telnet client problem 1

[gpetrom]

Hi
I have a proliant ml370 with sco open server v5.0.4 and my company is using telnet client to logon.They are using a Cobol program and sometimes with no particularly reason the program closes in more that one users at the same time.
Can anyone ever had such an experience, can I increase the memory that clients are using and how can i see how much
memory is using the server

Thank you all in advanced

You can watch server memory use with this command:

# sar -r 2 50 (display every 2 seconds for 50 iterations)

What gets displayed is in 4K hunks (I think). You can run this and log another use onto the system. You should see a drop which indicates how much memory each user consumes just starting the application.

You can also get a picture of each processes' memory consumption with:

# ps -ale

The SZ column is memory allocation (again in 4K hunks, I think).


Are the users who get disconnected active or idle?

Hi motoslide
Thank you for replying
Yes they are active and that is the problem.
Do you believe that the problem is that I have an old UNIX version, I have read in another thread that 5.0.5 has problems with xeon cpu what is your opinion about that?

For a Xeon (or P4) machine you need at least 5.0.6a.
The risk is to damage the CPU due to overtemperature.

Hope This Helps, PH.

You never had a PANIC message on the console nor the server rebooting randomly ?

Hope This Helps, PH.

No never as i said sometimes users are disconnected from unix

You may take a look at the output of this command:
netstat -m
the fail column should always be 0 (zero) and the maximum streams memory used should not reach the total configured streams memory.

Hope This Helps, PH.
