HEAP (non-CICS)

HEAP controls the allocation of the initial heap, additional heaps created with the CEECRHP callable service, and specifies how that storage is managed.

When Fortran is the only selected language, values for HEAP will be changed to (4K,4K,ANY,KEEP,8K,4K) .

HEAP has the following suboptions :

Notes :

  • z/OS UNIX System Services consideration : The HEAP option applies to the enclave. Heap storage is managed at the thread level using pthread_key_create, phtread_setspecific, and pthread_getspecific.
