7.1 5620 SAM database management overview
The 5620 SAM uses the following to store data such as network object information
and statistics data:
• 5620 SAM database
• auxiliary database
5620 SAM database
A 5620 SAM system requires a central database for persistent storage. The database
can be on the same station as a 5620 SAM main server, or on a separate station. A
redundant 5620 SAM deployment has two databases that are synchronized in a
primary-standby configuration to limit data loss in the event of a failure.
You can manage the following central database functions and parameters:
Database safeguards
In addition to the protection of system redundancy, the 5620 SAM has mechanisms
that raise alarms for the following:
• database disk and tablespace capacity issues
• redundancy events, misconfiguration, and failures
• database backup misconfiguration and failures
• archive log management actions and failures
• internal errors that may represent a security risk
• size constraint and ageout constraint policy violations
Auxiliary database
A 5620 SAM auxiliary database is a distributed database that is deployed as a cluster
of database members on separate stations. An auxiliary database cluster is a
load-balanced, highly fault-tolerant component that is maintained using in-service
backup, restore, and member recovery methods.
You can use a 5620 SAM GUI client to perform the following auxiliary database
cluster management functions:
• View the general auxiliary database cluster and cluster member status.
• View server performance statistics to monitor cluster performance.
• Create, schedule, or delete snapshots, which are cluster member data backups.
When a cluster member fails, you must return the cluster member to operation, or the
cluster performance may degrade. See section 15.6 for information.
• security
• statistics data retention
• data synchronization
• backups and restores
• historical record retention
• object ageout
• log storage
• error monitoring
• alarm handling
