Omegamon needs to enhance to support Db2 APAR:PI78979

Db2 APAR:PI78979 provides an ability to confirm how much discarded pages is in REAL PAGE with KEEP(YES).

Current OMEGAMON XE FOR DB2 PERFORMANCE Expert V5.4 does not support PI7897 and is not able to show the following new field .

The fields are ;

QW0225DPGS EQU X'10000000' ! This record used Discardpages(YES)


- QW0225ShrStkstg_dpage

- QW0225PriStg_dpage

- QW0225ShrStg_dpage

- QW0225ComStg_dpage

We have confirmed that the IFCID225's RECTRACE does not have these information.

Customer wants to check these outputs soon because CS usage of Db2 is one of their highest checking (include tuning) factor especially during migration period..

We have an information that Db2 V12 will have a 30 % increase in real storage,so it is dangerous if we don't know db2's real storage usage more accurately than usual.

I.E we have to pay very high attention about monitoring the real storage usage.we have to be very careful about monitoring the real storage usage.

Who would benefit from this IDEA? As a customer,I can monitor accurate value of discard pages which help me to estimate real storage usage
How should it work?

Omegamon should support new IFCID225 .

At moment,We have to check manually those values by printing SMF.

We don't think this is an alternative.

We want to enhance Omegamon to be able to see the record via REC trace at least.

Idea Priority High
Priority Justification We want to this enhancement before our migration to Db2 V12 on September.
