50 Chapter 4: Enabling and Using ColdFusion MX Features
2 Ensure that the application is compatible with ColdFusion MX for IBM WebSphere
Application Server. For a description of differences between this edition and ColdFusion MX,
see “Differences between ColdFusion MX and ColdFusion MX on WebSphere” on page 12.
3 Install ColdFusion MX for IBM WebSphere Application Server on a test server that has IBM
WebSphere Application Server installed.
4 Move the directory with the application under the cf_root directory on the test server.
5 Test the ColdFusion MX application on the test server. Using a source control system, make
any necessary changes to the application. Ensure that you test all application features under
load, not just with a few users.
Tip: A number of testing applications are available for download from the web. For more
information, see the Support section of the Macromedia website (http://www.macromedia.com/
support).
6 If you encounter problems that do not seem to be related to the code, ensure that you are using
comparable Administrator settings. For example, Java Virtual Machine (JVM) settings are
handled by your application server, not ColdFusion MX. For more information, see
“Differences in the ColdFusion MX Administrator” on page 14.
Using RDS
If you use Macromedia Dreamweaver MX or HomeSite+ to develop your applications, Remote
Development Services (RDS) lets you access a remote ColdFusion MX server using HTTP. Using
RDS, IDE users can securely access remote files and data sources, build SQL queries from these
data sources, and debug CFML code. However, to maximize security, do not install RDS on
production servers.
Note: ColdFusion MX does not support using RDS if you install multiple instances of ColdFusion MX
on a single web server.
About RDS configuration
In ColdFusion MX for IBM WebSphere Application Server, RDS support typically requires two
web modules:
• The ColdFusion MX web module
• The RDS redirector web module, also called the RDS application.
The ColdFusion MX web module handles RDS requests in addition to all requests for
ColdFusion pages.
If the ColdFusion MX context root is anything other than /, the redirector web module redirects
RDS requests (which always go to the /CFIDE context root) to the ColdFusion MX module. The
RDS redirector web module must have the context root /CFIDE and is normally installed in the
same directory as cf_root.
Note: If you install ColdFusion MX at the / context root, you do not need the RDS redirector web
module.
The instructions in the installation chapters describe how to install and disable RDS support.
This section describes how to reconfigure RDS support if you change the ColdFusion MX
application context root.
