Shalom,

HP-UX crashes are in /var/adm/crash and require q4 analysis.

Re: Need docs on Crash analysis of Application dump cores and HPUX crashes

SEP has given you links on kernel panics.

For application aborts, you may want to look at the documentation with WDB:

Hi Novonil,

The HPUX user space debugger team is in the process of coming up with a white paper on application core file debugging on HP-UX. Meanwhile, I hope the attachment here will be helpful to you. This describes the HP gdb commands that can be used for corefile debugging.

Re: Need docs on Crash analysis of Application dump cores and HPUX crashes

Hi Novonil,

Starting with WDB 5.6, you can also connect gdb directly to an application, by either starting it as

$> gdb -crashdebug [...]

or attach to a running app as

$> gdb -crashdebug -p

If the process ever crashes, it will attach debugger prior to the point of crash and then you can use the gdb commands as described earlier.

What is the nature of your problem?

Cheers!

Re: Need docs on Crash analysis of Application dump cores and HPUX crashes

Hi All,

Thanks for all those inputs.

Really Gr8 feedback from you guys on Application core dump analysis which i was not aware of.

Infact i am aware that HP 11.31 is coming up with crashinfo tool included in its release which will solve a lot of debuugging issues.. But i want to fully understand the crashinfo output which is very long..

Can any one help me witjh a doc which tells about the crashinfo output and how to read the same ?

Unless you are making kernel drivers, crashinfo won't help for application issues.
