Startup Command and Parameter Reference

Maximum Clients Per Server (-Ma)

Operating system and syntax	UNIX Windows	-Ma n
Use with	Maximum value	Minimum value	Single-user default	Multi-user default
Database Server	2048	1	–	5 users/server

n

The maximum number of remote users per database server. The default is the Number of Users (-n) parameter value, divided by the Maximum Servers (-Mn) parameter value.

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.

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 Progress uses them to identify sockets.
