composite sensors:
Implementing composite sensors within a SOA solution provides the ability to define trackable fields on messages and enables you to find a specific composite instance by searching for a field or fields within a message.
-> Composite sensors provide a method for implementing traceable fields on messages. Composite sensors enable you to perform the following tasks:
Monitor incoming and outgoing messages.
Specify composite sensor details in the search utility of the Instances page of a SOA composite application in Oracle Enterprise Manager Fusion Middle-ware Control. This action enables you to locate a particular instance.
Publish JMS data computed from incoming and outgoing messages.
Track composite instances initiated through business event subscriptions.
-> It basically means marking a variable or data field to be traced at runtime. So at runtime you can see the values of this field or variable for a running instance, but also you can search for running instances (e.g. find the running instance of which the field ‘order id’ has value ‘AB12345’).
