Receiving Inbound Messages with MSMQ Receiver

With the Siebel application as the receiver (inbound messaging), you design a workflow that reads from the queue and converts the XML messages found there into Siebel message format. Then, the EAI Siebel Adapter updates the appropriate tables within the Siebel Database.

NOTE:  MSMQ Receiver must run on the same machine where you have defined the receiving queue.

There are two methods for receiving messages for a Siebel application:

• Receive and Execute Service (ReceiveDispatch)
• Receive, Execute, Send Response (ReceiveDispatchSend)

Receiving and Dispatching MSMQ Messages with MSMQ Receiver

The following procedure describes how to set up your system to receive an inbound message from MSMQ by MSMQ Receiver, then perform an action based on that message within the Siebel application.

To receive and dispatch messages using the EAI MSMQ Transport (MSMQ Receiver)

1. Access the Windows Computer Management tool by choosing the Start menu, Programs, Administrative Tools, and then Computer Management.
2. Set up a queue to send messages to the Siebel application.
   1. Name the queue an easily identified name, such as toSiebel.
   2. Create a message in the queue.

      NOTE:  To test this procedure adequately, you must have a partner application that can put a valid message for the Siebel application into the queue.

3. Create a named subsystem for the MSMQ Receiver using the following lines:

   create named subsystem MyMSMQSubsys for subsystem MSMQSubsys with MsmqQueueMachineName=SiebelServer1, MsmqPhysicalQueueName=fromSiebel, MsmqRespQueueMachineName=SiebelServer2, MsmqRespQueueName=toSiebel

   create named subsystem SiebelEcho for subsystem EAITransportDataHandlingSubsys with DispatchService="Workflow Process Manager", DispatchMethod=RunProcess, DispatchWorkflowProcess="MyMSMQWorkflow"

   start task for comp MSMQRcvr with ReceiverConnectionSubsystem=MyMSMQSubsys, ReceiverDataHandlingSubsystem=SiebelEcho, ReceiverMethodName=ReceiveDispatch

   NOTE:  The DispatchService and DispatchMethod parameters are optional.

4. In Siebel Tools, set up a workflow for receiving and dispatching a message from MSMQ as shown in the following figure:

   NOTE:  For details on the Business Process Designer, see Siebel Business Process Framework: Workflow Guide.

5. Create the following process properties:

   Name	Data Type	In/Out
   Test Message	Hierarchy	In/Out
   Test XML	Binary	In/Out
   Error Code	String	In/Out
   Error Message	String	In/Out
   Object Id	String	In/Out
   Siebel Operation Object Id	String	In/Out

6. Set up the first step of the workflow after Start to use the EAI XML Converter business service with the XMLDocToIntObjHier method to convert the XML message to a Siebel Message using the following input and output arguments:

   Input Argument	Type	Property Name	Property Data Type
   <Value>	Process Property	Test XML	Binary

   Property Name	Type	Output Argument
   Test Message	Output Argument	SiebelMessage

7. Set up the second step to use the EAI Siebel Adapter with the Upsert method to update the Siebel Database, using the following input arguments:

   Input Argument	Type	Property Name	Property Data Type
   SiebelMessage	Process Property	Test Message	Hierarchy

   NOTE:  In order to test this scenario adequately, you must have a partner application that can put a valid message for the Siebel application in the queue.

8. Save the workflow.

Receiving, Dispatching, and Sending MSMQ Messages with MSMQ Receiver

The following procedure shows you how to set up your system to receive an inbound message from MSMQ by MSMQ Receiver, perform an action within a Siebel application based on that message, and then send a synchronous response back to the external system.

To receive, dispatch, and send messages using the EAI MSMQ Transport (MSMQ Receiver)

1. Access the Windows Computer Management tool by choosing the Start menu, Programs, Administrative Tools, and then Computer Management.
2. Set up an MSMQ queue to receive messages from the Siebel application.

   Give the queue an easily identified name, such as fromSiebel.

3. Set up another queue to send messages to the Siebel application.
   1. Name the queue an easily identified name, such as toSiebel.
   2. Create a message in the queue.

      NOTE:  To test this procedure adequately, you must have a partner application that can put a valid message for the Siebel application into the queue.

4. Create a named subsystem for the MSMQ Receiver using the following lines:

   create named subsystem MyMSMQSubsys for subsystem MSMQSubsys with MsmqQueueMachineName=SiebelServer1, MsmqPhysicalQueueName=fromSiebel, MsmqRespQueueMachineName=SiebelServer2, MsmqRespQueueName=toSiebel

   create named subsystem SiebelEcho for subsystem EAITransportDataHandlingSubsys with DispatchService="Workflow Process Manager", DispatchMethod=RunProcess, DispatchWorkflowProcess="MyMSMQWorkflow"

   start task for comp MSMQRcvr with ReceiverConnectionSubsystem=MyMSMQSubsys, ReceiverDataHandlingSubsystem=SiebelEcho, ReceiverMethodName=ReceiveDispatchSend

   NOTE:  The DispatchService and DispatchMethod parameters are optional.

5. In Siebel Tools, set up a workflow for receiving and dispatching a message from MSMQ as shown in the following figure:

   NOTE:  For details on the Business Process Designer, see Siebel Business Process Framework: Workflow Guide.

6. Create the following process properties:

   Name	Data Type	In/Out	Value
   Test Message	Hierarchy	In/Out	Not applicable
   Test XML	Binary	In/Out	Test Message from Siebel Server
   Error Code	String	In/Out	Not applicable
   Error Message	String	In/Out	Not applicable
   Object Id	String	In/Out	Not applicable
   Siebel Operation Object Id	String	In/Out	Not applicable

7. Set up the first step of the workflow after Start to use the EAI XML Converter business service with the XMLDocToIntObjHier method to convert the XML message to a Siebel Message using the following input and output arguments:

   Input Argument	Type	Property Name	Property Data Type
   <Value>	Process Property	Test XML	Binary

   Property Name	Type	Output Argument
   Test Message	Output Argument	SiebelMessage

8. Set up the second step to use the EAI Siebel Adapter with the Upsert method to update the Siebel Database, using the following input arguments:

   Input Argument	Type	Property Name	Property Data Type
   SiebelMessage	Process Property	Test Message	Hierarchy

   NOTE:  To test this scenario adequately, you must have a partner application that can put a valid message for the Siebel application into the queue.

9. Save the workflow.

After running the workflow, confirm that the message is removed from the queue using the MSMQ Explorer. In this example, the Siebel Database is updated with the message in the fromSiebel queue. Also, a response message will be in the queue specified by the MSMQRespQueueName and MSMQRespQueueMachineName arguments.
