8 — 5620 SAM system redundancy
8-8 Alcatel-Lucent 5620 Service Aware Manager
5620 SAM
System Administrator Guide
The following occurs after a successful database switchover:
• The primary server connects to the new primary database.
• Archive logging begins on the new primary database.
• The primary server directs each auxiliary server to use the new primary database.
When a database switchover fails, the primary and standby database roles do not
change. No automatic database realignment occurs as a result of a switchover.
Database failovers
The 5620 SAM database failover function is enabled by default. A failover occurs
when a main server cannot communicate with the primary database, but can
communicate with the standby database and the managed NEs. When this happens,
the main server directs the standby database to become the primary database.
A database failover occurs only if the following conditions are true.
• The standby database is configured, operational, and reachable.
• The main server can communicate with the managed NEs.
Figure 8-8 shows the server and database roles before a failover.
Figure 8-8 Server and database roles before database failover
Figure 8-9 shows the server and database roles after a successful failover.
