1. Install the Oracle7 Server for Windows NT
Install the Oracle7 Server for Windows NT. During installation, you
will have the choice of installing the starter database. If you do not
need another Release 7.3 database (in addition to the one that you
are upgrading from 7.0/7.1/7.2), you do not need to install the
starter database.
Additional Information: See Installation for installation steps
and options.
2. Add an ORACLE_SID key to the NT registry
a. Create a SID for the to–be–migrated database instance.
For example, choose ABCD as the SID.
Note: If you have chosen to install the starter database during
Release 7.3 installation, Do not use ORCL as the SID (the
starter Release 7.3 database has ORCL as the default SID).
Change the ORACLE_SID from ORCL to ABCD.
Note: SID is limited to four alphanumeric characters or less.
b. Run regedt32.exe in line mode.
c. Go to \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE.
