PM65873: OBJECT COMPARE APPENDS REBUILD INDEX FOLLOWING TABLE UNLOAD / DROP / CREATE / LOAD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In DB2 Object Compare Tool for z/OS customer reports that when a
  table is involved in a DROP / CREATE scenario and there is an
  INDEX defined on that table, then OC generates a REBUILD INDEX
  utility that follows the LOAD of that table. Customer complains
  that the REBUILD INDEX is redundant as the LOAD utility performs
  that function.
  .
  Customer reports INDEX uses DEFER YES and would prefer to see OC
  APPLY job without REBUILD INDEX utility included.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of the DB2 Object Comparison Tool for  *
  *                 z/OS who compare indexes between target and  *
  *                 source with the 'Run REORG/REBUILD' option   *
  *                 set to 'Mandatory' or 'All relevant' on      *
  *                 panel GOC5 'Generate Compare Jobs'.          *
  ****************************************************************
  * PROBLEM DESCRIPTION: In the DB2 Object Comparison Tool for   *
  *                      z/OS, when the 'Run REORG/REBUILD'      *
  *                      option on panel GOC5 'Generate          *
  *                      Compare Jobs' is set to 'Mandatory'     *
  *                      or 'All relevant', the tool will        *
  *                      generate the needed REBUILD INDEX       *
  *                      utility in the APPLY job to make the    *
  *                      target indexes operational after        *
  *                      applying the changes from the           *
  *                      comparison. When the table the index    *
  *                      is created on is dropped and            *
  *                      recreated while applying the            *
  *                      changes, and the LOAD utility is        *
  *                      executed to RELOAD the table,           *
  *                      then the REBUILD INDEX utility          *
  *                      should be ignored because the           *
  *                      LOAD utility will rebuild all the       *
  *                      indexes of the table. However,          *
  *                      the DB2 Object Comparison Tool          *
  *                      still generates the REBUILD INDEX       *
  *                      utility in some cases, which is         *
  *                      unnecessary and redundant.              *
  *                                                              *
  *                      One example is when the index           *
  *                      is dropped and recreated with the       *
  *                      DEFER YES option specified, the         *
  *                      index could be put into REBUILD         *
  *                      pending status after it is recreated.   *
  *                      A REBUILD INDEX utility is needed       *
  *                      to remove the pending condition.        *
  *                      When the 'Run REORG/REBUILD' option     *
  *                      on panel GOC5 'Generate Compare Jobs'   *
  *                      is set to 'Mandatory' or 'All           *
  *                      relevant', Object Compare will always   *
  *                      generate the REBUILD INDEX utility for  *
  *                      the index.  However, in the case when   *
  *                      the table the index is created on is    *
  *                      dropped and recreated, and the LOAD     *
  *                      utility is executed to RELOAD the       *
  *                      table, the REBUILD INDEX utility        *
  *                      should be omitted because LOAD WILL     *
  *                      rebuild all the indexes of the table.   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The DB2 Object Comparison Tool for z/OS generates an unnecessary
  REBUILD INDEX statement that follows the LOAD utility of the
  table the index is created on. The REBUILD INDEX statement is
  redundant in this case, as the LOAD utility will rebuild all the
  indexes of the table.
