Steps for migrating from 7.1.6 on Unix to 8i on Windows

I have Oracle 7.1.6 installed on SCO Unix 5.0.5. Now we are switching over to Oracle8i (8.1.7) on Windows 2000/2003 Server. I would like you to give the steps for migrating from Unix to a Windows environment.

I have Oracle 7.1.6 installed on SCO Unix 5.0.5. Now we are switching over to Oracle8i (8.1.7) on Windows 2000/2003 Server. I would like you to give the steps for migrating from Unix to a Windows environment.

I tried this once by taking a full export on Unix and copying the export file to my Windows environment (via FTP in binary format). I created the database in 8.1.7 with the users that were in the Unix database. As well, I had created the tablespace by the same names, but when I imported I was partially able to import the database. The relations were not established between the tables, and also I am not able to delete this database as it asks me for a password for the internal account. I do not have the password for the internal account in my Unix database. Is there something missing in these steps?

If you are migrating your database to a different operating system, you are limited to using the export/import method, unless you are migrating to 10g. In this case, you would have the option of using transportable tablespaces across different platforms. According to the Oracle8i Migration Release 3 (8.1.7) Guide available on Oracle's Technology Network Web site, your database must be at version 7.3 before a direct migration to Oracle 8.1.7 is supported. This, however, assumes that you will remain on the same operating system, which is not the case here.

Without specific error messages or more information, I cannot provide further assistance with the import problem you have encountered. I would suggest trying it again since it looks like you followed the correct procedure.

With respect to your problem where you are being asked for a password when connecting internal, I suspect the init.ora parameter REMOTE_LOGIN_PASSWORDFILE is set to either SHARED or EXCLUSIVE. From your problem description, it sounds like you are logging into the database remotely, i.e., from another server, which explains the prompt for a password. If so, log in to the server locally with a userid that belongs to the DBA group. OS authentication overrides password file authentication so you should not be asked for a password.
