18.2.5.1 Message Batching

The EMS batching process clubs messages into one single message before it is sent to BAM EMS. This feature enables the sender to send all messages in one batch over JMS. The batching process can improve network performance by limiting the number of round trips from the sender to JMS server to BAM EMS. 19 User Messaging Service Performance Tuning 19-1 19 User Messaging Service Performance Tuning This chapter describes tips for tuning the User Messaging Service. It contains the following sections: ■ Section 19.1, About Oracle User Messaging Services ■ Section 19.2, Basic Tuning Considerations ■ Section 19.3, Database Tuning for Optimal Throughput

19.1 About Oracle User Messaging Services

Oracle User Messaging Service enables users to receive notifications sent from SOA applications that are developed and deployed to the Oracle WebLogic Server using Oracle JDeveloper. At the application level, there is notification activity for a specific delivery channel such as SMS or E-Mail. For example, when you build a SOA application that sends e-mail notification, you drag and drop an Email Activity component from the JDeveloper Component Palette to the appropriate location within a workflow. The application connects then sends notifications. For more information on Oracle User Messaging Service, see Oracle WebLogic Communication Services Administrators Guide, Oracle WebLogic Communication Services Developers Guide, and the Oracle Fusion Middleware Developers Guide for Oracle SOA Suite.

19.2 Basic Tuning Considerations

Depending on your User Messaging usage and performance issues, you may consider tuning the following: ■ SMPP Driver Performance Tuning ■ Email Driver Polling Frequency

19.2.1 SMPP Driver Performance Tuning

Short Messaging Peer-Peer Protocol SMPP messaging drivers can be configured using Enterprise Manager. One of the key parameters for optimizing SMPP performance is WindowSize. This is especially important when the SMPP driver is connected to a remote SMSC and there is high network latency between the two elements. Configuring the WindowSize parameter enables the SMPP driver to send several requests to the Short Messaging Service Center SMSC before waiting for an
