Using SWAP
 If a swap file is being used when it is deleted, then the swapped data is
moved to another swap file. If there is no other swap file, an error
message is displayed and the file is not deleted.
 You can create one swap file per volume. The swap file for the Sys
volume is created by default; you can delete it if necessary.
 Data moved to disk by virtual memory will be stored in any available
swap file; it does not matter which volume the swap file is on. Generally,
you will place swap files on the fastest volume or the one with the most
available space.
 You can add a swap file to a volume by executing the SWAP ADD
command, even if the volume is not mounted. Once you’ve added the
swap file, the file will be created when you mount the volume.
 When you dismount a volume, the swap file is deleted. To keep a swap
file on that volume, you must create the swap file again. The exception is
the SYS: volume swap file, which is created by default. For convenience,
DEL vol_name Delete a swap file from the designated volume.
If you are using protected address spaces, the
Novell
®
JVM for NetWare
®
product, or any
other application that uses virtual memory, be
sure to keep at least one swap file.
By default a swap file is created on the Sys
volume whenever you start the server. If you do
not want a swap file on Sys, place the SWAP
DEL command in the startup.ncf file before the
command to mount volumes.
PARAMETER = vol_name
parameter = value

the designated volume.
You can specify the following parameters:
MIN=, MAX=, and MIN FREE=.
These parameters specify minimum and
maximum size of the swap file and the
minimum free space that must be left on the
volume. Values are in millions of bytes.
