Weblogic server 12.2.1.3 Java Agent not starting

Erik_Berglind — Wed, 26 Feb 2020 12:52:12 GMT

Hi,

We updated our application to Weblogic server 12.2.1.3 from 12.1.2 and after that Appdyanmics Java agent won't start.

Nothing is written in the log files and javaagent is set i weblogic startup agreement correclty "-javaagent:<path>/javaagent.jar".

We have updated javaagent to 4.5.19.29348 but still the same issue.

Anybody that have been out for the same issue and how did you solve it?

Machineagent is working fine so connection to controller is also working.

That is odd.

Can you post your JVM command line from ps -ef?

Do you see any output from the agent written into the console window of the JVM as it starts?

No I have no output from the Agent when JVM starts.

I'm running windows but this is my JVM command line:

Is there any solution to this? We are encountering the similar issue.

Everything looks fine, we used latest agent now but not reporting / not generating the logs as well.
