The Palace preferences file 

NOFORK  TRUE | FALSE

If 

NOFORK 

is

 TRUE,

 the server process is prevented from forking into the background. 

This option is provided for advanced UNIX users and administrators only. The default 

value is 

TRUE

.

FRONTEND "portNumber" "address"

These values provide your Palace with a port and host address for its frontend  the 

address made known to users. The default value is:

"9998" "0.0.0.0"

Note that this value consists of two strings. The value 

0.0.0.0 

is the address 

associated with the primary interface (that is, the default IP address of the machine 

you are using).

You must specify at least one frontend. You can run a maximum of 10 primary 

frontends off a single hub. Individual frontends can reside on different computers as 

long as they are the same byte order as the hub. These strings must be in double 

quotes. See 

PORT, BINDADDRESS

.

PROPCACHESIZE 

numberOfProps

This feature keeps a configurable number of props in memory at the frontend. This 

reduces the amount of processing that needs to occur at the hub, and generally results 

in better server performance. The default is 10. Increasing this number will result in 

higher memory consumption by each frontend process. This should be done with 

caution on computers with limited memory, because allocating a large prop cache will 

result in swapping, which may result in degradation of performance.

NOTE   

Busy servers will use a lot of RAM if you increase this value. Setting this value 

to more than 30 is generally not recommended.

USERLIMIT 

number

This keyword lets you manually set the number of users that can connect to your 

server. You can set this limit to a lower number than that specified by your registration 

code.

The Palace preferences file

The keywords in your Palace preferences file (

pserver.prefs)

determine the 

preferences for your Palace. You set these keywords with the indicated Palace 

commands; generally, you do not need to edit the file directly. If you do, be sure not to 

edit the file while the server is running.
