CONFIGURING AND ADMINISTERING COLDFUSION 9
Using the ColdFusion Administrator
Last updated 2/21/2012
Request Tuning page
The Request Tuning page of the Administrator contains configuration options that you use to specify the number of
different types of requests and threads that ColdFusion can handle simultaneously.
Site-Wide Error Handler Specify a page to execute when ColdFusion encounters an error while processing a request. This
specification is relative to the web root. When you define a site-wide error handler or missing
template handler, ColdFusion does not log page-not-found errors and exceptions.
Note: If the user is running Internet Explorer with Show Friendly HTTP Error Messages enabled,
Internet Explorer only displays this page if it contains more than 512 bytes.
Maximum Size Of Post Data Limits the amount of data that can be posted to the server in a single request. ColdFusion rejects
single requests larger than the specified limit.
RequeSt Throttle Threshold Requests smaller than the specified limit are not queued or counted as part of the total memory.
Requests larger than the specified limit are counted as part of total memory and are queued if the
request throttle-memory size is exceeded.
Request Throttle Memory Limits total memory size for the throttle. If sufficient total memory is not available, ColdFusion
queues requests until enough memory is free.
Option Description
Maximum Number Of Simultaneous
Template Requests
The number of CFML page requests that can be processed concurrently. Use this setting to increase
overall system performance for heavy-load applications. Requests beyond the specified limit are
queued.
Maximum Number Of Simultaneous
Flash Remoting Requests
The number of Adobe Flash® Remoting requests that can be processed concurrently.
Maximum Number Of Simultaneous
Web Service Requests
The number of Web Service requests that can be processed concurrently.
Maximum Number Of Simultaneous
CFC Function Requests
The number of ColdFusion Component methods that can be processed concurrently through HTTP.
This does not affect starting CFC methods from CFML, only methods requested through an HTTP
request.
Maximum Number Of Simultaneous
Report Threads
The maximum number of ColdFusion reports that can be processed concurrently.
Maximum Number Of Threads
Available For CFTHREAD
CFTHREAD that runs concurrently. Threads that CFTHREAD creates in excess of the specified limit are
queued.
Timeout Requests Waiting In Queue
After n Seconds
If a request has waited in queue beyond the specified limit, time out the request. This value must be
at least as long as the Request Timeout setting (currently 60 seconds).
Request Queue Timeout Page Specify a relative path to an HTML page to send to clients when a template requests time out before
getting a chance to run. For example "/CFIDE/timeout.html.” This page cannot contain CFML. If a
page is not specified, clients receive a 500 Request Timeout error when their request does not get a
chance to run.
Maximum Number Of Running JRun
Threads
Maximum number of JRun handler threads that run concurrently. This option is used to set the
number of request threads that the underlying JRun J2EE application server runs at the same time.
This includes any non-ColdFusion requests such as JSP or HTML pages served through JRun.
Maximum Number Of Queued JRun
Threads
Maximum number of requests that JRun can accept at any one time. This is the number of requests
that the underlying JRun J2EE application server can accept at the same time.
