Pre-restore checklist

To prepare for a restore:

• Determine if you need to restore. If one or more of these problems is true, you perform a restore to fix the problem:
  • Has data been lost or corrupted?
  • Does a committed transaction error need to be undone?
  • Is the database server down or has a disk failed?
  • Is a storage space or chunk down or inconsistent?
• Diagnose the problem by using database server monitoring tools.
• If the root dbspace or the dbspaces that contain the physical log and logical-log files need to be restored, you must perform a cold restore. The database server must be offline during a cold restore. Ask your client users to log off the system.
• Contact the appropriate vendor to resolve the following types of problems before doing a restore:
  • The storage manager
  • The XBSA connection
  • The operating system
  • The storage media
