Passing Data to Future Steps (and recovering from a failed step) job, difference, beginning, following, database

amy

Regarding the BATCH_STEP_EXECUTION_CONTEXT table,

What this the difference between the SHORT_CONTEXT field and the SERIALIZED_CONTEXT field?

I have a job with 2 steps. In both steps I am using the following at the beginning of the reader step after the database read:
       ExecutionContext exCtx = stepExecution.getExecutionContext();       exCtx.put(quot;somekeyquot;, someRecordsList);

Reason I ask is that for one step in this job, both these fields are populated and for another step I see that only the SHORT_CONTEXT field is populated after the job completes.

The code for this is identical in both steps and taken right from the book.
The stepExecution is taken from the @BeforeStep method.
Both steps are configured with an ExecutionContextPromotionListener and all the data from both steps appears in the BATCH_JOB_EXECUTION_CONTEXT table.

Might it something to do with the size of the Map?

Thanks,
TonyThanks in advance,
