C/C++ Applications on z/OS and OS/390 UNIX

In this IBM Redbook, we focus on how to move applications written in C/C++ from other UNIX operating systems to z/OS UNIX System Services. We highlight the traditional strengths of z/OS, and describe some of the subsystems not always found on other UNIX variations. We address application development tools, the C/C++ compiler, and open source development code such as the C++ Standard Template Library (STL) and the Adaptive Communication Environment (ACE). We also suggest some performance tuning techniques.

Finally, a real world port of a C/C++ application is detailed. First we describe the application itself, and then discuss the following aspects of the port:
Before What we did to set up the application development environment
During Which issues we encountered while porting to z/OS
After How we tuned the application once it was running
In conclusion, we summarize our overall findings. Many additional appendixes are included for reference such as:
- A comparison of z/OS and GNU compilers and make tools
- OS/390 C/C++ compiler ASCII support
- STLPort information
- Discussion of dumps
- Performance analyzer output
- OS/390 UNIX Porting Guide - process management
