Unable to Load dbexpoda.dll

idart · Post by **idart** » Mon 23 May 2005 13:17

Delphi 7, Oracle 10g client, dbExpress 2.50.4 driver.

I have the dbExpress driver for Oracle installed (recently upgraded to 2.50.4, although the problem was there with 2.50.3 as well). I also have the Oracle 10g client installed and I'm using TCRSQLConnection with OCI.DLL.

Whenever I now try to start a program that uses the driver with a TCRSQLConnection, I get "Unable to Load dbexpoda.dll".

dbexpoda.dll is in the installation directory (C:\Program Files\CoreLab\DbxOda) and in System32. The latter is in my PATH. The two are identical and the correct version.

There are no compilation errors or warnings. The error occurs when I set TCRSQLConnection.Connected to True.

Any idea as to what might be going on?

We did not encountered with such problem. Please check, possibly you do not use trial version of DbxOda. Try to specify full path and file name in CRSQLConnection1.LibraryName. Try to use TSQLConnection component. Try to load dbexpoda.dll with LoadLibrary for testing purposes.

- This is not the trial version.
- Specifying full path to dbexpoda.dll and OCI.dll didn't help.
- Switching to TSQLConnection didn't help.
- LoadLibrary() fails.
The resulting Win32 error message is "Invalid access to memory location".

The machine it fails on is a client machine, not my development machine.
Just to be sure, I copied over dbexpoda.dll from a machine where it works
to the client machine, but it didn't help (same error).

BTW: It works with v2.00 of the driver.

We cannot reproduce your problem. Possibly it depends on computer configuration. What version of Windows and service pack do you use?

idart · Post by **idart** » Fri 27 May 2005 08:24

Windows XP, SP2.
It also has various hotfixes installed, but none after April 14th of this year.

In Windows Server 2003 SP1 I got error unable to load dbexpoda.dll. If I remove SP1 then it works fine.
