Application does not open up in 10g client

[rajsesh]

We have an application developed using Delphi and Oracle. We still use the DOA (Direct Oracle Access) component of version 3.4.
We were trying to work using 10.1.0.2 oracle client and 10.1.0.4 server.
The application does not open and an oracle error "Initialization Error. SQL*Net not properly installed. OracleHomeKey: SOFTWARE\ORACLE OracleHomeDir: " is thrown.
However all the 10g client installation are perfect in that machine and registry values corresponding to previous versions have been removed.
We ran our application from a machine with 9i client (the database in the same 10g server) and it worked. It also works in 9i client - 9i server configuration.
Therefore I would like to know whether it is a problem with the old version of DOA. I would like to know whether DOA version 3.4 can support Oracle 10g. Or it is time for us to move to latest versions of DOA

Version 3.4 will indeed not recognize the 10g client (Oracle changed the registry layout). You will need to upgrade to 4.0.

Thanks a lot for the info.
yeah, now it is the daunting task of getting approval from my management team to buy the latest version
Once again thanks a lot

Hi.
we have the same problem of rajsesh user.

We developed a Delphi 6 application with DOA 4.0.3.
Until now we worked fine with the following combinations:

8i Server / 8i Client
9i Server / 9i Client
8i Server / 9i Client

Now we're testing Oracle 10g Express, but when we run the application from the Oracle 10g Express Server we get this error:

"Initialization Error. SQL*Net not properly installed. OracleHomeKey: SOFTWARE\ORACLE OracleHomeDir: "

Why are we getting this error? We are using the DOA 4.0.3, so it should work.

Best regards.

Can you export the registry section hkey_local_machine\software\oracle and send it to me?
