ORA--03134:Connections to this server version are not supported.

[r-a-v-i]

Hi,
I am using PL/SQL Developer-7.1.4.1390.

I have recently installed the Oracle 11g on my localhost. I was able to access a remote data base Oracle - 8.1.7. After installing Oracle 11g on my localhost, when I use PL/Sql developer to connect to the remote database, I am getting the following error :

ORA--03134:Connections to this server version are not supported.

Please advise how to get around this problem.

Thanks,

This is Oracle client error: 11g client software does not support connections to 8i databases (and it has limited support for 9i databases afaik.) You should use an older Oracle client software to connect to 8i (9.2 is known to work stable with targets in 8i-10g range.) If you already have an older client installed, you can either set ORACLE_HOME variable in your environment to point to it, or use PL/SQL Developer's Tools|Preferences|Connections configuration page and select proper Oracle Home on that page in the dropdown input field "Oracle Home (empty is autodetect)", or both.
