With the introduction of heterogeneous datatype support (HDS) in Replication Server version 12.0, the create connection command’s dsi_sql_data_style parameter is now invalid.
The create connection command’s dsi_sql_data_style parameter was used in earlier versions of Replication Server to provide some data translations for the DB2 UDB for z/OS replicate database. Do not use this parameter with Replication Server version 12.0 or later. The default setting should be " "(blank space).
