roll area (BC-CST-MM)

Memory Management (BC-CST-MM)

Memory area of a fixed (configurable) size that belongs to a work process.

The roll area is located in the heap of the virtual address area of the work process. When the context of the work process is changed, the data is copied from the roll area to a common resource, the roll file. A roll buffer, which is part of shared memory, is located between the two to prevent frequent copying.
