System Administrator Guide
Server activity switches
The standby server initiates an automatic server activity switch when it cannot
communicate with the primary server. A 5620 SAM administrator performs a
manual server activity switch, which is typically a planned server maintenance or test
operation. For security reasons, you cannot use a 5620 SAM GUI or OSS client to
perform a server activity switch.
Figure 7-4 shows the server and database roles before an activity switch.
Figure 7-4 Server and database roles before server activity switch
During a server activity switch, a main server does not process SNMP traps, attempt
to synchronize NEs, or collect statistics. Auxiliary servers process outstanding
requests during an activity switch, but do not communicate with a main server.
The following occurs during a server activity switch:
• The primary server raises alarms about the event.
• Each GUI client receives notification of the activity switch and displays a
message about the server unavailability during the activity switch.
Figure 7-5 shows the server and database roles after a successful activity switch.
