Those resources are "in addition" to those used by the Job Entry Subsystems themselves. They protect the same thing, basically, but have different scope and granularity. MainView's resources are more "general" in some sense and are intended to control access to SPOOL data sets to a degree that is likely to be sufficient for the majority of our customers who do not use any of the resources in CLASS JESSPOOL. For those that do use JESSPOOL, it may still be useful to use the MainView resources you identified in your question (for example, it could serve to somewhat limit access so that there are fewer violations for the JESSPOOL resources, which are sometimes difficult to manage at many sites because of complex or obscure naming conventions).
There is no way to bypass the resource access authorizations made for JESSPOOL. They are done by JES (et al.).
