Charting Settings page The ColdFusion charting and graphing engine lets you produce highly customizable business graphics, in a variety of formats, using the cfchart tag. You use the Charting page in the Administrator to control characteristics of the engine. The following table describes the caching and thread settings for the ColdFusion charting and graphing engine: Setting Cache Type Maximum number of images in cache Max number of charting threads Disk cache location Description Set the cache type. Charts can be cached either in memory or to disk. In memory caching is faster, but more memory intensive. Specify the maximum number of charts to store in the cache. After the cache is full, if you generate a new chart, ColdFusion discards the oldest chart in the cache. Specify the maximum number of chart requests that can be processed concurrently. The minimum number is 1 and the maximum is 5. Higher numbers are more memory intensive. When caching to disk, specify the directory in which to store the generated charts. Java and JVM Settings page The Java and JVM Settings page lets you specify the following settings, which enable ColdFusion MX to work with Java: Setting Java Virtual Machine Path Initial Memory Size Maximum Memory Size Class Path JVM Arguments Description The absolute file path to the location of the Java virtual machine (JVM): jvm.dll in Windows or jvm.so in Solaris, Linux, and HP-UX. The JVM initial heap size. Default is 8196 MB. The JVM maximum heap size. Default is 512 MB. The file path(s) to the directories that contain the Java classes used by ColdFusion MX. Use a comma-delimited list for multiple entries; for example, c:\foo,d:bar The arguments to the JVM. Use a space to separate multiple entries; for example, -Xint -Xincgc Before ColdFusion saves your changes, it saves a copy of the current jvm.config file as jvm.bak. If you r changes prevent ColdFusion from restarting, use jvm.bak to restore your system. For more information, see the online Help. Server Settings section 15
