kdb should work for both - and is included in AIX automatically. There is a "SERVER" mode kdb (only in maintanence mode I think. There is somethiong to make is 'special') appropraitely named KDB (all caps).

dbx is, I assume, the preferred debugger by app developers. But once you get into application development you must also be aware of  java debuggers, or any other interpreted application environment. Otherwise you just have a core dump of the "engine", not the application you are working on.

As a category, these tools are known - in IBMSpeak - as ADE - Application Development Environment ( http://www.pcmag.com/encyclopedia_term/0,2542,t=ADE&i=37532,00.asp ). More recently the DK names are being used - or XXX Development Kits.

Thanks for the update! Reminders help!

Been a long while.

The basic command you will want is 'kdb' - kernal debugger.

The most basic commands to see what is in the dump are:

stat
status
errpt

and dont forget help.

There is a redbook, not sure how current - and I'll have to look up the number.
