On screen DBGSDISS(R/SYSSVCS) Thread Counts - 30 Seconds(DBGSDISS)(option 1, 6 & 6 from the IDB2 main menu) the following is displayed:
HWM CTHREAD Threads 266 53
HWM IDBACK Threads 300 99
HWM IDFORE Threads 6 0
HWM MAXDBAT Threads 176 53
and the IDBACK count is HWM and doesn't change until bouncing DB2
How to view the current active IDBACK count ? is that value displayed somewhere in IDB2?
Release : 20.0
Component : SYSVIEW Performance Management Option for DB2 for z/OS
According to IBM, current IDBACK cannot be retrieved.
