z/OS: Adding a new queue-sharing group to an existing Db2 data sharing group in the latest version

Follow these steps to add a new queue-sharing group to an existing Db2® data sharing group in the latest version of the product. You must apply the migration and toleration PTFs to queue managers, in the previous version, in any of the queue-sharing groups before adding a queue-sharing group.

Before you begin

  1. Review your Db2 data-sharing requirements. A single Db2 data-sharing group can be used to support multiple IBM® MQ queue-sharing groups.
  2. You can add a new queue-sharing group to a Db2 data-sharing group that already supports IBM MQ queue-sharing groups containing queue managers for the previous version. You must ensure that the migration and toleration PTFs have been applied. The Db2 tables used by IBM MQ must be configured for the latest version queue managers.
