one, this script will not damage, or even write to the existing WindU registry. The script will also preserve your
start script and your odbc.ini files so they can be upgraded.
Once the script has completed, you are free to do a package remove of the existing ColdFusion installation.
During the installation, ColdFusion 4.5.1 will access the migrated registry and complete the initialization process
so it can be used. It will also restore the saved start script and odbc.ini file, making the necessary changes to
them so they are version 4.5.1 compliant.
All intermediate files are saved into a directory called migration, in the ColdFusion installation directory for
reference.
Redirecting processing to a Custom Error Page for specific errors
In certain cases, when the communication between the stub (residing in the webserver process space), and the
ColdFusion Application Server is disrupted or broken, the following error page is rendered:
"Server busy or unable to fulfill request. The server is unable to
fulfill your request due to extremely high traffic or an unexpected
internal error. Please attempt your request again (if you are repeatedly
unsuccessful you should notify the site administrator)."
In ColdFusion Server 4.5, processing can be redirected to a user-specified location when this error condition
occurs in the stub program. Please edit the
cfremote.ini
file located in your <ColdFusion Installation Directory>,
and add a key/value pair specifying the error condition and the redirection location. In this release only the
ERROR_PIPE key is supported.
The following is an example where the error processing is redirected to
nopipe.htm
ERROR_PIPE = "http://127.0.0.1/ErrorPages/nopipe.htm"
NOTE: ColdFusion Administrator cannot be used to specify these settings. Furthermore every attempt should be
made not to change the other settings in this file. Please see Advanced ColdFusion documentation for details
about the use of the other settings in this file.
Load Balancing and Failover with ClusterCATS
ClusterCATS consists of two components, the ClusterCATS Server and the ClusterCATS Explorer. ClusterCATS
Server provides failover support, load balancing, and other features to help you guarantee the availability of your
ColdFusion applications.
For more information about configuring Web server clusters, refer to Administering ColdFusion Server.

When creating a cluster using ClusterCats for ColdFusion, enter the license key "GoColdFusion"
l
ClusterCATS is now integrated into the ColdFusion Server Linux installation.
l
Windows 2000 systems must be configured to use ClusterCATS dynamic IP addresses for Failover (High
Availability installation option) to function properly. Static addresses are currently not supported on
Windows 2000 systems.
