Backing up and Restoring/Recovering an Oracle 9i Database [message #239795]

I am fairly new at this and have been tasked with managing off site backups for customer data on a 9i database.

I am carrying out a user managed backup of the following data files to the offsite data centre.

User File
USERS01.DBF

Control File
CONTROL01.CTL

Redo Log Files
REDO01.LOG
REDO02.LOG
REDO03.LOG

Index File
INDX01.DBF

SPFile
SPFILEBCS.ORA

To test the success of the back up I have created a fresh install of 9i on a new machine with the file structure replicating that of the original.

My questions are;
1) Are these all the files required to be backed up in order to carry out a restore?
2) What are the steps that I need to carry out to restore/recover the database using the above files?

Any help or ‘user friendly’ resources for beginners would be greatly appreciated

Regards
Toby

You just simply replace all the files with these files and at the same location??

wheres your system tablespace file..

how many controlfiles you defined in pfile,if there are more than 1 than place the copy of this controlfile with that name.

Hi,

1) Are these all the files required to be backed up in order to carry out a restore?
Yes, All files according your source database.

1.select name from v$datafile;
2.select name from v$controlfile;
3.select member from v$logfile;
4.spfile or pfile

Above all file need to restore/recover/test your source database backup.

2) What are the steps that I need to carry out to restore/recover the database using the above files?

Thanks Mo

Your blog article is REALLY helpful! Kudos! Much better than the oracle documentation on user-managed backup and recovery

I'm still working through, but have made great progress thanks to you. Once again, Thanks!!

No at all.

For short answer you can reference my blog but in detail you have to look for Oracle Documentation.

I agree with your comment that you can't beat the more comprehensive documentation, but your blog is very useful for someone like myself with very little experience in this area.

So referring back to your blog, I have sucessfully followed it up to step 6. I am now stumped by a problem with step 7 (opening the database), When using the command alter database open it returns the following

ERROR at line 1:
ORA-01157: cannot identify/lock data file 3 - see DBWR trace file
ORA-01110: data file 3: 'O:\BCS\INDX3.ORA'

I have tried locating the DBWR trace file, but have had no luck. Is it somewhere in the oraclehome directory under a different name?

Any help or thoughts you have on this would be greatly appreciated.

Regards
Toby
