2. Assign the connection (to any database server which supports that server pool).

.
3. Set up w3Monitor on each database server to maintain a minimum of one or
more free connections to the Web server.
How it Works:
For example, there are two database servers (A and B) supporting one Web server.
Two connections to the default server pool are made from each database server to
the Web server (Table 2). w3Monitor is set up on each database server to maintain a
minimum of one free connection to the Web server.
Table 1: Two database Servers Support One Web Server
The first two user requests are assigned to connections 1 and 2, both to Database A.
At this time, the w3Monitor running on Database A automatically adds one more
connection (number 5), as reflected in Table 3.
Table 2: w3Monitor Automatically Adds a Connection
The third and fourth user requests are assigned to connections 3 and 4, both to
Database B. At this time, the w3Monitor running on Database B automatically adds
one more connection (number 6) as shown in Table 4.
