  • Thanks for posting your issue and hopefully someone will answer soon.

    This is an automated bump to increase visibility of your question.

  • Hi if your issue is fixed please post the solution. My first response is validate your tnsnames.ora file. Another thing to check is how connections are made in production.

  • I am using VS 2019 Integration service project. I installed MicrosoftSSISOracleConnectorX64.msi to get the Oracle Source and Destination components. But they are not displayed in my toolbox. Also tried with MicrosoftSSISOracleConnectorX86.msi. No luck.

    I read the Oracle client is NOT needed for OracleConnector component starting 2019 version. Am I missing something? Please suggest how to add the Oracle Source and destination components in SSIS toolbox?

  • Hi, first check and see if you can connect to the Oracle data source using a query tool. Can you do that?

  • Do you have SQL 2019 Enterprise\Developer?  Microsoft connector only works for Enterprise.  Im using Standard and had to use Oracles Latest instant client.

  • Hi, I am able to connect to Oracle data source using SQL developer. I have Visual Studio 2019 Enterprise edition.

    As per I should be able to see Oracle source and destination in DFT toolbox. Attaching my project Data flow task toolbox screenshot where I don't find Oracle source and destination in "Common" toolbox list.

    I have installed MicrosoftSSISOracleConnector.
