5 XLA and TimesTen Event Management

The TimesTen Transaction Log API (XLA), supported by TimesTen Classic, is a set of C language functions that enable you to implement applications.

You can perform the following:

• Monitor TimesTen for changes to specified tables in a local database.

• Receive real-time notification of these changes.

The primary purpose of XLA is as a high-performance, asynchronous alternative to triggers.

Note:

In the unlikely event that TimesTen replication solutions described in Overview of TimesTen Replication in the Oracle TimesTen In-Memory Database Replication Guide do not meet your needs, it is possible to use XLA functions to build a custom data replication solution.

This chapter includes the following topics:

• Overview of TimesTen XLA

• Writing an XLA Event-Handler Application

• Using XLA as a Replication Mechanism

• Other XLA Features

See XLA Reference.
