DASDMON is run as a background job that monitors system DASD, and temporary storage used by active jobs on the system. It automatically holds any job that uses over the set level of temporary storage. Warnings are given if
The overall DASD % rises above a set level (separate to the standard 90% warning that OS/400 sends)
The percentage rise over the user defined check period exceeds your chosen value.
Usage: STRDASDMON (F4) to submit it and ENDDASDMON to terminate the background job.
