What is the second factor used to calculate Sysview Performance Management Option for Db2 for z/OS (IDB2) exception:
Type: CPU percentage for a DB2 address space
V1: CPU used by DIST address space QWSAEJST
V2: N/A ?
The second factor does not apply for this exception but here is the breakdown of this exception:
The JS-TIMER and SRB-TIMER
Those values come from the STATS1 record, IFCID 1, from the DSNDQWSA section which is the DSECT for this section.
There are normally at least 4 repeating sections in the record, one for MSTR, one for DBM1, one for IRLM and one for DIST DB2 address spaces.
The JS-TIMER is the same as the DSECT field QWSAEJST, which is the job step timer value for the address space.
SRB-TIMER is the same as field QWSASRBT in this data section and contains the SRB timer value for the address space.
CPU used by MSTR address space QWSAEJST MSTR-JS-TIMER
CPU used by DBM1 address space QWSAEJST DBM1-JS-TIMER
CPU used by DIST address space QWSAEJST DIST-JS-TIMER
CPU used by IRLM address space QWSAEJST IRLM-JS-TIMER
