Critical system problems, such as memory shortfalls or hardware errors on system disks, may affect the BS2000 components which are responsible for the input and output of console messages. In situations in which the normal output paths are blocked, the system selects an alternative output path for important messages, the so-called “emergency path”.
Outputs via the emergency path are known as an emergency messages or emergency queries. They are initially output directly at the system’s main console via internal service interfaces.
Formats
%E.text ?E.text | Emergency message Emergency query |
After this - if possible - the messages from the regular message processing functions are transferred. See the next section.
Irrespective of the logical console output or display by means of the SHOW-PENDING-MSG command, it is only possible to answer emergency queries at the physical console at which the message was output.
Response format
E.text | Response to emergency query |
