3. Click and hold the right mouse button (MB3), select Delete from the

number of client connections, the Sun PU2.1 SNA Server blocks further
connections until the number of connections drops below the new number
of licenses.
The Sun PU2.1 SNA Server allows you to create multiple instances of the Sun
Gateway Manager (SunGMAN) to protect against system failure. Each instance
of the SunGMAN is referred to as a manager system.
The following sections describe how to determine the number of manager
systems to define, how to add manager systems to the manager network, and
how to recover when 50% or fewer of the manager systems are available.
Each Sun PU2.1 SNA Server configuration requires at least one manager
system. When deciding how many additional manager systems to create, keep
the following in mind:
•
In a large network, Sun recommends that you define at least three manager
systems. If you define two manager systems, the 50% quorum rule requires
that both manager systems are running at all times.
•
If you have only two manager systems, set one of them to be the preferred
primary manager system. The primary manager system will continue to
operate as a primary manager system even if the second manager system
