Article Title: The Oracle Rdb Run-Time Code Generator for the OpenVMS Itanium Platform -
» HTML,
» PDF
Article Abstract: For more than 20 years, the Oracle Rdb database engine
has created subroutines of executable code generated at run time. Native
executable code streams for VAX and Alpha architectures are generated. When
moving to the Itanium architecture, an instruction emulation environment was
initially employed to speed development and product introduction. This emulation
environment has been transitioned to generation of native Itanium instruction
streams. This paper discusses the environment and development of the run-time
executable code generation within the Oracle Rdb database engine on Itanium
OpenVMS systems.

Article Title: OpenVMS Power Management -
» HTML,
» PDF
Article Abstract: Power utilization of data centers is becoming a
critical factor, often making a crucial impact to the total cost of ownership.
It also can make a serious impact on the environment of our increasingly
resource conscious world. In this context, this article focuses on the Power
Management facilities provided by HP OpenVMS for Integrity servers Version 8.4.
While Power Management features are not new to OpenVMS, the strategies employed
by various versions differ. This article elucidates these and helps the
administrator make a decision as to when and how to use each power setting.

AlphaServer systems. More recently, he designed and wrote Software Interrupt
Services (SWIS), code to do low level interruption and change-mode handling,
software interrupts, and AST initiation for VMS on the Itanium Processor Family.
Burns is a co-inventor on 3 patents relating to OpenVMS work and holds a
Master's degree in Electrical Engineering from the University of Rochester, NY.
Prithvi Srihari is a Software Engineer in the OpenVMS Kernel Development Team.

Article Title: OpenVMS – Paged Dynamic
Memory Fragmentation
Causing Performance Problems- » HTML, » PDF
Article Abstract: This Knowledge Brief (KB) discusses the Open VMS
performance problems that occur when Paged Dynamic Memory (PAGEDYN) becomes
excessively fragmented. PAGEDYN is a general purpose area of memory maintained
by VMS for storing data structures such as shared logical names, ACP Caches,
resident image headers, known file entries, and structures for RMS file sharing.
This KB also discusses how PAGEDYN fragmentation can be detected, how the
PAGEDYN fragmentation can affect performance, and how the performance problems
can be eliminated.
Author Bio: John Hockett started programming on Digital Equipment
Computers on the RT-11 Operating system in 1974 and had the opportunity to manage
the first VAX installed in the State of Idaho that anchored a real time
satellite data collection system for the Department of Interior. John joined
Digital Equipment in 1985 and is currently a Consultant IV with the VMS Global
Competency Center, an NRSS for HP high-profile customers, and an Escalation
Specialist. John is often utilized by HP sales to provide VMS technical
assistance in closing sales and supporting customer migrations. John holds a BS
in Computer Science from Colorado State University and lives with his wife and
family in Grand Junction, Colorado.

Article Title: SYSMON for OpenVMS Systems -
» HTML,
» PDF
Article Abstract:
One of the challenges that the customers face with the legacy OpenVMS
environments is to have their legacy VMS boxes running mission critical
applications monitored real time and the incidents are fixed as soon as they are
detected. The challenges here are to have their existing monitoring systems
integrated with the up-to-date solutions and to have the monitoring systems
deployed at the first place when there is no monitoring system already in place.
We have developed a DCL based monitoring solution (SYSMON) targeted to be
deployed on the legacy VMS environments. This has already been successfully
deployed and running on the systems of 3 customer accounts.

Article Title: Virtual Alpha Systems:
Quality Control and Testing - » HTML,
» PDF
Article Abstract:
Virtual Alpha systems are software abstraction layers that turn a modern,
industry-standard server into the equivalent of an Alpha hardware system. Such
systems must present to the unmodified OpenVMS or TRU64 operating system an
environment that is identical in functionality to the original hardware. A good
virtual system allows the use of a completely unmodified OS, including its
drivers, all customer applications, and the original PCI controllers.
Quality control and testing of such virtual systems require extensive test
procedures, comparable to those used to develop the original hardware. The test
phases and the quality assurance process had to be established for these new
technologies, and they are described in this article.
