XRF HAS FAILED. ERROR NUMBER nn ON XRF MESSAGE DATA SET IN CONTROL INTERVAL WITH RBA HEX'xx'.
Explanation:

The XRF message manager has encountered a problem with the contents of the given control interval in the message data set. The message includes an error number nn which can take one of the following values:

01
The CI does not contain an XRF message manager control record.
02
The XRF message control record contains a cycle number less than that of the current read cycle.
03
The XRF message manager did not find a message record boundary where it expected one.
04
There is an XRF message sequence number error.
05
The CIDF is invalid (for example, the free area length is negative).
06
The length in the RDF is less than the length of a message record header, or is inconsistent with the data length in the message record header.
07
The end of the record lies outside the data area defined by the data length field of the CIDF.
System action:

Surveillance by the alternate system ceases.

User response:

Check that the active and alternate systems are using the same pair of data sets for XRF surveillance. If they are, this is almost certainly a CICS error affecting either the alternate system, the active system, or both.

You need further assistance from IBM to resolve this problem. See CICS® Problem Determination Guide for guidance on how to proceed.

XRF HAS FAILED. THE XRF MESSAGE READER IN THE ALTERNATE SYSTEM HAS FALLEN TOO FAR BEHIND.
Explanation:

The alternate system has been unable to keep up with the messages generated by the active CICS system. Its read position in the wrap-round message data set has been ‘lapped’ by the active system.

System action:

Surveillance by the alternate system ceases.

User response:

Try to determine and correct the reason for the delay to the alternate system. It may be that the message data set is too small to allow adequate buffering, or the message data set has been reserved by the active CEC - not necessarily by the active CICS.

DFHXA6561D
applid WHEN jesno jobname ENDS REPLY 'JOB' OR WHEN CEC sid HAS FAILED REPLY 'CEC'.
Explanation:

During a takeover attempt, the issuing CICS system was unable to determine whether job jobname, running on a different CEC, has terminated. This is for one of the following reasons:

If jobname is the active CICS. Takeover cannot continue until jobname has ended. If jobname is a DBCTL subsystem, an alternate DBCTL cannot be started until jobname has ended.

System action:

The system waits for a reply. In the meanwhile, the issuing CICS system continues processing to detect termination of the job.

If termination is detected while the reply is still outstanding, this message is deleted and message DFHXA6564 is displayed. In this case, a reply is no longer required.

If the reply is ‘JOB’, then processing continues as if CICS had detected the termination itself.

This also happens if the reply is ‘CEC’, but in addition an internal record is created indicating that the CEC is inoperative at this time. Other alternate CICS which have issued this message for jobs executing on the CEC specified, and which are still waiting for a reply, will detect the internal record of the failed CEC. Having done so they delete their outstanding replies and issue message DFHXA6563.

User response:

The operator should either:-

No action is necessary if at any time CICS deletes this message, as described above.

PROGRAM LOGIC ERROR DETECTED.
Explanation:

An internal error has been detected that prevents the CICS XRF CAVM supervisor state processing from continuing.

Depending on the CAVM supervisor state service being processed at the time, CICS may or may not abnormally terminate.

The CAVM TCB for processing the service has abnormally terminated.

Job output should include a dump of MVS LSQA associated with the SYSABEND DD statement.

Diagnostics: Register 2 is the base register for DFHWTI global storage. This storage begins with the eye catcher WTISTOR. The format of this storage is defined in DSECT WSTORAGE in source member DFHWTI.

DFHWTI request arguments copied to global storage begin at field WGLODATA.

Source member DFHWTADS defines the format of global storage arguments.

Field WGLOLOCA contains the address of the first register save area for a routine in DFHWTI.

In the SVRB for the CICS SVC call that invoked DFHWTI, the first fullword in the FEPARM field contains the address of DFHWTI global storage.

Register 4 is the base register for local storage for each routine in DFHWTI. Its format is defined in a DSECT whose name is of the form WLOCxxx where xxx is the short name of the routine (see below for a list of routine names).

These DSECTs are in source member DFHWTI. The first halfword is the internal return code for the routine. The values used for internal return codes are the same as the DFHWTI request reason codes as defined in source member DFHWTADS field name WTARRC.

In addition, internal return codes of the format X'40nn' are used.
X'40F0' is ‘Internal Logic Error’ variable name, RCLOGERR.

Other internal return codes of this format are defined in the local storage DSECTs.

The DFHWTI request type for the CAVM supervisor state service is copied into local storage associated with the DFHWTI initialization and termination routine, field name WWTIREQ, DSECT WLOCWTI in source member DFHWTI.

Register 6 is the base register for each routine in DFHWTI. When set, it points at a location immediately following an eye catcher of the routine’s long name (see list of routine names).

Register 13 is the base register for a register save area local to a routine in DFHWTI. These save areas are standard MVS format except the first fullword contains the routine’s short name (see list of names). They are chained in the standard way with backward and forward pointers set on entry to a routine and zeroed on return.

Register save areas physically precede the storage local to a routine.

If a routine has to access the CLT, its address is in local storage for the routine. The field name for the CLT address is of the form WxxxCLTA, where xxx is the short name of the routine.

System action:

In general, the CAVM request issued by this CICS job will fail. For the effect this has on processing by this CICS job, refer to messages issued after this one.

CAVM XRF supervisor state processing issues an MVS abend with system abend code 0214 and an MVS SYSABEND dump is produced.

User response:

Keep the job output and console log for problem determination.

Using the SYSABEND dump of the MVS LSQA, and if available, the MVS symptom dump output, find the DFHWTI routine that detected the error from the value of register 6 or register save area chain fields.

Find the internal return code currently set in local storage for the routine.

Using the reason code value, remaining content of local storage and global storage, try to determine the cause of the action by the routine.

An assembly listing of the CLT assembled with the PRINT NOGEN option may be required.

applid UNABLE TO DETERMINE STATUS OF JOB jesno jobname.
Explanation:

The issuing CICS system was unable to determine whether job jobname, running on the same CEC, has terminated. This is for one of the following reasons:

  1. CICS was unable to issue a system operator command under program control to cancel the named job. In this case, message DFHXA6560 has been produced.
  2. CICS has successfully issued a cancel command, but the job still appears to be running after the time period specified by the initialization parameter JESDI.
  3. Job jobname is a failing DBCTL subsystem, but the job still appears to be running after the time period specified by the initialization parameter JESDI.

If jobname is the active CICS, takeover cannot continue until jobname has ended.

If jobname is a DBCTL subsystem, an alternate DBCTL cannot be started until jobname has ended.

System action:

Takeover is suspended until the issuing CICS system detects the termination of the named job.
