Enable use of DSN_PROFILE* tables global variables for local workload

At the following link, we see global variables can be used with profile tables. https://www.ibm.com/docs/en/db2-for-zos/12?topic=connections-setting-built-in-global-variables-profile-tables However, there is a sentence that mentions the following:...

Enable zEDC for Tempdatasets

Actually no temporary Datasets are zEDC eligible, i suppose because there is no long term benefit in space reduction. Especially DB2 with LISTDEF (for example Reorg Tablespace LIST with SORTDEVT specification of very large Tablespaces) would benef...

RID problem instrumentation improvement

The IFI 2 & 3 fields QISTRLLM and QISTRPLM and the RID fields in the 316 and 401 are all basically “useless” these days to actually detect a RID related limit problem. I know that the QXRFMIAP is available in the IFI 2 & 3 but it is needed...

The ability to apply the DB2 Connect Unlimited Licence directly on zOS

issue DISPLAY BLOCKERS instead of DISPLAY CLAIMERS when DRAIN timeout

Currently when DRAIN fails during REORG, a DISPLAY CLAIMERS is issued. The draw back is there is no "age" information, so user does not know which thread is the blocker, because the claimer could also be waiter.

Add support for CREATE OR REPLACE VIEW syntax

I've seen that Db2 LUW and other types of databases support the syntax to do CREATE OR REPLACE VIEW. This can be useful as you don't have to have a separate statement to drop a view before rerunning a create statement. I had a new DB2 DBA on our t...

Delete DB2 Old Archive logs without stopping DB2

We have a lot of old logs in our DB2 BSDS that no longer exist. I dont find a documentation that explain how to remove them without stopping DB2 and in the DB2 doc : https://www.ibm.com/docs/en/db2-for-zos/12?topic=utilities-dsnju003-change-log-in...

Improve performance of EXPLAIN

With early versions of DB2 the performance of EXPLAIN was not relevant. Nowadays, where DBAs do thousands of EXPLAINs, the performance and turnaround is getting critical. I think there is room for better performance and throughput of mass EXPLAINs...
