Reloading the CEI event service configuration manually

When you deploy or remove a monitor model application, changes are made to the Common Event Infrastructure (CEI) event service configuration that require the CEI event service to be stopped, notified of the new configuration, and restarted. IBM® Business Monitor attempts to perform these steps automatically, but if you have disabled the Synchronize changes with Nodes option in the administrative console preferences, IBM Business Monitor cannot automatically reload the CEI event service configuration when you deploy or remove a monitor model application.

1. Synchronize the configuration across all nodes. You can perform this synchronization from within the administrative console, or you can use the following wsadmin script:

   # synchronize the configuration across all the running nodes in the cell
   nodeSyncBeanNames = AdminControl.queryNames('type=NodeSync,*').split()
   for nodeSyncBeanName in nodeSyncBeanNames:
   	AdminControl.invoke(nodeSyncBeanName, 'sync')

2. Stop the CEI event service application. Because the application is hidden, you must use a wsadmin script. To stop the CEI event service on a server, run the following script:

   serverName = 'xxxx'
   nodeName = 'yyyy'
   applicationName = 'EventService'
   applicationManager = AdminControl.queryNames('type=ApplicationManager,node=%s,process=%s,*' % (nodeName, serverName))
   AdminControl.invoke(applicationManager, 'stopApplication', '[%s]' % applicationName, '[java.lang.String]')

   To stop the CEI event service on a cluster, run the following script:

   clusterName = 'zzzz'
   applicationName = 'EventService'
   
   # get list of cluster members
   clusterMembers = AdminConfig.getid('/ServerCluster:%s/ClusterMember:/' % clusterName).splitlines()
   
   # stop application in each cluster member
   for clusterMember in clusterMembers:
   
     # cluster member server name and node name
     serverName = AdminConfig.showAttribute(clusterMember, "memberName")
     nodeName = AdminConfig.showAttribute(clusterMember, "nodeName")
   
     # get ApplicationManager MBean for the cluster member
     applicationManager = AdminControl.queryNames('type=ApplicationManager,node=%s,process=%s,*' % (nodeName, serverName))
   
     # if the ApplicationManager MBean was found (for example, cluster member is running), stop the application
     if(len(applicationManager) > 0):
       AdminControl.invoke(applicationManager, 'stopApplication', '[%s]' % applicationName, '[java.lang.String]')

3. Invoke the reloadResources method on the ConfigUtil MBean on the target server (or list of cluster members) of the CEI event service. To reload the resources on a server, run the following script:

   serverName = 'xxxx'
   nodeName = 'yyyy'
   configUtil = AdminControl.queryNames('type=ConfigUtil,node=%s,process=%s,*' % (nodeName, serverName))
   AdminControl.invoke(configUtil, 'reloadResources', '[]', '[]')

   To reload the resources on a cluster, run the following script:

   clusterName = 'zzzz'
   
   # get list of cluster members
   clusterMembers = AdminConfig.getid('/ServerCluster:%s/ClusterMember:/' % clusterName).splitlines()
   
   # stop application in each cluster member
   for clusterMember in clusterMembers:
   
     # cluster member server name and node name
     serverName = AdminConfig.showAttribute(clusterMember, "memberName")
     nodeName = AdminConfig.showAttribute(clusterMember, "nodeName")
   
     # get ConfigUtil MBean for the cluster member
     configUtil = AdminControl.queryNames('type=ConfigUtil,node=%s,process=%s,*' % (nodeName, serverName))
   
     # if the ConfigUtil MBean was found (for example, cluster member is running), stop the application
     if(len(configUtil) > 0):
       AdminControl.invoke(configUtil, 'reloadResources', '[]', '[]')

4. Start the CEI event service application. Because the application is hidden, you must use a wsadmin script. To start the CEI event service on a server, run the following script:

   serverName = 'xxxx'
   nodeName = 'yyyy'
   applicationName = 'EventService'
   applicationManager = AdminControl.queryNames('type=ApplicationManager,node=%s,process=%s,*' % (nodeName, serverName))
   AdminControl.invoke(applicationManager, 'startApplication', '[%s]' % applicationName, '[java.lang.String]')

   To start the CEI event service on a cluster, run the following script:

   clusterName = 'zzzz'
   applicationName = 'EventService'
   
   # get list of cluster members
   clusterMembers = AdminConfig.getid('/ServerCluster:%s/ClusterMember:/' % clusterName).splitlines()
   
   # stop application in each cluster member
   for clusterMember in clusterMembers:
   
     # cluster member server name and node name
     serverName = AdminConfig.showAttribute(clusterMember, "memberName")
     nodeName = AdminConfig.showAttribute(clusterMember, "nodeName")
   
     # get ApplicationManager MBean for the cluster member
     applicationManager = AdminControl.queryNames('type=ApplicationManager,node=%s,process=%s,*' % (nodeName, serverName))
   
     # if the ApplicationManager MBean was found (for example, cluster member is running), stop the application
     if(len(applicationManager) > 0):
       AdminControl.invoke(applicationManager, 'startApplication', '[%s]' % applicationName, '[java.lang.String]')
