Techniques for peer-to-peer replication of objects in a relational database

摘要

Techniques for replicating a database object of a relational database managed by a database system from a first node on a network to a second node on the network include determining that the database object on the first node includes a user-defined object. A first routine of the database system is invoked. The first routine performs the step of copying the database object to the second node of the network. The first routine copies a name of a user-defined defined type of the user-defined object from the first node to the second node. The first routine also copies a first definition of the user-defined type from the first node to the second node. The first routine then copies a second definition of the database object from the first node to the second node. The second definition includes the name of the user-defined type. These techniques provide the benefits of peer-to-peer replication in a distributed database to users of object-relational databases that including user-defined objects.
