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.
