Transporting a database with no archive or backup

Our Oracle 8.0.5.2 sys1orcl.ora file is destructed, but the database works on one computer. We just want to transport the database to another computer. How can we recover it? No archive or backup is available.

Sorry, but if you do not have a backup of the datafile for the SYSTEM tablespace, you will not be able to copy the entire database to another server. About the best that you can hope for is to open up your database and pray that it only needs instance recovery, in which case you can shut down the database and take a good backup of it. See if the following steps work:

  1. svrmgrl (or svrmgr30)
  2. connect internal
  3. startup mount
  4. alter database recover;
  5. alter database open;

If the database opens, you are fine. If the database does not open, then you have lost your database because you do not have a solid backup.
