Hi,
I am having memory problem. Whenever i run the Tivoli backup command from CLI "dsmc" my memory use is very high.
Topas shows the following output Memory
Real, MB 35584
%Comp 17
%Noncomp 80.1
%Client 80.1
and "svmon" shows
Paging space has not been used size inuse free pin virtual
memory 9109504 8979484 199652 643070 2828204
even after the command is finished the memory is not flushed. If i restart the machine memory use comes to normal and after the using "dsmc" problem comes again
when the command is running
svmin -P <PID of dsmc>
shows huge amount of memory use
but when the process is finished no more process remains ps -ef | grep dsmc doesnot show any process
but the memory is not flushed

Having used up so much memory is totally normal on AIX since AIX uses the free RAM to cache files so it has not to read the files from "slow" physical disks again in case they will be needed.
Also you see that the ratio of your

%Comp 17
## vs ##
%Noncomp 80.1
%Client 80.1
is quite good. Comp is Computational Memory which is processes, ie. running programs etc. using memory. Noncomp (&Client) or Noncomputational Memory is usually cached files which can be flushed ie. cleaned up by LRUD if not used.
Other terms for them are Working Segments and Persistent Segments. Working is the programs etc. in memory, persistent are files on/from disks etc.
To see if you really have a problem on your box I'd recommend that you might fire off a
Code:
vmstat 1 10
at your peak times when you assume there is lot's of traffic.
As a start and regarding memory you might want to check the columns for pi and po. Or just post it here so we can see it.
If you have restarted the system AIX doesn't even have something to cache which would make sense, why it isn't using the memory even as filecache. When running a backup job with ADSM you shove a lot of disk data through memory and now the kernel has at least *something* to put into filecache - therefore it remains there until changes in your file utilization come up (via usage of different files, etc.). This is the reason the non-comp memory never goes back to 0%.
Let's say i have 20 users logged on Server. How can I know how much memory percent used each of them is using with system time in each user? (2 Replies)
Hi all,
Can you please tell me the command, with which one can know the amount of space a specific directory has used.
df -k . ---> Displays, the amount of space allocated, and used for a directory.
du -k <dir name> - gives me the memory used of all the files inside <dir>
But i... (2 Replies)
Hi,
I'm running a multi-process software system on a Solaris 8 machine. When I monitor the memory usage, I see that the free memory is dropping rapidly, but I can't detect a process that uses this memory.
I'm using "top" to get the free memory and the memory usage of processes.
Thanks. (3 Replies)
