In this manual, any reference to OpenVMS is synonymous with Compaq OpenVMS.

VMScluster systems are now referred to as OpenVMS Cluster systems. Unless otherwise specified, references to OpenVMS Clusters or clusters in this document are synonymous with VMSclusters.

In this manual, every use of DECwindows and DECwindows Motif refers to DECwindows Motif for OpenVMS software.

The following conventions are also used in this manual:
Ctrl/ x A sequence such as Ctrl/ x indicates that you must hold down the key labeled Ctrl while you press another key or a pointing device button.
PF1 x A sequence such as PF1 x indicates that you must first press and release the key labeled PF1 and then press and release another key or a pointing device button.
[Return] In examples, a key name enclosed in a box indicates that you press a key on the keyboard. (In text, a key name is not enclosed in a box.)

In the HTML version of this document, this convention appears as brackets, rather than a box.

... A horizontal ellipsis in examples indicates one of the following possibilities:
  • Additional optional arguments in a statement have been omitted.
  • The preceding item or items can be repeated one or more times.
  • Additional parameters, values, or other information can be entered.
A vertical ellipsis indicates the omission of items from a code example or command format; the items are omitted because they are not important to the topic being discussed.
( ) In command format descriptions, parentheses indicate that you must enclose the options in parentheses if you choose more than one.
[ ] In command format descriptions, brackets indicate optional elements. You can choose one, none, or all of the options. (Brackets are not optional, however, in the syntax of a directory name in an OpenVMS file specification or in the syntax of a substring specification in an assignment statement.)
[|] In command format descriptions, vertical bars separating items inside brackets indicate that you must choose one, none, or more than one of the options.
{ } In command format descriptions, braces indicate a required choice of options; you must choose one of the options listed.
text style This text style represents the introduction of a new term or the name of an argument, an attribute, or a reason.

In the HTML version of this Conventions table, this convention appears as italic text.

italic text Italic text indicates important information, complete titles of manuals, or variables. Variables include information that varies in system output (Internal error number), in command lines (/PRODUCER= name), and in command parameters in text (where dd represents the predefined code for the device type).
UPPERCASE TEXT Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.
Monospace type Monospace type indicates code examples and interactive screen displays.

In the C programming language, monospace type identifies the following elements: keywords, the names of independently compiled external functions and files, syntax summaries, and references to variables or identifiers introduced in an example.

- A hyphen at the end of a command format description, command line, or code line indicates that the command or statement continues on the following line.
numbers All numbers in text are assumed to be decimal unless otherwise noted. Nondecimal radixes---binary, octal, or hexadecimal---are explicitly indicated.

Chapter 1
Overview of This Manual

Together, the two parts of this manual explain tasks and concepts related to managing a system. This chapter describes this manual and how to use it.

The OpenVMS System Manager's Manual explains system management tasks for new and experienced system managers. However, before performing these tasks, you should be familiar with the following items:

Information Provided in This Chapter

This chapter describes the following tasks:
Task Section
Using the OpenVMS System Manager's Manual Section 1.1
Finding information about managing complex environments Section 1.3
Finding information about managing small systems Section 1.4

1.1 Using the OpenVMS System Manager's Manual

The OpenVMS System Manager's Manual is made up of two parts:

Use these two books to get step-by-step instructions for general system management tasks.

The first page of each chapter in these books provides two tables to help you find information within the chapter.

The Task Table

The first table lists the major tasks described in the chapter. If you need to perform a task quickly, go directly to the section that explains that task. For example, in this chapter the task table lists the following tasks:
Task Section
Using the OpenVMS System Manager's Manual Section 1.1
Finding information about managing complex environments Section 1.3
Finding information about managing small systems Section 1.4

The Concept Table

The second table lists the major concepts explained in the chapter. If you want to learn more about an underlying concept, go to the appropriate concept section. For example, the concept table in this chapter lists the following concept:

How this manual relates to other system management documentation Section 1.2

1.2 How This Manual Relates to Other System Management Documentation

This manual is intended to be used as a companion to other OpenVMS system management manuals. The Preface of this manual lists the books you should be prepared to use along with the OpenVMS System Manager's Manual.

1.3 Finding Information About Managing Complex Environments

If you are managing large or complex configurations, you will need additional specialized information. Table 1-1 lists some typical environments and OpenVMS manuals containing specialized information for managing those environments.

1.4 Finding Information About Managing Small Systems

If you are managing a small standalone system---for example, a desktop workstation---you probably need to perform only basic system management tasks.

Table 1-2 lists the tasks you are likely to perform, and where to find instructions for performing these tasks.

Using OpenVMS System Management Utilities and Tools

This chapter provides general information about system management utilities and tools that are provided with the OpenVMS operating system.

Procedures for using utilities and tools to perform specific tasks are provided in the respective chapters that describe those tasks. For example, this chapter contains a general description of the System Management utility (SYSMAN). Section 8.11.2 describes how to use SYSMAN to manage disk quotas. Section 14.7 describes how to use SYSMAN to manage system parameters.

To use system management tools, you can also refer to the following documentation:

2.1.1 OpenVMS Management Station

The OpenVMS Management Station is a powerful, Microsoft Windows based management tool for system managers and others who perform account management tasks on OpenVMS systems. OpenVMS Management Station software provides a comprehensive user interface to OpenVMS account management across multiple systems. You can manage multiple systems from a single source.

OpenVMS Management Station software coexists with all of the existing OpenVMS system management utilities. Figure 2-1 shows a sample OpenVMS Management Station screen.

Figure 2-1 Sample OpenVMS Management Station Screen

OpenVMS Management Station addresses the problem of having to use multiple utilities to manage accounts. For example, creating an account usually involves the following steps:

  1. Add a UAF entry
  2. Grant rights identifiers
  3. Create a directory
  4. Create disk quotas
  5. Grant network proxies

These steps require that you use DCL, the Authorize utility, and the DISKQUOTA component of the SYSMAN utility. OpenVMS Management Station provides an easy-to-use interface to this process.

The OpenVMS Management Station consists of two components:

Documentation for the OpenVMS Management Station

The Microsoft Windows help files completely describe features, functions, instructions, and examples of using the OpenVMS Management Station. The OpenVMS Management Station Overview and Release Notes document provides an overview of OpenVMS Management Station and describes how to get started using the software.

Information about installing the OpenVMS Management Station on your Alpha or VAX computer and your PC is located in the following manuals:
