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
