Issue/Introduction

Secondary console is not communicating with the mainframe.
Not all messages are appearing on an z/OS console session. Commands can be issued but not all responses received.
 
 

Cause

The master console of this LPAR was full. A display of the consoles showed a very high NBUF value:
 
 
D C                                                                 
CNZ4100I 12.30.13 CONSOLE DISPLAY 014

Environment

Release : 11.5 and 11.6

Component : CA Automation Point

Resolution

After a command was issued to make the master console roll the messages, the buffer was relieved and the AP console started to receive messages again.
