The issue “
To resolve this issue, the cluster debug flags need to be enabled consistently: either disabled on all the servers of the cluster or enabled on all of them. In a production environment, debugging should be disabled. Cluster debug flags should be enabled only while debugging a problem with the Unicast cluster.
Solution via AdminServer:
- Click on Domain Structure and select your Server
- Select debugging tab
- Select items, that you want to disable or/enable, e.g. Disable weblogic debugging by click on „disable“(german: „deaktivieren“)
- Check Log files, wether the issue is solved.
