Oracle BPEL Process Manager supports sending the attachment stream to multiple receivers. For Oracle BPEL Process Manager to send a stream to multiple receivers, it must read the attachment stream from the database using the readBinaryFromFile XPath function and pass the stream to the appropriate targets.

With the default configuration, Oracle Mediator can pass an attachment stream to only one target receiver, which can be another component or a web service/adapter. The second target cannot receive the attachment. When you define the persistStreamAttachment property for the Oracle Mediator component, Oracle Mediator can pass an attachment stream to multiple target receivers.

Oracle Mediator requires the persistStreamAttachment property for streaming attachments where the source message that contains the attachment is shared by multiple target receivers. Set this property to true in composite.xml to enable the streaming of attachments to multiple targets. The following example provides details.

component name="Mediator1">
   <implementation.mediator src="Mediator1.mplan"/>
   <property name="persistStreamAttachment">true</property>
</component>
