Return and Reason Codes

z/OS MVS Programming: Workload Management Services

Return and Reason Codes

When the IWMEBLK macro returns control to your program:

  • GPR 15 (and retcode, if you coded RETCODE) contains a return code.
  • When the value in GPR 15 is not zero, GPR 0 (and rsncode, if you coded RSNCODE) contains reason code.

The following table identifies the hexadecimal return and reason codes and the equate symbol associated with each reason code. IBM® support personnel may request the entire reason code, including the xxxx value.

Table 27. Return and Reason Codes for the IWMEBLK Macro
Return CodeReason CodeEquate Symbol, Meaning, and Action
0—Equate Symbol: IwmRetCodeOk

Meaning: Successful completion.

Action: None required.

8—Equate Symbol: IwmRetCodeInvocError

Meaning: Invalid invocation environment or parameters.

8xxxx0803Equate Symbol: IwmRsnCodeDisabled

Meaning: Caller is disabled.

Action: Avoid requesting this function while disabled.

8xxxx0804Equate Symbol: IwmRsnCodeLocked

Meaning: Caller is locked.

Action: Avoid requesting this function while locked.

8xxxx080BEquate Symbol: IwmRsnCodeBadPl

Meaning: Error accessing parameter list.

Action: Check for possible storage overlay.

8xxxx0824Equate Symbol: IwmRsnCodeAmode24

Meaning: The caller invoked the service but was in 24-bit addressing mode.

Action: Request this function only when you are in 31-bit addressing mode.

8xxxx0828Equate Symbol: IwmRsnCodeBadVersion

Meaning: The Version number in the parameter list is not valid.

Action: Check for possible storage overlay of the parameter list.

8xxxx083AEquate Symbol: IwmRsnCodeBadEnclave

Meaning: EWLMMODE=EXPLICIT_SINGLE was specified and the required enclave token does not pass verification.

Action: Check for possible storage overlay of the enclave token, or for asynchronous events which may have deleted the enclave.

8xxxx0895Equate Symbol: IwmRsnCodeEWLMServNotEnabled

Meaning: The service is not enabled because the caller invoked the IWM4CON (IWMCONN) service with EWLM=NO.

Action: Ensure that EWLM=YES is specified on the IWM4CON (IWMCONN) request to enable this service.

8xxxx0896Equate Symbol: IwmRsnCodeBadWorkReqHandle

Meaning: The work request handle is invalid.

Action: Check the specification of the WORKREQ_HDL parameter.

8xxxx08A0Equate Symbol: IwmRsnCodeNotExplicitSingle

Meaning: The service has been invoked with option EWLMMODE=EXPLICIT_SINGLE but the enclave has not been created with the ESTRT=EXPLICIT_SINGLE option or vice versa.

Action: If ESTRT=EXPLICIT_SINGLE was coded on the IWM4ECRE or IWMECREA call, EWLMMODE=EXPLICIT_SINGLE must also specified on the IWMEBLK call. If ESTRT=EXPLICIT OR ESTRT=IMPLIED was coded on the IWM4ECRE or IWMECREA call, EWLMMODE=NORMAL must be specified on the IWMEBLK call (or the EWLMMODE parameter can be omitted).

10—Equate Symbol: IwmRetCodeCompError

Meaning: Component error.

Action: No action required. The function may be successful if invoked again.
