Return and Reason Codes
When the IWMMEXTR 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 113. Return and Reason Codes for the IWMMEXTR MacroReturn Code | Reason Code | Equate Symbol, Meaning, and Action |
---|
0 | — | Equate Symbol: IwmRetCodeOk
Meaning: Successful completion.
Action:
None required. | 4 | — | Equate Symbol: IwmRetCodeWarning
Meaning: Successful completion, unusual conditions
noted. | 4 | xxxx0402 | Equate Symbol: IwmRsnCodeNoMonEnv
Meaning: Monitoring token indicates that no monitoring
environment exists.
Action: None required. | 4 | xxxx040C | Equate Symbol: IwmRsnCodeMonEnvLacksInfo
Meaning: Input monitoring environment does not contain
the necessary information to return the data requested.
Action: None required. | 8 | — | Equate Symbol: IwmRetCodeInvocError
Meaning: Invalid invocation environment or parameters. | 8 | xxxx0820 | Equate Symbol: IwmRsnCodeBadMonEnv
Meaning: Monitoring environment does not pass short
form verification.
Action: Check for possible
storage overlay. | 8 | xxxx0895 | Equate Symbol: IwmRsnCodeEWLMServNotEnabled
Meaning: Service is not enabled because monitoring
environment can not be associated with EWLM work requests.
Action: Specify the parameter EWLM_CHCORR or EWLM_PACTKN
only when the monitoring environment is created with IWMMCREA EWLM=YES
or the address space is connected with IWMCONN EWLM=YES and the connect
token is passed to IWMMCREA when creating the monitoring environment. | 8 | xxxx08AC | Equate Symbol: IwmRsnCodeTranNotStarted
Meaning: A work unit has not been started.
Action: Start a work unit by IWMMSTRT macro, before
specifying the EWLM_S_CURCORR parameter. |
