Subsystem Analyzer for DB2 for z/OS

Issue/Introduction

Encountered a concern where spool storage space has reached critical threshold as the Xmanager (PTXMAN)
started task has triggered multiple dumps:

Environment

Release : 20.0
Component : CA Subsystem Analyzer for Db2 for z/OS

Resolution

The U0003 abend occurs while CA Subsystem Analyzer for Db2 for z/OS (PSA)
is attempting to externalize subsystem workload data.

While the Db2 object data is being externalized successfully, the subsystem workload data
is not being externalized successfully due to the U0003 abend.

Diagnosis suggests that the problem is being triggered by the physical characteristics of the PSA datastore.
Recommend allocating a new PSA datastore to resolve the abend scenario.
