Create Database Connections

A connection defines a database to the SAP Replication Server. An SAP Replication Server is designated to manage the database and, if it is a replicate database, to distribute transactions to the database.

The database connection provides SAP Replication Server with:

The name of the data server and database the connection is for
The error class used to process errors returned from the data server
The function-string class to use with the database
The maintenance user login name and password
Information about whether there is an SAP ASE RepAgent thread for the database connection
Options for creating active and standby databases for warm standby applications
Configuration parameters that affect connections

To create:

A standard connection to an SAP ASE database, use rs_init or create connection.
Alternate connections to an SAP ASE database, use create alternate connection. For example, you can create alternate connections to build multiple replication paths. See:
- create alternate connection in Replication Server Commands in the Reference Manual
- Multi-Path Replication in the Administration Guide Volume 2
Connection to a non-SAP database, use create connection with the using profile clause. See create connection using profile in the Reference Manual.

Information Required to Add a Database Connection
You need to specify several items when you add a database connection.
Use the create connection Command
To add a database for a non-ASE data server, use the create connection command with a connection profile specific to your non-ASE data server. To add a database for an Adaptive Server data server, you use SAP Control Center or rs_init, both of which prepare the database for replication.
