PK19340: ABEND 106-0C IN OMEGAMON XE PE DATA SERVER WHEN MONITORING MULTIPLE DB2 SUBSYSTEMS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Running the OMEGAMON DB2 Server (Classic O2CI) on an LPAR that
  has 20 DB2 subsystems defined and 12 active results in a large
  number of subtasks running for the DB2PE servers that are
  started as a results of AUTODETECT. Attempts to start additional
  server subtasks or initiate other functions fail due to
  insufficient storage to load modules in to LSQA.

  This may lead to abend878, abenda03 and the O2CI task
  terminating.
  

Local fix

• Locate the OMPEMSTR member, most likely in the RKD2PAR dataset.
  If it is
  not in the RKD2PAR dataset, check the other datasets allocated
  to the
  RKANPAR DD in the step that executes KOBCIRT0
  
  Locate the line that reads
  DB2SSID=(DSN1)
  Change this line to identify the DB2 subssytems to be monitored
  by the
  DB2PE/PM side, for example
  DB2SSID=(DSN1,DSN2,DSN3)
  Add a line to the OMPEMSTR member as follows
  AUTODETECT=NO
  
  This will result in DB2PM/PE data servers only being started for
  the
  selected DB2 subsystems
  
  If during the course of the day it is neccessary to add/remove
  additional DB2 subsystems, modify the OMPEMSTR member as
  indicated above
  to change the DB2 subsys selection, then issue these operator
  commmands
  F o2ci,P PESERVER
  to stop all DB2PE/PM dataservers
  /F o2ci,S PESERVER
  to restart the DB2PM/PE data servers for the new choice of DB2
  subsystems.
  o2ci represents the name of the OMEGAMON DB2 classic address
  space

  ****************************************************************
  When MULTIPLE DB2 SUBSYSTEMS shall be monitored the OMEGAMON XE
  for DB2 PE DATA SERVER starts a monitoring instance for each
  DB2 subsystem. Some load modules will be loaded into storage
  below the 16 MB line. When storage is exhausted and a further
  instance is to be started to monitor an additional DB2 subsystem
  an ABEND 106-0C will occur.
  

Problem conclusion

• Whenever possible the load modules will be loaded into storage
  above the 16MB line.
