the brand new release besides brings profit for SQL replication and federation with DB2 on Linux, Unix, and windows (DB2 on LUW), with Informix Dynamic Server, and with web features. Enhancements to DB2 pureXML, together with the potential to encompass XML in enterprise analytics, are besides blanketed, IBM says.
builders can additionally buy talents of election SQL language syntax in the new unencumber, including option SQL language syntax for DELETE statements, the RID_BIT scalar feature, and the FOR update clause for select INTO statements, IBM says. New exist a section of methods, as well as a new scripting and command line construction tool, CLPPlus, are additionally covered within the new free up.

newsIBM DB2 Will goal Oracle Database developers IBM this week introduced a new edition of its flagship DB2 database with software on the pass to supply compatibility with applications built for Oracle databases.
Embedded in IBM's impending DB2 9.7, code-named "Cobra" and slated for unlock in June, is software that offers compatibility with EnterpriseDB Corp.'s Postgres Plus superior Server database, which helps every bit of Oracle records kinds, SQL syntax, semantics and other applications built with Oracle PL/SQL stored techniques. Postgres superior Server is developed on the open source PostgreSQL database.
"The set of applied sciences we've got delivered will aid builders of customized purposes and packaged applications installation to DB2," said Bernie Spang, director of strategy, analytics and facts management for IBM's utility neighborhood.
For IBM, it exist the primary time the company has licensed know-how from a issuer of open source database utility, though EnterpriseDB founder Andy Astor observed the utility embedded in DB2 is in response to proprietary code.
"this is now not an open supply play," Astor mentioned. "every thing else they result is open supply but that is one of the approaches they get their money, through selling that compatibility know-how each to vendors enjoy IBM, during this case, and to clients within the variety of Postgres Plus superior Server."
EnterpriseDB features to a number of valued clientele including FTD and Sony online leisure that occupy migrated purposes developed for Oracle databases to Postgres Plus. The cope with IBM "gives them with proven performance for enabling compatibility between DB2 and functions written for Oracle," referred to 451 community analyst Matthew Aslett in an e mail.
"Database migrations are complicated, time-consuming, expensive and rare, so any functionality that makes the procedure more convenient is going to exist welcomed via those businesses that are organized to get the soar," he added.
The licensing pact is the first by using EnterpriseDB, but Astor spoke of others are being negotiated.
IBM is hoping the rush will motivate more clients to migrate to its InfoSphere Warehouse 9.7 commerce edition, a data-cleansing and enterprise analytics platform in keeping with DB2 and know-how IBM received from Cognos.
the brand new unlock is targeted at bringing statistics mining, analytics and cubing to departments of enterprises and smaller agencies, Spang talked about. additionally new in DB2 is advocate for performing simultaneous transactions across XML and relational records.

although that db2set has been around for a while, it seems that db2set isn't every bit of the time smartly understood. in keeping with IBM’s documentation, the IBM DB2 Profile Registry command (db2set) allows for centralized manage of environmental variables. study on to study more...
one of the crucial first troubleshooting alternatives I ever had with DB2 LUW involved db2set. That was with DB2 UDB 5.0 and was more than a decade in the past. Now I’m using DB2 9.7 and that i’m quiet using db2set, so it definitely has some staying vigor. besides the fact that children that db2set has been round for ages, in speakme to different DBAs it appears that db2set is not every bit of the time neatly understood.
in line with IBM’s documentation, the DB2 Profile Registry command (db2set) allows for for centralized ply of environmental variables. There are several degrees of the Profile Registry.
From very own event, I occupy institute some unique things about db2set. once, when dissimilar DBAs occupy been making an attempt to expend db2set on the selfsame time to update values for a similar instance, my db2set -all output displayed inconsistent values. This turned into without vicissitude mounted by using easily choosing the complete set of updates they desired to get and then having one grownup result the entire db2set instructions. Of route, that became on a previous free up of DB2 so it may possibly no longer exist an issue with DB2 9.7.
I besides institute out that DB2SYSTEM and DB2INSTDEF, that are set at the world level, can give some respectable assistance. simply by means of looking on the DB2SYSTEM variable, i was as soon as able to determine that an entire atmosphere had been install incorrectly using a file materiel reproduction strategy versus a common and supported DB2 approach. That one discovery saved me lots of troubleshooting time.Are you and DB2SET Acquainted?
Most of us occupy had as a minimum some publicity to db2set. exist cognizant this?$> db2set db2comm=tcpip
Or probably in case your shop uses SAP, you occupy used this special aggregate registry variable which units a large number of values by means of one profile registry replace.$> db2set DB2_WORKLOAD=SAP however occupy you used this one? $> db2set -lr
If now not, you could exist missing some respectable guidance. When using the –lr option with db2set, which you can notice every bit of of the supported registry variables that can exist institute for us with the product edition for this installing.
Who can replace the DB2 profile registry? The avow depends on the operating equipment. On a UNIX platform, somebody who holds SYSADM for the illustration can replace registry values for that illustration. On windows, when prolonged safety is enabled, a SYSADM who belongs to the DB2ADMNS group can set and replace the registry values.
When the expend of the DB2 Command Line to change a DB2 Profile variable cost on the local or default illustration degree, the command is quite simply:db2set <variable>=<cost>
illustration:db2set DB2COMM=tcpip db2stop db2start
(whereas the brand new price for DB2COMM is automatically stored within the profile registry, the change isn't utilized unless a restart.)DB2SET Helps Itself
in case you want extra suggestions, it's simple to secure it. DB2SET provides a command line profit election it truly is in reality valuable! just adding a question notice to the cessation of the db2set command returns a plenary expose of tips.
$> db2set ?$> db2set ? DBI1300N db2set displays, sets, or eliminates DB2 profile variables. db2set [variable=[value]] [-g|-i instance [db-partition-number]] [-all] [-null] [-r [instance] [node-number]] [-n DAS node[-u user[-p password]]] [-l|-lr] [-v] [-ul|-ur] [-?|-h]
The command alternate options are:-g access the world profile variables. -i Specifies the example profile to expend in its spot of the latest or default. -n Specifies the faraway DB2 Administration Server node identify. -u Specifies the person identity to expend for the Administration Server attachment. -ul access the person profile variables -ur Refreshes user profile variables -p Specifies the password to get expend of for the admin server attachment. -r Resets the profile registry for the given instance. The default/existing example can exist used if no one is equipped. -l Lists every bit of example profiles. -lr Lists every bit of supported registry variables. -v Verbose mode. -? shows the command advocate message. -h identical as -? option. -all shows every bit of occurrences of the local atmosphere variables as described in: * The atmosphere, denoted via [e] * The user stage registry, denoted via [u] * The node flat registry, denoted by means of [n] * The instance flat registry, denoted via [i] and * The international degree registry, denoted via [g] -null units the variables price to null on the particular registry flat to withhold away from searching up the cost in the subsequent registry degree as described in the variable price search order. Notes: * db2set with no variable identify shows every bit of defined variables. * db2set <variable> displays <variable>'s cost. * db2set <variable>= (nothing) deletes the <variable>. * db2set <variable>=<value> modifies the <variable>'s cost. * db2set <variable> -null units <variable>'s price to NULL. * db2set <variable> -all shows every bit of described <variable>'s values. * db2set -ur refreshes the present user profile. * db2set <variable> -ul shows described <variables> on the user level. * db2set -all displays every bit of described variables in every bit of registry degrees.
essentially the most commonplace technique to assess the set of values stored in the DB2 Profile Registry is to expend the db2set –all command. privilege here’s an instance.db2set -all [e] DB2PATH=C:\software information\IBM\SQLLIB [i] DB2PROCESSORS=0,1 [i] DB2INSTPROF=C:\ProgramData\IBM\DB2\DB2COPY1 [g] DB2_COMPATIBILITY_VECTOR=MYS [g] DB2_EXTSECURITY=sure [g] DB2SYSTEM=LOCKSMITH [g] DB2INSTDEF=DB2 [g] DB2ADMINSERVER=DB2DAS00
supplied you've got the usurp authority, that you could additionally expend the SYSIBMADM.REG_VARIABLES administrative view, which will besides exist queried to secure the registry settings from every bit of database partitions. The result set might possibly exist different from what you can notice when the usage of the db2set -all. The mismatch can happen if a DB2 registry variable is configured the expend of the db2set command after the instance has been every bit of started. REG_VARIABLES best returns the values that had been in result when the illustration became began.
here’s an instance:db2 "opt for CHAR(REG_VAR_NAME,35) AS REGVAR, CHAR(REG_VAR_VALUE,35) AS value, degree FROM desk(REG_LIST_VARIABLES()) AS REG ORDER via three,1" REGVAR price stage ------------------------- ----------------------------------- ----- DB2PATH C:\application info\IBM\SQLLIB E DB2ADMINSERVER DB2DAS00 G DB2INSTDEF DB2 G DB2SYSTEM LOCKSMITH G DB2_COMPATIBILITY_VECTOR MYS G DB2_EXTSECURITY yes G DB2INSTPROF C:\ProgramData\IBM\DB2\DB2COPY1 I DB2PROCESSORS 0,1 I pondering about the Future
With each new version of DB2, the profile registry options are topic to exchange. So previous to upgrading, or performing a new install, one investigation I undertake is to exist trained in regards to the a considerable number of options for db2set as they solemnize to that specific product stage. The IBM DB2 counsel middle is every bit of the time my resource for that. For DB2 9.7, that you may find advice for the db2set profile registry alternate options birth at http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp?subject matter=/com.ibm.db2.luw.admin.regvars.doc/doc/c0004934.html. Drilling down from that link will present you every bit of the particulars.ultimate techniques
on occasion there are some very advantageous Profile Registry variables that can besides exist set to enhance performance or profit DBAs remedy application concerns. It’s enjoy opening a flabbergast reward, you comprehend it may exist whatever thing respectable, however you’re simply no longer confident how first rate it can exist except you appear. once you unwrap the information about db2set, you're going to buy into account how to expend that knowledge as a present to your DB2 environment.

As one of Europe's leading suppliers of DB2 services, my organization has been involved in a vast number of technical advocate calls and incidents with their customers. These situations achieve from the tragic to the downright bizarre, but each and every one can exist avoided (or at least mitigated) with the privilege processes and procedures in place.
In this column, I'd enjoy to buy you on a quick tour of some of my favourite DB2 advocate incidents and war stories for Linux, UNIX and Windows. every bit of of these actually happened, but I occupy omitted some details in order to withhold them suitably anonymous. With thanks to the many Triton consultants that contributed, and quiet abide the scars of their involvement.Issue 1: The Law of Unintended Consequences
This one started (as many do) with a muster for profit from one of their DB2 customers. every bit of of the rows had been deleted from a captious table in a pre-production environment. The junior DBA had bravely admitted to accidentally connecting to the wrong system to limpid down the table, but couldn't understand why he'd been able to delete the rows as he shouldn't occupy had the authority to result so.
In every bit of such circumstances, the priority is always to secure the data back and the developers working again. This was quickly accomplished with a criterion recovery using a recent backup and no problems were encountered. They then turned their attention to the job of figuring out how the junior DBA had been able to delete the data in the first place.
After much investigation, they discovered the following:
Needless to say, the FED_NOAUTH parameter was rapidly set back to NO and bona fide authentication checking was reinstated.
Many of us expend a lot of time tuning databases and applications, but how often result they deem about their own performance? Time and again, they notice examples of DBAs and advocate staff that are taking the long pass round and using more time than necessary to achieve routine tasks. One particular aspect of this is the expend of the command line versus a GUI such as the DB2 Control Center.
I know plenty of people who are passionate supporters of the GUI, and indeed it can exist a very respectable pass to quickly accomplish one-off activities such as an ad-hoc reorg. However, there are plenty of situations where expend of the command line (or better still, DB2 commands embedded in a simple script) will get much more sense. The job is then easily repeatable, actions and their results can exist recorded (by redirecting the output to a text file), and a script is a lot easier to hand over to a colleague than pages of instructions and GUI screenshots!
A common example is the routine process of promoting database objects between development, test and production environments. A respectable script can accomplish that job in a fraction of the time needed to result the selfsame thing from the GUI, and utilities such as db2look can exist used to compare database structures to ensure consistency.
Many of us are working in environments where the SQL presented to DB2 is not written directly by a human being, but generated automatically by a tool. Common examples include Java frameworks, 3GLs and commerce intelligence tools such as Cognos in this example.
In this example, the customer reported a long elapsed time for a Cognos-generated query (over 30 minutes) running against a DB2 9.5 database, with the query consistently failing due to the DB2 temp space being exceeded. The users repeatedly increased the temp space and re-tried the query, but with exactly the selfsame result each time. In desperation they even ran the DB2 Index Advisor and created additional indexes, but temp space quiet blew before the query finished.
A advocate incident was opened, and analysis using a third-party query monitoring implement showed a very tall query execution cost. Further examination of the actual SQL being generated by Cognos showed a Cartesian unite of two tables, each with more than 25M rows in, with the new indexes not being used at all. Going back to the Cognos definitions showed a key database relationship had not been defined to Cognos, so it had to filter vast amounts of data locally.
The solution was simply to re-work the Cognos report definitions to add the missing database relationships. This caused Cognos to generate remedy unite predicates and the reports ran to successful completion in under 2 minutes. The developers were besides educated to spy at both the Cognos and generated "native" SQL in the future.
This particular issue happened in a development environment where DB2 for LUW 9.7 was the back-end database, but it could really occupy been any other RDBMS. A highly-skilled offshore team was developing a new application, with a local system administration team looking after the OS support.
Triton was originally contacted as a one-off exercise, as the developers were complaining about consistently indigent query performance and asking to walkaway to another RDBMS as DB2 was clearly not up to the job. They institute a surprisingly common situation: the team of developers, highly skilled in SQL and able to formulate tangled queries, were completely focused on the application code and no one was looking after the data. Consequently, there was no backup regime in place, no RUNSTATS or other housekeeping, and the only indexes were primary ones created when the database was first designed. Not surprising then that the query performance had been so indigent — no one of the tables had ever had stats collected.
Further questioning revealed that the developers had no DB2-specific knowledge whatsoever, and no wish to learn. As far as they were concerned, the database was a black box that they could pitch SQL at and secure data back.
We quickly implemented a basic set of automated housekeeping procedures that resolved the performance issues and made the developers happy. However, in the process they uncovered a lot of data quality issues (such as developers coding inefficient SQL to secure around duplicate data that shouldn't exist). A more formal design review of the database was conducted, and they were asked to provide an ongoing remote DBA service to avoid the selfsame issues arising in the future.
This is a much example of how "finger trouble" can cause red faces and application outage. The Senior DBA for a major public services application took his annual vacation, leaving a recently-trained Junior DBA in charge. Responding to a request to limpid down a development database, the Junior DBA fired up his telnet session, dropped and re-created the apposite database and congratulated himself on a job well done ... until the phones started ringing with users complaining that they couldn't expend the production application. The DBA had accidentally dropped a captious production database, thinking that he was connected to the UAT system.
To his credit, the DBA was quick to own up to the mistake and Triton was called in to assist with the recovery. This was conducted without further drama, but the best section of a commerce day had been lost by the time everything was back to normal.
We received a frantic muster one evening from a customer asking for immediate help. DB2 had "hung" and no activity could exist performed on the production database. As the OLTP system had a 24x7 online SLA, it was not surprising that the senior management was waiting when they arrived at the customer site. Upon investigation, it became patent that DB2 was looking for an active transaction log file that had gone "missing" and was nowhere to exist found.
After investigation, the Story started to become clearer. In a desperate attempt to create some space on the production database server, a junior sysadm had stumbled upon the DB2 transaction log directory (which in this case housed both the active and archived logs) and thought, "Hmm, this directory could result with some clean-up." Using his judgment of the age of the files, he deleted some of them. He gained space but unfortunately lost an active transaction log file in the process.
Despite their advice that a restore from a previous backup was the only solution to their problem, the local Oracle DBA with some DB2 knowledge tried various methods to "trick" DB2, enjoy creating a dummy log file with the selfsame name as the missing one, not knowing that the DB2 transaction log files occupy header information within them. After a lot of delay, it was finally agreed to carry out a restore from the most recent backup. This proved degree of a challenge since no backups were stored on disk. So, the remedy tape had to exist institute and mounted. The restore and subsequent rollforward to a consistent point in time did successfully buy spot and sighs of relief could exist heard in the early morning hours. Even though some hours of commerce had been lost, jobs had been saved! And yes, even the junior sysadm was allowed to linger on since he owned up to his mistake...
Here's a nightmare advocate scenario: a broken database on an unsupported version of DB2, with no backups or log files to retrieve the database.
An erroneous script had deleted a few transaction log files that had a 'last changed' date of more than 45 days. The selfsame script had caused other errors and a database restart was required, but the database did not start. The database was looking for an ancient log file, which had just been deleted by the script. As the policy was to retain the backups and archive logs for 30 days, this log file was deleted from the archive logs too.
The database was tiny — less than 50GB. Nevertheless, it was a very necessary one, with a number of web facing apps relying on it for necessary features. To get matters worse, the version of DB2 in expend had passed its "End of Service" date, so DB2 advocate was not willing to investigate (though they were cheerful to guide).
When they got involved a few hours after the incident, panic had set in. Based on information available (saved snapshots and db2diag.log file), they were able to conclude that there was a transaction which started in the log file the database was looking for. This transaction was never completed. The rate of change of data was so small, the configured log numbers could fade on for more than 45 days.
The options available were to extract the data from the latest backup image (using tools enjoy tall Performance Unload) or extract the data from the damaged database (using db2dart). The latter option was chosen as this would allow us to retrieve the most recent data.
Without further delay, they ran db2dart on the database to check for any errors and to secure the Tablespaceid, Tableid and the total number of pages allocated to each table. They were then able to expend the information to build the db2dart command with the DDEL option to extract the data in delimited format. db2dart with the DDEL option is interactive (i.e., when the command is run, it prompts for the tablesapce id, tableid and the page achieve to extract the data). This meant that the extract could not exist scripted but had to exist done manually for each of the 300+ tables.
Once that mind-numbing job was complete, they created a new database with the DDL that was available (thankfully, they had a db2look output from the production database less than a week before the incident). Finally, they loaded the extracted data to the new database and ran runstats on the table and indexes.
After a few hiccups and 15 hrs of db2dart, import/load, runstats and data fixes, the database was available for the application. The database was down for more than 20 hours, but it was back in once piece with nearly no data loss. Quite an achievement under the circumstances!
We often occupy to request customers for the DB2 diagnostic log file (db2diag.log), only to exist told "it's too large to send" or "it's taking too long to open." This is because the DB2 diagnostic files occupy been appended only since time immemorial, their growth only restricted by the maximum space available in the file system they reside in. The only pass to curb this growth would exist to rename the files, which would then obligate the creation of new ones. Scripts had to exist written to automate this process and to delete ancient files after a certain period. Many customers didn't occupy these processes in place.
With the advent of DB2 9.7, every bit of this is now history! The new DIAGSIZE database manager parameter allows a DBA to control the maximum sizes of the DB2 diagnostic log and administration notification log files. When this parameter is set to a non-zero value (which is the default pre-DB2 9.7 behaviour), a sequence of 10 rotating diagnostic log files and rotating administration notification log files (only on UNIX and Linux) are used. It is besides smart enough to antiseptic up ancient log files from the diagnostic log directory. When the 10th file is full, the oldest file is deleted, and a new file is created.
The customer was using HADR to a remote server for resilience, running in ASYNC mode to minimize the performance impact. No cluster software was used for monitoring/failover, but the HADR situation was being monitored on a regular basis using a shell script.
On the primary site, a few disks failed, which caused some of the tablespaces to exist withhold in "Rollforward Pending" State. Transactions accessing data in these tablespaces failed but the others were successful. The ultimate dash of the HADR situation monitoring script indicated a Peer State, and therefore it was decided to issue a TAKEOVER command on the DR Site to switch roles. When the application started, some transactions failed with the selfsame error as on the primary site — not good!
A list tablespaces command showed a number of tables in "Rollforward Pending" state. To secure out of the pending state, the ROLLFORWARD command was issued with the list of affected tablespaces. The rollforward was trying a retrieve a log, which was a few thousand logs older than the current one. Not surprisingly, this log was not available in the archive. After a few more tries, the ROLLFORWARD option was given up and the database was restored from the latest backup image and the application started.
So what happened? They went through the db2diag.log and the notification logs. They could notice that there were physical errors reported in some of the tablespaces on the DR site (HADR Standby) around 100 days prior to the incident. This was reported in the db2diag.log, and the affected tablespaces were "excluded from the rollforward set." Based on other entries in the db2diag file, they were able to corroborate that the log file requested for rollforward on the DR site was used at the time the physical errors occurred there. HADR continued to apply logs for the other tablespaces and was reporting to exist in "Peer" State. In reality, some of the tablespaces were being ignored.
I'll round off my top ten with one of the most basic issues they encounter, but unfortunately one of the most common. It's unbelievable how many DB2 sites don't occupy basic procedures in spot for contacting IBM advocate in the event of a earnest DB2 issue.
If you're having a earnest production problem and you exigency IBM's assistance, every minute is vital. That is not the time to exist scrabbling around to try to dig out customer numbers and URLs for the IBM advocate Portal. They occupy even seen situations where the IBM advocate site is blocked by the organisation's web browsing policy!
IBM is generally cheerful for you to open "test" PMRs to prove that the process works and ensure you can contact them quickly and efficiently if the exigency arises. Finally, don't forget that it's practicable for your IBM commerce confederate to open and manage your PMRs for you — they result this for many of their customers as a matter of course.
I hope you'll exist able to learn something from at least some of these scenarios, and buy steps to avoid similar situations happening in your environment.
