Designing XAI Receivers

Receivers define small pieces of code that wait for requests to be received through various sources. Each receiver references an XAI class where the small piece of code is defined. The following receiver classes are provided:

• STGRCVR The receiver that references this class polls the XAI upload staging table for new inbound requests.
• STGCTLRCVR: The receiver that references this class polls the XAI staging control table for new upload processes.
• DWNSTGRCVR : The receiver that references this class polls the notification download staging table (NDS) for new messages. (Not available in all products).
• OUTMSGRCVR : The receiver that references this class polls the outbound message table for new messages.
• JMSRCVR: Receivers that reference this class receive requests through a message queue that supports the JMS Queue interface, such as IBM MQSeries.
• TPCRCVR: Receivers that reference this class receive requests through a publish/subscribe model, such as TIBCO, or any system supporting the JMS Topic interface.
• FILESCANRCVR: Receivers that reference this class poll a given directory for files with a given file name pattern.
• XMLFILERCVR: Receivers that reference this class poll a given directory for XML files with a given file name pattern.

Multiple receivers may be defined for these receiver classes. For example, the XML file receiver defines the scan directory. If you have multiple directories that contain files to be uploaded, define a receiver for each directory.

All types of receivers reference an XAI Class and XAI Executer. If you require a new XAI Class or Executer because you use a protocol that is not currently supported, it is recommended that your implementers contact customer support.
