The time period in minutes between Data Set Services checks for abandoned buffers, open files, or inactive application servers.
Due to unforeseen environmental errors, transactions may abnormally terminate while holding open files and other I/O resources.
These scans locate idle resources and return them to an available status and ensure that no file is held idle for more than
two consecutive scan intervals. Specify the number of minutes as an integer value between 5 and 120. The default for MFA is
30 minutes, most application servers 5 minutes, and TSO 20 minutes.
