Issue/Introduction

During the initialization of the CA Sysview address spaces there are these SYSVIEW1 thru 9 STCs created, what are these?

Cause

New JVM component introduction

Environment

Release : 15.0

Component : SYSVIEW

Resolution

For the CA Sysview stc's, CA Sysview will run a job to detect the JAVA version for each active JVM in the system.
The jobs should run quickly unless your USS environment is running slow or encountering problems.
The jobs are simply issuing commands to obtain the version and some other that is sent back to SYSVIEW where it gets cached.

Should these stc's take a long time to finish, the advice is to check if there are delays in the USS environment by logging on to OMVS and issuing command 'JAVA -version' and see how long it takes to come back.
It's also possible to issue the SYSVIEW command JVMVERS and use one of the ResolvedHome address in the USS environment and issue 'address JAVA -version' for one of those to see how long it takes.
Eventually the address spaces spawned should go away unless there is a problem.

Restarting SYSVIEW when the rest of the system is up will cause many jobs to be spawned since SYSVIEW has to detect all active JVM's at startup.


Additional Information

Check if solution SO08342 is applied.. This would reduce the amount of spawned stc's, but it wont eliminate them completely...
