Replication means that you can propagate statistics to distinctive servers to preserve different databases synchronized. data changes captured at one server are later applied to yet another (target) server, as illustrated in pattern 1.eleven. within the determine, the first realm shows the source server and the fourth container suggests the goal server. The second and third bins comprise the "trap" and "follow" components, respectively.
DB2 UDB has constructed-in abet for replication when source and goal databases are a fragment of the IBM household, which comprises Informix. For databases from other providers, similar to Oracle or SQL Server, the IBM DB2 suggestions Integrator software is required.
Late final month, the AS/four hundred became the primary platform to implement IBM’s unique trade accustomed universal Database when DB2 UDB for AS/four hundred version four.4 changed into launched with V4R4. Now different structures are following spin well with, as IBM announced DB2 widespread Database 6.1 will soon be available for OS/2, Linux, Unix, windows NT, Microsoft home windows ninety five and windows 98.
in a similar fashion, IBM has plans to unencumber DB2 UDB 6.0 for the OS/390 platform in addition to two unique application additions to its DB2 household -- satellite tv for pc edition and DB2 utter over -- this summer.
DB2 UDB for AS/four hundred 4.four adheres to IBM’s trade blueprint -- DB2 widespread Database. This blueprint calls for DB2 necessities in the following areas: software aid, accessibility, extensibility, scalability and reliability.
in keeping with Van Symons, IBM AS/400 enterprise intelligence executive, the resolution to enforce a everyday Database system happened to originate certain utter IBM valued clientele are getting "one of the best items" and supply consistency in DB2 throughout utter platforms.
launched may too 21, DB2 UDB for AS/four hundred 4.four is compatible with V4R4 solely. Created with the persisted multiply of e-company in intellect, DB2 UDB four.four is designed to steer subtle enterprise intelligence options and hyperlinks company guidance to the net.
DB2 UDB four.4 facets a brace of most well-known improvements. One is scalability -- as DB2 UDB four.4 has parallel back-up and restore, a feature that allows AS/400 customers to lower back up a terabyte statistics warehouse in a single-and-a-half hours. to dwelling this in perspective, the very manner may infatuation taken as much as forty hours on DB2 four.3, in keeping with Symons.
one more evolution is available in the area of information entry options for Java functions and internet browsers. DB2 UDB 4.four too presents greater query optimization via Encoded Vector Indexing (EVI), a device that enables superior index constructions for question purposes. youngsters DB2 4.3 protected EVI, it turned into not as superior as four.4's edition, in response to Symons. "We had one client with 1.three terabyte info who implemented EVI and it more advantageous efficiency dramatically, doing it in 10 minutes in comparison to six to eight hours on DB2 4.3," he says.
within the fourth quarter of 1999, IBM plans to add one other office to DB2 UDB four.4, an extensibility feature referred to as protest Relational aid. This office will too be dwelling in at once on DB2 UDB 4.four and offers person-defined information types and services. Symons says it became no longer launched with the different features of DB2 UDB 4.4 in may additionally because additional testing needed to be finished to ensure "good excellent."
while DB2 UDB 4.4 may be effectual to AS/400 users for a number of explanations, Symons says the strongest asset will be proposing tips integration for e-company, ERP, Domino and company intelligence. "that you may remove an e-enterprise application, dwelling it into an order application, pass the records perquisite into a traffic intelligence software for evaluation and then partake this analysis with the leisure of the company by placing it perquisite into a Domino application so utter users can discern it," he says.
however the DB2 UDBs infatuation most of the very aspects, there are some ameliorations, depending on the platform, according to Hershel Harris, IBM's director of database technology. On the AS/400 platform, for example, DB2 has a stage of integration with the operating gadget distinct from most different IBM platforms.
DB2 UDB 6.0 for OS/390 -- due June 25 -- is expected to office efficiency advancements for utilities, faster utility processing, more desirable query efficiency, greater means, more built-in services and more desirable management services.
the brand unique elements of DB2 UDB 6.1 -- due July 30 -- are geared towards greater powerful e-enterprise options. utility edifice enhancements consist of a brand unique image instrument for edifice Java kept approaches, making it less difficult and quicker to construct and install company intelligence, ERP, CRM, e-commerce and built-in doc purposes.
Kent Milligan, IBM iSeries/i5 DB2 UDB expert, has been answering Search400.com's member questions for greater than five years. iSeries clients infatuation requested Kent the identical questions many times. as a way to rescue you time, they infatuation now compiled the exact 10 questions asked about IBM iSeries/i5 DB2 for you. result you infatuation got a question it really is now not listed here? request Kent your IBM DB2 questions.
table OF CONTENTS 1. counseled index now not used 2. setting up a default library in IBM DB2 three. CHAR fields vs. VARCHAR 4. The precise change between IBM DB2 databases 5. exchange the size of an latest container 6. gaining access to an specific file member the usage of SQL 7. Date formats & making a desk with SQL eight. what is the change between DB2/400 and IBM DB2 UDB for the iSeries? 9. access facts in SQL Server from the iSeries 10. How can i disclose which indexes are getting used through IBM DB2 and the query optimizer to multiply performance?
1. suggested index not used
query: Operation Navigator recommends the usage of an index for SQL efficiency monitoring. I created the advised index, but it feels infatuation the materiel would not exhaust it. I locate it ordinary that the index is counseled and then not used. is that this ordinary?
Milligan: besides the fact that the query optimizer advises developing an index, it would not always pick to exhaust it when growing its entry plan. There are some explanations for this:
The question optimizer does not utter the time advise the exemplar index. The judgement behind this is that presently, only endemic preference is used when settling on what index to hint -- it doesn't yet accept as wholehearted with join, order by means of, or neighborhood by columns. consequently, after you create that advised index, it may possibly no longer pick to exhaust it, as it continues to be now not the best index. You could requisite to manually intervene -- examine the question and believe the join, neighborhood with the aid of, and order by columns to investigate what the best index is and create that index.
alternatively, it may be recommending that index so that it might extract stats from the index to extra evaluate the surest entry method. for instance, as soon as the index has been created, it could be the usage of records from the index to examine that question will revert many rows, as a result a desk scan is the low-priced access system.
To greater infatuation in intellect the thought of a perfect index and the way indexes back the query optimizer with facts, that you may read the white paper Indexing and records thoughts for DB2 for i5/OS.
2. developing a default library in IBM DB2
query: How can i install a default library in IBM DB2 with the objective to no longer trade their SQL statements? in fact, they are migrating from IBM B2 UDB home windows Server to the iSeries. really, in windows atmosphere, their SQL statements Run smartly and with the SET existing SCHEMAS = "EMPORIUM", they define default schemas so that they won't infatuation to explicitly specify it in each and every of their SQL statements. How can i result that in an iSeries atmosphere? I deserve to outline a library corresponding to pick ... FROM MCMLIB.COMMANDES where. can you abet me?
Milligan: It depends upon the application programming interface that you're the exhaust of. IBM DB2 UDB for iSeries introduced abet for the SET latest SCHEMA remark in V5R2. The iSeries access ODBC and JDBC drivers back connection key terms and properties to enable specifying a default library. perquisite here's an instance of the ODBC connection key phrase:
three. CHAR fields vs. VARCHAR
query: What are the most profitable apply guidelines with reference to the usage of CHAR fields vs. VARCHAR fields on a IBM DB2 database for the iSeries?
i'm constructing a unique database for a .web software and that i turned into due to the fact VARCHAR for some longer fields to rescue storage. I had hoped that the VARCHAR realm would too eradicate the trailing blanks from the string classification fields. although, in my initial assessments, it does not appear that VARCHAR has any infatuation an result on on these trailing blanks. Is there any environment on the iSeries that will too be modified to automatically trim them?
Milligan: In generic on IBM DB2 UDB for iSeries, VARCHAR data kinds may soundless be used for columns containing long descriptions or memos that don't appear to be referenced very regularly. 50 bytes is likely the smallest length you possibly can are looking to exhaust for a VARCHAR column. DB2 does must earmark some additional bytes for each and every row with variable length columns to maintain song of the various length information, so one of the vital space rate reductions will be consumed by means of these "added monitoring" bytes. as a result of this overhead, the space imprint downs would best be major on tables with a vast number of rows.
4. The wholehearted change between IBM DB2 databases
question: certainly one of their customers is starting a undertaking with transportable functions respond ambiance (PASE) beneath V5R3. The programmers tried to work from that with C-software's to exchange tips with the endemic database and infatuation some major issues with things equivalent to host variables and others. suggestions that can aid to resolve these complications is rarely attainable -- mainly in Germany. The German IBM application carrier seems to be a bunch of "we are iSeries; result not know lots about the rest of the IT world." can you aid with information in regards to the wholehearted change between the UDB databases in the UNIX/windows and iSeries types?
Milligan: click here to learn the actual transformations between the UDB databases in the UNIX/home windows and iSeries types.
5. trade the length of an existing field
question: am i able to change the size of a realm in a physical file without recompiling it?
Milligan: The most excellent technique to trade the size of an present realm is the CHGPF CL command.
6. accessing an specific file member using SQL
question: are you able to access an specific file member the exhaust of interactive SQL? I requisite to entry a multi-member *PF.
Milligan: sure, the simplest way is to create an alias for each secondary member that you requisite to access, and then exhaust the ALIAS identify for your SQL request. developing an alias is simply a one-time setup operation.
here's an instance:CREATE ALIAS mylib/a1 FOR mylib/myfile(mbr1)
choose * FROM mylib/a1 the dwelling f1>0
7. Date codecs & making a desk with SQL
query: i am making an attempt to create a table the exhaust of SQL. i want the dates to be of the *united states (mm/dd/yyyy) format. utter of their data infatuation been created with DDS and utter of their dates are DATFMT *u . s . a .. i requisite to create some unique information with SQL, however I can not procure the dates within the structure that they use. How can i result that?
Milligan: The DATFMT can not be specified on SQL Create desk. utter date values, despite the fact, are saved by way of DB2 in the identical inside layout in spite of the DATFMT that is targeted on the column or container definition. When that facts is read from the SQL table it should be converted to the output date layout specified via the utility -- for your case the *us of a format.
eight. what is the distinction between DB2/400 and IBM DB2 UDB for the iSeries?
query: what's the distinction between DB2/four hundred and IBM DB2 UDB for the iSeries?
Milligan: DB2/four hundred and DB2 UDB for iSeries are very nearly the identical thing. iSeries (AS/400) was in a position to undertake the IBM DB2 UDB branding when it delivered loads of unique database performance in V4R4 of OS/four hundred, so the database became renamed from DB2/400 to DB2 UDB for iSeries in that liberate.
that you could find greater assistance on IBM iSeries and the DB2 UDB household perquisite here.
9. access facts in SQL Server from the iSeries
query: are you able to disclose me what I deserve to access data in a MS SQL database from the iSeries?
Milligan: The white paper you are searching for is Heterogeneous records access for iSeries applications.
To entry a non-DB2 information source (including Microsoft SQL Server) from an iSeries program written in any excessive-level programming language, exhaust WebSphere suggestions Integrator (previously DB2 assistance Integrator - DB2 II). This product requires that the records entry to be performed with an SQL-primarily based interface comparable to CLI, embedded SQL or JDBC.
10. How can i disclose which indexes are being used by means of IBM DB2 and the question optimizer to improve performance?
question: How can i disclose which indexes are being used by IBM DB2 and the query optimizer to improve efficiency?
reply: In V5R3, a unique instrument become brought to iSeries Navigator called Index Evaluator. This unique feature makes it convenient to research which indexes (and keyed ratiocinative information) are helping your SQL and query performance and which indexes aren't pulling their weight. You cannot import on the protest timestamp "ultimate used date" because that price isn't utter the time up-to-date via the query optimizer.
For each index defined over the desk, the evaluator returns facts in regards to the final time an index was used within the implementation of a question and/or used to give facts in regards to the table information to the query optimizer. furthermore, it returns a import number for the number of times the query optimizer used an index object.
beneath, you discern the output of the Index Evaluator, which is initiated by way of appropriate-clicking on a desk protest in iSeries Navigator and determining the betray Indexes assignment -- the stint identify is Indexes on V5R3).

It has been said that one of the fastest growing crimes in America today is an act known as “identity theft.” By obtaining the perquisite information, an identity thief can borrow big amounts of money or originate expensive purchases in someone else's name, leaving that individual in alarming monetary shape. So, just where can this information, which should be closely guarded, be found? Chances are it has been collected and entered into some body's database. (Think about the paperwork you had to fill out the final time you started a unique job, opened a unique bank account, or bought a unique car. More likely than not, the information you provided on that paperwork—information that identifies who you are—was transferred to a database for future use.)
Every database management system must be able to protect data against unauthorized access and/or modification. DB2 Universal Database uses a combination of external security services and internal access control mechanisms to effect this vital task. In most cases, three different levels of security are employed: The first level controls access to the instance a database was created under, the second controls access to the database itself, and the third controls access to the data and data objects that reside within the database.

The biggest trend in IT careers is certification. You discern it everywhere you look... certification books dominate the bookstores, classroom training now guarantees a "pass," and IT professionals even symptom their emails with a list of their "certs."
Certification has arrived, no question. But as a DB2® professional, should you certify? Will it multiply your abilities or abet your career? How can you result it quickly and inexpensively? That final thought is key -- knowing the inside anecdote on DB2 certification before you proceed will rescue you a ton of time, stress and money. This article tells you what you requisite to know to pick 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 propel training, publishers market books, and vendors sell utter the above. The upshot is that you can't remove most articles on certification at pan value. Let's remove a different tack. We'll try to gape at the issue objectively, strictly from the IT professional's standpoint.
Why certify? Some result 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 yelp the least, highly debatable. What they can yelp for certain is that if you certify you'll terminate up knowing more about DB2 than you did when you started.
Many certify for career benefits. If you view it this way, you requisite 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 perquisite choice. Most analysts harmonize that IBM has taken the lead in the database market away from Oracle (2).
Since database marketshare varies by platform, which platform you work 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 tough second in UNIX® database marketshare, and a remote but growing third on Windows® Server. Data for Linux is sketchy, but DB2 appears preeminent 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 worthy 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 unique college grad desperately wanted to be 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.

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 criterion measurement to quickly sever qualified from unqualified candidates. unbiased or not, they've adopted IT certifications as that yardstick. There is dinky question that DB2 certification can abet your career, but ultimately each person must pick 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 pattern 2 shows that you certify as a DB2 Database Associate by passing the required entry test, "DB2 Family Fundamentals, 700." Then remove any of the five additional certification exams, depending on your area 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 be available in 1st quarter 2004). You could too 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, remove whichever exam(s) you like. Each one you pass gives you another certification.
IBM introduced several unique 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 Database Administration
DB2 Advanced Database Administration

The Version 8 program too introduces a solitary 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 remove this unique upgrade test, or simply pass the criterion 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 abet you pass the criterion DBA test, #701. In Version 8, IBM introduced a unique 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 result you achieve an official certification by passing it. This test will be of worthy 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 be taken online via the web. For plenary 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 infatuation 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 requisite to respond correctly to pass is quite low. sustain at IDUG conferences indicates a pass rate of about 75% for DB2 exams. remember that utter questions are multiple choice, so respond 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 work 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 too request one by mail.
What if you result not finish the test in the allotted time? The screen freezes, a message tells you the exam has ended, and you'll discern the very 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 abet if you don't study! The tests are broader than most IT pros' information groundwork and too very specific in what they ask. They are designed to be rigorous.
Compared to competing database vendors' exams, the IBM DB2 tests appear to infatuation fewer overly specific petty pursuit questions and more questions requiring deep thought. The exams are intended to test your DB2 information and aptitude to pattern out DB2 problems (not just your aptitude to memorize what's in the certification study guides). My emotion is that they achieve this a dinky better than competitors' tests. be prepared to tarry chilly while facing some tough questions. Remain secure in the information you'll only requisite 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 pan on the exams. Other DB2 books can be useful in pursuing your goal as well, but concentrate your application on those designed to abet you certify.

Free testing at conferences:
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 work in gathering resources and making judgments about what and how to study. The all process can be a lot easier (and more fun) when done with friends.
If you remove this approach, be certain you've utter 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. utter members must consign to taking the exams in the very order in about the very timeframe for the group to succeed.
