Return and Reason Codes

z/OS MVS Programming: Workload Management Services

Return and Reason Codes

When the IWMMINIT 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 114. Return and Reason Codes for the IWMMINIT Macro
Return CodeReason CodeEquate Symbol, Meaning, and Action
0—IwmRetCodeOk: Successful completion.
4—IwmRetCodeWarning: Successful completion, unusual conditions noted.
4xxxx0402Equate Symbol: IwmRsnCodeNoMonEnv

Meaning: Monitoring token indicates that no monitoring environment exists.

8—IwmRetCodeInvocError: Invalid invocation environment or parameters
8xxxx081EEquate Symbol: IwmRsnCodeBadLU62TknLen

Meaning: The length byte of the LU62 token has an invalid value. Only values 1-36 (decimal) are valid.

8xxxx0820Equate Symbol: IwmRsnCodeBadMonEnv:

Meaning: Monitoring environment does not pass short form verification.

8xxxx0894Equate Symbol: IwmRsnCodeInvalidEWLMCorr

Meaning: Passed correlator information (EWLM_PACORR or EWLM_PACTKN) does not pass validity checking, that means: the architected ARM correlator length field in the first two Bytes of the correlator (token) is either less than 4 ('0004'x) or greater than 512 ('0200'x).

Action: Check the specification of the correlator information.

8xxxx0895Equate Symbol: IwmRsnCodeEWLMServNotEnabled

Meaning: Service is not enabled because the Monitoring Environment was not created with EWLM=YES (either on IWMCONN or IWMMCREA).

Action: Specify the parameter EWLM_PACORR or EWLM_PACTKN only when the Monitoring Environment was created with EWLM=YES (either on IWMCONN or IWMMCREA).

C—IwmRetCodeEnvError: Environmental error
Cxxxx0C07Equate Symbol: IwmRsnCodeNoArrTime:

Meaning: No arrival time was supplied to the service and STCK gave a non-zero condition code.

Cxxxx0C08Equate Symbol: IwmRsnCodeNoExTime:

Meaning: No execution start time was supplied to the service and STCK gave a non-zero condition code.
