Development Environment
NonStop CORBA applications are implemented by Open System Services (OSS) processes in the OSS
environment of the NonStop Kernel operating system. The OSS environment coexists with the Guardian
environment and provides an independent alternative to it. OSS conforms to open computing industry standards,
specifically to the POSIX.1 (API) and POSIX.2 (shell/commands) standards. The OSS environment provides a
UNIX® personality to the NonStop Kernel, but unlike UNIX, OSS is not an operating system. The NonStop Kernel
is the operating system for both the OSS and the Guardian environments.
OSS consists of the following major components:
File system: the OSS file system has a hierarchical structure similar to that of UNIX, composed of directories,
subdirectories, files, and pseudo-files such as links and pipes. The OSS file system uses the flat Guardian file
system.
●
Application programming interfaces (APIs).●
Run-time libraries.●
Command interpreter (OSS shell): the OSS shell is a POSIX.2-compliant command shell that is based on the
Korn shell.
●
User commands and utilities.●
The osh command enters the OSS environment and starts an OSS shell process.
To work with NonStop CORBA, you need to have a basic understanding of the OSS environment and you need to
know how to use some of the OSS commands. A few of the commands most used in preparing a NonStop CORBA
application are described in the following sections. For more complete information about programming in the OSS
environment and OSS commands, consult the Open System Services Programmer's Guide and the Open System
