## Conventions

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 choices. You can choose one or more items or no items. Do not type the brackets on the command line. However, you must include the brackets in the syntax for OpenVMS directory specifications and for a substring specification in an assignment statement.

## Chapter 1
Overview of This Manual

Together, the two parts of this manual explain tasks and concepts related to managing a Compaq OpenVMS 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:

- User-level tasks such as creating and editing files and command procedures. For more information, refer to the OpenVMS User's Manual.
- DIGITAL Command Language (DCL) commands. For more information, refer to the OpenVMS DCL Dictionary.

## 1.1 Using the OpenVMS System Manager's Manual

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

- This book, OpenVMS System Manager's Manual, Volume 1: Essentials
- A second book, OpenVMS System Manager's Manual, Volume 2: Tuning, Monitoring, and Complex Systems

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:

Concept | Section

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.

### 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:

- The client. This is Microsoft Windows based software that you install on a PC and use to perform management operations.
- The server. This software must be installed on all OpenVMS systems to be managed. You do not interact directly with the server, the client does that.

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:

- OpenVMS Alpha Version 7.3 Upgrade and Installation Manual
- OpenVMS VAX Version 7.3 Upgrade and Installation Manual
