ColdFusion UDF's (User Defined Functions) can be passed to other functions as if they were variables. To pass a UDF to a UDF just refer to it by name (without the parenthesis). This allows you to create functions with callback functions (similar to C's pointers to functions). (Applies to:...
By default, Custom Tags have no visibility into the caller space. This means that User Defined Functions (UDF's) in your code cannot be invoked from within Custom Tags in your page. The solution? If the UDF's are in a separate file use to include them right into the Custom Tag. If they are in the...
The ColdFusion Administrator Throughput Report (under Tools, Server Reports) lets you monitor overall system performance giving you a snapshot of server activity and throughput including data in and out per second, average CPU and memory usage, and more. (Applies to: ColdFusion 5 or later)
The ColdFusion Administrator Timeout Requests Report (under Tools, Server Reports) lets you monitor the number of requests that have timed out (took to long to process). This information is useful in monitoring changes in system performance and load. (Applies to: ColdFusion 5 or later)
The ColdFusion Administrator Requests in Progress Report (under Tools, Server Reports) lets you monitor the number of requests that are being processed (not queued) at any time. This information is useful in monitoring changes in system load. (Applies to: ColdFusion 5 or later)
The ColdFusion Administrator Queued Requests Report (under Tools, Server Reports) lets you monitor the number of requests that are queued (waiting to be processed by ColdFusion) as well as the maximum queue size. This information is useful in determining overall system performance, as well as to...
The ColdFusion Administrator Cache Pops Report (under Tools, Server Reports) lets you view how effectively the ColdFusion cache is being used by monitoring how many files how to be ejected from it. This information is useful in determining when to increase the template cache size. (Applies to:...
The ColdFusion Administrator Database Operations Report (under Tools, Server Reports) lets you view database response times and the greatest number of databases requests processed at any given time. This information is useful in troubleshooting database settings and driver related issues. (Applies...
The ColdFusion Administrator Requests Report (under Tools, Server Reports) lets you view averages of request details, as well as CPU and memory usage for the current day or any specified date range. This information is useful in troubleshooting resource and response time problems. (Applies to:...
ColdFusion 4.x introduced clustering and integration with hardware based load-balancing (via Cisco hardware). ColdFusion 5 greatly simplifies this integration by eliminating the need for software based clusters. Instead, integration with load-balancing hardware can be configured simply by...
