Progress
Startup Command and Parameter
Reference
Maximum Clients Per Server (-Ma)
n
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 pertain only to versions of Progress 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.
NOTE: For SQL-92 database brokers, there is a limit of one client per server. The maximum value does not apply.If experience proves that a given number of remote clients overloads a server or exhausts the file descriptors on the system, set -Ma to limit clients per server below that level. A file descriptor is an object that UNIX uses to identify a particular file. The file descriptors might be exhausted because Progress uses them to identify sockets.
