How to Fix: “MSORA” is not recognized as a valid connection manager type

By | January 7, 2017

Error:

The connection type “MSORA” specified for connection manager “” is not recognized as a valid connection manager type.

This is the most dreaded error while working with Oracle and Attunity and could not find why it would not work even after installing everything that is needed.

Technical Details

It is missing Attunity drivers only. Here is a simple table of which Attunity drivers are needed in order to fix this error

Application Needed Driver Note
Visual Studio 2012 Attunity 2.0 32 bit Visual Studio is a 32 bit application
Visual Studio 2012 Attunity 2.0 64 bit If SSIS Project property > Configuration Properties > Debugging > Run64BitRunTime = true and if SSIS 2012 64 bit runtime is intalled, it needs 64 bit Attunity 2.0
SQL Server Integration Service (SSIS) 2012 – 32 bit Attunity 2.0 32 bit For executing SSIS packages through SQL agent or dtexec.exe
SQL Server Integration Service (SSIS) 2012 – 64 bit Attunity 2.0 64 bit For executing SSIS packages through SQL agent or dtexec.exe
Visual Studio 2014 Attunity 3.0 32 bit Visual Studio is a 32 bit application
Visual Studio 2014 Attunity 3.0 64 bit If SSIS Project property > Configuration Properties > Debugging > Run64BitRunTime = true and if SSIS 2014 64 bit runtime is intalled, it needs 64 bit Attunity 3.0
SQL Server Integration Service (SSIS) 2014 – 32 bit Attunity 3.0 32 bit For executing SSIS packages through SQL agent or dtexec.exe
SQL Server Integration Service (SSIS) 2014 – 64 bit Attunity 3.0 64 bit For executing SSIS packages through SQL agent or dtexec.exe

So if you have a server which has SSIS 2014 64 bit and Visual Studio 2012 then you need to install Attunity 3.0 64 bit and Attunity 2.0 32 bit respectively for SSIS packages to execute through SSIS and Visual Studio
