Disclaimers
I use the term 4GL not ABL
The code examples in this presentation
are character style (i.e. non-OO) because
it makes it easier to use a larger font and
fit the example on a slide
The Application Profiler (AP) is not
supported by PSC
However I have never heard of anyone
having issues with it

History
Added by Tim Sargent in 1999
Initial Version - Progress V8.2A
Still works as of V11.0
However the AP has not, to my
knowledge, been enhanced in any
meaningful way since V9
Initially used a ‘zecret’ startup option
(-zprofile)

AP Basics
Old Location:
$DLC/src/samples/profiler
Current Location: “Documentation CD”
Excellent documentation (readme.doc)
by the author
Requires a GUI (prowin32.exe) license
to use the supplied code
But the code being profiled doesn’t
need to be GUI code

AP Replacement
An updated version of the AP called
“Profiler Control Tool” is available on
Progress Communities:

What Is Application Profiling?
“A performance profiler is a common
and useful tool for a software developer.
In brief, a profiler provides a “profile” of
a particular execution. A profiler
generally provides timing information
and call-tree information; with that, an
engineer can analyze where their
program is spending most of its time
and what part of the application is
calling what other part of the
application.”

AP Basics
Two Main Parts
Generating the Profiling Statistics
Analyzing the Profiling Statistics

AP Getting Started
Client Startup Option:
-profile <profiler-config-file-name>
Minimum entry in the Config file is:
-filename <name-of-output-file-for-stats>
There is also a PROFILER System
Handle that can be used to specify the
equivalents of the command line
options
10
PUG Challenge 2012
Other AP Options
-listings <directory> will attempt to
create COMPILE DEBUG-LISTINGs for
the code being Profiled IF the source
code is available in PROPATH
This is a highly recommended option
But if the PROPATH for the Client
(probably using R-code) being
profiled is different than the
PROPATH for the source…watch out
