Db2 profiles - Enable monitoring and enforcement of AUTHIDs
Db2 v13 offers new feature of Db2 profiles to support monitoring and enforcement of TLS secure connections. Please add ability to do this at AUTHID level. Some apps and users have converted and we could put in a profile to ensure only secure conne...
Resolve issue where DB2 has an issue with invalid MDSNxx Class profiles created in RACF
IBM Please read the case TS013914362. In summary DB2 created dumps/abends when the RACF administrator deleted permissions to some incorrectly formatted profiles in one of the MDSNxx classes. When the administrator performed the permit delete and i...
Supply RACF Exit IRREVX01 to fail commands against Db2 classes that don't have the proper syntax.
As encountered in Case TS013914362, invalid profiles would not be created that could leave unused records in the RACF data base and also confuse Db2 when RACF notifies Db2 to refresh the cached profiles. All Db2 for z/OS users utilizing RACF could...
Currently IBM allows the creation of indexes for JSON docs stored in an inline LOB but not a non-inline LOB. We want to make full use of JSON docs in DB2 for zOS. We wanted to avoid having to move more apps to MongoDB.
Set Partition Index, DPSI to the same DSSIZE as Tablespace when converting to RPN and ALTER TABLESPACE DSSIZE is after ALTER TABLESPACE PAGENUM RELATIVE
In numerous cases it is impossible to put the ALTER TABLESPACE DSSIZE in front of the ALTER TABLESPACE PAGENUM RELATIVE due to the number of partitions and page size. Currently this only works with the following. After the reorg materialization th...
Having to force the business to accept service outages to bring application DB2 packages and plans up to the current operating software level has been a painful aspect of DB2 upgrades for many years.
This also meant that the adoption/rollout of s...
DB2: Enhancing DB2 decision making during starting up in DEFER ALL mode
We would like to enhance the DB2 product when starting a database with the "defer all" zparm parameter. It is unfortunate that there is a limit of 2500 in place, and it is also unfortunate that the trusted context is not automatically built, even ...
Meter "dirty" pages written to DB2 table spaces (disk) from CF or local buffer pools
DB2 uses 300 tasks (DB2 writers - it could be more now with later DB2 releases) to write modified (aka, "dirty") pages to the DB2 table spaces (either permanent tables or DB2 work files). From a DB2 perspective this is "efficient" but from a resou...
The -DISPLAY TRACE(*) command does not indicate which address space owns the trace when the destination is OPx. Since the OPx destination must be managed by some product/address space it would be helpful to know this. A typical scenario: The syspr...
We have some large tables that need to be updated from time to time. Each time a partition is rotated it is reset, so I think that could allow the table/tablespace change to be materialize. This would allow use to save the time and processing cost...
