Synchronizing nodes with the wsadmin tool

You can propagate node changes using scripting and the wsadmin tool.

Overview

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. You can propagate changes explicitly by performing the following steps:

Procedure

Set the variable for node synchronization.

Using Jacl:

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

Using Jython:

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

where:

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 WebSphere Application Server process
completeObjectName is an AdminControl command
type=NodeSync,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,node=myBaseNode,
process=nodeagent

Synchronize the node by issuing the following command:

Using Jacl:

$AdminControl invoke $Sync1 sync

Using Jython:
```
AdminControl.invoke(Sync1, 'sync')
```

where:

$ 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 WebSphere Application Server process
invoke is an AdminControl command
Sync1 evaluates the ID of the server that is 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.
