Workspace Db2 for z/OS

Accurately Report DB2 Real Storage Usage in IFCID 225 When KEEPREAL=YES Is Used

We need additional information to be included in DB2 IFCID 225 (or corrections made to the existing fields) so that we can see the actual current real memory required for a DB2 member instance. This would be true even if the DB2 is running with PM99575 applied, RSM=AUTO as recommended, on an LPAR that is not paging also as recommended, such that DB2 does DSCARDS with KEEPREAL=YES which results in the existing real memory tracking fields being overstated, in some cases by 50%. We are thinking of the 225 top level fields such as qwa225rl, qwb225rl, QW0225SHRSTG_REAL, QW0225SHRSTKSTG_REAL, and qw0225comstg_real and all of the other sub fields that add up to the top level fields.
