During the EM 12.1.0.3.0 configuration to monitor GoldenGate, I stepped through the documentation (as I have numerous times in the past) but this time I kept getting the error message in the jagent.log.

java.lang.NullPointerException

From my previous experience with the JAgent, I’d had to make many quirky changes in the managers parameter file. For example:

1. Rename the parameter file from MGR.prm to mgr.prm
2. Remove any comments from the managers parameter file that contain the word “port”
3. Remove all comments from the parameter file!

None of those tricks worked because I kept getting the same error message. After the correct search on MOS yielded “OGG 12c JAGENT Fails To Initialize MBeansContainerImpl – Runtime Exception Starting JAgent Server (Doc ID 1598597.1)” suggesting that I add the line below in the Config.properties. 

jagent.ssl=false

Due to the default behavior change in GoldenGate 12c (which is not stated), it is recommended that we add the line above for EM12c monitor configuration. Sure enough, once it was added the JAgent started successfully.

Hope this was helpful.

Cheers!
