Re: Problem upgrading from Windows 2000 Oracle 8.0.6 to Oracle 9.2.0.1.0

You likely need to investigate the 9.2 tnsnames.ora file.  It probably
needs to be modified to include the 8.0.6 database information.

The DBCA is getting the info from the registry, but that doesn't help
you with creating a database connection.

Problem upgrading from Windows 2000 Oracle 8.0.6 to Oracle 9.2.0.1.0





Hi everybody,

I've just installed Oracle 9.2.0.1.0 onto a Windows 2000 server which was currently running Oracle 8.0.6 with a single instance on it. I noticed that during the installation, I wasn't presented with the Upgrading An Existing Database screen. This may be significant! I didn't think anything of it, since I intended to run the Database Upgrade Assistant independently after installing 9.2.

The installation went smoothly. I then checked that the 8.0.6 db instance was still up and running, by connecting to it from my office workstation. Yes, fine. Back to the server, and I fired up Database Upgrade Assistant from the Oracle 9.2 program group. After the Welcome screen it showed the panel which did indeed list my 8.0.6 database. I selected it, gave a userid with the necessary SYSDBA privileges, and a password, and clicked on next. Then I got an error message: ORA-12203: TNS unable to connect to destination.

Now, presumably this means I've got something wrongly configured on the server, such that it can't connect to its own local database. Any ideas at all, as to where I should start looking, would be very greatly appreciated!

Best regards,
