n
The maximum number of remote users per database server. The default is the parameter value, divided by the MaximumServers (-Mn) parameter value.
The Maximum Clients Per Server (-Ma), MinimumClients per Server (-Mi), and MaximumServers (-Mn) startup parameters pertain only to versions of OpenEdge that use shared memory. In addition, these 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. If experience proves that a given number of remote clients overloads a server or exhausts the file descriptors on the system, set the Maximum Clients Per Server (-Ma) parameter to limit clients per server below that level. A file descriptor is an object UNIX uses to identify a particular file. The file descriptors might be exhausted because OpenEdge uses them to identify sockets.
