Create a Replication Server function-string class, which is a named collection of function strings used with a specified database connection. Function-string classes include those provided with Replication Server and those you create. The system-provided function-string classes are rs_sqlserver_function_class, rs_default_function_class, and rs_db2_function_class.
Make sure the Replication Server is running. Create and establish a connection to the server.
