I have developed one SSIS package , which is supposed to load data from sql server to oracle database server. I am using SSDT Visual Studio 2015 and to make connect with oracle from SSIS I had to install "ODAC 12.2c Release 1 and Oracle Developer Tools for Visual Studio (12.2.0.1.1) i.e. ODTwithODAC122011" driver . Earlier using the same driver I used to load data from SQL Server dev environment into my oracle's localhost database server 18C so it was not taking much time to load but now I am supposed to connect to Oracle Development Server 19C . So when I am loading data in Oracle Development Server 19C through SSIS(through data flow task) , its taking hours to load even for a single table which is bit concerning.Is it because of incompatibility issue connecting with Oracle 19c ??
What should I do resolve this issue ??
