6.1 Error handling procedure

To handle errors during system operation:

  1. Check if a message has been issued.
    In the event of an error, one or more error messages should have been output to the console or message log.
  2. Check the error event and take appropriate action.
    Check error messages that have been output. Correct the cause of the error according to the error handling procedures described in the manual uCosminexus Stream Data Platform - Application Framework Messages. For details about how to handle major problems, see 6.4 How to handle major problems.
    If the error cannot be resolved, contact the customer engineer (i.e., contact Hitachi customer service according to the contract you entered into at the time you purchased the product).
  3. Collect the data needed for handling the error
    Collect the data needed to determine the cause of the error by referencing 6.2 Data to be collected in the event of an error.
