Problem summary

• ****************************************************************
  * USERS AFFECTED: DB2 users using more than 25 buffer pools    *
  *                 and IFCID 2 overflow trace records with      *
  *                 UK94096 or UK95295 applied.                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: An IFCID 2 overflow trace record        *
  *                      contains an incorrect record length     *
  *                      due to a missing recompile of a module  *
  *                      that sets the record length.            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When more than 25 buffer pools are allocated, an IFCID 2
  overflow trace record contains an incorrect record length.
  The incorrect length impacts the buffer pool statistic mapping
  starting from the 26th buffer pool and beyond and causes an
  incorrect count to appear in the Statistics report.
  

Problem conclusion

• DB2 has been fixed to recompile a module that stores the
  length of an IFCID 2 overflow trace record.
  

Temporary fix
