DFS7431I IFAWIC connection failed - RC= xxxxxxxx, RSN= yyyyyyyy
Explanation
IMS attempted to register with IBM® z/OS® Workload Interaction Correlator and received a nonzero return code xxxxxxxx with a reason code yyyyyyyy. The value for xxxxxxxx can be one of the following values:
- RC 00000004
- The combined length of the persistent component and activity areas, together with the BPE overhead, was larger than the maximum number of pages that are allowed for an IBM z/OS Workload Interaction Correlator buffer. An IBM z/OS Workload Interaction Correlator buffer currently allows 16 4K pages at maximum. For INITMT, the reason might also be either one of the lengths of the persistent component or activity areas, or the lengths of both, were negative.
- RC 00000008
- One or both of the persistent component length and activity areas length were not a multiple of 16. The length is required to be a multiple of 16 to preserve quadword alignment for instructions like CDSG. This return code is only for INITMT.
- RC 0000000C
- The SMF 98 subtype value was zero. This return code is only for INITMT.
- RC 00000010
- The address that was passed in BPEMTSRV_OUTBUFPTR was zero. This return code is only for INITMT.
- RC 00000030
- IBM z/OS Workload Interaction Correlator (Micro-Trend) services are not available on this system.
- RC 00000034
- The LOAD request of BPEMTX00 failed. yyyyyyyy contains the return code from the LOAD request.
- RC 00000038
- The LOAD request of BPEMTEN0 failed. yyyyyyyy contains the return code from the LOAD request.
- RC 0000003C
- The ENFREQ request for BPEMTEN0 failed. yyyyyyyy contains the return code from the ENFREQ request.
- RC 00000040
- IFAWIC registration received higher than a warning RC. yyyyyyyy contains the reason code returned by IFAWIC. See the IFAWIC documentation in the z/OS MVS™ Programming: Authorized Assembler Services Reference EDT-IXG manual for details.
- RC 00000044
- The BPEMTSRV call is not supported in a cloned copy of BPE.
- RC 000000F8
- The function requested is unknown.
- RC 000000FC
- The parmlist version is not supported by BPEMTSV0.
Note: This message will be suppressed when IMS runs on a pre-z14 machine,
or if IBM z/OS Workload Interaction Correlator is not available, or
both.
System action
IMS continues processing with no statics being passed to IBM z/OS Workload Interaction Correlator.
Programmer response
If IBM z/OS Workload Interaction Correlator participation is needed, see the return and reason codes to determine the cause of failure, fix the problem and restart IMS.
