Protecting Your Data : Recovering a Database : Recovering from a full disk : After-image area disk
After-image area disk
If a variable-length after-image extent fills a disk, the database engine automatically switches to the next AI extent if that extent is empty. If the extent is not empty, the database shuts down unless the After-image Stall (-aistall) startup parameter was specified.
To restart a database after a full AI extent causes a shutdown:
1. Back up the least recently used full after-image extent. Use the RFUTIL AIMAGE EXTENT FULL utility to find out which extent this is.
2. Use the RFUTIL AIMAGE EXTENT EMPTY utility to mark the extent as available for reuse.
3. Restart the database.
