Roll and Paging Buffers, Extended Memory

Definition

The roll and paging buffers are the preferred working area of the roll and paging areas for an instance (application server). The remaining area is located on disk as roll and paging files. The user context is stored in the extended memory and the roll area (when the job is "rolled out" of a work process). The paging area stores special data for the ABAP processor, while the extended memory stores a large portion of the internal tables of a program.

You set the roll and paging buffers, as well as the extended memory using the parameters in the instance profile.
