ETL Oracle Connection error ORA-01017: invalid username/password;

Question

I am testing my oracle connecting on ETL but getting this odd error: ORA-01017: invalid username/password; I am 100% sure my credentials are correct, as it works on SQL Developer.

More Details:

Error at <Package_name> [Connection manager "OracleSource"]: OCI error encountered. ORA-01017: invalid username/password; logon denied
Error HRESULT E_FAIL has been returned from a call to a COM component. (Microsoft.SqlServer.DTSRuntimeWrap)

Answer 1

Check the case of the password. A password with the wrong case may work in some clients but fail in others.

Ancient versions of Oracle SQL Developer may use the case-insensitive Oracle 10g password hash algorithm (3DES?). If your ETL tool has a more modern Oracle client it will use the case-sensitive 11g (SHA?) or 12c (PBKDF?) hashes.
