Altering Database Connections

Use SAP Control Center or alter connection to change the attributes of a database connection at the Replication Server where the connection was created.

1. Use suspend connection to suspend activity on the connection.
2. Execute the alter connection command with the relevant parameters.
   Note: Using the set log transfer off clause for the alter connection command drops the RepAgent connection from a primary site. Before using this clause, be sure there are no replication definitions defined for data in the database.
3. Use resume connection to resume activity on the connection.

• Suspend Database Connections
  You must suspend a database connection before you alter it or when you remove a data server from service for maintenance.
• Set and Change Parameters Affecting Physical Connections
  You set configuration parameters for a connection when you create it. Later, you can update those parameters with SAP Control Center, the alter connection command.
• Resume Database Connections
  After you have changed the attributes of a database connection, you can resume activity on the connection either in SAP Control Center or by using the resume connection command.
• Changing Replicate Databases to Primary Databases
  Each primary database must have a Replication Agent that scans the database log and transfers data to the Replication Server for distribution to replicate databases. If you want to change an Adaptive Server database that is designated as replicate-only to be a source of replicated functions or to contain primary data, you must enable the RepAgent thread for the database.
• Changing Primary Databases to Replicate Databases
  You can change the primary database to a replicate database.
