  • 1.  Retry mechanism in ACE v11 with file nodes

    Posted Tue February 09, 2021 07:45 AM
    Hi,

    In the ACE v11 file input node we have a tab for enabling the retry in case of failure with retry threshold and short retry interval.

    I have tested the behavior and it works fine, however, each message is treated as a separate transaction. So there is no way to know which one is the original message vs which one is the retry message. I don't see any headers which indicate this retry count.

    During processing, is there a way to identify what is the retry count so that the original message vs the retry messages can be linked with a uniqueue Transaction id?

    Appreciate help from the experts here.

    Regards,
    Saha

    Hi, 

    As I see, There is no property to identify message is original message or retry message. One e of the alternative solution is using "CURRENT_TIMESTAMP" . First timestamp value is original message and later timestamps can be considered as retried messages.

    Hello!

    You can do two things, either using transactionID or setting a retryCount. Like this

    Using retryCount
    -- Check if RetryCount property exists
    DECLARE retryCount INTEGER COALESCE(InputLocalEnvironment.Destination.File.RetryCount, 0);

     
    -- Increment RetryCount
    SET retryCount = retryCount + 1;

     
    -- Store the updated RetryCount in LocalEnvironment
    SET OutputLocalEnvironment.Destination.File.RetryCount = retryCount;

    OR

    Setting transactionID

    -- Generate a unique transaction ID 
    DECLARE transactionID CHARACTER;
    SET transactionID = UUIDASCHAR;

     
    -- Add the transaction ID to the message as a property
    SET OutputRoot.Properties.TransactionID = transactionID;
