gdb and other tools ?

[Shivkumar]

Hi,

I am aware of a debugging tool like "gdb" on HPUX to debug applications such as Apache, WebLogic etc.

What are the other available similar tools on HPUX ?

Thanks,
Shiv

gdb is the main tool used for that.

if an application is hanging, I have seen some customers TOC the box and use q4 to see what is going on (more for device drivers) and such.

Hi Shiv,

The binary adb is the built-in HP-UX debugger.

HTH,

also of interest http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/tusc-7.8/

Tusc traces the system calls a process invokes and the signals it
receives. It displays arguments in a symbolic way, shows the first
bytes of read and write buffers as well as signal information when
available. Tusc can attach to live processes by providing PIDs
(process IDs) as argument(s).

'lsof' saved me from some nightmares probably more often than gdb and truss/tusc together.

Debugging is a hard job, the prefered tool depends on the program/script/application/system behaviour you want to "debug".
You have to understand the language of the system in every case.

For your own programs the best may be gdb, for scripts perhaps just set +x and many applications brings their own debugging tools.

It really depends on what kind of problem you want to debug.

Hi Shiv,

Prefer to use HP's WDB which is based on GDB and ported to HP-UX, fully supported by HP.

You can download it for free from,

http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,1662,00.html

Other debugging tools are,

"tusc", sometimes adb.

Hi Arun,

How to install and use wdb ?

Thanks,
Shiv

[Shivkumar]

What is q4 ? Can someone describe the use of it ?

Thanks,
Shiv

[Arunvijai_4]

Hi Shiv,

Once you download wdb, you can install it using "swinstall".

# swinstall -s wdb

Second question,

"q4" is used to analyse live kernel, You can find docs at /usr/contrib/doc/Q4Docs.tar.Z.
