PRODUCT NAME:

SPD 14.70.22

RSX-11M-PLUS, Version 4.6

DESCRIPTION

RSX-11 M-PlUS is a product of Mentec Inc., and is
licensed under Compaq Computer Corporation's Standard Terms and Conditions.
RSX-11 M-PlUS is a disk-based, multi-user operating
system that provides a multi-programming environment
and real-time capabilities using a priority structured,
event-driven scheduler. It is a superset of the RSX-11 M
Operating System designed to maximize performance of
large memory and general purpose PDP-11 processors.
Time-shared, Real-time

Time-shared program development and interactive processing, real-time tasks, and batch streams can execute concurrently. The system's software priority levels
enable the user to compile or assemble, debug, install
and execute tasks, and run batch streams without significantly affecting real-time response.
Priority Levels

The system recognizes 250 software priority levels. The
user-specified task priority determines the task's eligibility to execute. A task can be fixed in a partition to ensure
immediate execution when activated, or it can reside on
a disk while it is dormant making memory available to
other tasks. Task checkpointing allows tasks to be displaced from memory to enable higher priority, nonresident tasks to execute.

automatic memory compaction minimizes memory fragmentation within a partition.
Multi-User Features

A multi-user program development facility is provided.
Multi-user features include lOGIN/lOGOUT with passwords, device and file access protection, a round-robin
scheduler (running under the real-time executive), and
concurrent execution of equal priority tasks via executive level swapping provide a time-sharing environment.
The system keeps passwords in an encrypted form, using a one-way encryption algorithm. Additional password and access control features can be enables by a
system manager.
The system keeps passwords in an encrypted form, using a one-way encryption algorithm. Additional password and access control features can be enabled by a
system manager.
In addition, accounting information is logged to a disk
file. This information includes, among other things, per
user connect time, CPU time, and pages printed.
Command Line Interpreters

RSX-11 M-PlUS supports the traditional MCR command interface, the easy-to-use Digital Command language (DCl), and user-written command interpreters.

Memory

User-written Tasks

Memory sizes from 512K bytes to 4,088K bytes are
supported. Memory is logically divided into partitions
in which tasks are loaded and executed. The system
controls the placement of tasks within a partition and

Tasks can be written in the supplied MACRO-11 assembly language or in optionally available languages,
such as FORTRAN-77, BASIC-PlUS-2, and PDP-11
C. User libraries and shareable libraries are supported.

RSX-11 M-PLUS, Version 4.6

SPD 14.70.22

Tasks can be written so the system automatically loads
a single, re-entrant code section of a multi-user task and
an impure section for each invocation of the task.

Batch Processor

A powerful, multi-stream BATCH facility is provided with
RSX-11 M-PLUS indirect command file processing capabilities. The batch commands are in DCL or MCR
format, making this capability easy to use. Status is returned to the batch processor as each step is completed,
allowing for conditionalized branching. The batch processor collects all print files from a batch stream and
spools them along with the log file. The queue manager gives the system manager control over the multiple
batch streams and print queues.

Mapping and Instruction and Data Space

On Micro/PDP-11/53, Micro/PDP-11/53 PLUS,
Micro/PDP-11/73, Micro/PDP-11/83, Micro/PDP-11/93,
PDP-11/44, PDP-11170, PDP-11/84 and PDP-11/94
systems, supervisor mode mapping can be used to map
libraries, thus increasing the effective size of a user task.
On these systems, hardware mapping facilities are
available to user tasks to separate instructions and data
into separate 64K byte address spaces, doubling the
address space available to tasks.

Features

Note: Not all of the available languages support the
Instruction and Data Space and Supervisor Mode available on these systems. Check the Software Product
Description (SPD) for the specific language in question.

•

Overlapped disk seek for RA60/70/71 172/80/81/82,
RA90/92,
RK06/07,
RM02/03/05/06/80,
and RP04/05/06 disks.

•

Request queue optimization which reduces average
seek times on disks.

•

Disk Data Caching which for many applications significantly reduces actual disk I/O operations, thereby
increasing system performance.

•

Dynamic dual pathing support for RK06/07,
(RP04/05/06,) and RM02/03/05/06/80 disks.

•

Support for the RQZX1 SCSI adapter on Micro
/PDP-11/53+, Micro/PDP-11/93, and upgraded 11
/73 and 11/83 systems.

•

Support for a specific set of Digital SCSI devices
(RX33, RZ23L, RZ24L, RZ26L, and RZ29B disks,
and TZ30 tape device) using the RQZX1 SCSI
adapter.

•

Support for virtual devices

•

Software addressing of up to 256 terminals.

•

Support for Terminal Servers on Ethernet using the Local Area Transport (LAT) protocol.
DECnet-11M-PLUS software is needed for this feature.

Utilities

An extensive set of utilities is provided to facilitate file
and system maintenance, error analysis, and program
debugging. Two editors are provided, EDT and RSX
EDI.
File Structures and Facilities

The file system provides file structures for block structured devices. It also provides automatic space allocation, multi-user file protection, device independence,
and logical device assignment.
Files are logically grouped into directories which can be
labeled by a name. or by a pair of numbers, conventionally denoting a user and a group to which the user
belongs.
Two file access facilities are available: File Control Services (FCS) and Record Management Services
(RMS-11).
RMS-11
supports three file organizations, Sequential, Relative,
and Multi-keyed Index Sequential (ISAM), and provides
sequential and direct access modes.

• Terminal Services Architecture (TSA) - Terminals on
an RSX-11 M-PLUS system with DECnet can function as remote command terminals on other RSX
or OpenVMS systems in the network that also has
TSA capability. Likewise, terminals on those remote
systems can function as command terminals on the
RSX-11 M-PLUS system.

FCS supports sequential and direct access to sequentially and randomly organized files.
The use of the File Control Services increases the task
size by approximately 2K to 8K bytes, depending on the
number of open files and services desired. The Record
Management System (RMS) requires at least 8K bytes
per task.

•

Support for the Digital Multinational Character Set
and for user-written translation routines for other
character sets.

•

Upward compatibility for most nonprivileged tasks
with RSX-11M-PLUS, Version 2.0, RSX-11M, Version 4.0, and Micro'RSX, Version 1.0. Task rebuilding
is usually not required.

SPD 14.70.22

RSX-11 M-PLUS, Version 4.6

PDP-11/94 processors supporting separated Instruction and Data space (1- and D-space), a pregenerated
system is provided that utilizes these features. A
non-I- and D-space system which does not support
Supervisor mode is provided for the Micro/PDP-11
/23, the PDP-11/23-PLUS, and the PDP-11/24. An
automated procedure deletes one of the pregenerated systems, if it is not required, in order to recover
some disk space.

• As of Version 3.0 of RSX-11 M-PLUS and Micro'RSX,
the Executive has been vectored. Users can vector their privileged tasks which, in most cases, allows the tasks to be run on subsequent versions
of RSX-11 M-PLUS or Micro'RSX without rebuilding
them.
• Ability to connect to, and transfer files to and from,
another system over a serial asynchronous communications link. The file transfer and data terminal emulation utilities allow easy file interchange between
the RSX-11M-PLUS system and another PDP-11
running a RSX Operating System, or an OpenVMS
system running VAX-11 RSX. Communication between any of these systems is established through a
terminal line. The file transfer utility uses the protocol
DDCMP, which provides error detection and correction to assure data integrity. As MFT transfers files
using RMS block I/O, all types of data files can be
copied.

SOURCE CODE INFORMATION

Source code for the RSX-11 M-PLUS Executive and
most privileged code modules is provided in the binary
kit options on 1600 BPI Magtape and TK50 cartridge
tape. This source code is included in order to generate
the RSX-11 M-PLUS system.

Shadowed Disk Support - Allows one of two disks
of the same type to be designated as a shadowed
backup of the other disk mounted as a Files-11 volume. All writes to disk are written automatically to
both shadow members. Reading and writing are performed, optionally, on a load sharing basis. In the
event of a read failure on the primary drive, the system automatically reads the data from the secondary
drive.

A separate source license is required for the
RSX-11 M-PLUS utilities and non privileged modules. A
kit for these sources is available on 1600 BPI Magtape,
and TK50 Cartridge Tape.

Powerfail/Restart - Allows the system to continue
executing upon power restoration, restarting all interrupted I/O activities and notifying any active task
through a powerfail asynchronous system trap entry
point.

This source code is provided on an "AS IS" basis without warranty of any kind either express or implied.
HARDWARE RESTRICTIONS
