Updating the Java Version

The following procedure should be run on the web service and generation nodes of a single-node machine in order to update the Java version.

1. Check that nothing is returned on web service node and gen nodes:

   oarstat
   

2. Check that nothing is returned on gen nodes only:

   ps -ef | grep oar
   

3. On the web service node, check the log to ensure that everything is out:

   tailf /var/log/glassfish/domain_uforge/uforge-web-service.log
   

4. Stop the web service:

   service glassfish stop ;
   

5. Now that nothing can happen on the web service side, you can shut down other services.

   • On the UI node(s):

     service tomcat stop
     

   • On the LDAP node:

     service OpenDJ stop
     

6. Check if the processes are stopped. Usually this is run on the DB node for the cron update_repos_pkgs.sh:

   ps -ef | egrep -i 'java|spider'
   

7. Launch update.:

   yum update jdk
   

8. Restart the services.

   # service OpenDJ start
   # service glassfish start
   # service tomcat start
