How to collect relevant data for application core analysis

Not sure if you knew already - there is a tool available which collects all relevant data for analyzing application cores, for example by Sun's service and support engineers. It's called pkgapp (not pkgadd ;-) ) and can be directly downloaded by clicking this link.

When started (after extracting in a directory like /opt/pkgapp) using:
$ /opt/pkgapp/pkgapp -c /path_to_core_file -p /path_to_executable

it collects all libraries for that executable, several proc tool outputs, and more, and packs it into a tar file in a new directory below the current directory.

If you would like to test it, you can just create a core with the gcore command:

$ gcore PID

Where PID is the process ID of a currently running process for which you would like to create the core file. The process will not be killed; it will continue running.

A sample session looks like the following (hostname and hostid replaced by dummy entries):

$ id
uid=0(root) gid=0(root)
$ /usr/bin/sleep 30&
[1]     17825
$ gcore 17825
gcore: core.17825 dumped
$ /opt/pkgapp/pkgapp -c core.17825 /usr/bin/sleep
