A Replication Server database connection name is made up of two parts: a data server name (server_name) and a database name (db_name).
When using the Mainframe Connect DirectConnect for z/OS Option database gateway, the server_name is the name of the database gateway server, and the db_name is the name of the replicate DB2 UDB database.
The replicate Replication Server looks for an interface file entry for the database gateway server_name specified in the Replication Server database connection. The replicate Replication Server logs in to the replicate data server using the user_name and password specified in the database connection.
You must make an entry in the Replication Server interface file to identify the host and port where the Mainframe Connect DirectConnect for z/OS Option database gateway server is listening. The interface file entry name must match the server_name portion of the Replication Server database connection.
