Return and Reason Codes

z/OS MVS Programming: Workload Management Services

Return and Reason Codes

When the IWMEXPT macro returns control to your program:

  • GPR 15 (and retcode, when you code RETCODE) contains a return code.
  • When the value in GPR 15 is not zero, GPR 0 (and rsncode, when you code 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 39. Return and Reason Codes for the IWMEXPT Macro
Return CodeReason CodeEquate Symbol, Meaning, and Action
0Equate Symbol: IwmRetCodeOk

Meaning: Successful completion.

Action: None required.

4Equate Symbol: IwmRetCodeWarning

Meaning: Successful completion, unusual conditions noted.

4xxxx0433Equate Symbol: IwmRsnCodeEncAlreadyExported

Meaning: The input enclave was imported from another system. It cannot be exported by this system.

Action: The existing export token associated with the input enclave is returned. It can be used as long as it remains valid, which is under the control of the work manager that exported the enclave. Do not invoke IWMUEXPT to undo the export since this invocation did not establish the export.

8Equate 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.

8xxxx0821Equate Symbol: IwmRsnCodeBadConn

Meaning: Input connect token does not pass validity checking.

Action: Make sure the primary address space connected to WLM using the IWM4CON service. Make sure the connect token returned by IWM4CON is passed correctly.

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.

8xxxx0825Equate Symbol: IwmRsnCodeAscModeNotPrimary

Meaning: The caller invoked the service but was not in primary ASC mode.

Action: Avoid requesting this function in this environment.

8xxxx0827Equate Symbol: IwmRsnCodeRsvdNot0

Meaning: Reserved field in parameter list was non-zero.

Action: Check for use of keywords that are not supported by the z/OS® release on which the program is running.

8xxxx0828Equate Symbol: IwmRsnCodeBadVersion

Meaning: Version number in parameter list is not valid.

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

8xxxx083AEquate Symbol: IwmRsnCodeBadEnclave

Meaning: Enclave token does not pass verification.

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

8xxxx0840Equate Symbol: IwmRsnCodeServiceNotEnabled

Meaning: Caller's connection is not enabled for this service.

Action: Make sure that EXPTIMPT=YES is specified on the IWM4CON macro invocation.

8xxxx0842Equate Symbol: IwmRsnCodeNoWLMConnect

Meaning: Caller's primary address space is not connected to WLM.

Action: Invoke the IWM4CON macro before invoking this macro.

8xxxx0884Equate SymbolIwmRsnCodeEnclaveDefEx

Meaning: Enclave is marked Execution Start Time to be deferred.

Action: Such an enclave cannot be exported.

8xxxx08B7Equate Symbol: IwmRsnCodeWorkDepEnclave

Meaning: The requested service is not supported for a work-dependent enclave.

Action: Do not try to export work-dependent enclaves.

CEquate Symbol: IwmRetCodeEnvError

Meaning: Environmental error.

Cxxxx0C01Equate Symbol: IwmRsnCodeNoStg

Meaning: Virtual storage is not available for the request.

Action: Process the unit-of-work on the local system or fail the unit-of-work, whichever is appropriate.

Cxxxx0C2FEquate Symbol: IwmRsnCodeSystemSpace

Meaning: The enclave is owned by a system (i.e. limited-function) address space. Exporting such an enclave is not supported.

Action: Process the unit-of-work on the local system or fail the unit-of-work, whichever is appropriate.

Cxxxx0C37Equate Symbol: IwmRsnCodeStructureFull

Meaning: The coupling facility structure is full.

Action: Process the unit-of-work on the local system or fail the unit-of-work, whichever is appropriate.

Cxxxx0C36Equate Symbol: IwmRsnCodeStructureUnavailable

Meaning: WLM does not have access to its coupling facility structure.

Action: Process the unit-of-work on the local system or fail the unit-of-work, whichever is appropriate. Check for WLM or XES messages which describe the problem.

10Equate Symbol: IwmRetCodeCompError

Meaning: Component error.

Action: Contact your system programmer.
