Return and Reason Codes
When the IWMMUPD 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 a 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 119. Return and Reason Codes for the IWMMUPD Macro| Return 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: The input monitoring token indicates no
monitoring environment was established.
Action:
Establish a monitoring environment by macro IWM4MCRE. | | 4 | xxxx0441 | Equate Symbol: IwmRsnCodeTooManyMsgCorrs
Meaning: The correlator passed to EWLM_RCVD_CORR
is ignored, since the maximum number of supported correlators has
been reached.
Action: None required. | | 4 | xxxx0443 | Equate Symbol: IwmRsnCodeTooManyMsgsSent
Meaning: The value passed to MESSAGES_SENT is ignored,
since the maximum number of messages sent is reached.
Action: None required. | | 4 | xxxx0444 | Equate Symbol: IwmRsnCodeTooManyMsgsReceived
Meaning: The EWLM_RCVD_CORR parameter has been specified
too often. The correlated counter is not increased.
Action: None required. | | 8 | — | Equate Symbol: IwmRetCodeInvocError
Meaning: Invalid invocation environment or parameters. | | 8 | xxxx0820 | Equate Symbol: IwmRsnCodeBadMonEnv
Meaning: Input monitoring environment does not pass
short form validity checking.
Action:
Check for possible storage overlay. | | 8 | xxxx08AC | Equate Symbol: IwmRsnCodeTranNotStarted
Meaning: No work unit has been started by IWMMSTRT
for the specified monitoring environment.
Action:
Start a work unit by IWMMSTRT macro, before issuing this macro. |
