Oracle Tips  

Oracle MIG utility

1. You must start at 7.3.x (or higher) release level of Oracle. A version 6 database must be migrated to at least 7.3.x before it can be converted to Oracle.

2. Back up the source Oracle database, or perform a complete export.

3. Drop any users or roles named “migrate.”

4. Resolve all pending transactions in a distributed environment.

5. Bring all tablespaces online, or make sure they are offline normal or temporary, not immediate. Resolve any save undo situations in tablespaces (see migration manual).

6. Shut down normal (not immediate or abort).

7. Install the Oracle software. Do not do a “complete” install, as this will attempt to build an Oracle instance and may damage your existing instance beyond recovery. Do a partial, software-only, install.

8. Install the MIG utility into the Oracle7 ORACLE_HOME by using OUI from X-windows on UNIX or its equivalent on your operating system.

9. Unset the TWO_TASK environmental variable on UNIX, or ORA_DFLT_HOLSTER on VMS.

10. Set the following init.ora parameter (or its equivalent location on your system):

ORA_NLS33=$ORACLE_HOME/migrate
