Installing highly available WebSphere MQ for event processing

Sterling B2B Integrator receives an event from WebSphere® MQ to start processing. Files are always processed in the data center where the event is received.

For high availability, each data center must have an active queue manager and a standby queue manager for WebSphere MQ. Ensure that all the servers that host WebSphere MQ are connected with each other.

The following procedure is a high level list of tasks that must be completed to configure WebSphere MQ. For detailed information and steps, see WebSphere MQ on IBM® Knowledge Center.

Attention: The Global Mailbox installer validates if it can establish connection with the queue that is specified during Global Mailbox installation. At least one queue must be present and active in each data center for the installation to proceed, else the installation fails.

To configure highly available WebSphere MQ:

  1. Set up a multi-instance queue manager:
    1. Create an active queue manager instance.
    2. Create a standby queue manager instance.
    3. Verify the active and standby queue manager instances.
  2. Create a local queue to communicate events about processing files to Sterling B2B Integrator.
    Note:

    Use the same channel and queue name across all datacenters. You can either use the IBM MQ default Channel SYSTEM.DEF.SRVCONN or create a channel. For more information, see Create a Channel.

  3. Repeat steps 1 and 2 for all datacenters.
