IJ34945: THE TIME FOR AN RTEMS TO COMPLETE A STAGE2 OPERATION IS EXCESSIVELY LONG.

IBM Tivoli Monitoring 6.3.0 Fix Pack 7 Service Pack 9 (6.3.0.7-TIV-ITM-SP0009)

APAR status

• Closed as program error.

Error description

• In ITM v630 FP7 SP2, APAR IJ16040 (OA57107) optimized the
  utilization of memory when the RTEMS performs a Stage2
  operation;
     (i.e. a re-synchronization of its tables with those at the
  Hub).
     When the size of the Access List is large, (i.e. >100k
  records), the additional time to optimize memory utilization
  adds appreciably to the overall time of the Stage2.
  

Local fix

• An alternative approach to reduce the memory utilization during
  a Stage2 has been implemented that doesn't increase the duration
  of process.
  

Problem summary

  The time for an RTEMS to complete a Stage2 operation is
  excessively long
  

Problem conclusion

• An alternative approach to reduce the memory utilisation during
  a Stage2 has been implemented that doesn't increase the duration
   of process.
