Using the z/OS console screen

Most people are familiar with using SDSF from an ISPF screen to manage z/OS, and not from the operator console.  Ive been running z/OS under my laptop using zPDT, and Ive had to brush up my operating skills because I could not get the system up to be able to use ISPF and SDSF!

If you have problems and cannot get ISPF started you will need to use the operator console.
Use the MVS control command see here

Hints for using the z/OS console.

If you issue a command to z/OS (for example D A,L) you get a display like

To clear scrollable messages in the top box use the K command. Action messages will remain.
To clear (and remove) the lower box, use the K E,D command.

To remove the action messages from the top box use K E,1,1 This deletes the top message.
If you get too many action messages, you will not see the scrollable messages, and so you will need to clear some of the action messages.
You can use the “K S,REF” command to configure how the console is configured, and what messages automatically scroll off the screen.
