Hewlett-Packard Co. officials are marking the 30th anniversary of the OpenVMS operating system’s introduction by telling users of the software that it still doesn’t have an expiration date.

To deliver that message, HP has brought out some of its top executives, including Martin Fink, senior vice president and general manager of the company’s business-critical systems group. During a webcast on Friday, Fink responded to questions submitted by members of the Chicago-based Encompass user group. Encompass, which originated as a group for customers of the former Digital Equipment Corp., also posted a document containing written responses to questions that were posed to Fink in advance of the webcast (PDF format).

In addition, Mark Hurd, HP’s chairman, CEO and president, has recorded a video that can be viewed on an OpenVMS 30th anniversary Web site that the vendor has set up. In the video, Hurd tells OpenVMS users that the operating system remains a “key product” and that HP “will continue to support it for the foreseeable future.”

Moreover, HP last week announced an updated version of the operating system that is due out within the next two weeks and will include new hardware support plus other features. The company also said it plans to add support for the JBoss and MySQL open-source technologies in a subsequent release next year.

OpenVMS was released on Oct. 25, 1977, and initially known simply as VMS. The software was developed by DEC, which later was acquired by Compaq Computer Corp., which in turn was purchased by HP in 2002.

The acquisitions made the OpenVMS user community nervous — as did HP’s subsequent decision to end development and sales of its AlphaServer systems, the hardware line that was synonymous with OpenVMS. HP says AlphaServer users should switch to its Itanium-based Integrity servers.

But some users are worried that pulling the plug on the AlphaServers will send a signal to independent software vendors that OpenVMS is just a second cousin to HP-UX, the company’s version of Unix, and thereby influence future porting decisions on key applications.
