24 Chapter 2 Basic ColdFusion MX Administration

Scheduled Tasks page

You use the Scheduled Tasks page to schedule the execution of local and remote web

pages and to generate static HTML pages. The scheduling facility is useful for

applications that do not require user interactions or customized output. ColdFusion

developers use this facility to schedule daily sales reports, corporate directories, statistical

reports, and so on.

Information that is read more often than written is a good candidate for scheduled tasks.

Instead of executing a query to a database every time the page is requested, ColdFusion

MX renders the static page with information generated by the scheduled event. Response

time is faster because no database transaction takes place.

You can run scheduled tasks once; on a specified date; or at a specified time, daily, weekly,

or monthly. You can run a scheduled task daily, at a specified interval, or between

specified dates.

The Schedule Task page lets you create, edit, and delete scheduled tasks. For more

information, see the online Help.

System Probes page

System probes help you evaluate the status of your ColdFusion applications. Like

scheduled tasks, they access a URL at a specified interval, but they can also check for the

presence or absence of a string in the URL. If the URL contents are unexpected, or if an

error occurred while accessing the URL, the probe can send an e-mail alert to the address

specified in the System Probes page. The probe can also execute a script to perform a

recovery action, such as restarting the server. All probe actions are logged in logs/

probes.log. The System Probes page also displays the status of each probe.

You use the buttons in the Actions column in the System Probes table to perform the

following actions:

Because probes run as scheduled ColdFusion tasks, they will not run if the ColdFusion

MX server on which they are hosted crashes, or if the host web server crashes or otherwise

does not respond.

Code Compatibility Analyzer page

The Code Compatibility Analyzer evaluates your ColdFusion pages for potential

incompatibilities between ColdFusion MX and ColdFusion Server 5. For more

information, see Migrating ColdFusion 5 Applications.
