I have a cold backup (copy of datafile folder and .dbf ). What are the steps to recovery?

The steps to recovery vary depending on the scenario you are recovering from. The steps to recovery also depend on whether or not you are running in archivelog mode. If you are not running in archivelog mode, then your only recovery option from a cold backup is to shut down the database, replace the control files and datafiles from your backup and start up the database again. You will lose all transactions since the backup was taken.

If you are running in archivelog mode, then you can restore transactions since the backup was taken. Please refer to the Oracle Backup and Recovery Guide for your specific version for more information.

Changing file paths in a recovered Oracle database Expert Brian Peasland helps a reader figure out how to successfully remap the file path for a database that had to be recovered from a dead server.

How to change backup strategy to decrease downtime I am taking cold backups of my database which is in noarchive mode on a daily basis; now I am planning to change my backup strategy to decrease the downtime.

Tape backup but no Oracle backup Our server crashed and we do not have an Oracle backup, but we have a tape backup. The error we get is that the system.dbf is inconsistent with the control file.

Recover Oracle databases This book excerpt explains how to recover from the loss of a controlfile, redo log file or system-critical or nonsystem-critical datafile.

Recovering crashed database with corrupted undo tablespace I have a small Oracle 10g database. The database runs under archivelog mode. Recently my database crashed and it looks like the undo tablespace has been corrupted. How can I recover it?

Simulating restoration of tablespace using RMAN I want to simulate a restoration of a tablespace on a separate database. I do not have a separate instance nor do I have resources to make it available. Hence I plan to test the restoration of the tablespace on the RMAN database and after ensuring that the tablespace is restored, I will drop it. How do I go about it?
