Managing queue name translations

This description is mainly provided for application designers and channel planners concerned with an individual system that has message channels to adjacent systems. It takes a local view of channel planning and control.

When you create a queue manager alias definition or a remote queue definition, the name resolution is carried out for every message carrying that name, regardless of the source of the message. To oversee this situation, which may involve large numbers of queues in a queue manager network, you keep tables of:

• The names of source queues and of source queue managers with respect to resolved queue names, resolved queue manager names, and resolved transmission queue names, with method of resolution
• The names of source queues with respect to:
  • Resolved destination queue names
  • Resolved destination queue manager names
  • Transmission queues
  • Message channel names
  • Adjacent system names
  • Reply-to queue names

Note:

The use of the term source in this context refers to the queue name or the queue manager name provided by the application, or a channel program when opening a queue for putting messages.

An example of each of these tables is shown in Table 4, Table 5, and Table 6.

The names in these tables are derived from the examples in this chapter, and this table is not intended as a practical example of queue name resolution in one node.

Table 5. Queue name resolution at queue manager QMB
