SYSVIEW Performance Management Option for DB2 for z/OS

Issue/Introduction

Site attempting to fallback from Sysview Performance Management for Db2 for z/OS (IDB2) r19 to r18 and the data collector failed with the following errors:

Resolution

Once you upgrade IDB2 from a lower to the higher release and you take with you the history files of the lower release
and start writing to them in the higher release, you cannot use them if you fallback to the lower level again.

If you try to use them again with the lower level data collector, you will get the following error:

DBG21023E 16:07:47 HISTORY: FILE HSTSTATS INVALID HISTORY FILE 
DBG36017E 16:07:47 OPEN FAILED FOR DDNAME HSTSTATS 

 

The best option will be to create a new r18 files if you want to fall back.
