Welcome

Mom Software Services specializes in design, development and test of software applications for production automation systems, data aquisition systems, equipment control systems, communication control systems and database information systems running on the OpenVMS operating system.

Since 1987 Mom Software Services has developed many software applications. Some of them had the requirement to run 24*365 without interruption. This requires a great knowlegde and experience of designing applications for the OpenVMS operating system.

The core business of Mom Software Services is:

• Design, implement and test any application on OpenVMS VAX and OpenVMS Alpha
• Make your applications Year 2000 compliant
• Let your applications make optimal use of the OpenVMS resources and mechanisms
• Tune your OpenVMS systems
• Take your existing applications in maintenance for updates, modifications or bug fixes
• Advice you about OpenVMS systems in general or about designing applications on the OpenVMS operating system
• Development of our own utilities (eg. VIP - VMS Information Provider) and sell it over the Internet

We have the knowledge and expertise to make your project a complete success. We take both fixed-price orders as subsequent calculation orders.

Why OpenVMS ?

OpenVMS is the most well designed computer operating system in the world. It is very popular in environments where stability, reliability, high performance, disaster tolerance, security, scalebility and clustering are required.

Here are some facts:

• Multi-user interactive user support, full shared-resources clustering, uptime, robust file system with individual volume limits circa one terabyte (and thousands of volumes), huge system performance and application scaling, networked GUI interface, 64-bit flat virtual addressing, built-in tools for local backup and recovery, far better "DLL-like" support for modular coding and distributions, built-in record management support (heirarchical database), rolling upgrades of layered products and the operating system in cluster environments (continuous uptime, even with software upgrades), built-in batch-print capabilities, support for a variety of networking protocols (COM, SMB, NFS, IP, DECnet, X.25, http, etc), remote network system logins, built-in system dump and analysis facilities, built-in multi-user security and auditing, built-in multiple and mixed-language programming capabilities, good documentation, orderable CD-ROM source listings of the operating system internals and source code, process and engineering that targets the avoidance of introducing security problems and typical virus infection paths, built-in system tuning tools, built-in application debugging and application dump tools, support for symmetric multiprocessing environments of up to 32 CPUs in a single system (and up to 96+ nodes in a cluster), built-in standard product installation tools and associated product installation packaging tools, a central goal of upward-compatibility of user-mode applications and tools over OpenVMS releases, support for systems with 256 gigabytes of physical memory, available full operating system and hardware support from a single source, powerfull and easy to use no-nonsense user interface, etc.
• Continuous OpenVMS system uptimes of over ten years are not unheard of. Some of these systems -- those configured in clusters -- can be running current OpenVMS releases, with very long cluster uptimes, with the rolling-upgrade capabilities.
• OpenVMS has more than 450,000 installed systems with over 10 million users.
• OpenVMS is the #1 rated operating system in the healthcare industry.
• More than 90% of the world's CPU chips are manufactured on lines running OpenVMS.
• More than 50% of the world's cellular phone billing systems run OpenVMS.
• More than 95% of the world's top financial exchanges run on OpenVMS or Tandem systems.

For these reasons OpenVMS is used in many production environments and financial and medical institutions where non-interruptability and continuous computing (24*365) are an important issue. Military contractors also accept it as the one and only operating system for providing maximum security with maximum numerical throughput.

Still today many other operating systems have tried to come up to its level, but none of them come even close to the many qualities and advantages of OpenVMS.

The OpenVMS WebRing

OpenVMS has many loyal users who appreciate it's features. There are many OpenVMS-related web sites that provide a lot of helpful information. By building a large WebRing of OpenVMS sites, we can make these web sites easier to find.
