Correlation Management enables the tracking of long-running transactions across multiple channels or servers. These transactions are correlated as standalone transactions or as part of a correlation set for batch processing. Transactions are correlated using the user-defined correlation ID as single message processing can produce multiple sub-transactions with different Transactions IDs that need to be correlated together.
Set Correlation plays an important role during batch processing, where each transaction is correlated to a specific batch correlation set. The transaction correlation state can be updated at any point of the process. This allows transactions to be processed by multiple channels, where each channel can update the transaction state of a single transaction providing a unified view through the entire processing cycle.
Transaction overall state is denoted as open or closed, indicating the final transaction state. Transaction Details provide the transaction correlation history from the initial Open state to various Functional, Business, or Customized transaction updates. This is a key feature enabling the user to track the transaction through all correlation steps and identify actions performed by any given channel on a transaction.
The Correlation Management tab in iWay Business Activity Monitor enables the user to see the overall state of the transaction. It provides important information, such as Correlation ID, which is used throughout the transaction life cycle, as well as the overall state of the transaction and the Last Event which occurred for the given transaction.
The user can view additional information for the transaction by accessing TX Details (Transaction Details) which provides a detailed view into the transaction history. For example, the following image shows the correlation set being open for the batch transaction followed by linking of the four child transactions.
When looking at a singular transaction from the correlation management view, the user can see various updates to the transaction state. For example, the following image shows the transaction in the Open state since the routing country cannot be found for the transaction.
The user can drill down even further to investigate the error by clicking the associated transaction ID to see the details. The error is marked with a red flag, indicating in the transaction history where the country for the transaction cannot be set, as shown in the following image.
