FTP, JMS, web services, databases, and so on). Oracle SOA Suite 11g creates
and maintains connections to these various technology adapters that may be re-
quested by an executing process instance.
With the growing need for business process optimization, efficient integration
with existing backend applications will eventually determine the success of your
SOA applications as well as your infrastructure. Imagine the stress that your in-
frastructure needs to handle when there are hundreds of composite applications,
and each in turn interacts with multiple technology and resource adapters in its
processing logic.
Adapters can be used in a composite application either as a Service (acting as
an entry point to the composite) or as a Reference (dealing with outbound invoc-
ations) and define Activation Specifications for Inbound Actions (Service) and
Interaction Specifications for Outbound Actions (Reference). You, as an Oracle
SOA Suite 11g administrator, can breathe easy as each of these adapter con-
nections can be individually managed and tuned at runtime from Oracle Enter-
prise Manager Fusion Middleware Control. The key properties that you should
aim to tune are payload/message size, concurrency, transactions, threads,
timeouts, batching, and streaming. It is essential to know how these adapter
properties can be tuned to achieve optimal performance and what effect one has
on the other. You can tune the adapters as described here:
