E-6 SunLink SNA 9.1 PU2.1 Server Configuration Guide—August 1997
E
Note – If you are configuring printer connections and TN3270 connections
from the same desktop, you cannot use the geographical load balancing
keyword. This is because the incoming IP address used for looking up the user
record is the same for both. In this case, either use normal load balancing or
use RFC1646/RFC1647 standards for associated printers.
E.3.2 Geographical Load Balancing Example
The procedure described in this section assumes that site 1 located in Los
Angeles and site 2 is located in New York.
POOL-1
is a pool of LUs located at
site 1.
POOL-2
is a pool of LUs located at site 2.
The default geographical load balancing keyword
glb
is used so that all clients
can connect to a resource using the same name. At least one secondary DNS
has been implemented in each location and each desktop has been configured
to point to the secondary DNS.
All TN3270E client connections use the following connection parameters:
•
Hostname:
glb.sna.sun.com
•
Connection Resource: Not required
Each site has a user record associated with it. The user records for site 1 and
site 2 specify the following:
Note – Instead of specifying the Client Address Type as IP ADDRESS, you can
specify the Client Address Type as IP HOSTNAME. In this case, you specify
the IP Hostname parameter instead of the IP Address and Mask parameters.
