Defining storage for reports

When a user performs a QMF task that retrieves, imports, or exports data, the data is held in storage until the operation is complete. In both CICS® and TSO, you can set a fixed upper limit for the amount of virtual storage, also called active storage, to be used for these operations. In TSO, you can also specify a percentage or portion of available storage to be used for reports.

About this task

To improve QMF performance in both TSO and CICS, you can also specify additional storage to be used to hold data no longer needed in active storage; this type of storage is called spill storage. You can spill data to extended virtual storage or a file.
