The maximum number of remote users per database server. The default is the Maximum Number of Users (-n) parameter value, divided by the Maximum Number of Servers (-Mn) parameter value.
Use Maximum Clients per Server (-Ma) to specify the maximum number of remote users per database server. The Maximum Clients per Server (-Ma), Minimum Clients per Server (-Mi), and Maximum Servers (-Mn) startup parameters apply only to databases that are accessed from remote network nodes.
In most cases, the default behavior is desirable. Note that the default calculation is usually high because it assumes that all users are remote users, while the number specified with -n includes local users. If servers become overloaded with clients, reset the -Mn parameter to increase the number of servers.
