Create an activation specification for the WebSphere MQ messaging provider

Use this task to create an activation specification for use with the WebSphere MQ messaging provider. To create an activation specification for use with the WebSphere MQ messaging provider, use the dmgr console to complete the following steps. Choose either to enter all the required connection information using the Create WebSphere MQ JMS resource wizard or to use a client channel definition table (CCDT) to establish a connection to the WebSphere MQ messaging provider.

For information about modifying an existing activation specification, see the related tasks.

  1. In the navigation pane, click Resources > JMS > Activation specifications.

  2. Select the Scope setting corresponding to the scope of the activation specification to create.

  3. Click New in the content pane.

  4. Select WebSphere MQ messaging provider, then click OK to start the Create WebSphere MQ JMS resource wizard.

  5. On the "Configure basic attributes" page, enter the following information, then click Next.

    Name

    The name by which this activation specification is known for administrative purposes within WAS.

    JNDI name

    The name used to bind this activation specification into the JNDI namespace.

    Description

    Optional. A description of this activation specification for administrative purposes within WAS.

  6. On the "Specify MDB destination data" page, enter the following information, then click Next.

    Destination JNDI name

    The JNDI name for the JMS destination from which messages are delivered to a MDB that is configured to use this activation specification.

    Message selector

    Optional. A message selector expression specifying which messages are to be delivered.

    Destination type

    The type of destination (queue or topic) from which to consume messages.

  7. On the "Select connection method" page, choose how to specify the connection details for to the WebSphere MQ messaging provider by selecting one of the following options, then click Next.

    Enter all the required information into this wizard

    Choose this option takes you to the "Supply queue manager details" page (see step 8), where we can start entering the connection details using the Create WebSphere MQ JMS resource wizard.

    Use a client channel definition table

    Choose this option takes you to the "Specify client channel definition table" page (see step 9), where we can enter details of the client channel definition table to use.

  8. If we have chosen to enter all the required information using the wizard...

    1. On the "Supply queue manager details" page, enter the name of the queue manager or queue-sharing group to connect to then click Next.

    2. On the "Enter connection details" page, specify the details for the connection, then click Next to continue to the "Test connection" page. Choose either to enter host and port information separately, or enter host and port information in the form of a connection name list. You must only choose the option to use a connection name list if you are creating a connection to a multi-instance queue manager. You must not use this option for connections to non-multi-instance queue managers as that can result in transaction integrity issues.

      Transport

      Optional. The WebSphere MQ transport type for the connection. The option that you select is used to determine the exact mechanisms used to connect to WebSphere MQ. If you are configuring a transport type of bindings, then client or bindings, see Configure the WebSphere MQ messaging provider with native libraries information for more information.

      Enter host and port information in the form of separate hostname and port values

      This radio button is selected by default and enables the Hostname and Port fields and disables the Connection name list field. Leave this radio button selected to enter host and port information in the form of separate hostname and port values.

      Hostname

      The host name, IPv4, or IPv6 address of the WebSphere MQ queue manager to connect to. Complete this field if we have selected Enter host and port information in the form of separate hostname and port values.

      Port

      Optional. The port number on which WebSphere MQ is listening. If we do not specify a value for the port number, the default value of 1414 is used. Complete this field if we have selected Enter host and port information in the form of separate hostname and port values.

      Enter host and port information in the form of a connection name list

      This radio button is cleared by default and, if selected, disables the Hostname and Port fields and enables the Connection name list field.

      • Click this radio button to select it to enter host and port information in the form of a connection name list.
      • Leave this radio button cleared to enter host and port information in the form of separate host name and port values.

      Connection name list

      The connection name list specifying the host name and port details to use when we want the connection factory to connect to a multi-instance queue manager. Complete this field if we have selected Enter host and port information in the form of a connection name list. Enter the host name and port details in the following form:

      host[(port)][,host(port)]

      host must be a valid TCP/IP host name or IPv4 or IPv6 address.

      port must be an integer value in the range 1 - 65536 (inclusive). The port information is optional, and if not specified, defaults to 1414.

      For example: localhost(1234),remotehost1(1234),remotehost2

      Server connection channel

      Optional. The WebSphere MQ server connection channel name used when connecting to WebSphere MQ queue manager or queue-sharing group.

  9. If we are using a channel client definition table to establish a connection to the WebSphere MQ messaging provider, complete the following fields on the "Specify client channel definition table" page, then click Next to continue to the "Test connection" page.

    Client channel definition table URL

    The URL to the client channel definition table to use when connecting to WebSphere MQ.

    Queue manager

    Optional. The name of the queue manager to be used to select one or more entries from the CCDT.

  10. Optional: On the "Test connection" page, to test establishing the connection, click Test connection. This test can take several seconds to perform.

  11. On the "Summary" page, complete the creation of the new activation specification by clicking Finish.
  12. Stop then restart the application server.
