trace core file by STACKX script

I posted "How to debug core dump?". I felt curious what I can do with core dump file from oracle's process.
Thank You Roger Snowden. He suggested me stackx script. STACKX User Guide [ID 362791.1]

stackx is a shell script utility for extracting diagnostic stack trace information from core file on UNIX/LINUX platforms.

I downloaded and tested it(just test on 10g with real core dump file).

$ ls stackx1_2.tar
stackx1_2.tar

$ tar xf stackx1_2.tar

$ ls stackx
stackx

$ ./stackx
Wrong number of parameters.
Usage: stackx [debugger] <corefilename>


$ ./stackx /oracle/product/admin/orcl/cdump/core_29158/core.29158

Core stack trace extraction is supported on the following platforms:
- IBM AIX
- Intel Linux (RedHat and SuSE)
- HP-UX (10.* and 11.*)
- HP Tru64
- Sun Solaris (2.5 - 2.10)

Debuggers recognized and discovered by stackx are, in order of preferential priority:
- pstack (Solaris only)
- gdb
- dbx
- adb
