DFS0778I xxxxxxxx ERROR eeeeeeee MERGING SIDTABLE FROM MSC SUBSYSTEM yyyyyyyy, ACTION = zzzzzzzz


or

xxxxxxxx MSC SUBSYSTEM yyyyyyyy HAS JOINED/LEFT THE SHARED QUEUES GROUP, ACTION = zzzzzzzz

or

xxxxxxxx ERROR eeeeeeee SENDING/RECEIVING SIDTABLE TO/FROM MSC SUBSYSTEM yyyyyyyy, ACTION = zzzzzzzz

Explanation

This message is produced when the multiple systems communications (MSC) feature is supported in a shared queues group (SQG) environment and one of the following events occurs:
  • An IMS subsystem joins or leaves the shared queues group.
  • An error is detected while sending or receiving the MSC system identification table (SIDTABLE) to or from another IMS while processing an IMS subsystem join or leave.
  • An error is detected while merging a SIDTABLE received from another IMS that has joined the shared queues group.
  • A residual SIDTABLE storage area is being freed that was created from a previous merge of the SIDTABLES when an IMS subsystem joined the shared queues group.
In the message text:
Variable
Meaning
xxxxxxxx
The IMSID of the system that issued the message or detected the error.
yyyyyyyy
The IMSID of the other IMS that joined or left the SQG, or where the SIDTABLE was being sent to or received from, or where the SIDTABLE being merged was sent from.
zzzzzzzz
action code:
ACCEPTED
The event join/leave was accepted
IGNORED
The error was ignored. If receiving a SIDTABLE from another IMS, the received table is not merged with current table. If sending a SIDTABLE to another IMS, the table might not arrive in the other IMS to be processed. If merging a SIDTABLE, one or more SYSIDS in the received table is ignored.
eeeeeeee
Error code produced by the MSC Shared Queues Initialization Routine that detected the error.
Routine
Description
FREEAWSI
Error freeing received SID table storage.
FREEEND
Error freeing storage at end processing.
FREEOSID
Error freeing old SID table storage after merge.
FREEXCFS
Error freeing storage acquired by XCF.
FUNCHIGH
Function value too high.
FUNCZERO
Function not specified.
GETAWSID
Error getting AWE/SID table storage.
GETHLNB
Error getting LNB storage.
GETNSID
Error getting storage or blocks for new SID table.
INITSID
Error initializing SID table.
INVAWECB
ECB in AWE Invalid.

System action

IMS continues processing. If the event was an error, a type 6701-MNZE log record was written to the IMS online log data set. IMS continues processing.

Operator response

If an error was indicated, the join, leave, or merge event might not be completely processed. Have the error corrected and bring the affected IMS subsystems down and back up again (for example, leave and join). If no error is indicated, then this message is informational only.

Programmer response

If the event was an error, this is most likely an error with the MSC configuration, or a system error in the IMS subsystems or MS XCGF facility. Collect the documentation noted under problem determination and call IBM® Software Support.

Problem determination

Record this message and any other DFS0778 messages from both IMS subsystems in the shared queues group identified by the IMSIDS in the messages. Print the 6701-MNZE log records using the DFSERA10 log print utility, from the online log data sets from both IMS subsystems. Take a console memory dump of both IMS subsystems using the z/OS® DUMP command, as soon as possible before any other IMS subsystems join or leave the shared queues group. Save the memory dumps in case they are needed for diagnosis.
