Hi Satoshi,
The startup, kill scripts should be placed in /etc/rc.d/rc3.d/ , /etc/rc.d/rc6.d/ respecive folders and also make sure that If you application relies on libraries then make sure PATH and LD_LIBRARY_PATH environment variables set to the required libraries.
BTW is your application coming to online after 8 minutes
Thanks,

Thank you advice. Yes my app is coming to online less than 1 minute.
Including AXP OS startup, about 3 minutes are spent for boot up my app.
