Administrator's Reference
Use this command to update settings that determine when and how TSM
resolves space shortages in the database or recovery log.
This command does not create new volumes. It does extend the
database and recovery log space if available. If it is not available
TSM displays a message indicating the amount of new space needed. You
can then use these values to allocate the needed space.
See the DEFINE SPACETRIGGER command for more information.
Privilege Class
To issue this command, you must have system privilege or unrestricted
storage privilege.

Parameters
- DB
- Specifies a database space trigger.
- LOG
- Specifies a recovery log space trigger.
- Fullpct
- Specifies a space utilization percentage of the database or recovery
log. When this value is reached, TSM tries to allocate more
space. This parameter is optional. You can specify an integer
value from 0 to 99. The default is 80. A value of zero (0)
disables the space trigger.
- SPACEexpansion
- Specifies, as a percentage of the current size, the amount by which the
database or recovery log can be increased. This parameter is
optional. Specify a value from 0 to 200. The default is
20. The database must be at least 4MB (5MB file with processing
space); the recovery log must be at least 8MB (9MB file with processing
space). New database or recovery log volumes must be multiples of 5MB
or 9MB respectively. A value of zero (0) disables expansion.
- EXPansionprefix
- Specifies the prefix that TSM uses to create new database or recovery log
files. The prefix name may include one or more directory separator
characters, for example,/sr/llp/adsmserv/bin/. You can
specify up to 250 characters. If you specify an invalid prefix,
automatic expansion can fail.
- MAXimumsize
- Specifies the maximum size, in megabytes, of the database or the recovery
log. This parameter is optional. When this size is reached,
expansion stops, and TSM issues a message. You can specify a value from
9 to 5000 (5GB) for the recovery log, or from 4 to is 9999999MB for the
database. A value of zero (0) or omitting this parameter disables
checking for maximum size.
Examples
Task 1
Update the setting of the database expansion to 50 percent.
- Command:
- update spacetrigger db spaceexpansion=50
Task 2
Disable automatic expansion of the recovery log.
- Command:
-
update spacetrigger log spaceexpansion=0
