Replication Server 15.5 extends the scope of the none parameter to apply to all functions, and provides the flexibility to identify which function strings Replication Server can avoid executing on replicate databases.
In versions earlier than 15.5, the none parameter of the alter function string and create function string commands applies only to the rs_writetext function, and instructs Replication Server not to replicate a text, unitext, or image column value.
Use the none parameter to identify class-level and table-level function strings that do not have output commands. Replication Server does not execute these function strings on replicate databases.
See “Using output templates” in Chapter 2, “Customizing Database Operations” in the Replication Server Administration Guide Volume 2.
There is no change in the syntax of the alter function string and create function string commands. See Chapter 3, “Replication Server Commands” in the Replication Server Reference Manual.
