With a gatewayless connection from Replication Server to DB2 UDB using the Mainframe Connect DirectConnect for z/OS Option, the server_name is the mainframe host name, and the db_name is the name of the replicate DB2 UDB database. The interface file entry for the server_name maps to the mainframe IP address and port.
Gatewayless replication to DB2 UDB for z/OS database requires that you:
Use Mainframe Connect version 15.0 or later.
Define the rs_get_textptr and rs_writetext function strings using the writetext method. See the Replication Server Reference Manual.
Use the rs_xxx_to_db2 (class-level translations for the primary database) Replication Server connection profile.
