Configure new J2C activation specifications using scripting

 

You can configure new J2C activation specifications using scripting and the wsadmin tool. Before starting this task, the wsadmin tool must be running. See the Start the wsadmin scripting client article for more information.

 

Overview

Perform the following steps to configure a J2C activation specifications:

 

Procedure

1. Identify the parent ID and assign it to the newra variable.

   Use Jacl:

   set newra [$AdminConfig getid /Cell:mycell/Node:mynode/J2CResourceAdapter:RAR1/]
   

   • Use Jython:

     newra = AdminConfig.getid('/Cell:mycell/Node:mynode/J2CResourceAdapter:RAR1/') print newra
     

   Example output:

   RAR1(cells/mycell/nodes/mynode|resources.xml#J2CResourceAdapter_1)
   

2. There are two ways to configure a new J2C administrative object. Perform one of the following:

   • Use the AdminTask object:

     1. List the administrative object interfaces:Using Jacl:

        $AdminTask listMessageListenerTypes $newra
        

        Using Jython:

        AdminTask.listMessageListenerTypes(newra)
        

        Example output:

        javax.jms.MessageListener
        

     2. Create a J2C administrative object:Using Jacl:

        $AdminTask createJ2CActivationSpec $newra { -name ac1 
        -jndiName eis/ac1 -message ListenerType  javax.jms.MessageListener}
        
        

        Use Jython:

        AdminTask.createJ2CActivationSpec(newra, ['-name', 'ao1', 
        '-jndiName', 'eis/ao1', '-message', 'ListenerType', 
        'javax.jms.MessageListener'])
        

   • Use the AdminConfig object:

     1. Use Jacl:

        $AdminConfig required J2CActivationSpec
        

        Using Jython:

        print AdminConfig.required('J2CActivationSpec')
        

        Example output:

        Attribute Type activationSpec ActivationSpec@
        

     2. If your resource adapter is JCA V1.5 and you have multiple activation specifications defined, it is required specified the activation specification attribute. If your resource adapter is JCA V1.5 and you have only one activation specification defined, it will be picked up automatically. If your resource adapter is JCA V1.0, you do not need to specify the activationSpec attribute. Perform the following command to list the activation specifications defined by the resource adapter:Using Jacl:

        $AdminConfig list ActivationSpec $newra
        

        Using Jython:

        print AdminConfig.list('ActivationSpec', $newra)
        

     3. Set the administrative object that a variable:Using Jacl:

        set ac ActivationSpecID set name [list name J2CAC1] set jname [jndiName eis/j2cac1] set j2cacAttrs [list $name $jname]
        

        Use Jython:

        ac = ActivationSpecID  name = ['name', 'J2CAC1'] jname = ['jndiName', 'eis/j2cac1'] j2cacAttrs = [name, jname]
        

     4. If you are specifying the ActivationSpec attribute, also set up the following:Using Jacl:

        set cdcttr [list activationSpec $ac]
        

        Use Jython:

        cdattr = ['activationSpec', ac]
        

     5. Create a J2C activation specification object:Using Jacl:

        $AdminConfig create J2CActivationSpec $newra $j2cacAttrs
        

        Using Jython:

        print AdminConfig.create('J2CActivationSpec', newra,j2cacAttrs)
        

        Example output:

        J2CAC1(cells/mycell/nodes/mynode|resources.xml#J2CActivationSpec_1)
        

3. Save the configuration changes. See the Saving configuration changes with the wsadmin tool article for more information.

4. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with the wsadmin tool article for more information.
