Java Agent 4.2 compatibility with Weblogic 12.2.1.3

SOLVED

Java Agent 4.2 compatibility with Weblogic 12.2.1.3

We are standing up new environment where few our applicaitons are hosted on Weblogic 12.2.1.3, OS Redhat 7.4, JDK 1.8.0_131

Java agent (4.2.13.1) is not able to startup successfully. I dont see any errors on the server.out file or no log files on the agent log path. Macihne agent is able to run on the same platform without any issues.

Upon reviewing the compatability matrix I didnt see Weblogic 12.2 version as supported. Does anyone faced the same challenge?

Version 4.3.x of the agent was where we introduced support for java 8

 

You will need to use v4.3 or higher of the agent to instrument any java 8 JVM

 

Actually, I take that back; 4.2 did include java 8 support.  What happens when WebLogic fails to start?  Do you get any error output?

 

Please note, however, v4.2 of the product has now reached its end of life.

 

Warm regards,

Thanks for the reply, Now I understand the compatibility with 4.3 and JDK 8. Would the agent 4.3 compatible with WebLogic 12.2. I wanted to get confirmation before going the path of upgrade (would the agent upgrade need controller upgrade as well?).

 

Note: We do have some 4.2 version agents monitoring JDK 1.8 bootstrap applications

Application startup without any issues. weblogic and app are healthy.

I see the below error in the log. I have another bootstrap apps on the box which is working fine.

 

Could not resolve Agent installation directory, please restart with system property appagent.install.dir
