Systems, methods and computer program products for DDL replication are described herein. An embodiment includes a replication agent to instantiate one or more DDL triggers in a primary database and a replication server to provide DDL command text to a replicate database based on said DDL triggers. The replication agent uses the DDL trigger(s) to capture one or more DDL events and retrieve a transaction log associated with the DDL events. The replication agent processes the transaction log to obtain DDL command text. The DDL command text is then sent to a replicate database by the replication server where it is executed in an appropriate user context. In this way, DDL commands in may be replicated using DDL trigger(s) and session context switching.
