100% memory usage in prstat

Hi Guys,

I have observed the Oracle (DB USER) is utilizing 100% of the memory in the prstat -a output. I am bit confused is it normal and if not how to bring it down? ABout the machine it is a SunOS 5.10 Generic_125100-10 sun4v sparc SUNW,Sun-Fire-T200.

Please see below output of prstat -a
I have made bold the utilization...

Code:

topsysproc

topsysproc(1m)							   USER COMMANDS						    topsysproc(1m)

NAME

       topsysproc - top syscalls by process name. Uses DTrace.

SYNOPSIS

       topsysproc [-Cs] [interval [count]]

DESCRIPTION

       This  program  continually  prints  a  report of the number of system calls by process name, and refreshes the display every 1 second or as
       specified at the command line. Similar data can be fetched with "prstat -m".

       Since this uses DTrace, only users with root privileges can run this command.

OPTIONS

       -C     don't clear the screen

       -s     print per second values

EXAMPLES

       Default output, 1 second updates,
	      # topsysproc

       Print every 5 seconds,
	      # topsysproc 5

       Print a scrolling output,
	      # topsysproc -C

FIELDS

       load avg
	      load averages, see uptime(1)

       syscalls
	      total syscalls in this interval

       syscalls/s
	      syscalls per second

       PROCESS
	      process name

       COUNT  total syscalls in this interval

       COUNT/s
	      syscalls per second

NOTES

       There may be several PIDs with the same process name.

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       topsysproc will run until Ctrl-C is hit.
