Intel AS/400 RISC Server, 170 Servers Button Operation, Cache Management Record Definition Loader

Button	Operation
Reset Counters	Resets the cache hit and miss counters back to 0.
Set Limit	Temporarily sets the cache limit to a new value.
	Setting the value lower than the current value will
	cause the cache to be cleared as well.
Refresh	Refresh the display of cache elements.
Clear Cache	Drop all the cached definitions.
Save List	Save a list of all the cached record data definitions.
	This list is saved in the RecordJSPs directory of the
	Webfaced application. The actual record definitions
	are not saved, just the list of what record definitions
	are cached. Once the cache is optimally tuned, this list
	can be used to preload the Record Definition cache.

Cache Management - Record Definition Loader

As a companion to the Cache Content Viewer tool, there is also a Record Definition Cache Loader tool, which is also referred to as the Bean Loader. This servlet can be used to pre-load the cache to aid in the determination of the optimal cache size, and then finally, to pre-load the cache for production use. To enable this servlet add the following two xml segments in the web.xml file.

<servlet> <servlet-name>BeanLoader</servlet-name> <display-name>BeanLoader</display-name>

<servlet-class>com.ibm.etools.iseries.webfacing.diags.BeanLoader</servlet-class> </servlet>

<servlet-mapping> <servlet-name>BeanLoader</servlet-name> <url-pattern>/BeanLoader</url-pattern> </servlet-mapping>

Invoking this servlet will present a Web page similar to the following.
