In WebLogic 12c Managed Server Does Not Start with error The server xxxx is in an incompatible state

Error:

Trying to start managed server using the node manager showing following error:

"The server xxxx is in an incompatible state"

Solution:

Check that the instance is not running using ps -ef. If it is, use kill -9 <pid> to stop the running instance.

Remove the state file:

If the managed server name is “Server-Name” oacore_server1, then go to the managed server machine, delete the following:

$DOMAIN_HOME/servers/<Server-Name>/data/nodemanage/<Server-Name>.state

<Server-Name>.state is the node manager file containing instance information and status.

After deleting this file, the managed server can be remotely started from the Admin Console.
