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.
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.
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:
$DATA.DATA1.MEMOS
ENSCRIBE
TYPE U
CODE 101
EXT ( 2 PAGES, 2 PAGES )
ODDUNSTR
MAXEXTENTS 20
BUFFERSIZE 4096
OWNER 8,255
SECURITY (RWEP): NUNU
DATA MODIF:
CREATION DATE:
LAST OPEN:
EOF 567022 (78.5% USED)
FILE LABEL: 649 (22.8% USED)
EXTENTS ALLOCATED: 10
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.
