To administer Search caching, navigate to /atg/search/routing/CacheService in the Component Browser of the Dynamo Admin UI. The Cache Statistics section provides information on current cache configuration and effectiveness.
Note that the Avg Get Time value can look large due to the low resolution of the timer for this value; this is not a cause for concern in itself, but if the value increases sharply, it may represent a problem with your configuration. For example, a value of 0.8 seconds could be considered normal, but 8 seconds indicates a problem.
The page also provides access to the following actions:
Clear Statistics - Resets to zero the statistics that appear in the
CacheServicecharts (see below).Disable/Enable - Turns the caching service off or on.
Flush to Disk - Saves the portion of the cache currently in memory to disk.
Clear Cache - Deletes all cached information.
The page includes charts that show how caching affects your site, and which include the following information:
Hit Rates - The percentage of queries that have been satisfied by cached data. A high hit rate means that caching is working well.
Maintenance Time - The percentage of time the cache spent purging itself vs. serving requests. A large maintenance time indicates that your cache is not optimally configured.
Requests/Hits per Second - The number of search requests, the number of those requests that were served by cached data, and the number of items evicted from the cache.
Note: If you are using the QueryConsole sample application to test caching behavior, its Cache Responses setting is false by default; change this value before testing.
