| IDWR
has begun implementing ArcIMS for both internal and external
applications. ArcIMS 3.0 has proven to be a useful tool, and
an easy one with which to create applications. Configuring
the software has been considerably more difficult.
The simplest implementation
is to put all ArcIMS components on one server. However, IDWR
uses the State of Idaho web server, which is outside the
state firewall. That requires our ArcIMS implementation to
use two servers.
The two-server configuration
worked until applications were written that required large
amounts of data. IDWR has approximately 50 GB of vector and
image data that are accessed by various ArcIMS applications.
We modified our ArcIMS configuration to include a third
server to assure efficient data-access and good ArcIMS
performance. This 3-server
configuration is described in a pdf-format document. |
