Recovery Operations for a Nearly Full Database File
Recovery Operations for a Nearly Full Database File
When a database file is 90 percent full or more, you can modify the file extents
dynamically with FUP or perform other procedures according to your system policies.
To allocate additional extents to the file MEMOS:
> FUP
- ALTER MEMOS, MAXEXTENTS 20
- INFO MEMOS, DETAIL
A report such as this one is sent to your home terminal:
This report shows that the maximum extents allocated to this file have been increased
to 20 and that the file MEMOS is now only 78.5% full.

Note. Allocating additional extents to any file causes that file to take up more disk space.
Before you change the maximum allowable extents for any file, as shown in the next example,
check your local procedures to determine whether this is the appropriate action for you to take.
