Setting the Payload Threshold

2-24 Oracle Fusion Middleware Users Guide for Technology Adapters

2.17 Streaming Large Payload

Oracle JCA Adapters support large payload processing for both inbound and outbound processing. However, only the following adapters support the streaming feature explicitly: ■ Oracle File Adapter For more information, see Section 4.5.4, Oracle File Adapter Scalable DOM . ■ Oracle AQ Adapter For more information, see Section 7.2.11, Stream Payload Support . ■ Oracle JMS Adapter For more information, see Supports Streaming Large Payload on page 8-5. ■ Oracle Database Adapter For more information, see Section 9.3.5, Streaming Large Payload . The other adapters do not have explicit support for both.

2.18 Batching and Debatching Support

The batching and debatching functionality is supported for these adapters: ■ Oracle JCA Adapter for Files ■ Oracle JCA Adapter for FTP ■ Oracle JCA Adapter for Databases Oracle JCA Adapter for File and Oracle JCA Adapter for FTP consist of a Reader to debatch a single large file into several batches. You need to specify the batch size during the design-time configuration. In addition, the adapter includes a Writer to batch a set of messages into a single file. For more information, see Section 4.2.4, File Debatching . Oracle JCA Adapter for Databases consists of a Publish component to poll a set of tables to detect events. This component can raise events to the BPEL process one record at a time or multiple records at a time. For more information, see Section 9.4.2.2, Polling Strategies .

2.19 Adding an Adapter Connection Factory

The logical deployment of adapters implies the creation of ConnectionFactory objects in the weblogic-ra.xml deployment descriptor file. The weblogic-ra.xml file contains run-time connection parameters for an adapter. To add the connection information and assign to a JNDI name, you must edit the corresponding weblogic-ra.xml file of the resource adapter by either using Oracle WebLogic Server Administration Console or WLST scripts. For more information about creating a connection factory, see Oracle Fusion Middleware Installation Guide for Oracle WebLogic Server. The following steps describe how to set up a Database connection factory in the Oracle WebLogic Server Administration Console. This section includes the following topics: ■ Section 2.19.1, Creating a Data Source
