00C90D01

Your data set is not recognized as an IBM MQ page set. This may be for one of the following reasons.

The data set has not been formatted
You are attempting to backwards migrate from a newer version of IBM MQ to an older version of IBM MQ without first running START QMGR BACKMIG(target-vrm) at the newer version of IBM MQ.

System action

The current execution unit terminates with completion code X'5C6', and a dump is produced.

System programmer response

Investigate the reason code and take one of the following actions:

Format the page set
Run START QMGR BACKMIG(target-vrm) at the newer version of IBM MQ before performing the backwards migration
Start the queue manager with the correct level of code

00C90D02

This reason code is caused by one of the following:

An attempt to use a page set that is a valid IBM MQ page set, but does not belong to this queue manager
An attempt to change the subsystem name

Neither of these actions is allowed.

System action

The current execution unit terminates with completion code X'5C6', and a dump is produced.

System action: The current execution unit terminates with completion code X'5C6', and a dump is produced.
System programmer response: Collect the items listed in Diagnostics and contact the IBM support center.

00C91400

The data manager was unable to access the header page (page 0) of one of the page sets.

System action

The current execution unit terminates with completion code X'5C6', and a dump is produced. The number of the page set with a header page that was unreadable is held in register 2.

System programmer response

Check for a preceding IEC161I, CSQP060E, or CSQP011E message relating to page set mentioned in register 2.
Check the following:
- For the page set mentioned in register 2, is the appropriate CSQPnnnn DD statement present in the started task JCL procedure for the queue manager, xxxxMSTR?
- Does this DD statement reference a genuine data set? DD DUMMY statements are not allowed for page sets.
- Is DEFINE PSID(nn) present in the CSQINP1 initialization input data set?
If we are still unable to resolve the problem, collect the items listed in Diagnostics and contact the IBM support center.

00C93500

IBM MQ was extending a page set at startup, based on log records from earlier dynamic page set extend operations. (IBM MQ does this so that any media recovery operation will have the required number of pages available in the page set.)

The page set could not be extended to the required RBA value.

The contents of the relevant registers are as follows:

R0: The number of the page set that could no longer be extended
R2: The logged page number that IBM MQ was trying to extend to
R3: The high page number at restart. This is the base from which IBM MQ was extending.

System action

The current execution unit terminates with completion code X'5C6', and a dump is produced.

System programmer response

Create a larger page set, using multiple disk volumes if required, with a larger secondary extent value. The high page number of the page set should at least match that shown in register 2 in the dump.

00C93700

A page set that has been the subject of the RESETPAGE function had not previously been through a clean shutdown of the queue manager. Using this page set for subsequent IBM MQ processing would lead to data integrity problems.

System action

The current execution unit terminates with completion code X'5C6', and a dump is produced.

System programmer response

Check the page sets that are defined to the queue manager. One or more of the page sets has been the subject of a RESETPAGE operation. Do not run the RESETPAGE operation against page sets that are either of the following:

Fuzzy page set backups
From a queue manager that has terminated abnormally

If we are unable to solve the problem, collect the items listed in Diagnostics and contact the IBM support center.

00C94505

An internal error has occurred.

An attempt to restart with a log from another queue manager was detected. The queue sharing group name recorded in the log during checkpoint does not match the name of the queue sharing group in the queue manager using that log. If the correct log is being used, we can perform the change only after a clean shutdown of the queue manager, that is, after a quiesce.

Message CSQI060E is issued before this error occurs.

System action

Restart is terminated abnormally with completion code X'5C6' and a dump is produced.

System programmer response

Restart the queue manager using the correct logs and BSDS, or change the QSGDATA system parameter. Note that we cannot change the name of the queue sharing group that a queue manager uses unless it has been shut down normally.

The following registers in the dump contain helpful values:

R0 = the queue sharing group name recorded in the log
R2 = the queue sharing group name in the running queue manager

00C94506

An internal error has occurred.

An attempt to restart with a log from another queue manager was detected. The shared queue manager identifier recorded in the log during checkpoint does not match the shared queue manager identifier in the queue manager using that log. If the correct log is being used, the entry in the Db2 CSQ.ADMIN_B_QMGR table for this queue manager has been corrupted.

Message CSQI061E is issued before this error occurs.

System action

Restart is terminated abnormally with completion code X'5C6' and a dump is produced.

System programmer response

Restart the queue manager using the correct logs and BSDS. If the correct logs are being used, correct the entry for the queue manager in the Db2 CSQ.ADMIN_B_QMGR table. If we cannot resolve the problem, contact the IBM support center for assistance.

The following registers in the dump contain helpful values:

R0 = the queue manager identifier recorded in the log
R2 = the queue manager identifier in the running queue manager
