Return and Reason Codes

z/OS MVS Programming: Workload Management Services

Return and Reason Codes

When the IWMPACT 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 43. Return and Reason Codes for the IWMPACT 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.

4xxxx0414Equate Symbol: IwmRsnCodeNullCDS

Meaning: This request could not be completed because no Service definition has been installed on the WLM CDS.

Action: None required.

4xxxx0415Equate Symbol: IwmRsnCodePolicyActInProgress

Meaning: This request could not be completed because another policy activation request is currently being processed. If specified, the SYSTEM_NAME parameter will contain the name of the system on which policy activation is in progress.

Action: None required. If this service is re-invoked at a later time it may be successful.

4xxxx0416Equate Symbol: IwmRsnCodePolicyUndefined

Meaning: The service policy specified could not be found in the service definition currently installed on the WLM couple data set. The service policy was not activated.

Action: None required. Verify that the policy was specified correctly.

8Equate Symbol: IwmRetCodeInvocError

Meaning: Invalid invocation environment or parameters.

8xxxx0801Equate Symbol: IwmRsnCodeSrbMode

Meaning: The caller is in SRB mode.

Action: Avoid requesting this function while in SRB mode.

8xxxx0803Equate Symbol: IwmRsnCodeDisabled

Meaning: Caller is disabled.

Action: Avoid requesting this function while disabled.

8xxxx0804Equate Symbol: IwmRsnCodeLocked

Meaning: The caller is locked.

Action: Avoid requesting this function while locked.

8xxxx0810Equate Symbol: IwmRsnCodeEutFrr

Meaning: The caller has EUT FRR established.

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

8xxxx0823Equate Symbol: IwmRsnCodeDatoff

Meaning: The caller invoked the service while DATOFF

Action: Avoid requesting this function in this environment.

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.

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 or the length specified is incorrect.

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

8xxxx0841Equate Symbol: IwmRsnCodeXMemMode

Meaning: The caller is in cross memory mode.

Action: Invoke the function in non-cross memory mode.

CEquate Symbol: IwmRetCodeEnvError

Meaning: Environmental error.

Cxxxx0C01Equate Symbol: IwmRsnCodeNoStg

Meaning: Storage is not available for the request.

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

Cxxxx0C0EEquate Symbol: IwmRsnCodeInsufAccess

Meaning: The RACF® facility class is active and a profile has been defined for the MVSADMIN.WLM.POLICY RACF facility class profile to which the caller does not have sufficient (update) access.

Action: Invoke the function when the conditions are alleviated.

Cxxxx0C0FEquate Symbol: IwmRsnCodeCDSNotAvail

Meaning: A couple data set for WLM has not been defined or it has been defined but this system does not have connectivity to the data set.

Action: No action required.

Cxxxx0C10Equate Symbol: IwmRsnCodeCDSTooSmall

Meaning: WLM CDS is too small to process the request.

Action: No action required.

Cxxxx0C11Equate Symbol: IwmRsnCodeOneSystemUnable

Meaning: At least one system in the sysplex was unable to activate the policy. One or more systems may have been successful in activating the policy.

Action: No action required.

Cxxxx0C13Equate Symbol: IwmRsnCodePolicyNotAvail

Meaning: The service policy specified could not be verified because the service definition retrieved from WLM CDS has failed validation. The service policy was not activated.

Action: No action required.

Cxxxx0C1EEquate Symbol: IwmRsncodeHigherVersionLevel

Meaning: The policy cannot be activated on this system because the service definition in the WLM couple data set is at a higher level than the WLM code on this system. A system with a lower level version cannot activate this service policy because it is not capable of handling all the function in the service definition.

Action: None required. If necessary, reinvoke the service on a higher level system.

10Equate Symbol: IwmRetCodeCompError

Meaning: Component error.

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