Hi,

after moving to an new oracle19 machine one of our customers gets an Access violation at address 7364A074 in module 'oranls19.dll'. read of address 00000004.
We are using delphi xe2 and Direct Oracle Access 4.1.3.1 in an windows service.

At startup we test connecting to oracle, connecting works, we do some tests.
When we try to disconnect using OracleSession.Logoff; the accessviolation occurs.

Any idea were to look at?

Kind regards

Ruud

I'm not sure what could cause this. Does this error only happen when running as a service? Or does it also happen during an interactive session? If it only happens for the service you may want to check the Oracle environment for the service user account.

Hi Marco.

i tried to make an interactive session but that application crashes immediately but mentions an other dll:

Does a sqlplus.exe work correctly?

Hi Marco,


i will ask them to verify correct working of sqlplus.exe. But i know an other delhi/direct oracle access service running in the same use account works correctly

.kind regards
