A system PAGE dataset stores 4Kbyte blocks ('pages') of idle virtual memory when virtual memory allocation exceeds the real memory on the machine. The PAGE dsets are defined as special VSAM files and assigned to the system for use.

Application programs don't usually need to be concerned about the paging process. The program runs within the REGION size set by the system defaults or JCL and the system moves pages in and out of memory depending on workload. Excessive paging can slow the elapsed time of the program.

Does this answer your question?
