It seems you did'nt install the Oracle client on your PC.
After that a listener should be configured.


ps A nice tool to manage Oracle is Toad (see Quest Software)

Check the registry see if the oracle client is there.
Check the PATH variable to see if the oracle client is there, WEBDEV needs to know where is the oracle client.
In one of my servers( win 2k server) i had the same problem . After the installation of all the programs (WEBDEV,ORACLE NET and native access) WEBDEV still doesn't work and one restart of the server solve the problem.
you only need oracle net not all the oracle client to work with WEBDEV/WINDEV.
I'm using oracle 11g, i don't know if with other oracle version it is the same.

hayyyyyyyyyyy,its my 3 days nows troubleshooting for this issue, till now still not working at all :-( , very very very tiring...

Can you access Oracle via another tool ?
Via SQLPlus f.i. ? This should be installed together with Oracle automaticly.
If you cannot connect to a DB via SQLPlus, perhaps the listener is not configured well.

Hi leo,
I can access it through TOAD, sqlplus, and .net visual studio,...the listener is working well, but the error still comes....that error is strange to me..till today still not yet solved...if i run it in webdev server engine, that errors will come..on the same machine on which the webdev server is installed the SQLPLUS,TOAD is working fine... something is missing here i really don't know .. :-( :-( :-(

Hi Mate,

You are using the Native driver if i read this correctly? Could you try using OLE DB just as a test?

Also, what client OS are you using? If you're using Vista try running Webdev in administrator mode just to be on the safe side.

A problem i had before with webdev is the context in which the app server runs. .NET uses a different policy, so my ASP.NET apps worked a charm, but webdev didnt on Oracle 9i. How do you authenticate to Oracle, ie. password or integrated?

What I had to do was changing the context in which the webdev app server runs, ie, give it a domain account to run under. Note that this was for OLE DB, so your case could be different. But again, this was with Vista Ultimate to a Win2003 server DB.

Have you been able to sort this native acces to Oracle using WebDev? I am also pulling-out my hair

von David Stevens - am 15.11.2012 13:28

Try something like this as below:

type in

PORT=1521;WD CLIENT LIBRARY=c:\oracle\product\11.1.0\client_2\BIN\ociw32.dll

in "Extend information: box
wdSql > Connection Wizard > Advanced button

p.s. you must locate exact path and wdSql.exe is in 32-bit
oci.dll should be in 64-bit
