Adapters are SCA components and An Adapters integrates existing IT assets like EIS ( Enterprise Information Systems) with Business Integration Applications without any significant programming. Adatpters provides Transactional support, Asynchronous communication, connection pooling and Security beyond Webservices.
Types of Websphere Adapters:
Adapters are of two types 1.Application Specific Adapters and 2.Technology Specific Adapters. Application Specific Adapters connect to existing packaged applications like SAP, PeopleSoft. Technology Specific Adapter provides connecivity through Technologies and Protocols like Flatfiles, JDBC, Email and FTP.
Advantages of Websphere Adapters:
*. It is based on Industry Standards and widely accepted by different vendors.
*.These are internally uses J2EE environment which is used for Connection pooling, End-to-End Java EE security Management and Distributed Transactions.
Adapters supports multithread and supports Tow kinds of Event Delivery. They are Ordered and UnOrdered Event Delivery.
Ordered Event Delivery is a Single Thread Delivers one event at a time.here events polled in which they were created.
UnOrdered Event Delivery is a Multi Thread Delivers event at a time.here events polled in which they were created.
API's are used by Adapters to Expose service and Exchange Data b/w Services :
EMD ( Enterprise Metadata Discovery) : Is used to Expose Servies and Business Objects to other Applications.
DESPI ( Data Exchange Service Procider Interface ) : Is used to Exchange Data between Adapter Components and IBM Process Server Runtime.
Event Polling for Inbound Adapters :
Database trigger or script creates an event in the Event Table. then The adapter polls the event in Event table for New Item. then the corresponding data will be retrived and placess into the queue to start the process. once the data is processed then adapter removes that event from the event table and placess into Archive. Then from that Archive table these events will be deleted by some manual scripts.
