Oracle Connector For SSIS


We are migrating our SQL Server to 2021. We currently use the Antiunity driver which can no longer be used with latest version of SQL and SSIS.

When we tried to use the "Microsoft Connector for Oracle" the source spooling is very slow and not on par to the Antiunity driver's performance.

Kindly advise if there any known issues related to the performance using "Microsoft Connector for Oracle" with Oracle 19C

    Hi @Rajagopalan, Ganesh : Functions Technology,

    We are migrating our SQL Server to 2021

    You are probably using SQL Server 2022.

    "Microsoft Connector for Oracle" is very performant.

    Behind the scenes Microsoft is using one of the best ODBC drivers on the planet that Microsoft licensed from a reputable vendor. You can see it in the Control Panel => Administrative Tools => ODBC Data Sources

    Hi @Rajagopalan, Ganesh : Functions Technology,

    You may also raise the issue to SSIS project team which will help to check if there is performance issue.

    And like Yitzhak said, you may use ODBC for a try.
