This figure includes a rectangle on the left labeled "Oracle WebLogic Server" at the top. The "Oracle WebLogic Server" rectangle includes a rectangle inside it labeled "SOA Infrastructure JEE app" at the top. Inside the "SOA Infrastructure JEE app" rectangle is another rectangle labeled "BPEL Engine" at the top. Inside the "BPEL Engine" rectangle are three rectangles organized vertically. The labels for these three rectangles, starting from the top rectangle, are:
Dispatcher Processing
Process Persistence
Audit/Metrics
The space between the Dispatcher Processing rectangle and the Process Persistence rectangle is labeled "In-memory queue."
To the right of and outside of the WebLogic Server rectangle are five other rectangles organized vertically.
Here are the key points about these five other rectangles, starting from the top rectangle:
The top rectangle is labeled "JMS Messages." An arrow starting from this rectangle points to the "SOA Infrastructure JEE app"rectangle label.
The next rectangle is labeled "HTTP Messages." An arrow starting from this rectangle points to the "SOA Infrastructure JEE app" rectangle.
The next rectangle is labeled "DB Messages." An arrow starting from this rectangle points to the "SOA Infrastructure JEE app" rectangle.
The next rectangle is labeled "SOA Db (jdbc/SOADataSource)." An arrow starting from the "SOA Infrastructure JEE app" rectangle points to this rectangle.
The bottom rectangle is labeled "SOA MDS (jdbc/mds/MDS_LocalTxDataSource)." An arrow starting from this rectangle points to the "SOA Infrastructure JEE app" rectangle.
