UNIX for Dummies Questions & Answers

Hai ,

I am working on a system with unix and solaris 5.8 loaded.

The problem is when I leave an application open for more than one day .. it gets killed .. and my one day work goes waste and I have to start all over again .. ???


Is there any way I can find out the maximum number of hours that a process can run using some command ??


Thanks in advance

What type of application is getting killed? What is the message you get when the application is killed? Are you using a terminal window or GUI?

Without more information I am guessing any of the following could potentially be your problem.

1/. The application is running out of available open files
2/. A firewall or network device is dropping the session
3/. You are exiting the shell and the process dies.

I would suggest you find out what the error message is and then we can start some trouble shooting...

hai,

The application I am running is a simulator for a network switch. The GUI is built using TCL/TK and it executes C programs in the background .

The problem is the Gui works fine but the background C program is getting killed ..??

As for error message I am not getting any ???

Is there any way the admin/ root user can specify the maximum number of hrs a process can run . ??? If there is how can I see the specified limit set by the root / admin

Is there any activity to the application when that "C" program is killed ??
Does it generate any "core" file ??

Hai,

No there is no core dump generated .

Try "ulimit -a" to see all of your limits. This is usually a shell built-in and you may need to try various shells. bash is good. There is a cpu second limit that can be set. This should display it. Also read "man getrlimit".

hai,

thanks a lot Perderabo. I will try to change the CPU limit and see it my application is working more than a day .
