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:
To show all the options for setting up the terminal type:
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:
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:
So that you can see all the users logged in the cluster you can type these commands:
To list the information of the user, type:
To show system memory resources of the cluster just type:
SHOW MEMORY /PHYSICAL
To display all the active licenses of the cluster, type:
To run the IRC client if there is a client available (Deathrow Cluster has) type:
To phone other, users type:
To answer a phone if someone is calling you, just type:
To use the Cluster Mail Client type:
To change your password type:
To determine your allowed disk space or storage in the cluster so that you will not be banned, type:
To read the notes posted by some users go to the Directory of Notebook class MAIN by typing:
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.
