Regarding "Available Memory"

[Kavita Poonia]

Hello everyone,

I know how to find out physical memory on HP-UX server through Glance or command print_manifest|grep -i mem but there is also "Available Memory", which I wanted to know but do not know the way to find it.

What's your definition of "available" memory?
Are you talking about swap or RAM?
Do you care about memory used by the disk cache that can be reused for something else?

hi Kavita,

There is also one useful utility that can help you view your memory status.

e.g.
SRV2:>./mem_details
Memory Stat total used avail %used
physical 8192.0 1446.8 6745.2 18%
active virtual 1226.9 1044.3 182.6 85%
active real 412.6 296.5 116.1 72%
memory swap 6309.9 223.0 6086.9 4%
device swap 10240.0 461.4 9778.6 5%
Activations: 0 total, 0 rate. Deactivations: 0 total, 0 rate.
Reclaims from Swap: 12743101 total (Up 0), 5 rate.
SRV2:>


this was written by Scott Robertson and the attached C source must be compiled on your system using the following command:

cc +DD32 -D_PSTAT64 mem_details.c -o mem_details

hope this helps too!

A good explanation of various mem management user concepts can be found here: http://docs.google.com/View?docid=dc7s6mzr_56cgsg9g

you can use the

# cstm

# sel dev " Mem"

#il

This will show you the information about the physical memory on your system
