Running with the z/OS System Console Deactivated

In deactivated mode, the z/OS System Console (CI) does not allow you to issue regular operator commands. Unsolicited z/OS messages are not displayed, with exception of z/OS priority messages. In addition you can:

• Send a message to the System Console from TSO or another z/OS® consoles (MCS/SMCS/EMCS), using the system console’s z/OS console name as destination,
• Respond to pending system requests (reply numbers). Care must be taken when doing this because no response messages are displayed. In deactivated mode you can also not issue a z/OS D R command to determine the pending requests.
