Error description

  • After a flood of IMS messages (DFS2063I and DFS2085I) destined
for the MTO, Sysplex Manager UI address space gets an ABENDC78.
The ABENDC78 is due to a failed CPOOL request because we are
out of storage.  Subpool0 key7 is full of CPOOL CELL POOL
entries.  SM gets a CPOOL entry during the process of logging
the message destined for the MTO.  There were 150,000 messages
to be logged in a 4 minute interval.

Problem summary


    

  • ****************************************************************
* USERS AFFECTED: Users of Sysplex Manager.                    *
****************************************************************
* PROBLEM DESCRIPTION: IMS SYSPLEX MANAGER ABENDC78 in server  *
*                      address space due to  >100K messages    *
*                      queued to be saved in history files.    *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The huge amount of messages can not be served in several seconds
and the CPOOL overflows causing the ABENDSC78

    



Problem conclusion


    

  • The CPOOL overflows because of huge amount of messages
destined to history file on server input queue.
The programs have been changed to stop serving messages if
the not served queue has >2000 messages. This is not an usual
situation - some source of MTO destined messages is in loop.
