Re: C++ Workable Mainframe Debuggers

I have been using z/XDC to debug C++ for years (before it was even
called z/XDC). Of course, you have to be able to read assembler to do
so without any source code support. The assembler listings from the
compiler are pretty much the same as any assembler listing and the
compiler code generation becomes quite familiar after awhile.

If you developers don't know assembler very well, this may not work for
them.

Does "C Source code support" also mean C++?

Cole Software's z/XDC - no

We are on the verge of publishing C Source code support ("c/XDC") to
beta testers.

More soon.

If you're debugging C/C++ on z/OS:

1. There's dbx for UNIX System Services (only):

No charge.

2. IBM Debug Tool for z/OS is available. IBM has introduced a new
version
annually for years now, so you want to stay current and take a fresh
look
if you remember an old version. Version 7, in particular, introduced
some
substantial C++ related improvements. Version 8 is current. I see a lot
of
old Debug Tool installed out there, unfortunately.

You can license Debug Tool as MLC or, in the form of the Debug Tool
Utilities & Advanced Functions superset product, as OTC with
subscription.
As you prefer.

Unfortunately for z/OS 1.5 you'll be limited to Debug Tool (or DTU&AF)
Version 7, so please try to get your z/OS release updated as soon as
you
can, at least for the development LPAR(s) where you're most likely to
be
debugging. You may be able to work with IBM to order DT or DTU&AF
Version 8
and arrange temporary use of Version 7; can't hurt to ask. Actually, as
I
write this Debug Tool V7 MLC is still orderable so no harm there, but
for
reasons of subscription you'll want to order DTU&AF V8 if you go the
OTC
route.

For graphical debugging use Rational Developer for System z (or
WebSphere
Developer Debugger for System z) in conjunction with Debug Tool (or
DTU&AF). I think those tools also provide graphical debugging with dbx
now.
Very slick.

A certain popular IBM-MAIN training firm has a course on C/C++
debugging.
Details here:

http://www.trainersfriend.com/C_courses/N735descr.htm

3. There are a number of commercial debugger products for z/OS, most
already mentioned. However, many (all?) of them don't support C++.
Here's
the latest information I have, and someone please correct me if my
information is out of date:

Cole Software's z/XDC - no
CA-InterTest - no
Compuware's Xpediter - C yes, C++ ?
Gary Bergman Associates' Advanced Debugging System (ADS) for CICS - C
yes,
C++ ?
Macro4's Tracemaster - no
MacKinney Systems' Track and Xray - no
ASG's (formerly Viasoft's) SmartTest - no
Serena's StarTool ATD - product withdrawn?
