Adding a second control file

I have a database with a single control file running. Is there any way to add a second contol file, or what is the best way to backup the existing control file?

There is an easy way to add more than one control file. And it's a good idea to do so. Just follow these simple steps.

  1. Shut down the database with NORMAL or IMMEDIATE options.
  2. Copy the single control file to its new location. Rename it if you want or need to.
  3. Modify your INIT.ORA paramter file. Change the CONTROL_FILES parameter to point to both control files.
  4. Startup the database.
It's as simple as that. I usually have three control files for each database.
