how to determine which application created the OS core file in AIX

To determine which application created the OS core file in AIX:

# /usr/sbin/lquerypv -h /path/to/core 6b0 64

The output of this command is neat, clean and easy to read. Here is an example:

# lquerypv -h core 6b0 64
000006B0 7FFFFFFF FFFFFFFF 7FFFFFFF FFFFFFFF |................|
000006C0 00000000 000007D0 7FFFFFFF FFFFFFFF |................|
000006D0 00120000 1312C9C0 00000000 00000017 |................|
000006E0 6E657473 63617065 5F616978 34000000 |netscape_aix4...|
000006F0 00000000 00000000 00000000 00000000 |................|
00000700 00000000 00000000 00000000 00000ADB |................|
00000710 00000000 000008BF 00000000 00000A1E |................|

The executable is located between the pipes on the right hand side of the output. In this case, the core was generated by Netscape. 

Example:

/usr/sbin/lquerypv -h /tmp/core 6b0 64
