Question

Hi My current environment is Weblogic 12c Std i have 2 servers which is running one Admin server 2 managed servers Node -1 contains admin & 1 managed servers Node -2 contains Managed servers

My issues is i am able to stop node-2 managed server node 2 from Admin console but not able to start from Admin console

While start i am getting below Error on Console

Message icon - Warning For server mrm_node2, the Node Manager associated with machine mrm_machine2 is not reachable. Message icon - Warning 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.

In Adminserver log i am getting below warning

<[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <> <> <1505972472314>

<[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <> <> <1505972472314> <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <> <> <1505972472314> <[ACTIVE] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'> <> <> <> <1505972472315>

To be able to start a Managed Server via the Admin Server, the Node Manager needs to be running and obviously be reachable.

You can start the Node Manager with the startNodeManager.sh script in <weblogic-home>/server/bin.

If the Managed Server is already running you can shut it down through the Admin Server even without the Node Manager, because then the Managed Server is already in communication with the Admin Server.
