Return resource contention information (QRYCONT)

Use SYSEVENT QRYCONT to return the resource contention information for either an address space or an enclave. You must specify the address space or enclave in the parameter list pointed to by register 1. 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/. Specify either the ASID or STOKEN value for the address space or the enclave token for the enclave. The enclave token must have been obtained from the IWMECREA macro or the IWMESQRY macro.

Input register information

Register 1 must point to a parameter list. The parameter list must be non-pageable for authorized SYSEVENT calls (ENTRY=SVC, ENTRY=BRANCH) and must be 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/.

Return codes

When processing is complete for the SYSEVENT QRYCONT, the last byte of register 15 contains one of the following hexadecimal return codes:

Table 1. Return Codes for REQLPDAT
Return Code (decimal)	Meaning
00	Successful completion.
04	No contention information available.
08	Invalid enclave token specified.
10	The ASID specified did not map to a valid, active address space. This may occur because the address space it represents is no longer active or was never active.
12	The STOKEN specified did not map to a valid, active address space. This may occur because the address space it represents is no longer active or was never active.
14	Invalid combination of ASID, STOKEN, or enclave token was specified in the parameter list. Specify either ASID, STOKEN, or enclave token.
16	There is additional resource contention information available.
18	Invalid version, length, or eye catcher was specified in the parameter list.
20	Invalid request type was specified in the parameter list.
