Intrapartition transient data queues

"Intrapartition" refers to data on direct-access storage devices for use with one or more programs running as separate tasks. Data directed to or from these internal queues is referred to as intrapartition data; it must consist of variable-length records. All intrapartition transient data destinations are held as queues in the same VSAM data set, which is managed by CICS. An intrapartition destination requires a resource definition containing information that locates the queue in the intrapartition data set. Intrapartition queues can be associated with either a terminal or an output data set. When data is written to the queue by a user task, the queue can be used subsequently as input data by other tasks within the CICS region. All access is sequential, governed by read and write pointers. Once a record has been read, it cannot be read subsequently by another task. Intrapartition data may ultimately be transmitted upon request to the terminal or retrieved sequentially from the output data set.

Typical uses of intrapartition data include:

There are three types of intrapartition transient data queue:
