Using OpenVMS System Management Utilities and Tools
2.1 Understanding OpenVMS System Management Tools
2.1.4.2 Using Compaq-Supplied Command Procedures for System Management
Compaq provides several command procedures for managing a system. Table 2–1
lists some commonly used command procedures.
Table 2–1 System Management Command Procedures
Command Procedure Function
SYS$SYSTEM:STARTUP.COM The system uses this command procedure to
automatically perform certain tasks that are required
to start up an OpenVMS system. This procedure is
executed when the system boots. Do not modify this
command procedure.
SYS$STARTUP:SYSTARTUP_VMS.COM STARTUP.COM executes this procedure when the
system boots. Add commands to this procedure to
perform site-specific tasks each time the system boots.
SYS$SYSTEM:SHUTDOWN.COM Use to shut down the system in an orderly fashion.
SYS$UPDATE:AUTOGEN.COM Use to automatically set system parameters and page,
swap, and dump file sizes to values appropriate for the
system configuration and work load.
SYS$UPDATE:VMSINSTAL.COM Use to install software on a running system.
2.1.5 System Management Utilities
With the operating system, Compaq supplies a number of system management
utilities to help perform system management tasks. A system management
utility is a program that performs a set of related operations. For example, the
Mount utility (MOUNT) makes disks and tapes available to the system, and the
Backup utility (BACKUP) saves and restores files.
Most system management utilities require special privileges. Generally, you run
these utilities from the SYSTEM account, which has all privileges by default.
Section 2.2 describes logging in to the SYSTEM account.
You invoke some utilities using the following command format:
RUN SYS$SYSTEM:utility_name
To invoke other utilities, such as MOUNT and ANALYZE/DISK_STRUCTURE,
enter a DCL command. For example:
$ ANALYZE/DISK_STRUCTURE
Table 2–2 lists the system management utilities and their purposes. This manual
describes how to use most of these utilities. For detailed information about utility
commands and qualifiers, refer to the OpenVMS System Management Utilities
Reference Manual.
