Configuring a J2C activation specification in WebSphere Application Server

You must configure a new J2C activation specification from the IMS TM resource adapter and then specify the values for communication with IMS.

1. Create a J2C specification for the IMS TM resource adapter.
   1. Create a J2C specification for the IMS TM resource adapter. In the administrative console (also known as the Integrated Solutions Console) of WebSphere Application Server, select Resources > Resource Adapters > J2C activation specifications in the navigation pane.

   2. Click New in the content pane.
      A Configuration tab is displayed.
   3. Under Provider, select the IMS TM resource adapter from the list.
      The Message listener type field at the bottom of this page is automatically populated based on the selection.
   4. Specify a name for this J2C activation specification.
      For example, IMSActivationSpec.
   5. Type the JNDI name.
      For example, eis/IMSActivationSpec.
   6. Click Apply.
      You are back to the J2C activation specifications page.
   7. Click Save in the message box at the top to save the changes to the master configuration.
      The J2C activation specification is created.

2. To configure the J2C activation specification for use with the IMS TM resource adapter:
   1. Click the name of the J2C activation specification for the IMS TM resource adapter.
      The Configuration tab is displayed.
   2. Under the Additional Properties section on the side, click the J2C activation specification custom properties link.
      Custom properties in this instance of J2C activation specification are displayed.

      Note: The properties in the following figure might not match the properties that you see, depending on your version of the IMS TM resource adapter.

   3. Specify the values for the following required properties by clicking their names in the table and entering the appropriate values.
      • queueName: A comma-delimited list of the tpipe hold queue names where the callout requests from IMS are being held.
      • portNumber: the port number for IMS Connect
      • hostName: the IMS Connect host name
      • dataStoreName: the IMS data store name.

        In WebSphere Application Server Version 8 or later, the data store name can be a comma-delimited list of names, enabling an IMSActivationSpec instance to pull callout messages from multiple data stores.

   4. If you want the IMS TM resource adapter to use connection pooling for responses that are sent back to IMS, specify values for the following properties:
      • connectionPoolEnabled: whether IMS TM resource adapter should use connection pooling (specify true to enable this feature)
      • maxConnections: the maximum number of connections that the connection pool can hold
      • poolCleanupFrequency: the cleanup interval (in minutes) for idle connections in the connection pool
      • ddurationOfIdleConnections: the number of minutes that a connection in the connection pool can remain idle before it is cleaned up at the next cleanup interval
   5. If you want the IMS TM resource adapter to receive an acknowledgment from IMS when IMS receives a synchronous callout response message, specify true for the sendOnlyWithAck property.
   6. Specify the values for the other optional properties based on your environment.
   7. Click Apply.
   8. Click Save in the message box at the top to save the changes to the master configuration.
