Specifying running objects using the wsadmin tool

 

Procedure

  1. Start wsadmin

  2. Obtain the configuration ID with one of the following ways:

    • Obtain the object name with the completeObjectName command, for example:

      where:

      set is a Jacl command
      var 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 server process
      completeObjectName is an AdminControl command
      template is a string containing a segment of the object name to be matched. The template has the same format as an object name with the following pattern: [domainName]:property=value[,property=value]*. See Object name, Attribute, Attribute list for more information.

      If there are several MBeans that match the template, the completeObjectName command only retuns the first match. The matching MBean object name is then assigned to a variable.

      To look for server1 MBean in mynode, use the following example:

      • Jacl

        set server1 [$AdminControl completeObjectName node=mynode,type=Server,name=server1,*]
        

      • Jython

        server1 = AdminControl.completeObjectName('node=mynode,type=Server,name=server1,*')
        

    • Obtain the object name with the queryNames command, for example:

      where:

      set is a Jacl command
      var 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.
      queryNames is an AdminControl command
      template is a string containing a segment of the object name to be matched. The template has the same format as an object name with the following pattern: [domainName]:property=value[,property=value]*

  3. If there are more than one running objects returned from the queryNames command, the objects are returned in a list syntax. One simple way to retrieve a single element from the list is to use the lindex command in Jacl and split command in Jython. The following example retrieves the first running object from the server list:

    • Jacl

      set allServers [$AdminControl queryNames type=Server,*]
      set aServer [lindex $allServers 0]
      

    • Jython

      allServers = AdminControl.queryNames('type=Server,*')
      
      # get line separator 
      import  java
      lineSeparator = java.lang.System.getProperty('line.separator')
      
      aServer = allServers.split(lineSeparator)[0]
      

    For other ways to manipulate the list and then perform pattern matching to look for a specified configuration object, refer to the Jacl syntax.

 

Result

You can now use the running object in with other AdminControl commands that require an object name as a parameter.
