Connect to an Oracle 8i database using a 10g client

Question

I recently upgraded my oracle client to 10g (10.2.0.1.0).

Now when I try to connect to a legacy 8.0 database, I get

ORA-03134: Connections to this server version are no longer supported.

Is there any workaround for this problem, or do I have to install two clients on my local machine?

Answer 1

I had to connect a C# code to an Oracle 7 (I know you it's 8...)... the only way I get it was to get the CD to install the Oracle Server and to go in the "Optional Configuration Component" and to use the Oracle73 Ver2.5.

I think you should go check the CD of the Oracle 8 Server and check if an ODBC is still available.

Answer 2

Yes, you can connect to an Oracle 8i database with the 10g client, but the 8i Database requires the 8.1.7.3 patchset, which you can get from Oracle's Metalink support site (requires login).

Here's an Oracle forum post with the details.

If updating your Oracle Database isn't an option, then you can have 2 different clients installed (in different "Oracle Homes" (or directories), and use the selecthome.bat file to switch between your installed clients.

For example, before connecting to 8i, you'd run:

C:\Oracle\Client1_8i\bin\selecthome.bat

or this to use your Oracle 10g client:

C:\Oracle\Client2_10g\bin\selecthome.bat

Answer 3

i can not found selecthome.bat file in oracle8i/bin which i found on oracle10g..

So ,please clear this thing
