Incompatible state when starting up a WebLogic managed server

Problem:

After starting up the Oracle WebLogic 11g AdminServer server, you may get the following error when trying to start up any of your managed servers:

For server soa_server1, the Node Manager associated with machine LocalMachine is not reachable.
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.

Solution:

This is simply due to the Node Manager not running.

1. Start up the Node Manager as follows:

export MW_HOME=/u01/app/oracle/middlware
cd $MW_HOME/wlserver_10.3/server/bin
nohup $MW_HOME/wlserver_10.3/server/bin/startNodeManager.sh &

Applicable Versions:
