A unique instance ID is created whenever a new instance of a SOA composite application is initiated either automatically by an external consumer of the application, or manually by an administrator from the Test Web Service page.
SOA composite application instance is first created when the composite is invoked. When the service components within the composite receive a subsequent invocation, a corresponding service component instance is created that refers to the composite instance ID previously created.
If you want to programatically find these instances, refer to :
9.3.2 Finding Instances
My concern is how these numbers for instance ID gets generated.
thanks for the Help..!!!
Instance Id's (CIKEY) are generated from ID_RANGE table, every call to this table returns a different range of sequences. Instance Ids will not collide across different Managed servers. Instance ID gets refreshed with each server restarts and is not equal across nodes or after restart.
Information to configure this range can be found in 12.2.9 InstanceKeyBlockSize in the Oracle BPEL Process Manager Performance Tuning Guide.
