Can a coredump be different name?

Godfrey Zhang — Wed, 26 May 2004 21:04:49 GMT

We have a server recently crashes very often, we wanted to have multiple coredumps with differnt names for analysis, so we created multiple dump lvols. Can we have different coredump names? Thanks.

If you are not going to fix the crashes (loading the current patches should take care of that) then there is no reason to keep the crash dumps at all. Just remove all the crashdumps, then remove the /var/adm/crash directory. Now when your system crashes, it will reboot faster and not create any crash dumps.

The application which ever is dumping core if that can be modified a bit, then this can be possible.

This can be done by adding a signal handler to the application. In the singnal handler you can use rename(2) to change the name of the core file.

Thanks Bill and Anupam, I've written a script monitoring the core file, once it finds a new core file then it renames it to another name. Thanks for your clue.

There is a kernel parameter, core_addpid, that
can be set to automatically add the pid to the
name of each core file. See this thread-
