SBR performs audit functions on all SBR database tables to verify the validities and staleness of the database records and remove those invalid or stale records from the databases.
The frequency of audit functions is configured in the
Audit Operation Rate field on the GUI page. The SBR database audit function runs continuously through all SBR database tables until it is suspended automatically due to the local SBR MP congestion. Audit suspension can occur for several reasons:
- Congestion of the SBR server running in the audit
- Binding audit will not send audit messages to session SBRs that are in congestion
- Binding audit is suspended if session integrity messaging reaches an engineering configurable level
The
Audit Operation Rate applies to all SBR Database audits, regardless of the database type.
Each active SBR server runs the audit independently:
- Each table is audited no more than once per ten minute period
- Each active SBR generates an audit statistics report for each table it audits whenever a pass of that table is completed
At the end of each audit cycle, the SBR audit function generates a report with all the audit statistics.
