Chapter 4: Administering Server Pools
46 FlashCONNECT Administrator’s Guide
FlashCONNECT enabled Web server should use. In the following examples, Apps
represents an item in the w3Apps file.
Using the information in the Web Server 1 row in the table above:
• to specify Web Server 1 for the Accounting server pool to Database Server 1 or
2, use the URL:
http://WebServer1/cgi-bin/fcisapi.dll?w3exec=Apps &w3ServerPool=Accounting
• to specify Web Server 1 for the Payroll server pool to Database Server 2, use the
URL:
http://WebServer1/cgi-bin/fcisapi.dll?w3exec=Apps &w3ServerPool=Payroll
Using the information in the Web Server 2 row in the table above:
• to specify Web Server 2 for the Accounting server pool to Database Server 2, use
the URL:
http://WebServer2/cgi-bin/fcisapi.dll?w3exec=Apps &w3ServerPool=Accounting
• to specify Web Server 2 for the Payroll server pool to Database Server 2 or 3, use
the URL:
http://WebServer2/cgi-bin/fcisapi.dll?w3exec=Apps &w3ServerPool=Payroll
Automatic Load Balancing
When providing the same service on multiple database servers, the load can be
automatically balanced between systems using server pools and w3Monitor. This is
possible because:
• connections from multiple database servers can be assigned to the same server
pool on one or more Web servers.
• FCService uses server pool entries to any database server supporting that server
pool.
• w3Monitor creates and destroys connections as needed.
See w3Monitor Application
in the FlashCONNECT Programmer’s Guide for additional
information.
To implement automatic load balancing:
1. Specify the relationship (which system should process a request and which
server pool to use in processing that request). See Specifying the Relationship
.
