Return and Reason Codes

z/OS MVS Programming: Workload Management Services

Return and Reason Codes

When the IWMMCREA 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.

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.

4xxxx0409Equate Symbol: IwmRsnCodeNoConn

Meaning: Connect token does not reflect a successful Connect. The delay monitoring token returned is useable in other services. However use of this token will NOT result in the action requested of those services.

Action: None required.

8Equate Symbol: IwmRetCodeInvocError

Meaning: Invalid invocation environment or parameters.

8xxxx0801Equate Symbol: IwmRsnCodeSrbMode

Meaning: Caller is in SRB mode.

Action: Avoid requesting this function while in SRB mode.

8xxxx0802Equate Symbol: IwmRsnCodeXmemUserKeyTkn

Meaning: Caller is in cross-memory mode while the token was requested in user key.

Action: Avoid requesting this function while in cross-memory mode.

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.

8xxxx0810Equate Symbol: IwmRsnCodeEutFrr

Meaning: Caller has EUT FRR established.

Action: Avoid requesting this function with an EUT FRR set.

8xxxx0821Equate Symbol: IwmRsnCodeBadConn

Meaning: Input connect token does not pass validity checking.

Action: Check for possible storage overlay.

8xxxx0823Equate Symbol: IwmRsnCodeDatoff

Meaning: Caller invoked service while DATOFF

Action: Avoid requesting this function in this environment.

8xxxx0824Equate Symbol: IwmRsnCodeAmode24

Meaning: Caller invoked 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: Caller invoked service but was not DAT on Primary ASC mode.

Action: Avoid requesting this function in this environment.

8xxxx0826Equate Symbol: IwmRsnCodeTaskTerm

Meaning: Caller invoked service while task termination is in progress for the TCB associated with the owner.

Action: Avoid requesting this function in this environment.

8xxxx0827Equate Symbol: IwmRsnCodeRsvdNot0

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

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

8xxxx0828Equate Symbol: IwmRsnCodeBadVersion

Meaning: Version number in parameter list is not valid.

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

8xxxx0829Equate Symbol: IwmRsnCodeBadOptions

Meaning: Parameter list omits required parameters or supplies mutually exclusive parameters or provides data associated with options not selected.

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

8xxxx0844Equate Symbol: IwmRsnCodeBadMonTknListLen

Meaning: The storage area length specified on the MONTKN_LISTLEN parameter is not large enough to contain the data being returned. No data is returned.

Action: Invoke the function with an output area sufficient to receive the data.

CEquate Symbol: IwmRetCodeEnvError

Meaning: Environmental error.

Action: There is a storage shortage. The function may work successfully at a later time.

Cxxxx0C09Equate Symbol: IwmRsnCodeNoResmgr

Meaning: Resource manager could not be established.

Action: No action required. This condition may be due to a storage shortage condition.

10Equate Symbol: IwmRetCodeCompError

Meaning: Component error.

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