Tools and utilities

Use the following tools to perform Database Module fault monitoring tasks:

•Oracle Enterprise Manager (OEM) Console: Used by the database administrator for backup and recovery and database fault management.

For details, see “Security and Administration” on page 69.

•System Management Console: Launches the OEM Console and Oracle Monitoring Application. Provides log and alarm information. For details, see MCP System Management Console Basics.

•Oracle Monitoring Application: Gathers operational status of the database and sends alarms and operational measurements (OMs) to the System Management Console. The tool uses Oracle SNMP agents to gather information about disk and tablespace utilization, and other information.

For details, see “The Oracle Monitor component” on page 41.

Database failover

In the unlikely event of a failure of the primary database, application queries are redirected to, that is, “failover” to the secondary database.

During a failover only registration data can be written to the secondary database and application components periodically attempt to access the primary database. Once the primary database returns to service, all data processing reverts to the primary database.

All applications access and update data via request/response transactions. If the primary database does not respond to a request, the initiator of the request does the following:

•Raises an alarm indicating a problem with the database

•Switches over to the secondary database and reinitiates the request

ATTENTION

A minor alarm is raised when applications are connected to the primary database and the connection to the secondary database fails.

For information about database backup and recovery, resynchronization, replication, and optimization, see “Security and Administration” on page 69.
