• Normal. The normal store request is placed in the queue for
processing along with all other resource requests.
•Emergency.
The
fspolicy command maintains an internal store and
truncate candidate list of files. When the command is invoked,
those candidates meeting the criteria for storage or truncation
are processed. This candidate list can be overridden with the -w
option that scans the entire file system looking for potential
store and truncation candidates that meet the defined DataClass
group mintime requirements. Although this process is database
intensive, it should be performed on a regular basis as well as
any time an interrupt occurs.
This option should be run during times of minimal FileServ
software activity or executed through
cron.
Running as a cron
Event
To invoke fspolicy on a periodic basis, use the UNIX cron
utility.
The
cron utility is a permanent process that is started by
/etc/rc.local. This utility consults the files in the
$FS_HOME/.crontab directory to determine which tasks to
perform and at what time.
Note
To run fspolicy to store a very large number of files, (a
million or more) make sure you have sufficient memory.
The required memory should equal the maximum number
of files to store times 425.
Note
For more information on crontab, refer to the man pages.
