Set the state for an enclave (ENCSTATE)

z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO
SA23-1375-00

Use the ENCSTATE SYSEVENT to set the state of an enclave to either idle or non-idle. Specify X'8000' in the ASID parameter. Access registers (AR) 0 and 1 must contain the enclave token. The enclave token must have been obtained from the IWMECREA macro. An independent enclave must not be set idle as long as there are non-idle work-dependent enclaves associated with it.

Input register information

Register 1 must point to a parameter list. The parameter list must be non-pageable and addressable via the caller's primary address space. To map the parameter list, use the IRAEVPL mapping macro described in z/OS MVS Data Areas in z/OS Internet Library at http://www.ibm.com/systems/z/os/zos/bkserv/.

Access register (AR) 0 and 1 must contain the enclave token whose state you are setting.
