TrueSight Capacity Optimization
TSCO 11.x, 10.x
Typically, TSCO does not support allowing TSCO administrators to upgrade Java version used by TSCO. As a practice, the product updates the Java version in every major release (and possibly in a Service Pack, Feature Pack, or Fix Pack) and the update is usually aligned with the latest Java security fixes.
Can I install or adopt latest OpenJDK version to replace the current JRE installed on my server?Yes, it is supported to replace the embedded Java release on the environment with latest openJDK release available. This can be done on Application Server(s) and ETL Engines(s) with no issues. For further details refer to the official TSCO documentation ( TSCO version > Release notes and notices > Support for Java) that covers this topic and the steps suggested to replace the existing JRE version with OpenDJK
Which TSCO component or required additional products include an embedded JVM for TSCO version 11.5?The Java component is a core required component in the TSCO Application Server and TSCO ETL Engine Server components which require java and wouldn't be able to operate without it. The Oracle Java has been replaced with OpenJDK on the TSCO Application Server and ETL Engine Servers.
The Java component is a core requirement for the TrueSight Presentation Server (TSPS) as well.
If you require to replace the current JRE with adoptopenjdk in TrueSight Presentation Server, please refer to the official documentation:
The Java component is a core requirement for the Remedy Single-Sign-On (RSSO) server which will be deployed during the product installation (when using the 'RSSO for TrueSight' installer) or can be deployed separately (when using the native RSSO product installer).
The TSCO Gateway Server is still installed using the java base InstallAnywhere installer and thus in version 11.5 you'll still find the BMCBPAInstallJVM directory but it has been updated to use OpenJDK.
The Java component has been removed from the TSCO Agent in version 11.5 (by replacing the TSCO Agent installer with a script based installation process) so you shouldn't see any Java deployment for the TSCO 11.5 agent anymore.
