Summary of OpenVMS Version 7.3 New Features
Table 1–1 (Cont.) Summary of OpenVMS VAX and OpenVMS Alpha Version 7.3 Software
Features
Programming Features
Large Page-File sections (Alpha) Previous limits for page-file sections have been extended significantly to
take advantage of larger physical memory. Now images that use 64-bit
addressing can map and access an amount of dynamic virtual memory
that is larger than the amount of physical memory available on the
system.
Multipath system services New services have been added that allow you to return path
information and enable, disable, and switch specific I/O paths to any
device.
Multiprocess debugging (Alpha) Debugger support for multiprocess programs has been extensively
overhauled. Problems have been corrected and the user-interface has
been improved.
Nonpaged executive (Alpha) In previous releases, some of the OpenVMS Alpha executive code
was nonpageable (it resided permanently in memory) and some was
pageable. As of OpenVMS Alpha Version 7.3, the base operating system
images contain nonpageable code only.
This new nonpageable design improves the performance of system
services from 5 to 20 percent and uses almost no extra memory because
of the method used to link the images.
Performance API The Performance Application Programming Interface (API) provides a
documented functional interface—the $GETRMI system service—that
allows performance software engineers to access a predefined list of
performance data items.
