With the "java" command there are several options you can use to up the memory allocation. Check the Java tool doc documentation for details.


-Xmsn Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB. Examples:
-Xms6291456
-Xms6144k
-Xms6m

-Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:
-Xmx83886080
-Xmx81920k
-Xmx80m

-Xssn Set thread stack size.


If you google on java "-xmsn" "-xmxn" "-xssn" you'll get lots of good information

Doody calls. I would really rather that it didn't. Comfort me wise and sterile tiny ad:
