There are various tools to monitor various aspects of performance.
http://docs.hp.com/index.html
By the way, that's 'ipcs' not "ipca" and it's 'HP-UX' not "hpuxx".

SolutionWe could also find the Free Memory via this command
Refer http://docs.hp.com/en/B3921-60631/top.1.html
glance >> Glance is a performance monitoring tool which is used to see the CPU/DISK/NETWORK/MEMORY Utilization.
https://h10078.www1.hp.com/cda/hpms/display/main/hpms_content.jsp?zn=bto&cp=1-11-15-28^9637_4000_100
vmstat >>
In vmstat you could look for the any page-out(po) which are taking place.
There should always be less than a single digit page-out. 0 page-outs are best
sar >> This is used to see the CPU utilization(sar -Mu 1 1), Buffer utilization(sar -b 1 1), Disk Util(sar -d 1 1)
You could refer to http://docs.hp.com/en/B3921-60631/sar.1M.html
ipca (It should have been ipcs)
This report status of interprocess communication facilities. It is used to see the size of the shared memory segments, and also we could check the attached processes.
Also we can see which shared memory segments are marked for DELETE.
Refer to http://docs.hp.com/en/B3921-60631/ipcs.1.html

Re: purpose of top, glance, vmstat, sar, ipca in hpuxx
All these are using for performance monitoring.
top will give an o/p which contains a list of the processes using more CPU.It also show the memory informations.
vmstat is used for virtual memory performance.
sar-system activity reports can be used to check the performance of CPU,memory,disk etc
Anyway it is better to search in man pages.

It looks you are started learning HP-UX. If so I would suggest the following book to give you very best basic knowledge on HP-UX.

Re: purpose of top, glance, vmstat, sar, ipca in hpuxx
This sir is why we have man pages.
Each command has an explanation.
top - to measure performance and system load
glance - a proprietary tool from HP that provides more detail.
vmstat - swap use and performance
sar - performance measurement, free, very useful.
