StarQuest Data Replicator Plus for DB2 UDB v3.73 Release Notes

September 2011


StarQuest Data Replicator (SQDR) is a replication software product that allows you to copy data between IBM DB2, Oracle, MySQL, Informix, and Microsoft SQL Server database environments.

The base StarQuest Data Replicator software runs on Windows and provides full refresh replication, which copies all the source data that you specify for replication, regardless of when that data was last replicated. This provides a “snapshot” of the specified source data at the time of replication.

SQDR Plus for DB2 UDB is a separately licensed component that provides incremental replication support for SQDR users. Incremental replications copy only the data that has changed, reducing the amount of data that is transferred and allowing the replication to occur more frequently.

SQDR Plus for DB2 UDB also provides the following advanced features:

The following topics are addressed in these Release Notes. Refer to the appropriate SQDR Plus Quick Start Guide at for detailed information about installing StarQuest Data Replicator Plus for DB2 UDB for the first time. The SQDR Plus Quick Start Guides include instructions for installing both SQDR and SQDR Plus. Refer to the SQDR Plus for DB2 UDB Users Guide for detailed information about using the StarQuest Data Replicator Plus for DB2 UDB software.
