The short answer is no. There really isn't a reliable way in Java to accomplish this from within the java code. Therefore it will not be something that is internally supported in iBATIS. I would recommend you select a good profiling tool and do your best to surmise memory usage from it.

I was wondering if there was a way to determine the amount of memory being allocated by a iBatis cache. I read a thread called "Estimating amount of memory need for cache". However, the thread ended on 25 Jul 2005 with mention of an utility being developed. Was anything ever developed? Or is there a some other way to determine the size of a cache? I believe that the cache is storing query statements and the resulting objects in memory. Are the query statements the keys in a map with the values being object(s)? Also, how does the cache grow? Does it preallocate memory in the "map" based on the cache size or does it allocate just what is needed upon each object being added to the cache? Sorry for all the questions. Still fairly new to iBatis and trying to get a handle on these caching aspects. Thanks in advance for any help.
