Using PROSTACK to produce a readable stack trace
This KB explains how to use PROSTACK to produce a readable Stack
trace for any Progress executable that produces a core file.
For the _progres, where a core file has been generate for example,
start progress and run this command :
prostack -r $DLC /bin/_progres <core file>
You will get a menu screen where you will be prompted to type your OS.
For an ALpha, you type 1 for example.
You will then have to comfirm this option you typed in with a y.
Log messages will be displayed and these files will be created:
dbx.log
dbx.script.tmp
and possibly
protrace.<pid>
These files are what we need.
This is how a stack trace was created on an Alpha machine:
prostack -r $DLC/bin/_progres <corefile>
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
'uname -a' for your machine indicates: OSF1 tsaxp1 V3.2 41.64 alpha.
Select the option which best describes your UNIX machine:
1. AlphaOSF1: Digital Alpha OSF/1
2. DGUX: Data General AViion
3. HPUX: Hewlett Packard
4. AIX: IBM RS6000
5. ICL
6. SEQ2: SEQUENT ptx/2.0
7. SEQ4: SEQUENT ptx/4.1
8. SCO: Santa Cruz Operations
9. SGI
10. SunOS
11. UnixV4: NCR or Unisys UNIX 5.4
99. exit
Option: You selected 'AlphaOSF1' to describe your system. Is this
correct (y
)?

The following debuggers are available through the
'DEC OSF/1 Operating System' (OSFBASExxx) software subset:
/usr/bin/dbx
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Using the dbx debugger to produce a stack trace from an image file:
/usr1/v73E/dlc/bin/_progres
and core file:
core
Appending output to file dbx.log...
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
This is how the files should appear:
dbx.log:
Date: Tue Nov 25 14:52:45 MET 1997
Debugger commands:
/usr/bin/dbx /usr1/v73E/dlc/bin/_progres core << END_OF_INPUT
where
quit
END_OF_INPUT
Stack trace:
