      Describe Exception Handling in Compsite Applications<\/h2><\/span>\n

      * Fault handlers define how the BPEL process service component responds when web services return data other than what is normally expected<\/p>\n

      Describe the Fault Management Framework<\/h2><\/span>\n

      * See
      \n–       Using Fault Handling in a BPEL Process<\/a>
      \n– See       this post<\/a> for SOA 10g fault management framework.
      \n– See       this post<\/a> for SOA 11g fault management framework.
      \n– See       this post<\/a> for a SOA 11g fault policy tutorial.<\/p>\n

      Describe Compensation handling within a BPEL process<\/h2><\/span>\n

      See Using Compensation After Undoing a Series of Operations<\/a><\/p>\n

      Compensate Activity<\/h3><\/span>\n

      * Used by BPEL process service component to undo previously completed transactions<\/strong>.
      \n* Can only be used:
      \n– In a fault handler<\/strong> of the scope to be compensated.
      \n– In the compensation handler<\/strong> of the scope to be compensated.
      \n* If a scope being compensated by name was nested in a loop, all branches are compensated in reverse order.
      \n* If compensation handler is not defined, then defaults to reverse order of the completion of those scopes.<\/p>\n

      CompensateScope Activity<\/h3><\/span>\n

      * BPEL 2.0 only.
      \n* Used to start compensation on a specified inner scope that has already completed successfully.
      \n* Can only be used from
      \n– within a fault handler,
      \n– another compensation handler,
      \n– or a termination handler.
      \n* When you create a compensateScope activity, you select a target that must refer to the immediately-enclosed scope.
      \n– The scope must include a fault handler or compensation handler.<\/p>\n

      Describe Correlation concepts<\/h2><\/span>\n

      * See
      \n–       Using Correlation Sets in an Asynchronous Service<\/a>
      \n* Correlation sets enable you to correlate asynchronous messages based on message body contents.
      \n* You define correlation sets when interactions are not simple invoke-receive activities.
      \n* Correlation sets provide another method (like WS-Addressing) for directing web service responses to the correct BPEL process instance.
      \n– Used to identify asynchronous messages to ensure that asynchronous callbacks locate the appropriate client.
      \n– Provide correlation of asynchronous messages based on message body contents.
      \n– Used for services that do not support WS-Addressing or certain sophisticated conversation patterns (e.g. A > B > C >A instead of A > B > A).<\/p>\n

      Manage Transactions with SDO<\/h2><\/span>\n

      Hmmm. can’t find this topic.<\/p>\n
