4.3 Verify Core File
Before you proceed further, verify that the core file, core, is complete and valid. You can do this
in two steps.
First, open the file in gdb and check the error and warning messages.
$ gdb /opt/java1.4/bin/PA_RISC2.0/java core
HP gdb 5.5.7 for PA-RISC 1.1 or 2.0 (narrow), HP-UX 11.00
and target hppa1.1-hp-hpux11.00.

..
Core was generated by 'java'.
Program terminated with signal 6, Aborted.
#0 0xc0214db0 in kill+0x10() from ./libc.2
From the output above, you can tell that core file is valid.
Second, check that the core file was not truncated by issuing the “what core” command and
searching for the existence of the dld.sl version at the bottom of the output:
$ what core

If the dld version is displayed at the bottom of the output, the core file is valid.
4.4 Debugging On Same System
If you are debugging the core file on the same system where it was created, you do not need to
perform the steps outlined in the “Packaging Files For Debugging On Different System” and
“Unpacking Files On Debugging System” sections. Instead, proceed to the “Example gdb Session”
section.
4.5 Packaging Files For Debugging On Different System
If you will debug the core file on a different system than the one where it was created, you need
to collect problem data essential for analyzing the core file.
Collect the following items:
