Hi,

I found the core dump size is very large in my workstation, would someone tell me how to set the coredump size?

Thanks a lot .

Hi, Zhiyong,

The core dump size is largely dependent on the size of the program that was in resident memory. In saying that, there a couple of ways in which you try and manage it.

Core dump from system panic. You should leave
this, as it can be analysed later to specific
problems. Have a look at the man page for 'savecrash'

Core dumps from applications. Use can use the
'setrlimit' program. Have a look at the man
page for this. You can also look at the 'ulimit' program. For example if you wanted to set a core limit for a child process you could use 'ulimit -c 4096'

Miachel is right.

For a program you can change it with ulimit command. But ulimit command varies with shell.
in bash U can see it ulimit -Ha -Hard limits
ulimit -Sa -soft limits

For HPUX - and posix shell the ulimit command is used to limit user resources

If you specify the -a switch it lists current resources

ulimit -a

If you don't want to create a core file of larger than 1024 blocks, use the following

ulimit -c 1024
