Question : Permanent Heap used by Weblogic 8.1 with JRockit 1.4

Is there a place in the startup script for weblogic to specify the permanent heap for the application to use? I know there's the Xms - Xmx but I am not sure where do you define the permanent heap that the application will use while it is running in the application server. Perhaps I need a little edeucation here, but I was told that you can specify the Mn-Mx heap that the instance will use and also specify from the Xmn-Xmx how much to dedicate to the application to run in. Is this true if so where can I find information on this ?

Answer : Permanent Heap used by Weblogic 8.1 with JRockit 1.4

Hi,

Sample Start-up Command
A sample start-up command, with some tuning options specified, might look like this:

java -verbose:memory -Xgc:gencopy -Xmx:256m -Xms:64m -Xns:24m myClass
In this example, the following options are set:

-verbose:memory—Displays verbose output about memory usage.
-Xgc:gencopy—A generational copy garbage collector will be used.
-Xmx:256m—The maximum heap size is set to 256 megabytes.
-Xms:64m—The initial heap size is set to 64 megabytes.
-Xns:24m-—The nursery size is set to 24 megabytes.
