Enclave termination

The storage tuning user exit is called after the assembler user exit is called for enclave termination. At this point the storage tuning user exit is passed information about the main program, a user word, and the storage tuning information.

When running on non-CICS or on CICS® without automatic storage tuning, the storage tuning user exit can do the following:

Take the storage tuning information for the program that you want to tune, and put the information in a file or in an incore table. The tuning information can be saved and used in the enclave initialization call the next time the program is used. Or the tuning information may be written to a file and processed at a later time to determine the best tuning values.

When running on CICS with automatic storage tuning, the storage tuning user exit can do the following:

Provide storage options values to override the values set by Language Environment® automatic storage tuning.

Note: At enclave initialization, if the storage tuning user exit does not request Language Environment to collect storage tuning information, then Language Environment will not call the storage tuning user exit at enclave termination.
