Weblogic Server Auto Restart with Node Manager as Linux service

Sometimes servers need to reboot and then it's nice to have certain services to start automatically. Oracle Weblogic's Node Manager is one of them and in order to have Node Manager start automatically it must be configured as a daemon. Unfortunately Oracle doesn't provide init scripts to run it as a Linux service but it's pretty simple to create your own startup scripts. Just create a new nodemgr script under /etc/init.d/, add it as a service and you're done, as Oracle Fusion Middleware -blog writes.

For example on Red Hat Enterprise Linux Server 5.6 with Oracle Weblogic Server 10.3.5 the /etc/init.d/nodemgr looks like this (edit the script to reflect your Weblogic installation path):


#!/bin/sh
#
# nodemgr Oracle Weblogic NodeManager service
#
# chkconfig:   345 85 15
# description: Oracle Weblogic NodeManager service

            exit

}

        if [ "$OLDPID" != "" ]; then
            /bin/echo "$SERVICE_NAME is running (pid: $OLDPID)"
        else
            /bin/echo "$SERVICE_NAME is stopped"

        RETVAL=$?
        ;;
  *)
        echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}"
        exit 1
esac

exit $RETVAL

Add the Node Manager to start after server reboot:

# chmod +x /etc/init.d/nodemgr
# chkconfig --add nodemgr
# chkconfig --list
nodemgr         0:off   1:off   2:off   3:on    4:on    5:on    6:off

Also now the Node Manager can be controlled via the service command (e.g. service nodemgr restart).

When you have the Node Manager restarting automatically after a system reboot, you can also have Weblogic managed servers automatically restarted by Node Manager. Managed servers will be restarted only if they were running at the time the shutdown was issued. Just activate the Auto Restart option in the Administration Console (Environment > Servers > selected server > Health Monitoring) and you might also need to set the CrashRecoveryEnabled to "true" in $WL_HOME/wlserver_10.3/common/nodemanager/nodemanager.properties.

With little scripting and configuration your sysadmin tasks have now become a little easier.

I am using this script in RHEL Linux 5.6 with /etc/init.d path. when i reboot, the nodemanager is not starting automatically. kindly any one let me the solutions. i given every path correctly.

please assist me. Thanks in Advance...

The error is due to the wrong hostname set in Listen Address feild.

I have the same error. If I execute "service nodemgr start" or "service nodemgr restart" or "service nodemgr stop" the error is "SEVERE: Fatal error in node manager server java.net.UnknownHostException: start: Name or service not known". I have in my nodemanager.properties the option ListenAddress set. But I don't know why when the system tries to init the service, executes the option "service ... start" and aparently ignores the nodemanager.properties.... Any solution?

I tried to use your solution and I did install it as a service.
But on my tests trying to start, stop, restart and get the status with the command
service nodemgr start I get this
