StarQuest Data Replicator Plus v5.24 Release Notes

August 2021


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 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 also provides the following advanced features:

The following topics are addressed in these Release Notes. Refer to SQDR Plus Quick Start Guide for detailed information about installing StarQuest Data Replicator Plus for the first time. The SQDR Plus Quick Start Guides include instructions for installing both SQDR and SQDR Plus. Refer to the SQDR Control Center (SQDR Manager) Online Help for detailed information about using the StarQuest Data Replicator Plus software.

System Requirements

You can install and run the StarQuest Data Replicator Plus on computers running the following software:

You can replicate data from the following source database systems:

IBM Db2 LUW 11.5.5 (bundled with SQDR Plus) is installed on the computer running SQDR Plus for use as a control database and temporary store; it can also be used as the control database for SQDR.

SQDR Plus requires Visual C++ 2015/2017/2019 runtimes on Windows. The SQDR Plus installer will install the Microsoft-supplied Microsoft Visual C++ 2015/2017/2019 Redistributable package if it is not already present on the system. The Microsoft Redistributable package will remain on the system if SQDR Plus is upgraded or uninstalled.

SQDR Plus is managed using a browser and SQDR Control Center. The following browsers are supported:
