Expand db2 autoconfig to identify configuration settings less than default value
Db2 autoconfig is one way to identify configuration settings that are less than the current default of the current release. Since in-place upgrades preserve the configuration settings from the previous release, DBAs must manually find and determin...
DB2_FMP_FODC variable needs to be extended to application traps
Failures in DB2 may result in Trap files, by default written to the directory where DIAGPATH is set, usually $HOME. To avoid disk-full conditions, this can be redirected with db2set variables DB2_FODC and DB2_FMP_FODC for most of the FODC traps. H...
Enhance automatic SORTHEAP management by fixing the defined base value as the minimum for STMM
As we had an issue with STMM reducing the SORTHEAP too much during lower load on the database, we would like to see the defined base value for the sortheap treated as the minimum value, that STMM would not reduce the sortheap below that value if t...
Enable DATABASE_MEMORY change on WRITE SUSPEND database
We are using db2relocatedb to deploy test, dev, preprod environments from production images (disc snapshots). This happens multiple times a week (talking about multiple hundred databases). Most databases have DATABASE_MEMORY set to AUTOMATIC. Relo...
Provide pre and post upgrade dbm and db checks of Db2 parameters and highlight any deltas
It is currently a best practice that we recommend customers do pre and post upgrade dbm and db checks manually. The request is that this should be performed automatically as part of the Db2 upgrade script itself.
Comparing before and after parame...

A DB cfg parameter to set the default tablespace to prevent objects ending up in the wrong TS
When not explicitly set in the CREATE TABLE statement, a newly created table will end up in the last created tablespace. A lot of customers have problems with this for several reasons. They have no control over table placement when using a framewo...
For our external Stored Procedures (written in Cobol, PL/1, C) we need 1. the flexibility of keepfenced=no to get changes in shared-objects active (i.e: in case of hotfixes) without a restart of db2.2. the speed of keepfenced=yes, because by the s...
Support converting non-restricted databases to restricted databases in Db2
There can be legacy databases created with non-restricted mode. However as security policies get stringent there is need to convert these databases into restricted databases. The way to convert currently is to recreate the database from scratch. I...
