Application programming: z/OS.e does not run the following types of
applications: CICS, IMS, COBOL (with an exception),
Fortran, and PL/I
(with an exception). The COBOL exception is that
precompiled COBOL DB2
stored procedures and other precompiled applications that use the
Language Environment preinitialization interface (CEEPIPI) are
supported. The PL/I exception is that precompiled PL/I
applications
are supported. These COBOL and PL/I applications could be
compiled on
a z/OS system, then run on a z/OS.e system. </quote>
Does this mean that C/C++ compiling and executing - no matter
what - is
fair game on z/OS.e?
To our USA readers - my heartfelt wishes for a wonderful Thanksgiving
holiday.

From what I can tell, you may compile and run C/C++ programs on z/OS.e
with no restrictions (assuming you have licensed it). I looked in the
IFAPRD00 member that came with z/OS 1.6 (which has a z/OS.e section in
it). There is an entry for the C/C++ compiler in that section.
Therefore, I assume that it is possible to license the C/C++ compiler on
z/OS.e
This makes sense because z/OS.e is for "non traditional" workloads. The
way that I read IBM's intent is that z/OS.e is mainly to support a
Websphere / DB2 environment for "e-business". Websphere almost demands a
C compiler for applications.
IBM's intention is quite obvious here, although not clearly expressed.
z/OS.e is to compete with another "e-business" platforms. For customers,
which have (yet) choice, what platform should be better in terms of TCO.
CICS, IMS, & other "traditional" workload users don't have such choice.
They're already in deep s*t, they caught.
Obviously (maybe not for IBM) z/OS.e is very interesting mostly for
existing mainframe users, thos fighting for lower TCO. Some of them
decide to change the platform (see MMA, or other ideas), or they try to
(we call it catch left ear with right hand) "wangle" how to fit in terms
and conditions of z/OS.e. I know some customers which dropped CICS
giving place for replacement product (there are such).
Solution for that situation was mentioned hundred of times: make
software fees lower. Mainframe software is too expensive.
