Clarity app fails to start with Unrecognized VM option

Products

• Clarity PPM SaaS
• Clarity PPM On Premise

Issue/Introduction

Trying to start Clarity app or bg, an error is thrown in app-system or bg-system.log:
 
Unrecognized VM option 'PrintGCTimeStamps'
Unrecognized VM option 'PrintHeapAtGC'
Unrecognized VM option 'UseParallelOldGC'
Unrecognized VM option 'PermSize=512m'

Cause

This is caused by outdated JVM parameters.
If you recently upgraded Java to a higher version, some of the options will no longer be the same, this is expected.

The JVM Parameters you are using for Clarity are customizable. If Java parameters are deprecated in this higher Java version and you have not updated them, this message will be thrown

Resolution

1. On Clarity server, open properties.xml, or CSA
2. Remove the old JVM parameter that is referenced in the log from the Application server or Background server Java VM parameters
3. Save and restart the services
4. Repeat for all servers in the cluster
