Error description
When doing a source only catalog compare using masks, ignores, and 'Apply mask to ignore fields', Object Compare generates incorrect storage group names for history tablespace when the source is catalog temporal tablespace with related history tablespace, but the history tablespace is not specified for the compare.

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 creates a * * history table space with an invalid * * STOGROUP value when table space * * STOGROUP masks, ignores, and the 'Mask * * Ignored Fields' setting is used. * **************************************************************** If the source is the catalog and includes a temporal table space with an associated history table space, and the history table space is not explicitly selected for Compare, Object Comparison Tool can generate an invalid STOGROUP name for the history table space. This behavior occurs only when all of the following conditions are true: - The table space STOGROUP is included in masks and ignores. - 'Mask Ignored Fields' is enabled. - The source objects do not exist on the target or the comparison is source only.
Problem conclusion
This problem has been fixed.
