Windows

■

If you plan on running more than two separate instances of Sun Java System Web Server on

your system, an additional 16 MB RAM for each server instance.

Paging space at least as large as the amount of RAM on your system (twice the amount of

RAM is recommended).

■

If you intend to use hostnames during the Sun Java System Web Server installation, DNS

You have two port numbers - one for the Administration Server and the other for the rst

Sun Java System Web Server server instance. For information on choosing port numbers for

your server, see

“Choosing Unique Port Numbers” on page 21.
