The maximum number of disk writes per request (shown by the DKWR statistic)

At certain points during loop processing of a request, the elapsed number of disk writes for the request is compared to the value of MDKWR. If the elapsed number is greater, you are informed that the request is long. The user can either continue or cancel the request.

In batch jobs, in application subsystems, or if the value of the PROMPT parameter includes the X'10' option, this interaction with you does not happen and the request is canceled.

The maximum MDKWR value is X'FFFFFFFE' (4,294,967,294). If MDKWR is set to -1, there is no limit on DKWR.
