Is there a way to find out the total memory that a unix system has? I mean total memory that a system running oracle has.

Do a top command at the unix prompt
> top
Memory: 2048M real,
Tells you how much RAM you have on your system.

you can also check how much memmory is available using :
#sar -r
#man sar
will give you help pages on this.
man -k will give you related commands to a subject of your choice. e.g. man -k memmory.

Once you have eliminated all of the impossible,
whatever remains however improbable,
must be true.

TOP is not installed by default in Solaris for example.

You can also try
prtcnf|grep mem

Sorry that should be
prtconf|grep mem

I am afraid PRTCONF does not work in Solaris. It works in HP and Linux.

prtconf|grep -i mem

Strange, in my Solaris does ... try lowercase ;-)$ uname -sir
SunOS 5.6 SUNW,Ultra-4
$ prtconf|head -2
System Configuration: Sun Microsystems sun4u
Memory size: 1024 Megabytes

Yep, it worked :-)

For finding out free memory on Solaris, I've tried as suggested but it complains:
# sar -r
sar: can't open /var/adm/sa/sa06
No such file or directory
I went to the /var/adm/sa and check, there is no sa06 indeed. Do I need to do anything before I run sar -r?
Thanks,
