Fix – SSIS to Oracle connectivity issue during run time (Error code: 0x8007007E/0xC0202009)


Blog for reference - Vijred

SSIS package started failing when I execute the package though all validations are successful. The failure was related to oracle connection failure.

I had to change the package to Execute in 32 bit to fix the connectivity failure.


Change Run64BitRuntime value from True to False:

Actual Error Code fore reference:
