feed the model results back into the system to paw system configuration changes that can better performance.
The next step was to implement this suite to anatomize Db2 performance data. One solution, called the IBM Db2 IT Operational Analytics (Db2 ITOA) solution template, applies the machine learning technology to Db2 operational data to gain an understanding of Db2 subsystem health. It can dynamically build baselines for key performance indicators, provide a dashboard of these KPIs and give operational staff real-time insight into Db2 operations.
While universal Db2 subsystem performance is an well-known factor in overall application health and performance, IBM estimates that the DBA back staff spends 25% or more of its time, " ... fighting access path problems which judgement performance degradation and service impact.". (See Reference 1).
AI Comes to Db2
Consider the plight of modern DBAs in a Db2 environment. In today's IT world they must back one or more roomy data applications, cloud application and database services, software installation and configuration, Db2 subsystem and application performance tuning, database definition and management, catastrophe recovery planning, and more. Query tuning has been in existence since the origins of the database, and DBAs are usually tasked with this as well.
The heart of query path analysis in Db2 is the Optimizer. It accepts SQL statements from applications, verifies authority to access the data, reviews the locations of the objects to be accessed and develops a list of candidate data access paths. These access paths can comprehend indexes, table scans, various table associate methods and others. In the data warehouse and roomy data environments there are usually additional choices available. One of these is the existence of summary tables (sometimes called materialized query tables) that accommodate pre-summarized or aggregated data, thus allowing Db2 to avoid re-aggregation processing. Another option is the starjoin access path, common in the data warehouse, where the order of table joins is changed for performance reasons.
The Optimizer then reviews the candidate access paths and chooses the access path, "with the lowest cost." Cost in this context means a weighted summation of resource usage including CPU, I/O, recollection and other resources. Finally, the Optimizer takes the lowest cost access path, stores it in recollection (and, optionally, in the Db2 Directory) and begins access path execution.
Big data and data warehouse operations now comprehend software suites that allow the business analyst to utilize a graphical interface to build and maneuver a miniature data model of the data they wish to analyze. The packages then generate SQL statements based on the users’ requests.
The Problem for the DBA
In order to carry out marvelous analytics on your multiple data stores you requisite a marvelous understanding of the data requirements, an understanding of the analytical functions and algorithms available and a high-performance data infrastructure. Regrettably, the number and location of data sources is expanding (both in size and in geography), data sizes are growing, and applications continue to proliferate in number and complexity. How should IT managers back this environment, especially with the most experienced and develope staff nearing retirement?
Understand furthermore that a great Part of reducing the total cost of ownership of these systems is to obtain Db2 applications to race faster and more efficiently. This usually translates into using fewer CPU cycles, doing fewer I/Os and transporting less data across the network. Since it is often difficult to even identify which applications could benefit from performance tuning, one approach is to automate the detection and correction of tuning issues. This is where machine learning and ersatz intelligence can be used to remarkable effect.
Db2 12 for z/OS and ersatz Intelligence
Db2 version 12 on z/OS uses the machine learning facilities mentioned above to accumulate and store SQL query text and access path details, as well as actual performance-related historical information such as CPU time used, elapsed times and result set sizes. This offering, described as Db2 AI for z/OS, analyzes and stores the data in machine learning models, with the model analysis results then being scored and made available to the Db2 Optimizer. The next time a scored SQL statement is encountered, the Optimizer can then utilize the model scoring data as input to its access path preference algorithm.
The result should be a reduction in CPU consumption as the Optimizer uses model scoring input to choose better access paths. This then lowers CPU costs and speeds application response times. A significant handicap is that using AI software does not require the DBA to tolerate data science skills or profound insights into query tuning methodologies. The Optimizer now chooses the best access paths based not only on SQL query syntax and data distribution statistics but on modelled and scored historical performance.
This can be particularly well-known if you store data in multiple places. For example, many analytical queries against roomy data require concurrent access to certain data warehouse tables. These tables are commonly called dimension tables, and they accommodate the data elements usually used to control subsetting and aggregation. For example, in a retail environment consider a table called StoreLocation that enumerates every store and its location code. Queries against store sales data may wish to aggregate or summarize sales by Location; hence, the StoreLocation table will be used by some roomy data queries. In this environment it is common to recall the dimension tables and copy them regularly to the roomy data application. In the IBM world this location is the IBM Db2 Analytics Accelerator (IDAA).
Now mediate about SQL queries from both operational applications, data warehouse users and roomy data business analysts. From Db2's perspective, utter these queries are equal, and are forwarded to the Optimizer. However, in the case of operational queries and warehouse queries they should most likely be directed to access the StoreLocation table in the warehouse. On the other hand, the query from the business analyst against roomy data tables should probably access the copy of the table there. This results in a proliferations of potential access paths, and more labor for the Optimizer. Luckily, Db2 AI for z/OS can provide the Optimizer the information it needs to do smart access path selections.
How It Works
The sequence of events in Db2 AI for z/OS (See Reference 2) is generally the following:
During a bind, rebind, prepare or interpret operation, an SQL statement is passed to the Optimizer;
The Optimizer chooses the data access path; as the preference is made, Db2 AI captures the SQL syntax, access path preference and query performance statistics (CPU used, etc.) and passes it to a "learning task";
The learning task, which can be executed on a zIIP processor (a non-general-purpose CPU core that does not factor into software licensing charges), interfaces with the machine learning software (MLz Model Services) to store this information in a model;
As the amount of data in each model grows, the MLz Scoring Service (which furthermore can be executed on a zIIP processor) analyzes the model data and scores the behavior;
During the next bind, rebind, prepare or explain, the Optimizer now has access to the scoring for SQL models, and makes preempt changes to access path choices.
There are furthermore various user interfaces that give the administrator visibility to the status of the accumulated SQL statement performance data and model scoring.
IBM's machine learning for zOS (MLz) offering is being used to remarkable upshot in Db2 version 12 to better the performance of analytical queries as well as operational queries and their associated applications. This requires management attention, as you must verify that your business is prepared to consume these ML and AI conclusions. How will you measure the costs and benefits of using machine learning? Which IT back staff must be tasked to reviewing the result of model scoring, and perhaps approving (or overriding) the results? How will you review and warrant the assumptions that the software makes about access path choices?
In other words, how well carry out you know your data, its distribution, its integrity and your current and proposed access paths? This will determine where the DBAs disburse their time in supporting analytics and operational application performance.

IBM partners are gearing up for a year of increased enablement, back and joint customer opportunities, as Part of deepened channel plans across Australia and unique Zealand.
According to Alison Freeman - universal manager of global business partners A/NZ at IBM - the vendor is doubling down on its partner ecosystem on both sides of the Tasman, amid plans to drive more software-as-a-service (SaaS) opportunities through the channel.
"Our priorities for this year are very lucid client segmentation, particularly from a software perspective on how and where they Go to market with their partners,” Freeman said. “There’s a roomy focus on embedded solution agreements - where partners are developing solutions with their technology.
"We’ve had some remarkable success and growth there in the past year. We’re getting the entire business behind achieving double digit growth for their partners in 2019, that’s their focus."
Last year, roomy Blue wanted partners to tolerate a larger wield on commercial business opportunities, an region the vendor will continue working through with partners specific to software.
"There’s a lot of labor going into that this year," added Freeman, when speaking to ARN on the sidelines of PartnerWorld at mediate in San Francisco. "We did that with a number of accounts eventual year, and this is a continuation.
"It’s a shift that allows partners to invest and bring on the perquisite people and skills. We’re working with them by client, on which partners they shift, based on their skills. It’s a roomy walkover and that’s how we’ll back them grow, which will furthermore back us grow."
Another point of focus for Freeman this year, is creating a better alignment with global system integrators (GSIs) such as KPMG, Wipro, HCL and DXC Technology.
This walkover may raise some intrigue over the competitiveness between IBM and such GSIs, but Freeman said the vendor was looking at how it can strengthen its go-to-market strategy in other areas of the business.
Another particular region that IBM is concentrating on is centred around providing more enablement and skills for partners, Freeman said.
“We’re providing the tools to enable their partners in the identical route that they skill their IBM teams,” she said. “We’re pushing better enablement, better connection with their partners, protection under deal registration and much quicker pricing."
The tech giant formally rolled out unique initiatives, including its Watson-based collaboration engine called IBM business partner Connect - which A/NZ partners piloted eventual year; My PartnerWorld; unique software deal registration and IBM Power Systems, LinuxONE and Z ‘In It to Win It’ incentives.
In San Francisco, John Teltsch - partner ecosystem universal manager at IBM - revealed that partners created more than 84,000 opportunities and drove over US$14 billion in revenue during 2018.
Such growth was triggered by the migration of multiple tools to My Sales Activity (MySA), a sole portal that helps partners manage their business with the vendor.
Enhancements were furthermore made to the PartnerWorld on-boarding process, cutting the time to on-board unique partners by 70 per cent in the process, resulting in the addition of 13,000 net unique ecosystem partners globally in 2018.
“From a partner point of view, we’re seeing a lot of growth in security, SaaS solutions, as well as the Internet of Things," Freeman added.
"We’re very stout in those areas. From a systems point of view, we’re seeing growth in storage and that’s another region where we’ll Look to bring on unique partners."
