Hello,
I have an SSIS package that imports data into a SQL Server 2012 database from an Oracle 11g database (Attunity Connector v2.0 and Oracle 11g client). The Oracle 11g database was upgraded to Oracle 12c (version 12.2). After that, my SSIS package cannot connect to the Oracle 12c database. First, I got error "ORA-28040: No matching authentication protocol". I found a fix for that by having the Oracle DBA add the line "SQLNET.ALLOWED_LOGON_VERSION_SERVER = 11" to sqlnet.ora file on the Oracle server. However, now I am getting error "ORA-01017 invalid username/password; login denied." We have tried re-creating a different Oracle password but no luck.
What are our options? Do we have to install the Oracle 12c client on the SQL Server? I wasn't sure how that would work with the Attunity v2.0 connector.
Thank you in advance.
