The server managed Server is in an incompatible state

The server managed Server is in an incompatible state

 

Observation: While trying to restart the managed server, the console displays following error message

“All of the servers selected are currently in a state which is incompatible with this operation or are not associated with a running Node Manager or you are not authorized to perform the action requested. No action will be performed.”

Causes:

1)     Most Common : Nodemanager is not running

2)     Not so Common: The “<managedserver>.state” file, present in MS/data/nodemanager directory, has incorrect entry

In My case it was:

[oracle@xxxxxxx nodemanager]$ cat dv_batch_server3.state

FAILED_NOT_RESTARTABLE:N:N

/opt/oracle/domains/sit_domain/servers/dv_batch_server3/data/nodemanager/ [oracle@lzbvmidsit1 nodemanager]$ cat dv_batch_server3.state FAILED_NOT_RESTARTABLE:N:N

 

Resolution:

1)     Restart the nodemanager

2)     Remove the file <MS>/data/nodemanager/<MS>.state
