Hi @Divyesh Patel ,
(1) What is your SSIS run-time SQL Server version?
Please issue the following statement and add it to your question:
SELECT @@VERSION;
(2) Also, how do you execute a SSIS package:
- From the SSISDB Catalog.?
- From the SQL Server Agent Job?
(3) Try to change the runtime execution mode between 32-bit and 64-bit.
UPDATE
If you have SQL Server 2019 with SSIS, Enterprise edition, it is much better to use Microsoft Connector for Oracle. Here is the link: Microsoft Connector for Oracle
It is pretty good, and even doesn't require Oracle Client installation.
