All lines of an out-of-line multiple-line status display that
have not been presented occupy message buffers. Therefore, the operator
should erase these displays when they are no longer needed to free the message buffers.
During system initialization, the system does not use the MLIM
and RLIM parameter values in the CONSOLxx parmlib member until either
the system log or a console becomes active or processing by the nucleus
initialization program (NIP) completes. After NIP processing, consoles
other than the initialization console become active and buffer space
becomes important.
When activating an extended MCS console, specify the optional
alert percentage and an event control block (ECB) address on the MCSOPER
macro. Then, when the message data space reaches the specified percentage,
the system will post the ECB.
