7.5 Set the RAM disk Protection Parameters
You should verify that the RAM disk protection parameters are appropriate for your application.
The RAM disk protection feature prevents the disk from running out of room, which could result in
the loss of data. Monitoring of available space on the disk by the ASG Guard/ASG Guard Plus is
done continuously. You can configure the ASG Guard/ASG Guard Plus to delete files
automatically after a specified number of days or when the amount of data on the RAM disk
reaches a preset critical level.
Files are not deleted automatically. If you do not specify a critical percentage and the directories
from which files are to be deleted, you will have to monitor the disk and delete files when
necessary. The ASG Guard/ASG Guard Plus has default values, which may or may not fit your
application. Failure to raise the free space above the critical level causes a ".DISKCRIT" event to
be generated. The event .DISKCRIT can be included in your Action Table along with the
specified action to be taken.
The RAM disk protection parameters can be viewed by using the DDP (Display Disk Parameters)
command or modified by using the SDP (Set Disk Parameters) command.
