I am trying to install Oracle Client 32 bit driver and lets see that helps because my database is Oracle 11g.

Hi Nishapd,


it's a long shot... but I had similar problems with the Microsoft ODBC for Oracle driver on a 64-bit Windows 7..
The Microsoft ODBC for Oracle driver didn't work at all, only the OraOLEDB.Oracle and MSDAORA did..
Perhaps you should also try these instead?


Further, I advice you to test the Oracle connection with a simple vbs first (vbs is close enough to classic asp). Be carefull though, you need to be sure to run vbscript in 32-bit mode ! (If I understand Imar, classic asp always runs in 32-bit?)
E.g. if you create a TestMyConnection.vbs and place it on your desktop you would need to start it like %windir%\SysWOW64\wscript.exe C:\Users\Nishapd\Desktop\TestMyConnection.vbs


Hope this helps !

When I change my connection string to,

strConn = "Provider=MSDAORA.1; Data Source=DEV; UID=PORTALDEV; PWD=portaldev"

I am getting below error.

I have 64 bit Oracle client installed with all components on the machine.

Microsoft OLE DB Provider for Oracle error '80004005'

Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed.

/db_open.asp, line 213

Hi Nishapd,


and what does OraOLEDB.Oracle do ?
This one should be included with the Oracle client.



P.s. If you had "Enable 32 Bit Applications" on, I would switch it off again to be sure you are using 64-bit IIS threads. Unless you have 32-bit dll dependencies off course, but then you'll need the 32-bit Oracle client.

I installed 32 bit Oracle client and it's working fine now.

Thanks everyone for helping and spending time for me.
