4.4.7. Transformation extra processings

Automatically retry transformation on error

This extra-processing allows defining criteria to automatically retry a transformation if an error occurs.

The parameters are :

Error message patterns  The patterns that will be tested against the error message.
Retry strategy 

Allows you to determine the time interval that needs to be used for the retries.

  • No retry 
    • No retry will be performed
  • Keep trying for 15 minutes
    • Will retries after 2, 4, 7, 10 and 15 minutes.
  • Keep trying for 1 hour 
    • Will retries after 2, 4, 8, 15, 30 and 60 minutes.
  • Keep trying for 3 hours 
    • Will do 6 retries in the first hour, then every hour.
  • Keep trying for 8 hours 
    • Will do 6 retries in the first hour, then every hour.
  • Keep trying for 1 day 
    • Will do 4 retries in the first hour, then every hour.
  • Keep trying for 3 days 
    • Will do 5 retries in the first 2 hours, then every 3 hours.
  • Keep trying for 5 days, once a day 
    • Will do One retry every day for 5 days at the same time as the first try.
  • Keep trying for 7 days 
    • Will do 5 retries in the first hour, then every 3 hours for 3 days, then every 6 hours.
  • Keep trying for 30 days 
    • Will do 5 retries in the first day, then once a day.
Email Recipients  Address to which an email will be sent if a retry is scheduled. You can add a comma-separated list of recipients or a metadata.
Email Subject   Email message subject. You can use metadata. 
Email body   Email message Body. You can use metadata. 
 
There is as well a version of this extra-processing called "Automatically retry on errors (Multiple)" that can be used if some errors must be sent to different email addresses. Only the first error message pattern that matches the error message will trigger an email.

Automatically close errors

This extra-processing allows defining criteria to automatically close errors.

The field "Error message patterns" is a regex pattern and/or patterns that will be tested against the error message.

If the error message matches at least one of the patterns, the status of the message will automatically be set to Error(closed), as shown below.

Error Message Patterns

Note: In Babelway, we're using the standard Java version of REGEX, and it's the same used all over the system.


 

Error message patterns  The patterns that will be tested against the error message. If the error message matches at least one of the patterns, the status of the message will automatically be set to Error(closed).
