8 Event Notification

Event notification is done through the Transaction Log API (XLA), which provides functions to detect changes to the database.

XLA monitors log records. A log record describes an insert, update, or delete on a row in a table. XLA can be used with materialized views to focus the scope of notification on changes made to specific rows across multiple tables.

TimesTen also use SNMP traps to send asynchronous alerts of events.

• Detect Transaction Modifications With the Transaction Log API

• Monitor Tables With Materialized Views and XLA

• Monitor Problems With SNMP Traps
