Range of values
5 or the number of dispatchers configured, whichever is greater
MAX_DISPATCHERS specifies the maximum number of dispatcher processes allowed to be running simultaneously. The default value applies only if dispatchers have been configured for the system.
The value of MAX_DISPATCHERS should at least equal the maximum number of concurrent sessions divided by the number of connections for each dispatcher. For most systems, a value of 250 connections for each dispatcher provides good performance.
