Make IFI process zIIP eligible

With more and more data being replicated off host, the replication tasks are increasingly using more and more CPU to read the logs. Allowing the IFI read process to be zIIP eligible would help reduce our general purpose CPU consumption. This would...

Add DSNL523I or DSNL519I for all available PORTs

Currently at DB2 startup, or when DDF is started, a DSNL523I or DSNL519I message is issued for the main DB2 PORT, the main SECPORT, and RESORT. I would like the same to be done for all available LOCATION ALIAS PORTs so our automation can validate ...

Enable dropping tablespace partitions without changing to data capture none

With the ability to convert tablespaces from PBR to PBG and back, we are now able to drop partitions in both PBRs and PBGs. However, this requires that we switch off data capture on the table for the duration of the change.As we are using CDC to r...

Enhanced Instrumentation for workfiles

A possibility through IFI and/or a new command -DIS WORKFILES to get an “asis” use list of all work pools (Sort , DGTT, Work etc.) This data is crucial for tuning the number, size and type of the work spaces that we all have. The output should be ...

Enhance messages of CDDS start / stop in data sharing to document which member stopped / started CDDS

When CDDS is stopped / started (e.g. STOP CDDS) in a member of a data sharing group this member documents messages DSNJ375I and DSN9022I in MSTR. In the MSTR of the other members of the group only DSNJ375I is logged. For monitoring / problem manag...

Enhance DSNJU008 LIST CDDS output to also list the number of tablespaces maintained in the CDDS

DSNJU008 LIST CDDS today lists the number of dictionaries contained in the CDDS. Example: “DICTIONARY RECORDS PRINTED 123”. This could be 1 dictionary of 123 tablespaces, or 41 tablespaces with 3 dictionaries for each (41 * 3 = 123). We would like...
