Chapter 3 HP 3000 Operating Environment Introduction Hewlett-Packard's broad range of compatible HP 3000 business computer systems provides a single operating environment and compatible software, which increases productivity throughout your organization--end users, operators, system administrators, and programmers. The functional heart of the HP 3000 900 Series is an open operating environment that supports extensive commercial functionality and, shortly, UNIX application programming interfaces (APIs). MPE/XL, MultiProgramming Executive with Extended Large Addressing, is optimized for online transaction processing (OLTP) and business data processing, while supporting all major industry standards for portability and interoperability. The powerful combination of openness and OLTP performance and functionality makes it an ideal operating environment to drive the wide range of Precision Architecture-RISC-based HP 3000 systems. Single operating environment A common operating environment is provided across the entire family of HP 3000 systems. Upward compatibility has long been a hallmark of the HP 3000. When upgrading to larger systems, applications and data are simply stored off the old system and restored on the new system, which protects your investments in applications software and retraining end users, operations staff, and system administrators. The HP 3000 900 Series operating environment also provides application portability and broad multivendor interoperability through industry and de facto standards. Superior performance MPE is optimized for high performance in I/O-intensive online transaction processing (OLTP), multibatch, and general purpose business data processing. The HP 3000's high OLTP performance is achieved with tight integration of the operating system, the underlying PA-RISC hardware, and HP's database management systems ALLBASE/SQL and TurboIMAGE/XL. Performance is further streamlined by highly efficient I/O processing and maximum main memory utilization, which results in minimizing the number of physical I/Os that must actually be performed. Robust functionality A full range of OLTP functionality is offered on the HP 3000, including built-in capabilities to ensure superior data integrity, system security, easy systems management, and sophisticated performance measurement and analysis tools. The 900 Series offers significant functional extensions: a greatly extended address space for more data and application expandability, an enhanced command interpreter, integrated systems and network management, symmetric multiprocessing, support for the high-performance HP-FL fiber-optic disk interface, and optional configurations supporting very high data availability for mission-critical applications. Open systems and standards Open systems means the interoperability of different vendor systems and the support of standard application programming interfaces (APIs) that allow for easy portability of applications between the HP 3000 and systems from different vendors. The HP 3000 supports an open environment that provides a wide variety of de facto and industry standards: operating system, user interfaces, networking, databases, development tools, and programming languages. These standards include X/Open's POSIX operating system interface, MS Windows and OSF/Motif graphical user interfaces, distributed application services based on the International Standards Organization's (ISO) Open Systems Interconnect (OSI) model, ARPA Telnet, IBM's de facto standards SNA network and SAA application interoperability, ANSI standard SQL relational database management system, industry-leading multivendor application development tools, and ANSI standard programming languages. Systems management HP 3000 systems management encompasses a broad range of management functions and systems services that includes performance management, administration, system security, system availability, operations, and storage management. Systems management is an important aspect for the standalone system with limited networking, for a distributed node in a network, and for large data centers, which are the hubs of major and minor networks. HP's OpenView provides for the integration of systems and network management in distributed environments. Ease-of-use The HP 3000 offers a simple, consistent, and intuitive interface for end users and system administrators; major multivendor CASE tools for application development; and an online Help facility. With these features, the HP 3000 provides simpler system management and administration relative to traditional computers as well as traditional UNIX systems.
