Replication means that you can propagate data to diverse servers to preserve divide databases synchronized. information alterations captured at one server are later applied to one other (target) server, as illustrated in design 1.eleven. within the determine, the primary box suggests the source server and the fourth province shows the target server. The second and third packing containers comprise the "trap" and "follow" add-ons, respectively.
DB2 UDB has constructed-in assist for replication when supply and goal databases are partake of the IBM family unit, which includes Informix. For databases from different companies, corresponding to Oracle or SQL Server, the IBM DB2 information Integrator software is required.
Late remaining month, the AS/400 grew to become the first platform to implement IBM’s original industry regular conventional Database when DB2 UDB for AS/400 version four.four became launched with V4R4. Now other systems are following suit, as IBM announced DB2 commonplace Database 6.1 will quickly breathe attainable for OS/2, Linux, Unix, home windows NT, Microsoft home windows 95 and home windows ninety eight.
in a similar way, IBM has plans to unencumber DB2 UDB 6.0 for the OS/390 platform in addition to two original application additions to its DB2 household -- satellite edition and DB2 indecent over the plot -- this summer.
DB2 UDB for AS/four hundred four.four adheres to IBM’s traffic blueprint -- DB2 regularly occurring Database. This blueprint requires DB2 requirements in privilege here areas: utility aid, accessibility, extensibility, scalability and reliability.
in keeping with Van Symons, IBM AS/400 enterprise intelligence government, the determination to achieve in coerce a established Database gadget came about to execute sure indecent IBM shoppers are getting "among the finest items" and supply consistency in DB2 throughout indecent platforms.
released may moreover 21, DB2 UDB for AS/four hundred 4.four is compatible with V4R4 exclusively. Created with the persevered augment of e-business in intellect, DB2 UDB four.4 is designed to animate refined enterprise intelligence solutions and links corporate guidance to the net.
DB2 UDB 4.four facets a number of main improvements. One is scalability -- as DB2 UDB four.four has parallel lower back-up and repair, a feature that allows for AS/four hundred consumers to lower back up a terabyte statistics warehouse in one-and-a-half hours. to position this in viewpoint, the identical manner may gain taken as much as 40 hours on DB2 four.3, in accordance with Symons.
one other progress comes in the enviornment of statistics entry alternatives for Java purposes and web browsers. DB2 UDB 4.four additionally offers greater query optimization via Encoded Vector Indexing (EVI), a tool that allows advanced index structures for question functions. youngsters DB2 4.three protected EVI, it became not as advanced as four.4's version, based on Symons. "We had one customer with 1.three terabyte information who implemented EVI and it more suitable efficiency dramatically, doing it in 10 minutes in comparison to six to eight hours on DB2 4.3," he says.
in the fourth quarter of 1999, IBM plans to add one other feature to DB2 UDB four.4, an extensibility office referred to as demur Relational help. This feature can breathe achieve in at once on DB2 UDB four.4 and offers person-described data kinds and services. Symons says it turned into no longer launched with the other facets of DB2 UDB four.four in may additionally as a result of extra trying out had to breathe completed to breathe inevitable "precise fine."
whereas DB2 UDB 4.4 may breathe advantageous to AS/400 clients for lots of causes, Symons says the strongest asset might breathe featuring advice integration for e-business, ERP, Domino and enterprise intelligence. "you could engage an e-company software, achieve it into an order utility, circulate the records into a traffic intelligence application for analysis and then partake this analysis with the relaxation of the company by putting it into a Domino application so indecent clients can remark it," he says.
however the DB2 UDBs gain lots of the same aspects, there are some modifications, depending on the platform, in accordance with Hershel Harris, IBM's director of database technology. On the AS/four hundred platform, for example, DB2 has a flat of integration with the working system divide from most different IBM systems.
DB2 UDB 6.0 for OS/390 -- due June 25 -- is expected to office performance improvements for utilities, quicker utility processing, greater question performance, superior potential, extra constructed-in capabilities and more advantageous management capabilities.
the original points of DB2 UDB 6.1 -- due July 30 -- are geared towards extra potent e-enterprise solutions. application construction enhancements consist of a original photograph tool for edifice Java saved strategies, making it more straightforward and quicker to build and installation enterprise intelligence, ERP, CRM, e-commerce and integrated document functions.
Kent Milligan, IBM iSeries/i5 DB2 UDB knowledgeable, has been answering Search400.com's member questions for greater than five years. iSeries users gain asked Kent the identical questions time and again. with a view to obviate time, they now gain compiled the confiscate 10 questions requested about IBM iSeries/i5 DB2 for you. enact you've got a query that is no longer listed privilege here? put a question to Kent your IBM DB2 questions.
desk OF CONTENTS 1. suggested index not used 2. establishing a default library in IBM DB2 3. CHAR fields vs. VARCHAR 4. The True change between IBM DB2 databases 5. alternate the length of an current container 6. gaining access to an express file member the usage of SQL 7. Date formats & creating a table with SQL 8. what is the dissimilarity between DB2/400 and IBM DB2 UDB for the iSeries? 9. access data in SQL Server from the iSeries 10. How am i able to inform which indexes are getting used by IBM DB2 and the query optimizer to enrich performance?
1. recommended index not used
question: Operation Navigator recommends the usage of an index for SQL performance monitoring. I created the suggested index, however feels relish the paraphernalia does not exhaust it. I locate it unusual that the index is counseled after which now not used. is this common?
Milligan: in spite of the fact that the query optimizer advises growing an index, it would not always settle to exhaust it when creating its access plan. There are some causes for this:
The question optimizer doesn't always counsel the superb index. The understanding for here is that at present, handiest endemic preference is used when identifying what index to propound -- it doesn't yet believe breathe a partake of, order by using, or community by columns. consequently, after you create that informed index, it will probably not settle to exhaust it, because it remains no longer the faultless index. You may wish to manually intervene -- assess the query and agree with the breathe a partake of, community by using, and order through columns to determine what the example index is and create that index.
however, it could breathe recommending that index in order that it may well extract stats from the index to extra evaluate the most efficient access formulation. as an example, once the index has been created, it may breathe using data from the index to examine that question will revert many rows, therefore a desk scan is the competitively priced entry formula.
To enhanced engage into account the thought of a faultless index and the course indexes animate the query optimizer with facts, that you may study the white paper Indexing and facts thoughts for DB2 for i5/OS.
2. developing a default library in IBM DB2
question: How am i able to install a default library in IBM DB2 with the aim to now not exchange their SQL statements? really, we're migrating from IBM B2 UDB windows Server to the iSeries. truly, in home windows environment, their SQL statements Run smartly and with the SET current SCHEMAS = "EMPORIUM", they define default schemas in order that they shouldn't gain to explicitly specify it in each of their SQL statements. How am i able to enact this in an iSeries atmosphere? I should outline a library such as select ... FROM MCMLIB.COMMANDES the place. are you able to aid me?
Milligan: It depends on the software programming interface that you are the usage of. IBM DB2 UDB for iSeries delivered pilot for the SET current SCHEMA commentary in V5R2. The iSeries entry ODBC and JDBC drivers back connection keywords and properties to permit specifying a default library. here's an specimen of the ODBC connection keyword:
3. CHAR fields vs. VARCHAR
query: What are the example apply guidelines with reference to the exhaust of CHAR fields vs. VARCHAR fields on a IBM DB2 database for the iSeries?
i am constructing a brand original database for a .internet utility and i become because VARCHAR for some longer fields to shop storage. I had hoped that the VARCHAR container would moreover eradicate the trailing blanks from the string class fields. despite the fact, in my introductory assessments, it doesn't issue that VARCHAR has any gain an sequel on on these trailing blanks. Is there any atmosphere on the iSeries that may moreover breathe modified to automatically trim them?
Milligan: In frequent on IBM DB2 UDB for iSeries, VARCHAR data forms may quiet breathe used for columns containing lengthy descriptions or memos that aren't referenced very regularly. 50 bytes is doubtless the smallest size you would want to exhaust for a VARCHAR column. DB2 does gain to designate some extra bytes for each row with variable size columns to preserve track of the varying length data, so one of the vital space discounts may breathe consumed through these "additional monitoring" bytes. due to this overhead, the space rate reductions would handiest breathe notable on tables with a gigantic variety of rows.
4. The actual change between IBM DB2 databases
question: certainly one of their customers is starting a assignment with portable purposes solution atmosphere (PASE) beneath V5R3. The programmers tried to labor from that with C-program's to alternate advice with the endemic database and gain some essential issues with things akin to host variables and others. tips that can back to resolve these problems is hardly ever accessible -- mainly in Germany. The German IBM application service looks to breathe a gaggle of "we are iSeries; enact not know plenty concerning the relaxation of the IT world." can you back with counsel about the precise dissimilarity between the UDB databases in the UNIX/home windows and iSeries models?
Milligan: click on privilege here to gain information of the actual adjustments between the UDB databases within the UNIX/home windows and iSeries types.
5. change the size of an current box
query: am i able to trade the length of a box in a physical file without recompiling it?
Milligan: The most amenable solution to trade the length of an existing province is the CHGPF CL command.
6. having access to an express file member the exhaust of SQL
question: can you access an express file member the usage of interactive SQL? I are looking to access a multi-member *PF.
Milligan: sure, the easiest course is to create an alias for every secondary member that you necessity to access, after which exhaust the ALIAS identify in your SQL request. developing an alias is just a one-time setup operation.
right here's an instance:CREATE ALIAS mylib/a1 FOR mylib/myfile(mbr1)
choose * FROM mylib/a1 where f1>0
7. Date formats & creating a desk with SQL
question: i'm trying to create a desk the exhaust of SQL. i want the dates to breathe of the *u . s . a . (mm/dd/yyyy) structure. indecent of their information gain been created with DDS and indecent of their dates are DATFMT *u . s . a .. i would relish to create some original information with SQL, but I can't salvage the dates within the structure that they use. How am i able to enact that?
Milligan: The DATFMT can't breathe precise on SQL Create table. indecent date values, besides the fact that children, are kept by course of DB2 in the same inner structure regardless of the DATFMT this is specific on the column or box definition. When that statistics is examine from the SQL desk it could breathe converted to the output date structure divide with the aid of the software -- in your case the *united states structure.
8. what's the change between DB2/four hundred and IBM DB2 UDB for the iSeries?
question: what's the change between DB2/four hundred and IBM DB2 UDB for the iSeries?
Milligan: DB2/400 and DB2 UDB for iSeries are virtually the same aspect. iSeries (AS/400) changed into in a position to adopt the IBM DB2 UDB branding when it delivered lots of original database performance in V4R4 of OS/400, so the database turned into renamed from DB2/four hundred to DB2 UDB for iSeries in that free up.
that you may find extra tips on IBM iSeries and the DB2 UDB family privilege here.
9. access facts in SQL Server from the iSeries
query: can you inform me what I should entry statistics in a MS SQL database from the iSeries?
Milligan: The white paper you are seeking is Heterogeneous records access for iSeries purposes.
To access a non-DB2 facts source (together with Microsoft SQL Server) from an iSeries program written in any excessive-stage programming language, exhaust WebSphere guidance Integrator (previously DB2 suggestions Integrator - DB2 II). This product requires that the records access to breathe carried out with an SQL-primarily based interface reminiscent of CLI, embedded SQL or JDBC.
10. How am i able to inform which indexes are being used with the aid of IBM DB2 and the question optimizer to ameliorate efficiency?
question: How am i able to inform which indexes are getting used by IBM DB2 and the question optimizer to enhance efficiency?
reply: In V5R3, a brand original device was delivered to iSeries Navigator referred to as Index Evaluator. This original characteristic makes it effortless to research which indexes (and keyed analytic information) are helping your SQL and query efficiency and which indexes don't look to breathe pulling their weight. You can't depend on the thing timestamp "remaining used date" because that cost is not always up to date by using the question optimizer.
For each index described over the desk, the evaluator returns facts about the ultimate time an index turned into used within the implementation of a query and/or used to supply records in regards to the table information to the query optimizer. additionally, it returns a count number for the variety of instances the query optimizer used an index object.
under, you remark the output of the Index Evaluator, which is initiated by using correct-clicking on a table demur in iSeries Navigator and picking out the demonstrate Indexes assignment -- the assignment title is Indexes on V5R3).

Late final month, the AS/400 became the first platform to implement IBM’s original industry benchmark Universal Database when DB2 UDB for AS/400 Version 4.4 was released with V4R4. Now other platforms are following suit, as IBM announced DB2 Universal Database 6.1 will soon breathe available for OS/2, Linux, Unix, Windows NT, Microsoft Windows 95 and Windows 98.
Similarly, IBM has plans to release DB2 UDB 6.0 for the OS/390 platform as well as two original software additions to its DB2 family -- Satellite Edition and DB2 Everywhere -- this summer.
DB2 UDB for AS/400 4.4 adheres to IBM’s industry blueprint -- DB2 Universal Database. This blueprint calls for DB2 standards in the following areas: application support, accessibility, extensibility, scalability and reliability.
According to Van Symons, IBM AS/400 traffic intelligence executive, the determination to implement a Universal Database system came about to ensure indecent IBM customers are getting "top-of-the-line products" and provide consistency in DB2 across indecent platforms.
Released May 21, DB2 UDB for AS/400 4.4 is compatible with V4R4 exclusively. Created with the continued growth of e-business in mind, DB2 UDB 4.4 is designed to back sophisticated traffic intelligence solutions and links corporate information to the Web.
DB2 UDB 4.4 features several major improvements. One is scalability -- as DB2 UDB 4.4 has parallel back-up and restore, a feature that allows AS/400 customers to back up a terabyte data warehouse in one-and-a-half hours. To achieve this in perspective, the same procedure could gain taken up to 40 hours on DB2 4.3, according to Symons.
Another improvement comes in the zone of data access options for Java applications and Web browsers. DB2 UDB 4.4 moreover offers improved query optimization through Encoded Vector Indexing (EVI), a tool that allows advanced index structures for query applications. Although DB2 4.3 included EVI, it was not as advanced as 4.4's version, according to Symons. "We had one customer with 1.3 terabyte files who implemented EVI and it improved performance dramatically, doing it in 10 minutes compared to six to eight hours on DB2 4.3," he says.
In the fourth quarter of 1999, IBM plans to add another feature to DB2 UDB 4.4, an extensibility office called demur Relational Support. This feature can breathe installed directly on DB2 UDB 4.4 and provides user-defined data types and functions. Symons says it was not released with the other features of DB2 UDB 4.4 in May because additional testing had to breathe done to ensure "top quality."
While DB2 UDB 4.4 will breathe valuable to AS/400 users for a variety of reasons, Symons says the strongest asset will breathe providing information integration for e-business, ERP, Domino and traffic intelligence. "You can engage an e-business application, achieve it into an order application, pass the data into a traffic intelligence application for analysis and then partake this analysis with the relaxation of the organization by putting it into a Domino application so indecent users can remark it," he says.
Although the DB2 UDBs gain many of the same features, there are some differences, depending on the platform, according to Hershel Harris, IBM's director of database technology. On the AS/400 platform, for example, DB2 has a flat of integration with the operating system different from most other IBM platforms.
DB2 UDB 6.0 for OS/390 -- due June 25 -- is expected to feature performance improvements for utilities, faster application processing, better query performance, greater capacity, more built-in functions and improved management functions.
The original features of DB2 UDB 6.1 -- due July 30 -- are geared toward more powerful e-business solutions.

The biggest trend in IT careers is certification. You remark it everywhere you look... certification books dominate the bookstores, classroom training now guarantees a "pass," and IT professionals even note their emails with a list of their "certs."
Certification has arrived, no question. But as a DB2® professional, should you certify? Will it augment your abilities or animate your career? How can you enact it quickly and inexpensively? That final thought is key -- knowing the inside epic on DB2 certification before you proceed will deliver you a ton of time, stress and money. This article tells you what you necessity to know to settle if DB2 certification is for you, and if so, the secrets to doing it successfully, quickly and inexpensively.
Is certification "worth it"?
First, understand that an entire industry profits from certification. Trainers sell certification-oriented courseware, consultants thrust training, publishers market books, and vendors sell indecent the above. The upshot is that you can't engage most articles on certification at visage value. Let's engage a different tack. We'll try to ogle at the issue objectively, strictly from the IT professional's standpoint.
Why certify? Some enact it for the challenge of demonstrating their knowledge, or for the inner satisfaction that comes from mastery of the material. Whether a "certified DB2 developer" is better than one that is not certified is, to allege the least, highly debatable. What they can allege for sure is that if you certify you'll conclude up knowing more about DB2 than you did when you started.
Many certify for career benefits. If you view it this way, you necessity to:
Certify with a product that has major marketshare (and is on the upswing)
Investigate the marketability of the specific cert in which you're interested
On the first point, DB2 is the privilege choice. Most analysts agree that IBM has taken the lead in the database market away from Oracle (2).
Since database marketshare varies by platform, which platform you labor on should factor into your decision. DB2 completely dominates on mainframes and the IBM e-server® iSeriesTM (AS/400), with over 90% of the database marketshare for each. IBM comes in a tenacious second in UNIX® database marketshare, and a remote but growing third on Windows® Server. Data for Linux is sketchy, but DB2 appears paramount among the commercial databases (
A DB2 programmer wanted to shift into database administration. Getting her DBA cert bagged her the transfer.
A DB2 developer was powerful with JavaTM but felt too narrow because he didn't know about other approaches to DB2 application development. Getting the "developer" cert gave him the breadth he needed.
A stay-at-home mom wanted to reenter the workforce after a 10-year absence. She got certified and successfully leveraged this as "proof of currency" for her skills.
A original college grad desperately wanted to breathe a DBA but only received programming job offers. He proved his devotion to his goal by certifying as a DB2 DBA, which led to an entry-level DBA position.
A develope database veteran realized he needed to update his skills. Certifying both did this for him and supplied the proof. Age discrimination? His certification is as current as anyone else's.
Benefits must breathe weighed against costs. Discussion on current certification web sites relish Certification Magazine testify that most IT pros engage from two to five weeks studying for each test. You'll moreover gain to engage an" or="" how="" current.="" new="" what="" the="" couple="" prefer="" test="" cert="" into="" of="" know="" we="" certify="" cost="" for="" entirely="" remain="" a="" would="" certification.="" extending="" can="" thousands="" you="" certifying="" time="" learning="" as="" every="" make="" their="" serendipitous="" dollars="" knowledge="" spend="" if="" some="" few="" me="" dba="" not="" less="" discuss="" might="" opportunity="" dollar="" costs="" come="" more="" areas.="" use="" little="" to="" consider="" than="" once="" did="" releases="" other="" href="http://www.cramsession.com/" potentially="" run="" per="" but="" db2="">
As a contractor, I've directly benefited from certification. It gives me instant credibility with potential employers who've never met me and serves as my trump card for contractor interviews. It deals me an Ace in today?s extremely competitive job market.
Employers desperately want some benchmark measurement to quickly divide qualified from unqualified candidates. honest or not, they've adopted IT certifications as that yardstick. There is petite question that DB2 certification can animate your career, but ultimately each person must settle for him or herself whether it's worth the time and effort.
How to certify
You certify by passing one or more exams. The Roadmap to DB2 Version 8 certification in design 2 shows that you certify as a DB2 Database Associate by passing the required entry test, "DB2 Family Fundamentals, 700." Then engage any of the five additional certification exams, depending on your zone of interest. For example, to become a certified DB2 Database Administrator, pass "DB2 DBA for Linux, UNIX and Windows, 701," or certify as a mainframe DBA by passing "DB2 DBA for z/OS, 702." (Note- exam #702 will breathe available in 1st quarter 2004). You could moreover become a Certified Application Developer by passing "DB2 Family Applications Development, 703." Or certify in traffic Intelligence by taking "DB2 traffic Intelligence, 705," or specialize in the Content Manager via exam #442.
A really nice feature of the DB2 certification program is its modularity. After passing the ?DB2 Family FundamentalsÂ _ entry test #700, engage whichever exam(s) you like. Each one you pass gives you another certification.
IBM introduced several original features in the Version 8 certification program. First, there is a tripartite path yielding three ascending levels of DBA certification. This transparent path replaces the grab-bag of advanced ?Certified Solution ExpertÂ _ (CSE) exams in Version 7:
Table 1. The version 8 DBA certification path
DB2 Family Fundamentals
DB2 Database Administration
DB2 Advanced Database Administration
Advanced Database Administrator
The Version 8 program moreover introduces a lone test by which Version 7-certified DBAs can upgrade their certification. This is called ?DB2 for Linux, Unix and Windows Version 8 Upgrade Exam, 706.Â _ If you are a Version 7 certified DBA, you can either engage this original upgrade test, or simply pass the benchmark database administration exam #701 to upgrade your DBA cert to Version 8. The Upgrade test features fewer questions and is a shorter test, but many more study resources are available to animate you pass the benchmark DBA test, #701. In Version 8, IBM introduced a original test called the ?DB2 Problem Determination Mastery ExamÂ _. The exam covers problem determination using DB2 tools, for installation, configuration, communications and the like. Technically, it is not a certification exam, so it has no formal pre-requisites, nor enact you achieve an official certification by passing it. This test will breathe of powerful interest to those who certify as a DBA and want to strengthen (and prove) their problem identification and resolution abilities. The test costs only $40 and can breathe taken online via the web. For full information on this exam, and a free, downloadable set of nine study tutorials, visit the exam web page at Table 2.

What are the tests like?
Different candidates gain different experiences. Nevertheless, there exists some conventional wisdom on the subject. Compared to other database vendors' exams, the questions on the DB2 tests are difficult. But as Table 2 shows, the percentage of questions you necessity to reply correctly to pass is quite low. smack at IDUG conferences indicates a pass rate of about 75% for DB2 exams. recollect that indecent questions are multiple choice, so reply every one (there is no penalty for wrong answers, so at least guess at every question). The exam software allows you to imprint questions to revert to later, so you can skip hard questions and revert to them.
The time allowed for the exams is generous. You'll only consume the allotted time if you check your labor carefully. When you're done with the exam, click the Done button and the software instantly shows you whether you passed. You can print copies of your score on the spot via the LAN-attached printer. If you pass, IBM sends you a certificate via mail for printing and framing. You may moreover request one by mail.
What if you enact not finish the test in the allotted time? The screen freezes, a message tells you the exam has ended, and you'll remark the same pass or fail message you would if you had clicked the Done button yourself. Oops!
You must study for the exams. Being a DB2 guru won't animate if you don't study! The tests are broader than most IT pros' information base and moreover very specific in what they ask. They are designed to breathe rigorous.
Compared to competing database vendors' exams, the IBM DB2 tests look to gain fewer overly specific trivial pursuit questions and more questions requiring profound thought. The exams are intended to test your DB2 information and ability to design out DB2 problems (not just your ability to memorize what's in the certification study guides). My zeal is that they achieve this a petite better than competitors' tests. breathe prepared to tarry glacial while facing some tough questions. Remain secure in the information you'll only necessity a low percentage of questions answered correctly to pass.

What should you study?
Books that specifically target certification are your best bet. Their coverage matches what you?ll visage on the exams. Other DB2 books can breathe useful in pursuing your goal as well, but concentrate your pains on those designed to animate you certify.

Pool your resources
I've known several IT pros who successfully certified by creating a study group, or teaming up with a study buddy. You've seen by now that certifying requires some up-front labor in gathering resources and making judgments about what and how to study. The whole process can breathe a lot easier (and more fun) when done with friends.
If you engage this approach, breathe sure you've indecent got compatible goals. It doesn't matter much if one person in a study group drops out before completion, but a shared schedule is critical. indecent members must commit to taking the exams in the same order in about the same timeframe for the group to succeed.
