Specifications

OpenVMS Operating System for Alpha and VAX (Versions 7.1, 7.1–1H1, 7.1–1H2, and 7.1–2) SPD 41.87.06
Debugger
The OpenVMS Debugger allows users to trace program
execution, as well as display and modify register con-
tents using the same symbols that are present in the
source code.
The debugger contains a Heap Analyzer feature that
allows you to graphically view memory allocations and
deallocations in real time.
Alpha System-Code Debugger
The OpenVMS Alpha System-Code Debugger is a ker-
nel code debugger. It allows a system code developer to
trace the execution of nonpageable system code at any
Interrupt Priority Level (IPL). Based on the OpenVMS
Alpha Debugger, the system-code debugger uses the
same interface and most of the same command set.
System Dump Analyzer (SDA) Utility
In the event of a system failure, OpenVMS writes the
contents of memory to a preallocated dump file. This
dump file can later be analyzed using SDA. System
dumps can either be full memory dumps, where all
memory is written, or selective memory dumps, where
only memory in use at the time of the system failure
is written. Full memory dumps require a dump file big
enough to hold all memory. Selective memory dumps
write as much of the memory in use at the time of the
system failure that will fit into the dump file. Therefore,
this file is often much smaller in size. The dump file
can be located on any locally connected disk. Dump
compression allows both full and selective dumps to be
written to smaller files than required for uncompressed
dumps.
RMS File Utilities
RMS file utilities allow users to analyze the internal
structure of an RMS file and to determine the most ap-
propriate set of parameters for the file. The RMS file
utilities can also be used to create, load, and reclaim
space in an RMS file. Refer to the Operating System
Environment section of this SPD for more information
on RMS.
File Differences Utility
This utility compares the contents of two files and lists
those records that do not match.
Translated Image Environment (TIE) (Alpha Only)
OpenVMS Alpha provides an array of services that
allow the operation of programs which have under-
gone binary translation from OpenVMS VAX images.
These programs perform virtually all user-mode func-
tions on OpenVMS Alpha and operate in combination
with other programs (images) that have been translated
from OpenVMS VAX or have been built using native
compilers on OpenVMS Alpha. Without requiring spe-
cial source code, the TIE resolves differences between
the VAX and Alpha architectures, including floating-
point registers, condition codes, exception handling, and
ASTs.
The TIE included with OpenVMS Alpha can run images
that have been translated elsewhere. The DECmigrate
for OpenVMS Alpha layered product can be used to
translate user-mode images from OpenVMS VAX. For
additional information on the characteristics of programs
suitable for binary translation, refer to the DECmigrate
for OpenVMS AXP Systems Software Product Descrip-
tion (SPD 39.44.xx)).
SYSTEM MANAGEMENT ENVIRONMENT
OpenVMS provides a variety of features that aid the sys-
tem manager in configuring and maintaining an optimal
system. The following features are available to system
managers.
OpenVMS Management Station Version 2.1
The OpenVMS Management Station is a Windows PC-
based tool that allows management of one or more
OpenVMS Cluster systems from a single point of con-
trol. For user account management, the Management
Station supports account creation, modification, and
deletion, as well as renaming accounts and displaying
account attributes. The OpenVMS Management Station
makes it possible to easily modify many accounts in a
single operation. It provides a comprehensive interface
to the user account management features.
Version 2.1 adds functionality for printer and queue
management. System managers can now manage all
the printers, print queues, and jobs in their environ-
ment via a centralized Windows GUI. This includes per-
forming such tasks as monitoring one or more print-
ers, adding and removing printers and their associated
queues, examining and modifying queue and printer at-
tributes, and requeuing or deleting jobs. In addition,
printer configuration information can be stored in a per-
manent database to ensure that the printer configuration
is recreated easily and accurately at reboot.
With this release, the system manager can perform
OpenVMS user account and printer management from
any MS-Windows based client (including Windows NT
and Windows 95), using a single set of Windows 95
