EAI Queue for Error Handling

The EAI Queue provides temporary storage for data in transit between Siebel Business applications and external applications and a means by which to monitor the data exchange. This temporary storage of data can facilitate error recovery in the event that the flow of data to or from Siebel is interrupted. Error Handling mechanism can be configured to push and pop messages from the EAI Queue based on an OOB Business Service “EAI XML Queuing Service”.Each entry in the EAI Queue may contain the following information:
■ XML file containing the data object in transit
■ Processing status of data object
■ Reference ID for data object in external application
■ Additional fields to be used for error information and other external application specific
A business service API is also provided to the EAI Queue. This business service contains methods to update information held in the queue and allows other components in the Siebel application, as well as customers, to develop software to use the queue. The business service contains the following methods:
■ AddMessage. Adds an XML data object to the queue.
■ GetMessage. Retrieves an XML data object from the queue.
■ GetStatus. Retrieves processing status of the data object.
■ UpdateStatus. Updates the processing status of the data object.
■ DeleteMessage. Removes an XML data object from the queue.

Steps to Configure an EAI Queue:
1. Navigate to Sitemap –> Integration Administration Screen –> EAI Queue
2. Create a New Record
3. Fill in the name of the EAI Queue e.g., “TEST EAI Retry Queue” without the quotes.

Steps to use / send Error Messages onto EAI Queue:
1. Call OOB “EAI XML Queueing Service” from the Error Handling workflow process to post the error message onto EAI Queue using “AddMessage” method.
2. Pass on the Error XML to the Error Handling workflow which in turn would post it onto the EAI Queue.
3. Error Message logged into the EAI Queue are listed as shown below:

Advantages of this Approach:
1. This uses OOB Siebel functionality without extra license to incorporate Error Handling.
2. Number of Custom Objects required to build for Error Handling decreases, thereby increasing performance, reducing development time, easier to debug.
