Replication Intrusions and Impacts in Oracle

The performance and operation of Oracle primary data servers may be affected if a Sybase replication system is incorporated.

While the Replication Agent reads the Oracle online and archive redo logs to retrieve transaction information, it does require a specific log configuration. To provide and maintain the necessary information, enable these items in Oracle:

Archiving of redo logs
Supplemental logging of primary key and unique index data

In addition, the Replication Agent must have direct access to the Oracle redo logs and Replication Agent must run on the same platform as the primary Oracle server.
