NonStop Server for Java Tools Reference (NSJ 4.2+)

-d32
-d64
Selects whether the program is to be run in a 32-bit or 64-bit environment.
Note: These options are not valid with NonStop Server for
Java 4, which uses only the 32-bit environment to run Java
programs.
Nonstandard Java Options
The following nonstandard options are shown for your convenience.
-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 128 kilobytes (-Xss128k). 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.
Deviations from Nonstandard -XX Java
Options
-XX:+UseParallelGC
Specifies a parallel garbage collector. This option is disabled. If you specify
this option, the Java VM exits with the error: -XX:+UseParallelGC
