Is it possible to handle errors in a batch job?
Handling errors inside a batch job can be complicated considering the huge amount of data this scope is designed to take. When processing 1 million records, it’s almost impossible to log everything.
What happens when an adapter fails in a batch?
This means that the failure of one operation in a batch should not affect any other operation in any way. However, batches are atomic, so the failure of one message results in an error for the batch, and no operations are processed.
What happens when a batch processor has a fatal error?
If the Batch Processor has encountered a fatal error, it is likely there will be cases that were not processed. Once the cause of the fatal error has been identified and resolved, the Batch Processor can be run again to reprocess all cases, including those missed previously due to the fatal error.
What happens when a batch job fails in mule?
When processing a batch job instance, a processor inside a batch step may fail or raise an error. When this occurs – perhaps because of corrupted or incomplete record data – Mule logs the stack traces following this logic: Mule gets the exception’s full stack trace. Mule strips that stack trace from any messages.
What happens when batch service encounters an error?
If the Batch service encounters an error when starting a task on a node, it marks the task as completed. The error information is returned within a failureInfo element in the response body of List the files associated with a task and Get information about a task APIs.
How to check if command was successful in batch?
This likely doesn’t work with start, as that starts a new window, but to answer your question: If it does not return a error level but does give output, you can catch it in a variable and determine by the output, example (note the tokens and delims are just examples and would likely fail with any special characters)
When to return NULL in a batch job?
If the record hasn’t failed in any step, then it returns null. Returns the Exception for the last step in which the current record has failed. If the record hasn’t failed in any step, then it returns null. Imagine a batch job that polls files containing contact information.
