The memory management subsystem assesses the memory needs of all server
and NLM processes and determines where the freed memory should be used.
The Java Virtual Machine and any modules that are loaded into protected
address spaces use virtual memory. Both the modules and the data they access
are subject to being swapped to disk.
When data is moved from memory to disk, it is stored in a swap file. You can
create one swap file for each NetWare volume. A swap file is created for
volume SYS: by default.
To create a swap file, delete a swap file, change swap file parameters, or view
information about the swap file, you can use NetWare Remote Manager,
MONITOR, or the SWAP command at the System Console prompt. See
“Using Virtual Memory” on page 26.
Swapping the data between memory and disk requires additional system
resources, but it increases the memory available for use. The availability of the
additional memory can improve overall server performance.
