NonStop Server for Java Tools Reference (NSJ 4.0+)

-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; their
implementations are a typical Java implementation.
-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,
–Xss10000 and –Xss10k are equal.
-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
option is not supported on this platform.
-XX:+UseParNewGC
Specifies a parallel garbage collection. This option is disabled. If you specify
this option, the Java VM exits with the error: -XX:+UseParNewGC option
is not supported on this platform.
-XX:+UseAdaptiveSizePolicy
Specifies an adaptive size policy. This option applies only for a parallel
collector and, therefore, is disabled. If you specify this option, the Java VM
exits with the error: -XX:+UseAdaptiveSizePolicy option is not
supported on this platform.
-XX:+AggressiveHeap
Obtains the platform resources and configures the heap layout accordingly,
uses parallel collector, and enables AdaptiveSizePolicy option. This
option applies only for a parallel collector and, therefore, is disabled. If you
specify this option, the Java VM exits with the error:
-XX:+AggressiveHeap option is not supported on this platform.
