RE: History points

[Johnson,Alex]

If you are using the "IA Series/data/legacy/old" Historian, choose the
'Config>Historian>Data_Display' pick from the menu bar when in the
Proc_Eng_Env.

If you are using AIM*, you can use some of the tools it provides to examine
data, but it is not particularly user friendly.

There are a variety of programs available to extract the data and put it in
a file which can then be viewed.

My favorite (since I wrote it and get paid for it) is Extract, but there are
others.

Hi foxboro list,
How can I read the history information like Hourly average for a

Any help or suggestions will be greatly appreciated!

Yes, Under Solaris /tmp is a tmpfs which means it is a RAM disk.
Anything file copied to /tmp will consume RAM/swap by the same size of
the file. I have seen many times commercial applications use /tmp for
logs on Solaris (probably just ported the app from another unix). When
the logs grow the machine groans.

Logs on Solaris should be written to /var/tmp which _is_ disk based.
/tmp should be used for small files that need fast access.

use du -s /tmp/* to find if the space is used on /tmp

RE: How do I turn off swap

[Bruley,Peter]

Good idea Alex

There is also another version of ps that lives in /usr/ucb (University
California Berkley) that will accept the options -vx.

Ie: /usr/ucb/ps -vx this will
sort the processes by  memory/cpu usage in the following format:

PID TT   S  TIME SIZE  RSS %CPU %MEM COMMAND

There is also a program kicking around called proctool that has some fancy
graphical gui's to show you what processes are hogging all the memory/cpu
time. 

But like Alex says it all boils down to the same thing in the end:

 "BUY MORE RAM"

Hello,

You might want to make sure a third party program is not
leaking memory and consuming your swap space.

Watch programs memory usage over the period in question
and see if this might be the problem.
