The following table displays all possible configurations of the WRITE_LOCK
parameter.
Table 4-6. Possible configuration of the WRITE_LOCK parameter.
4.12.2 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.
