Table 5-16. Write_Lock Parameter
5.13.2 MAX_NOTIFY
The MAX_NOTIFY parameter value is the maximum number of alert reports that the resource can have
sent without getting a confirmation, corresponding to the amount of buffer space available for alert
messages. The number can be set lower, to control alert flooding, by adjusting the LIM_NOTIFY
parameter value. If LIM_NOTIFY is set to zero, then no alerts are reported.
