Defining the Recovery Log Space Trigger
To define settings for the recovery log space 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
recovery log.
Log Full Percentage
Enter the utilization percentage value that specifies when
ADSM automatically allocates more space for the recovery log.
- Specify an integer from 0 to 99.
- A value of zero (0) disables the space trigger.
- The default is 80.
Log Space Expansion Percentage
Enter the percentage by which ADSM expands the recovery log.
The default is 20.
- Specify an integer from 0 to 200.
- The Recovery Log requires a minimum value of 8MB (9MB
file with processing space).
- Expansions are in units of 9MB.
- A value of zero (0) disables expansion.
- The default is 20.
Log Expansion Prefix
Enter the prefix that ADSM will use in creating files to
expand the recovery log. The log 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 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.
Log Maximum Size (Megabytes)
Enter an integer that specifies the maximum size of the
recovery log.
- Specify an integer from 5 to 5000.
- The default is 0.
