To do this, follow these steps: Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list. With generational heap, the heap has a special area called ‘nursery’ or ‘new generation’ that is used for short lived objects. HeapCreate: Creates a heap object. Original KB number: 947246. As mentioned earlier GC is responsible for scanning the heap and clearing unused objects so that the memory can be reclaimed. In some cases, the CPU utilization of the Server can go up significantly as well. 3. What this means is, after certain period, the heap will be filled with objects are being used by the application and GC will NOT be able to reclaim those. But, each time I read a record, it occupies the memory and after a certain limit the plug in stops working, because of out of memory. Only JVM can decide when to run GC. HeapCompact: Coalesces adjacent free blocks of memory on a heap. Use JDK tools such as jconsole,visualvm and jstat.
