Consider the following scenario, in a DB2 HADR configuration using ASYNC mode. Presently,the log files were extracted from TSM to a local file system on the standby server. Standby database was deactivated and re-activated causing the standby to go into LocalCatchUp state. However, its unable to read the local log file because its considered as a "stale" file and the standby re-enters a RemoteCatchUp state. This process was repeated two to three times and the standby fails to read the log file and switch HADR to RemoteCatchUp... [More]

One scenario you may have !!
You attend a monthly DB operation meeting.
Each DB administrator team from Oracle, DB2 and Sybase presents monthly events and various monitoring results.
On first turn, an Oracle guy indicates a performance issue on a specific day and says an SQL has triggered the issue.
And.......he shows the historical performance data for the SQL by keeping on track of the change day by day.
Actually the hash key value ' SQL_ID ' of Oracle enables this kind of analysis.
When performing a DB2 fixpack upgrade (rolling upgrade), for example from DB2 V9.7 FP8 to DB2 V9.7 FP9, in an HADR environment where HADR_SYNCMODE is set to SUPERASYNC as shown below :
HADR database role = PRIMARY
HADR local host... [More]
I-Spy returns an authentication error 951 when a user opens a database.
$ dbaccess sysmaster -
746: I-Spy: SQLERR -951 connecting to shadow server
These are some possible solutions for the 951 error:
Set INFORMIXSERVER to the shadowserver (database server name) in order to bypass I-Spy. If you are still seeing the 951 error, search other documents specific to the Informix server that addresses the 951 error.
Check if the... [More]
I am happy because I am going to get one more second to work on my PMRs! How? Leap Second!
So what is a leap second?
This is a definition from Wikipedia :
A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time. Without such a correction, time reckoned by Earth's rotation drifts away from atomic time because of irregularities in the Earth's rate of rotation. Since this system of... [More]

I am sharing one small script to monitor the changes in HADR state. If you know better way to monitor it, please share it in comments section. Thank you!
# Monitor the change in HADR state
# How it works?
# This is a cron job that needs to be set at OS level as DB2 instance user.
# It needs to be run for every 10 minutes... [More]
We often deal with PMRs on "SQL0805N Package not found" error and get questions about DB2 Packages from customers.
We do have lot of technotes and white papers on DB2 packages. I just wanted to consolidate all the information and give you a quick overview of DB2 CLI packages and help you to solve SQL0805N errors.
Packages : Packages in DB2 are control-structure database objects that contain executable forms of SQL statements or placement holders for executable forms or access plans.

Have you ever wondered why during a DB2 fixpack upgrade on a DPF environment, db2iupdt fails with DBI1167E "DPF instance cannot be updated from non instance owning nodes."?
Beginning in DB2 V9.5, fixpack upgrade was enhanced on Unix and Linux platforms to only run db2iupdt on instance owning node. Prior to DB2 V9.5, db2iupdat didn't do a hostname check. This was first introduced in DB2 V9.5. This check was done to ensure that the instance update only happens on the node defined on the first line of db2nodes.cfg for DPF... [More]
