If you are sure that you will not need it again, you may want to drop a function-string class that you created from the replication system. You can drop any function-string class except the three system-provided classes and any user-created class that currently serves as a parent class. Before you can drop a function-string class, you must drop all database connections that use the function-string class, or you can alter the connections to use a different class.
Dropping a function-string class deletes all function strings defined for the class and removes all references to the class from the RSSD.
To drop a function-string class from the isql command line, use the drop function string class command. For example, the following command drops the tokyo_func_class function-string class and all of its function strings:
drop function string class tokyo_func_class
Enter this command in the Replication Server that is the primary site for the class.
Refer to Chapter 3, “Replication Server Commands,” in the Replication Server Reference Manual for more information about drop function string class command.
