UNIX® Certification UNIX® certification provides a vendor-neutral, highly regarded, and global benchmark for identifying open operating systems. Only systems that are fully compliant and certified according to the Single UNIX Specification are qualified to use the UNIX® trademark. Advantages of UNIX Certification The Open Group UNIX standards offer the most stable, portable and cost-effective applications development environment for a wide range of platforms from mobile devices to mainframes. For end-user enterprises, procuring certified UNIX systems ensures the highest level of availability, scalability, and maintainability for those who want to focus on their business with confidence in their IT. UNIX certification is a trusted and open system industry standard, ensuring that products conform to the most exacting criteria for portability, compatibility, and global interoperability. This enables buyers to specify UNIX conformance in procurements, facilitates Boundaryless Information Flow™, and enhances the perception of the UNIX system as a consistently stable, flexible, and reliable operating system. Benefits for Application Developers Guaranteed consistency of services and behavior amongst UNIX® operating system implementations Improved portability Backward-compatibility Faster development through the increased number of standard interfaces More innovation is possible, due to the reduced time spent porting applications Benefits for Users An evolutionary approach that protects investment in existing systems, data, and applications The availability of UNIX systems from multiple suppliers gives users freedom of choice rather thanbeing locked in to a single supplier UNIX V7 UNIX 03 UNIX 98 UNIX 95 IBM Corporation: z/OS 3.1 or later with: z/OS 3.1 or later Security Server and z/OS 3.1 or later C/C++ Compiler on IBM Series Processors that support z/OS Version 3.1 or later IBM Corporation: AIX version 7, at 7.2 TL5 (or later) on systems using CHRP system architecture with POWER™ processors IBM Corporation: AIX version 7, at either 7.1 TL5 (or later) or 7.2 TL2 (or later) on systems using CHRP system architecture with POWER™ processors Hewlett Packard Enterprise: HP-UX 11i V3 Release B.11.31 or later on HP Integrity Servers IBM Corporation: AIX 6 Operating System V6.1.2 with SP1 or later on Systems using CHRP system architecture with POWER™ processors and 2, 8 or 128 port async cards IBM Corporation: AIX 5L for POWER V5.3 dated 7-2006 or later on Systems using CHRP system architecture with POWER™processors IBM Corporation: z/OS V2R1 or later with: z/OS V2R1 or later Security Server and z/OS V2R1 or later C/C++ Compiler on IBM zSeries Processors that support z/OS Version 2 Release 1 or later The SCO Group, Inc.: UnixWare ® 7.1.3 and later for single and multiprocessor systems based on IA-32 and compatible processors and conforming to PC architecture The SCO Group, Inc.: SCO OpenServer Release 5 and OpenServer Release 6 on Single and Multi-processor Industry Standard Intel architecture platforms UNIX® and the Open ‘O’ and Check Certification Mark logo® are registered trademarks of The Open Group.
