Note: A table is shown in each option description. It summarize whether the product is
included with the operating system automatically or if it must be ordered separately. The
status states if the product is a chargeable or a no charge feature.
System Openness Includes (5722-SS1 Option 13)
The functions in System Openness Includes are based on industry standards from Portable
Operating System Interface (POSIX) and the single UNIX specification. These standards
enable source code portability of applications over platforms such as OS/400, OS/2, AIX,
MVS and other non-IBM operating systems.
Pthread (POSIX-based) APIs are included in OS/400 as Option 13 System Openness
Includes. They allow Business Partners or iSeries application developers to take advantage
of new system support for kernel threads. Creating an iSeries thread is faster than creating
an iSeries job and is a more efficient way to spin off portions of application or server
processing into parallel tasks.
The Pthread APIs are based on open APIs described in the ANSI/IEEE Standard 1003.1,
1996 Edition (also known as ISO/IEC 9945-1: 1996) and the Single UNIX Specification,
Version 2, 1997 standards.
Note: These APIs previously shipped as PRPQ 5799-XTH.
Media and Storage Extension (5722-SS1 Option 18)
For software developers who want to customize their own storage management applications,
Media and Storage Extensions provides an API to enable application monitoring and control
of media usage, including volumes to be selected and volume expiration dates. The API also
enables fast search for IBM 3480, 3490, 3490E, and 3575 tape drives.
