Use create connection or alter connection with dsi_quoted_identifier to enable quoted identifier support.
See the Parameters Affecting Database Connections table in alter connection in the Replication Server Reference Manual for the full command description.
Data servers receive quoted identifiers differently. Adaptive Server and Microsoft SQL Server need a special connection set-up for quoted identifiers because they do not expect quoted identifiers. Oracle and UDB do not need a special connection to accept quoted identifiers.
Use admin config to check the value of dsi_quoted_identifier .
