TDQUEUE resource definitions

A TDQUEUE definition defines the attributes of a transient data queue.

The following transient data resources can be managed using RDO:

Intrapartition definitions contain attributes that provide information about recovery characteristics, trigger levels, associated transactions, facilities, and userids.

Extrapartition definitions contain information about the associated QSAM data set, and the number of buffers that are to be used.

Indirect definitions identify the underlying queue name.

Remote definitions contain the name of the remote system and the name by which the queue is known on that remote system.

Before a transient data queue can be used by an active CICS® system, you must install its definition in the running system. CICS uses the definition to access the data set associated with the queue, and records the number of read and write operations on the queue.

Remote transient data queues can be defined using the CEDA transaction in one of two ways:

You can use CEDA to define and redefine transient data resources in groups on the CSD file, from where they can be installed on the CICS region. You can also use CEDA to remove these resources. Figure 1 shows the TDQUEUE resource definition screen with the various default values displayed. These defaults are appropriate only for specific queue types.
