Symptoms

Coherence*Web has a set of Context parameters that can used to control its configuration. These can either be set in a web application's web.xml file, or can (in theory), be set as system properties.

In this problem the issue is that two of the parameters relating to the overflow attributes that used in the split session model (the default), are not set by their appropriate system properties:

• OverflowCacheName
• OverflowThreshold

For example, if you were to set the system properties for those attributes to the following values:

When you use a tool like jconsole to examine the Coherence*Web HttpSessionManager MBean, you'd see that neither the overflow threshold or overflow cache name is using the new values, as shown in this image:



While the SessionCacheName is correct, the OverflowCacheName and OverflowThreshold are still set to their default values.
