Initiating MVScope sampling of a job
- Display the JUDEV view.
- Submit this job.(In your example, as shown in the following figure, the job is named BMVTAT4.) This action will allocate two temporary data sets, get 16 MB of virtual storage, and go into a continuous loop that references the storage and performs I/O to the data sets.
When the JUDEV view shows this job using the device where you directed it to allocate the //DD1 and //DD2 data sets, type M next to that row to initiate monitoring, as shown in the following figure:
