The whole purpose of the disk cache in HP-UX kernel is to make sure the memory usage is 100%. Which kernel parm did you reduce? The disk cache ones?

dbc_max_pct from the default 50 to 10
dbc_min_pct from the default 5 to 2

>dbc_max_pct from the default 50 to 10

Yes, this will reduce the size of the disk cache. What do you intend to do with the machine? I.e. if you intend to use Oracle, reducing the disk cache is a good idea. Otherwise it may have a negative effect.

>i want to know are the HP sim use high memory or not?

Your 100% or 50% memory use was due to the disk cache. Why not put your application on the server then measure the performance.

Julianto,
normally startup/stop scripts while system booting on HP-UX are under directory /sbin/rc*.d. For HP SIM startup script should be in /sbin/rc2.d. You can find this script by run command ll /sbin/rc2.d/*hpsim. After you find that script you can stop this process by run command /sbin/rc2.d/S*hpsim stop.
ex. /sbin/rc2.d/S910hpsim stop
