PSA behavior after the collection shutdown.

Products

• Subsystem Analyzer for DB2 for z/OS

Issue/Introduction

Does Subsystem Analyzer collection completely shut down all activities and processes related to SSA after a STOP(SSA) is issued?

Is there any activity remaining and consuming CPU/ZIIP? 

 

Environment

Release : 20.0

Component : CA Subsystem Analyzer for Db2 for z/OS

Resolution

The primary Subsystem Analyzer modules PSACIDC1 or PSACIDC2 will stay in the ECSA after the shutdown of Subsystem Analyzer, and will stay there awaiting reactivation.  This is done to ensure that no in-flight abends occur when Subsystem Analyzer is shutting down. These modules are not active or intrusive.
