HP tune for Websphere application

Hi all,
Need help on how to change this value at HPUX 11.23 server installed with Websphere appl version 6.0.2.17

a). Java virtual machine (JVM) virtual page size
1. Description: Sets the JVM instruction and data page sizes to 64 MB to improve performance.
2. How to view or set: Use the chatr +pi64M +pd64M /opt/WebSphere/AppServer/java/bin/PA_RISC2.0/native_threads/java command. The command output provides the current operating system characteristics of the process executable.
3. Default value: 4 MB, if not assigned
4. Recommended value: 64 MB

permanently need to set this value in /etc/rc.config.d/nddconf
ndd -set /dev/tcp tcp_keepalive_interval 15000

You might get more and better answers in an
HP-UX forum than you will in this VMS forum.
