Restarting node agent processes using the wsadmin scripting tool

If you stop a node agent process, you cannot start the process using the wsadmin tool or the administrative console. Use this topic to restart a running node agent.

1. Start the wsadmin scripting tool.
2. Determine the name of the node agent to restart.
   • Using Jacl:

     set na [$AdminControl queryNames type=NodeAgent,node=mynode,*]

   • Using Jython:

     na = AdminControl.queryNames('type=NodeAgent,node=mynode,*')

3. Determine the NodeAgent MBean operation.
   Use the following help commands to return information about the restart option:

   • Using Jacl:

     $Help operations $na

   • Using Jython:

     print Help.operations(na)

4. Restart the node agent process.
   As the help output from the operations command displays, you must specify two boolean parameters in the command invocation. First, specify true for the syncFirst parameter to synchronize your configuration before the command restarts the node. Next, specify true for the restartServers parameter to restart all running servers while the command restarts the node. The following command example synchronizes and restarts the application servers that are running on the node when the node agent restarts:

   • Using Jacl:

     $AdminControl invoke $na restart "true true"

   • Using Jython:

     AdminControl.invoke(na,'restart','true true')
