Defining the Database Space Trigger
To define settings for the database trigger, first complete
the following fields and then click Finish, or
click Cancel to end the task. The trigger
determines when and how ADSM deals with space shortages in the
database.
DB Full Percentage
Enter the utilization percentage that specifies when ADSM
automatically allocates more space for your database.
- Specify an integer from 0 to 99.
- A value of zero (0) disables the space trigger.
- The default is 80.
DB Space Expansion Percentage
Enter the percentage by which ADSM expands the database.
- Specify an integer from 0 to 200.
- The database requires a minimum value of 4MB (5MB file
with processing space).
- Expansions are in units of 9MB.
- A value of zero (0) disables expansion.
- The default is 20.
DB Expansion Prefix
Enter the prefix that ADSM will use in creating files to
expand the database. The database expansion prefix is a valid
directory path meeting the following criteria:
- The maximum length is 250 characters for AIX, HP-UX, and
Sun Solaris; 200 characters for Windows NT. This is not
an option for for MVS or VM.
- The prefix name may include one or more directory
separator characters.
- ADSM does not check the prefix name for validity. If you
specify an incorrect prefix, automatic expansion can
fail.
DB Maximum Size (Megabytes)
Enter an integer that specifies the maximum size of the
database.
- Specify an integer from 5 to 999999999.
- Specifying a value of zero (0) or omitting this parameter
disables checking for maximum size.
- The default is 0.
