The LTM for MVS Use_repdef configuration parameter controls whether the Replication Agent sends Log Transfer Language (LTL) that contains only the columns specified in a replication definition, or all of the columns in the IBM DB2 Universal Database primary table.
When the value of the Use_repdef parameter is set to N, the Replication Agent sends LTL with data for all of the columns in the IBM DB2 Universal Database primary table. When the value of the Use_repdef parameter is set to Y, the Replication Agent sends LTL with data for only the columns specified in the replication definition.
By sending data for only the columns needed for the replication definition, network traffic is reduced, which can improve performance.
If you set the value of Use_repdef to Y, you can use other LTM for MVS parameters, such as Minimal_cols and Suppress_col_names, to enhance Replication Agent performance. See the Replication Agent for DB2 UDB Installation Guide for more information.
