Advanced replication data synchronization statements let you perform such tasks as registering replica databases, implementing access rights, and creating publications. In addition, you administer the advanced replication functionality using many of these statements. For example, you use MESSAGE commands to create and manage synchronization messages and DROP commands to remove synchronization objects such as publications and subscriptions.
The advanced replication statements are grouped into the following categories and their usage is described in this section. See solidDB® SQL Guide for an alphabetical list of all SQL statements, including those used in advanced replication operations.
