Configure the queue sharing group

To use shared queues for high availability, use these topics as a step by step guide for configuring the queue sharing group.

When you have completed the steps in this part of the process for setting up the IBM MQ for z/OS system, we should Tailor the system parameter module to add queue sharing group data. We need to modify CSQ6SYSP to specify the QSGDATA parameter.

• Set up the Db2 environment
  If we are using queue sharing groups create the required Db2 objects by customizing and running a number of sample jobs.
• Set up the coupling facility
  If we are using queue sharing groups, define the coupling facility structures used by the queue managers in the queue sharing group (QSG) in the coupling facility Resource Management (CFRM) policy data set, using IXCMIAPU.
• Set up the SMDS environment
  To use SMDS to offload messages on shared queues, set up the SMDS offload storage environment.
• Add the IBM MQ entries to the Db2 tables
  If we are using queue sharing groups, run the CSQ5PQSG utility to add queue sharing group and queue manager entries to the IBM MQ tables in the Db2 data-sharing group.
• Implement ESM security controls for the queue sharing group
  Implement security controls for all queue managers in a queue sharing group, to access Db2 and the coupling facility list structures.
