How to force HPUX 11.31 IA to do core dump? and how to collect the code dumps?

[Dennis Handly]

To force an application to produce a core file, you can send it a SIGQUIT.

To get a panic dump, you need to do a TOC.

I have no idea how to do that? Do you mind provide me detail steps PLEASE?

Thank You!

I mentioned two things. You need to specify what you wanted to do:
kill -QUIT PID
In the MP (use control-B on the console), use the tc command.

You can use also livedump feature of 11.31:

1-) Set the value of LIVEDUMP_ENABLED to 1 in the file /etc/rc.config.d/livedump.

2-)Start the Live Dump kernel daemon:
# /sbin/init.d/livedump start

3-)Begin the Live Dump
# /sbin/livedump -b -d START

Bishwajit,

The manual way of initiating a dump if you have an older system is to just push the TOC button or you can do a cm and then a tc on the MP console. Turn the control variable in /etc/rc.config.d/savecrash to 1 or 0 depending on if you have paging devices.
