Nonstandard Java Options
The nonstandard options are:
-Xssn
Sets the thread stack size.
Every thread spawned while a Java program runs has its own stack. This thread stack is shared
by Java program code, any native (JNI) code, and the Java VM code. The default stack size is
512 kilobytes (-Xss512k). You can use this option to increase the stack size if you experience
stack overflow exceptions. The default units for n are bytes; n must be greater than 1000 bytes.
To modify the meaning of n, append either the letter k (or K) to indicate kilobytes, or the letter m
(or M) to indicate megabytes. For example, –Xss10240 and –Xss10k are equal.
-Xincgc
Specifies using the incremental low-pause garbage collector. This option is supported but using it
can lead to about a 10% decrease in garbage collection performance.
Deviations from Nonstandard Java Options
-Xmsn
Specifies the initial size, in bytes, of the memory allocation pool. The default value is implementation
specific; the value is about 3.6 megabytes.
HP Extensions to Standard Java Options
-nsjversion
Prints the NonStop Server for Java 7.0 build version.
