Considerations about an Oracle database multi-master replication

In some cases of software-distributed applications, a large data amount must be accessed by a large number of users (dispersed geographically). In these cases, the database replication process provides an efficient solution to increase the application performances. This paper presents two methods to implement a multi-master database replication process. A replication example between two Oracle databases is also described, detailing step by step the operations that must be performed, providing a useful support to solve such problems.
