Decrease Java heap dimension by lowering the values in the parameters MaxHeapFreeRatio (default value is 70%) and MinHeapFreeRatio (default worth is 40%) with the command-line choices -XX:MaxHeapFreeRatio and -XX:MinHeapFreeRatio. Reducing MaxHeapFreeRatio to as little as ten% and MinHeapFreeRatio to five% has correctly diminished the heap size with out a lot of performance regression; however, effects may well range greatly dependant upon your software.
Reduce the Java heap size by decreasing the values with the parameters MaxHeapFreeRatio (default worth is 70%) and MinHeapFreeRatio (default value is forty%) Using the helpful resources command-line alternatives -XX:MaxHeapFreeRatio and -XX:MinHeapFreeRatio. Decreasing MaxHeapFreeRatio to as low as ten% and MinHeapFreeRatio to five% has properly lessened the heap size with out an excessive amount of performance regression; nonetheless, results might vary greatly depending on your application.
Sets a personalized command or a series of semicolon-divided instructions to run when an irrecoverable error occurs. If your string incorporates spaces, then it have to be enclosed useful content in quotation marks.
