Arglist
The Arglist parameter in the server directive specifies JVM command-line
arguments. Example 3-1 shows a sample arglist for an NSJSP container class.
Java Runtime Arguments
You can add any of the following optional Java runtime arguments to the Java
Arglist parameter.
-Xmx maximum-heap-size [ k | m ]
maximum-heap-size
Sets the maximum size of the memory allocation pool, which is the garbage
collected heap, to maximum-heap-size that must be greater than or equal to
1000 bytes.
k
Sets the value to be read in kilobytes. If neither k nor m is specified, the
value is read in bytes.
m
Sets the value to be read in megabytes. If neither k nor m is specified, the
value is read in bytes.
In Example 3-1 the maximum-heap-size is being set to 64 MB, which
indicates the maximum heap size that can be used.
