OpenVMS

Simple Tips and Commands for OpenVMS

I decided to blog about some commands for OpenVMS clusters which might come in handy for some n00bz and starters like me. (Trust me, I’m still an OpenVMS n00b).

In this tutorial  I will be showing DCL (Digital Command Line) commands so that you would be able to work in with some of the clusters that offer free access:

DEC

Terminal Setup

To show all the options for setting up the terminal type:

SHOW TERMINAL

Note: In the OpenVMS, you can just type two or three letters (it actually depends because there are commands that have the same first two letters) for each DCL because the OpenVMS easily identifies a shortcut command to their full DCL. Thus, instead of typing ‘show terminal’, you can type ‘sh ter’.

With all the options shown in the cluster, I recommend you use a VT100 emulation especially if you are using a terminal emulator like puTTy.

SET TERMINAL /INQUIRE /VT100

Navigation and Information Gathering Commands

To list all the directories type:

DIR

To move to a certain directory you can just type SET DEFAULT [.DIR]. For example I want to move to the WEB directory, I can just type in:

SET DEFAULT [.WEB]

To go back to the main directory just type the command:

SET DEFAULT SYS$LOGIN

To edit the contents of a certain file just type:

EDIT FILE.HTML

So that you can see all the users logged in the cluster you can type these commands:

SHOW USERS

OpenVMS users

FINGER

finger command in OpenVMS

To list the information of the user, type:

FINGER USERNAME

To show system memory resources of the cluster just type:

SHOW MEMORY

SHOW MEMORY /PHYSICAL

To display all the active licenses of the cluster, type:

SHOW LICENSE

To run the IRC client if there is a client available (Deathrow Cluster has) type:

IRC

To phone other, users type:

PHONE USERNAME

OpenVMS Phone Facility

To answer a phone if someone is calling you,  just type:

PHONE ANSWER

To use the Cluster Mail Client type:

MAIL

To change your  password type:

SET PASSWORD

To determine your allowed disk space or storage in the cluster so that you will not be banned, type:

SHOW QUOTA

To read the notes posted by some users go to the Directory of Notebook class MAIN by typing:

NOTES

Start DECWindows Session

It’s just easy to start a DECWindows session, click this link in order to have a DECWindows session and have the x11 forwarding enabled.

Exiting the Cluster

For OpenVMS starters, always remember to log off or log out your session rather than closing your terminal so that the admin of the cluster will not have a hard time killing unnecessary processes in the machine.

Commands:

LOGOFF

LOGOUT
