  2. Server Settings • Maximum # of Simultaneous Requests • Recommended 3 Per Processor • Timeout Requests after n seconds • Prevent unusually lengthy requests from using up server resources • Whitespace Management • Missing Template Handler • Site-wide Error Handler

  3. Caching • Maximum # of Cached Templates • Too low of number can slow down response time • Too high of number requires more memory • Experiment to find best setting for your server • Suggested to start with 1 page per MB of JVM size • Trusted Cache • ColdFusion will no not check for updated templates that are cached • Great performance enhancement for Production server that won't be updated

  4. Caching • Save Class Files • Recommended for Production Server • Cached web paths • Only for single-site web server installations • Cached Queries • Specify # of queries cached at once • Cached queries reside in memory • When limit is reached, oldest is removed • cachedwithin or cachedafter of <cfquery>

  5. Client Variables • Used for persistent data • Can be stored in 1 of 3 locations • Registry (Default storage) • Simple Implementation • Registry can become corrupt if it becomes too large • Cookies • Simple Implementation • Users can have cookies disabled • Datasource (Requires database) • Portable and not tied to host system • Complex Implementation

  6. Client Variables • Control Client Variable expiration • Default 90 days, Minimum 1 day • Disable Global Client Variable Updates • If checked, client vars HITCOUNT & LASTVISIT only update when Client vars set or modified • Client Variable expiration based on HITCOUNT and LASTVISIT • Alternate way to set Client Var Storage • <cfapplication name= "x" clientManagement= "yes" clientStorage= "dsn" or "registry" or "cookie">

  7. ColdFusion Mappings • Mappings allow you to point to files outside of webroot • Logical Path = Name of mapping • Directory Path = Absolute path to directory • Mappings can be used in <cfinclude> and <cfmodule> • Specify mapping with “/” • <cfinclude template=”/mymapping/file.cfm

  8. More Server Settings • Mail Server • Connect to default mail server, can also be set with <cfmail> • Server Port, Connection Timeout, Spool Interval • Mail logging settings • Charting Settings • Cache Type (memory or disk), Max # cached images, # of charting threads, disk cache location

  9. More Server Settings • Java and JVM settings • JVM Path = location of JVM.dll or JVM.so • Min and Max JVM Heap Size • Class Path and JVM Arguments • Archives and Deployment • Archive and deploy CF apps, configuration settings, dsn info and more • Settings Summary • Shows all CFMX configuration settings

  10. Data & Services • Data Sources • Setup & verify connections to Data Sources • Verity Collections • Manage collections for search interfaces • Verity K2 Server • For faster searching • Web Services • Registering a web service allows you to change web service URL without changing code

  11. Debugging Settings • Enable Debugging • For performance and security reasons it is recommended to only be used in development • Can be enabled in CFAdmin or in code • <cfsetting showdebugoutput=”yes” or “no”> • Custom Debug Output • Classic or Dockable format • Switch on or off specific debug content • Variables include Application,CGI,Client, Cookie,Form,Request,Server,Session,URL

  12. Debuggin IP Addresses • IP Address List • If 1 or more IP addresses are specified, debug is limited to those IP's only • No IP Addresses listed • If no IP address specified then debug is appended to all requests

  13. Logging and More • Manage CFMX Logging Options • Log Directory, Maximum Log File Size • Log slow pages taking longer than n seconds • Log Files • Useful to find bottlenecks • application.log, exceptions.log, scheduler.log, server.log, customtag.log, mail.log, etc. • Scheduled Tasks • Schedule execution of local and remote web pages

  14. Extensions • Java Applets • To use <cfapplet>, Applets must be registered • CFX Tags • Written C++ or Java, must be registered • Faster than custom tags since compiled • Custom Tags • Specify custom tag location besides default • CORBA Connectors • Must be registered, requires restart

  15. Security • CF Admin Password • RDS Password • Sandbox Security • A sandbox is a designated area of your site to which you apply security restrictions. • Control access to Data Sources, Tags, Functions, Files and Directories, IP Ports

  16. Resources • Macromedia CFMX Documentation • Configuring and Administering CFMX • http://www.macromedia.com/support/documentation/en/coldfusion/ • Live Docs • http://livedocs.macromedia.com/coldfusion/6.1/index.html
