Distributing Application Loads Advanced replication is useful for transaction processing applications that require multiple points of access to database information for the purposes of distributing a heavy application load, ensuring continuous availability, or providing more localized data access. Applications that have such requirements commonly include customer service oriented applications. Information Transport Advanced replication can be useful as an information transport mechanism. Advanced Replication Configurations Oracle supports the requirements of advanced replication environments using multimaster replication as well as snapshot sites. Multimaster Replication Oracle's multimaster replication allows multiple sites, acting as equal peers, to manage groups of replicated database objects.
Applications can update any replicated table at any site in a multimaster configuration.
The following figure illustrates a multimaster advanced replication system.
