I have a oledb source -> oledb destination from Oracle to SQL Server that's been failing since I've upgraded the client from Oracle 11.0.1.7 to 12 with the error "cannot convert between unicode and non-unicode string data types."
I've installed two homes, one with 11, one with 12, because I need 12 on the server to support SSRS 2016. However, 12 is the default, and SSIS seems to be using that one when I run packages because I still get the error. Is there a way via connection string or something to force SSIS to use client 11? I'm trying to avoid having to go into many packages and add transformations or something to deal with this Unicode error, so any advice is very welcome.
