Starting WebCenter Content 11g on boot

Starting WebCenter Content 11g is a bit different from the startup of UCM 10g. With 11g, you can start only the managed server for the WebCenter Content instance or you can start the Admin Server with it, or you can start Node Manager, the Admin Server and the Managed Instance.

Starting Node Manager allows you to use the Admin Server to start and stop the WebCenter Content managed server from the browser. Starting Admin Server allows you to monitor the WebCenter Content managed server and to use.

Configuring to use Node Manager

To use Node Manager to start and stop WebCenter Content, you must first
  • Configure a machine
  • Add the Admin Server and Managed Server to the machine
  • Enable Node Manager to use the WebCenter Content startup scripts

Configure a machine

In WebLogic, a Machine is a logical representation of a physical server. The Admin Server uses the machine definition and the Node Manager to manage remote servers. During the initial configuration of WebCenter content there was the opportunity to configure machines. If you did this then you can skip this section. If not, then follow these steps to create a machine.
  1. If not started, then start the Admin Server. 
  2. Under Environment, select Machines.
     
  3. Select to create a new machine
     
  4. Give the machine a meaningful name and set the OS then select Next
     
  5. Complete the rest of the form and select Finish

Add the Admin Server and Managed Server to the machine

  1. Return to the home page and select Environment, Machines. 
  2. Select the name of the machine you just created
     
  3. Select the Servers tab
     
  4. Select to add a server
     
  5. Select the server to add
     
  6. Select Next. Repeat this to add all the servers needed.

Enable Node Manager to use the WebCenter Content startup scripts

The first step is to enable Node Manager to use the startup scripts. To do this, follow these steps:
  1. Log into your system as the user who installed WebCenter Content (oracle in my case)
  2. Navigate to the following directory
    MIDDLEWARE_HOME/oracle_common/common/bin
    MIDDLEWARE_HOME is the directory where Oracle Fusion Middleware is installed.
  3. Run the setNMProps.sh script to set the StartScriptEnabled property to true before starting Node Manager:
    ./setNMProps.sh
    This is a one-time action. After you run this script, you can skip this step before starting Node Manager again.
  4. Start Node Manager with the startNodeManager script.
    Linux script: WL_HOME/server/bin/startNodeManager.sh
    WL_HOME is the directory where Oracle WebLogic Server is installed.
  5. Stop the Node Manager and the Admin Server.

Set Node Manager to run as a startup service

The next step is to set the Node Manager to run as a service on startup. To do this, follow these steps:
  1. Log into Linux as root
  2. Create a new file in /etc/init.d named nodemanager containing the following:
    #!/bin/bash
    
    # nodemanager Oracle Weblogic NodeManager service
    #
    # chkconfig:   2345 85 15

  3. Edit the nodemanager file and verify the following
    •  # chkconfig:   2345 85 15
      this line tells chkconfig to set the run levels at 2345 (same as Oracle database) it also puts the start at priority 85 and the stop at priority 15 (database is 80 and 05)
    • export MW_HOME=/u01/app/oracle/Middleware/
    • export JAVA_HOME=/u01/app/oracle/jdk1.6.0_31
    • user='oracle'
    • save and exit
  4. make it executable
    [root@dev init.d]# chgmod 755 nodemanager
    [root@dev init.d]#
    
  5. add it to the services list
    [root@dev init.d]# chkconfig --add nodemanager
    [root@dev init.d]#
  6. check that it is there with
    [root@dev init.d]# chkconfig --list|grep nodemanager
    nodemanager     0:off   1:off   2:off   3:on    4:on    5:on    6:off
    [root@dev init.d]#
  7. Test the service
    [root@dev init.d]# 
    [root@dev init.d]#
    
    [root@dev init.d]# service nodemanager start
    Starting nodemanager: 
    :
    :
    INFO: Plain socket listener started on port 5556
    [root@dev init.d]#
    
    [root@dev init.d]# service nodemanager status
    nodemanager (pid:21241) is running...
    [root@dev init.d]#
    

Set domain servers  to run as a startup service

Now that Node Manager starts automatically, we need to get the Admin Server and Managed Servers running.
  1. Log into Linux as root
  2. Create a directory called nm_scripts in the Middleware home and place these files there
    • dev_env.sh
      export wlsAdminServer="AdminServer"

  4. Verify the data and settings in these files 
    • Edit the wlsservers file and verify the following
      # chkconfig:   2345 86 14
      this line tells chkconfig to set the run levels at 2345 (same as Oracle database)
      it also puts the start at priority 85 and the stop at priority 15 (database is 80 and 05)
      MW_HOME="/u01/app/oracle/Middleware"
      WL_HOME="${MW_HOME}/wlserver_10.3"
      DOMAIN_HOME="${MW_HOME}/user_projects/domains/lowes_domain"
      SCRIPT_HOME="${MW_HOME}/nm_scripts"
      export SCRIPT_HOME
      user='oracle'
      
    • save and exit
  5. make it executable
    [root@dev init.d]# chgmod 755 wlsservers
    [root@dev init.d]#
    
  6. Add it to the services list
    [root@dev init.d]# chkconfig --add wlsservers
    [root@dev init.d]#
    
  7. Check that it is there with
    [root@dev init.d]# chkconfig --list|grep wlsservers
    wlsservers 0:off   1:off   2:off   3:on    4:on    5:on    6:off
    [root@dev init.d]#
    
  8. Test the service
    [root@dev init.d]# service wlsservers start
    [root@dev init.d]#
    [root@dev init.d]# service wlsservers status
    [root@dev init.d]#
    [root@dev init.d]# service nodemanager stop
    [root@dev init.d]#
    

Reboot and verify

Reboot the system and verify that the service start.
