Start of changeThe failing operation is shown in the message, and is a DELETE, WRITE_NEXT, START_WRITE or END_WRITE. request.

This is normally an internal CICS error, however, it can occur during shut down if one task initiates a normal shut down, and another initiates an immediate shut down shortly afterwards. This is because the immediate shut down closes resources that are being used by the normal shut down task.End of change

Start of changeThis can also occur if the global catalog is not big enough and a large group is being installed.End of change

Start of change
System action:

CICS terminates.

End of change

User response:

Check the size of the global catalog. Redefine a larger one if necessary.

Alternatively this message could be caused by an immediate shutdown of CICS because tasks not yet quiesced may abend trying to access a service removed by the shutdown process.

DFHXG6491
applid Logic error during session tracking. REASON rcode terminal/session event
Explanation:

XRF session tracking encountered an unexpected circumstance probably due to a design error. The reason code (rcode) is one of the following.

1
POST called but no pending action for terminal or session.

Inserts:

  • name of terminal or session.
2
DFHZXST called with bad request value.
3
XRF-capable session lacks a correlation id.

Inserts:

  • name of terminal or session,
  • code for event being tracked.

The following are valid for DFHSUSX only.

  • X'01'--Send sign on data
  • X'02'--Send sign on data (catchup)
  • X'03'--Receive sign on data

The following are valid for DFHZXST only.

  • X'F1'--BIND
  • X'F2'--Free LOGON data
  • X'F3'--UNBIND
4
Could not get key to build tracking message.

Inserts:

  • name of terminal or session
  • code for event being tracked (see 3 above)
5
Could not get send tracking message.

Inserts:

  • name of terminal or session
  • code for event being tracked (see 3 above)
6
Could not find session named in tracking message.

Inserts:

  • name of terminal or session
  • code for event being tracked (see 3 above)
7
Illegal entry named in tracking message.

Inserts:

  • name of terminal or session
  • code for event being tracked (see 3 above)
8
Bad request code in tracking message.

Inserts:

  • name of terminal or session
  • bad request code (see 3 above for valid DFHZXST codes)
9
Correlator in tracking message is longer than 8.

Insert:

  • name of terminal or session
10
Unable to schedule standby BIND.

Insert:

  • name of terminal or session.
System action:

Normal processing continues.

User response:

Note the message. Resources and states may be incorrect should the backup take over. If many of these messages are issued, then it is likely that there is a more general problem.

DFHXG6492I
applid XRF catch-up logic error reason length
Explanation:

The XRF catch-up program encountered an unexpected circumstance probably due to a CICS design error. The reason, indicated by the first insert, is one of the following:

1
Catalog record internal length value not correct.
2
Catalog record format error. There is no room for a key.
3
Catalog record format error. The key is longer than 16.
4
Catalog record too long for buffer (variable CUBUFFER). The second insert gives the required length.
5
Unexpected ABEND or response from EXEC CICS command.
6
Catalog record format error. There is no resource manager prefix.
System action:

In cases 1, 2, 3, and 6 above, normal processing continues.

In case 4, DFHZXCU abends with abend code AZXB. In case 5, DFHZXCU abends with abend code AZXA.

User response:

Note the message. Resources and states may be incorrect should the alternate take over. If many of these messages are issued, it is likely that there is a more general problem.

Start of change
Explanation:

The XRF catch-up program obtained a bad return code from the XRF message manager and was unable to send a record that the alternate would require to obtain a correct copy of the active. The inserts (internal diagnostic information) are:

  1. WMSRETC

    DFHWMS return code. (For values and meanings of the return codes, refer to the XRF CICS manager request interface block (WMSPS) listing in the CICS Data Areas.)

  2. WMSREASN

    DFHWMS reason code. (For values and meanings of the reason codes, please refer to the XRF CICS manager request interface block (WMSPS) listing in the CICS Data Areas.)

  3. XTR-KEY-VALUE is the key of the tracking record.
  4. XTR-ID is the record ID, where
    • zero = tracking, and
    • non-zero = catch-up.
  5. XTR-TYPE is the record type (see DFHZXTR), where
    • X = tracking control,
    • C = TCT contents,
    • S = ZCP session tracking, and
    • U = sign on data

The message is issued from module modname.

applid TIME-OF-DAY CLOCK DIFFERENCE IS AT LEAST sss SECONDS.
Explanation:

This is an informational message issued from the CICS TCB. Active CICS and alternate CICS systems are executing on different CECs, and the time-of-day clock on the alternate CEC is earlier than that on the active CEC. If takeover occurs then some CICS processing will have to be delayed until the time-of-day clock on the alternate CEC is later than that on the active CEC. The CAVM has estimated the lower bound to the clock difference and this is at least 15 seconds; the message contains the estimated difference. Note that the lower bound may change as more surveillance signals are processed by the CAVM. This may be the case within the first 3 to 5 surveillance signals of the active CICS starting. An elapsed time of some 10 seconds. This message is repeated as necessary.

System action:

CICS processing continues.

Ensure that the time-of day clocks are synchronized as closely as possible. Note that takeover times may be increased if the difference in values is significant.

If takeover occurs then some CICS processing will have to be delayed until the time-of-day clock on the alternate CEC is later than that on the active CEC. The CAVM has estimated the upper bound to the clock difference and this is at least 15 seconds; the message contains the estimated difference. Note that the upper bound may change as more surveillance signals are processed by the CAVM; message DFHXG6681 will be repeated as necessary.
