We have a Delphi 5 Windows application that uses DOA 4.1.1 to connect to an Oracle 12c server using an Oracle 12.1 client.

With this configuration, we keep getting some random access violation errors in module 'orageneric12.dll'.

With the same Delphi 5 application and still using DOA 4.1.1, we are NOT getting any errors when using an Oracle 10.2 client connection to the same Oracle 12c server.

Can you please tell me if DOA 4.1.1 for Delphi 5 officially support an Oracle 12.1 client ? If it supports it, do you have any clue for these exceptions.

Thanks,

Michel W.
