recreating oracle from hard drive [message #339427]

One of our older systems had oracle 9i installed on it. The system was shut down a while ago and when we recently tried to restart it, we could not. We are planning to take the drive out of the old sever and copy the information onto a new server, with all the oracle binaries, oracle files as well as the database physical files (ctrl files, datafiles etc). I am not aware of any backups taken. Which alternatives do I have to bring up this oracle database so we can get to the information.

THanks

Code: [Select all] [Show/ hide]

sqlplus
/ as sysdba
startup
exit

If DB starts, you can get old data.
If DB does not start, refer to documented & tested restoration procedures.

OS is windows 2000
Yes we are able to access all folders on the hard drive we plugged in
I am a DBA. We just put the drive so I will try to start it and see if it works and will get back to you

I may be wrong, but I think your best bet might be
1) Install the same version of Oracle on your new box as on the old one.
2) Create a database with the control files in the same locations and with the same names as the old database (get these from the Init.ora file
3) Copy all the datafiles from the old Db into the same locations on the new Db.

You should be able to start this new database up, and it should contain all the data of the old one.

Since this is Windoze, you won't be able to "just start it". Prior to being able to start the database, you'll need to create a Windows service for Oracle with oradim.
