PI87085: DOWNLEVEL DETECTION ON CATALOG TABLES AFTER ENFM MIGRATION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• V11 IVP job issues down-level detection on DB2 catalog table
  spaces with wrong EXPECTED LEVEL ID. SYSLGRNX contains bad entry
  with START RBA value ending with x001F and END RBA value having
  xA3 in the front of the correct RBA value, which caused DLD at
  the following IVP job that accesses the table in question.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DB2 11 for z/OS users of the DSNTIJEN    *
  *                 ENFM processing job.                         *
  ****************************************************************
  * PROBLEM DESCRIPTION: Down-level detection message DSNB232I   *
  *                      is issued for several catalog table     *
  *                      spaces after the V11 DSNTIJEN ENFM job  *
  *                      step ENFM0027 completes processing      *
  *                      directory table space DSNDB01.SYSLGRNX. *
  ****************************************************************
  * RECOMMENDATION: Apply corrective PTF when available          *
  ****************************************************************
  During the DB2 11 for z/OS ENFM process (DSNTIJEN job) the
  DSNDB01.SYSLGRNX directory table space is processed in step
  ENFM0027. ENFM0027 is a REORG with SHRLEVEL CHANGE. During
  the REORG LOG phase, UPDATE log records that are processed
  might be incorrectly manipulated which can result in invalid
  START_RBA and STOP_RBA columns values in DSNDB01.SYSLGRNX.
  
  The UPDATE log records being applied during the REORG LOG phase
  reflect changes being made to the STOP_RBA column values in
  DSNDB01.SYSLGRNX.
  
  If the START_RBA and STOP_RBA are changed incorrectly then
  this can cause the reported down-level detection problems.
  The down-level detection errors reported are false, the data
  in the table spaces is valid. The invalid START_RBA and
  STOP_RBA column values could also impact the ability to recover
  the objects whose values were broken.
  

Problem conclusion

• DB2 11 for z/OS ENFM code has been changed to correct the
  problem that can result in damaged START_RBA and STOP_RBA
  columns values in the DSNDB01.SYSLGRNX directory table.
