Error description

  • When merge processes partitioned index records with more than
one key column, incorrect data is stored for table partition
records. Additionally, when Source is from a DDL, merge does not
capture the tablespace of the table partition for the index
correctly. This results in ambiguous failures within Object
Compare when the table partition records for the index are read.

Problem summary


    

  • ****************************************************************
* USERS AFFECTED: Users of Db2 Administration Tool for z/OS    *
*                 and Db2 Object Comparison Tool for z/OS      *
****************************************************************
* PROBLEM DESCRIPTION: Object Comparison Tool ambiguously      *
*                      fails when processing partitioned       *
*                      indexes with multiple key columns.      *
****************************************************************
When the merge operation processes partitioned indexes with
multiple key columns, the record information is written
incorrectly in some cases and results in corrupted memory. This
behavior results in ambiguous failures when the corrupted
memory is later read in Object Comparison Tool processing.
