fails. Note, however, that if the primary manager system fails, the second
manager system will not be able to take over as the primary manager
system.
•
If the Sun PU2.1 SNA Server running in multiple physical sites, define one
manager system for each physical site. This allows local Domain Name
System (DNS) requests for resources and minimizes the delay in transferring
information from the server to the manager systems.
•
Sun recommends that you do not define more than three manager systems,
since adding extra manager systems increases the traffic.
Note –
When the Sun PU2.1 SNA Server software is installed, no manager
systems are defined.
