What is the NFM-P main database?

Description

This section describes the NFM-P main database, and how to manage the associated data integrity and security functions.

An NFM-P main database stores classic mediation network data that includes object configurations, device backups, and statistics: The NFM-P uses the data to create a network model for use by NFM-P management functions.

An NFM-P system requires a central database for persistent storage. The database can be on the same station as the main server, or on a separate station. A redundant NFM-P deployment has two identical main database instances in a synchronized primary/standby configuration to limit data loss in the event of a failure.

You can manage the following database functions and parameters:

security statistics data retention data synchronization backups and restores historical record retention

object ageout log storage error monitoring alarm handling

Main database safeguards

In addition to the protection of system redundancy, the NFM-P 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
