Making the real-time stats externalization optional

The Automation Tool issues the ACCESS DATABASE(*) SPACE(*) MODE(STATS) command whenever the REALTIMESTATS option is used in an exception profile. This default behavior causes some problems:

  • Since the ACCESS command is issued to every DB and TS in the system, it can conflict with other processes. In our case, we observed deadlocks between the ACCESS commands and REORGs creating implicit mapping tables.

  • Customers can run multiple generation jobs in parallel which means the ACCESS command can be issued more than once simultaneously.

Could you consider an enhancement of making the real-time stats externalization optional? Customers should be able to decide whether they need to externalize the real-time stats thus issue the ACCESS command or they want to rely on the STATSINT zparm value in their systems and no need to issue the ACCESS command.
