MPE/iX Information Management
Commercial applications primarily use database applications. The 900
Series provides ALLBASE/SQL, which includes TurboIMAGE/XL, a network
database management product, and HP SQL, which has a relational interface
to data. ALLBASE/SQL provides a TurboIMAGE/XL cross-development
environment. The relational interface, HP SQL, is fully compatible with
the version of SQL in most common use. It provides relational access for
increased flexibility.
ALLBASE/SQL and other tools form Hewlett-Packard's information management
framework. These include:
* Programming languages and tools.
* Reporting and presentation tools that allow access to information
without programming.
* A common data dictionary that provides the integration necessary
to tie the system together.
The products that meet these needs on the 900 Series are:
* System Dictionary/XL, which provides programmers and system
administrators with a single source for documenting all aspects of
the system, from data definitions to configuration information.
This central source of information aids in developing and
maintaining applications and effectively managing system
resources. The System Dictionary/XL has programmatic interfaces
for easy integration with other software. You can customize
System Dictionary/XL to meet your needs.
* Optimizing compilers, which use HP Precision Architecture (HP-PA)
to allow all programming on the 900 Series computers to be done in
high-level languages. The compilers are integrated with MPE/iX to
provide convenient access to ALLBASE/SQL and other information
managements subsystems.
* VPLUS/V, which is a forms design and screen-handling tool for
programmers.
* Toolset/XL, which includes facilities for full screen editing,
symbolic source-level debugging, and version management of source
code. It provides a high-productivity, integrated environment for
application development.
* Transact/XL, which is a procedural, high-level programming
language for transaction processing applications. It provides the
functions of a high-level language, such as COBOL, combined with a
comprehensive set of powerful verbs that can perform several
functions in a single call.
Self-adjusting System Tables
Most system tables in MPE/iX are self-adjusting. MPE/iX continuously
monitors and adjusts tables to fit the workload. Usually, the system
manager can do this without shutting down the system.
On-line Diagnostics for Peripherals
Hewlett-Packard Customer Engineers (CEs) are equipped with on-line
diagnostic tools for many HP peripheral devices. A CE can remotely run
diagnostics without shutting down the system.
Disc Failure Tolerance
MPE/iX allows any system disc not critical to the functioning of the
operating system to go off-line without affecting the system. Users
cannot access files on off-line discs.
Automatic Power Fail Recovery
MPE/iX and the 900 Series hardware provide automatic power fail recovery.
When a power failure starts, the system initiates a power failure
procedure to preserve the operating environment before the complete loss
of power. A battery pack ensures the validity of main memory for a
minimum of 15 minutes. If power is restored within 15 minutes, the
system automatically resumes processing from the point at which the power
failure occurred, and jobs continue from the point of interrupt.
