A Memory Monitor can track the activity of three types of memory space:
You can see this swapping of segment use in a Memory Monitor display. For example, look at the graphic above. Once you click on Start, the graph displays an ascending line, showing that the system is allocating new space. When the segment being used becomes full, the system conducts a scavenge. At this point, the graph displays a descending line. When the system allocates new space for the other memory segment, the line ascends again.
To examine memory allocation for a single segment, select Memory Segment from the Monitor menu; then select an old or new segment from the displayed list of segments that you can examine.
To examine memory allocation for old space, select Old Space from the Monitor menu.
To examine memory allocation for fixed space, select Memory Segment from the Monitor menu; then select a fixed segment from the displayed list of segments that you can examine.
