Automatic renaming of core dump file

[dscao]

Is it possible on HP-UX to automatically rename the core file of an app coredump? So that successive coredumps get saved on the system, rather than that only the last one is retained.

You could set up a cron job that would do a find, searching on the name core and then renaming it to core.`date` or something like that.

Hi:

If you want to name a corefile uniquely you can append the process id (pid) thusly (by setting the 'core_pid' kernel variable:

For 11.00 or 11.11:

# echo 'core_addpid/W 1' | adb -k -w /stand/vmunix /dev/kmem

For 11.23:

# echo 'core_addpid/W 1' | adb -o -w /stand/vmunix /dev/kmem

Regards!

Rename the core file so it is unique and see if this does the trick for you:

# mv core core__$$

the $$ makes the filename unique as it's the pid of the subshell in which the command is executed.

Thanks to all.

11.31 has a coreadm command so you don't need to use adb.

Hi Dennis:

Thanks for the 11.31 info. From some cursory reading and tidbits like those you have provided, I would say 11iv3 has some really NICE features.

You can look at all of the 11.31 documentation:

And Chapter 3 has what's new:
