Synchronize nodes using wsdmin.sh

We can propagate node changes and wsadmin.sh.

There are two ways to complete this task. This topic uses the AdminControl object to synchronize nodes. Alternatively, we can use the node administration scripts in the AdminNodeManagement script library to synchronize a specific node, or to synchronize all active nodes.

A node synchronization is necessary in order to propagate configuration changes to the affected node or nodes. By default, this situation occurs periodically, as long as the node can communicate with the deployment manager. We can propagate changes explicitly by running commands that synchronize the configuration.

1. Set the variable for node synchronization.

   • Jacl:

     set Sync1 [$AdminControl completeObjectName type=NodeSync,process=nodeagent,node=myNodeName,*]

   • Jython:

     Sync1 = AdminControl.completeObjectName('type=NodeSync,process=nodeagent,node=myNodeName,*')

   Attribute	Definition
   set	is a Jacl command
   Sync1	is a variable name
   $	is a Jacl operator for substituting a variable name with its value
   AdminControl	is an object that enables the manipulation of MBeans running in a product process
   completeObjectName	is an AdminControl command
   type=NodeSync,process=nodeagent,node=myNodeName	is a fragment of the object name. The complete name is returned by this command. This fragment is used to find the matching object name which is the SyncNode object for the myNodeName node, where myNodeName is the name of the node that you use to synchronize configuration changes. For example: type=Server, name=serv1. It can be any valid combination of domain and key properties. For example, type, name, cell, node, process, and so on.

   Example output:

   WebSphere:platform=common,cell=myNetwork,version=5.0,name=node
   Sync,mbeanIdentifier=nodeSync,type=NodeSync,process=nodeagent,node=myBaseNode, process=nodeagent

2. Synchronize the node by issuing the following command:

   • Jacl:

     $AdminControl invoke $Sync1 sync

   • Jython:

     AdminControl.invoke(Sync1, 'sync')

   Attribute	Definition
   $	is a Jacl operator for substituting a variable name with its value
   AdminControl	is an object that enables the manipulation of MBeans that run in a product process
   invoke	is an AdminControl command
   Sync1	evaluates the ID of the server specified in step number 1
   sync	is an attribute of modify command

   Example output:

   true

   You receive an output value of true, if the synchronization completes.

Results

When the synchronization is complete, the files created in the config directory for the deployment manager now exist on the myNodeName node in the app_server_root/config directory.
