In an average size cluster, 50 nodes, a RM should not need more than 4GB. In a large cluster,hundred or more NM's, you need to increase that. For a NM you can normally leave that at 1GB on small nodes or 2-4GB on large nodes. The number of containers you can run on a node ...
If you want to increase your heap space, you can use java -Xms<initial heap size> -Xmx<maximum heap size> on the command line.Profiling your application to find out why your heap size is being eaten.AV program may reserving a small block of memory in every address space, thereby ...
Then, the minimum memory size will be half of the maximum memory size(250m). It is 125m. You can also increase the maximum memory size but you should keep in mind that heap memory size is a portion of the total memory in...
If you install the Sun Message Library for HL7, we recommend that you increase the NetBeans IDE heap memory size. If the heap size is not sufficient it could result in out of memory exceptions from the built-in parser. Use thenetbeans.conffile to set the heap size for the JVM on whic...
