When I try to launch an updated Tom cat agent 10.7, I'm getting this Exception:
"java.lang.UnsupportedClassVersionError" implies a Java versioning compatibility problem e.g. this KB for JRE 1.6
Agent running an unsupported Java release produces - CA Knowledge
According to our Product Compatibility Matrix no version of Tomcat is officially supported with an IBM (J9) JVM . Tomcat versions 6.x, 7.x, 8.x, 9.x are supported for Oracle JRE 1.7 & 1.8 only:
However the 10.7 documentation has been updated to advise that with any IBM (J9) JVM the AgentNoRedefNoRetrans.jar and a modified profile should be used. Here is the relevant page for Apache with IBM J9: Apache Tomcat - CA Application Performance Management - 10.7 - CA Technologies Documentation
So if you are currently using the Agent.jar please try above steps instead.
(This KB covers a similar topic: When running an IBM JVM, the APM documentation rec - CA Knowledge)
If you still have no success the best plan would be to create a support case so we can diagnose in more detail.
Hope that helps.
Thanks for your help Lynn :-) I'm just wondering whether I should change catalina.sh startup script or the instance.conf file with that options. Is the same? The both files are called on startup?
I am not familiar with instance.conf but maybe it is related to some multi-instance configuration of Tomcat under the same installation?
For a standard Tomcat installation the catalina.sh script is normally the place to modify java startup options to include the agent properties.
The Tibo iProcess documentation I found here also refers to catalina.sh when modifying java properties:
So I would use that.
