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:

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.

Setting Description

Cache Type Set the cache type. Charts can be cached either in memory or to

disk. In memory caching is faster, but more memory intensive.

Maximum number of

images in cache

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.

Max number of

charting threads

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.

Disk cache location When caching to disk, specify the directory in which to store the

generated charts.

Setting Description

Java Virtual Machine Path 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.

Initial Memory Size The JVM initial heap size. Default is 8196 MB.

Maximum Memory Size The JVM maximum heap size. Default is 512 MB.

Class Path 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

JVM Arguments The arguments to the JVM. Use a space to separate
