BATCH_JOB_EXECUTION

BATCH_JOB_EXECUTION_CONTEXT

The BATCH_JOB_EXECUTION_CONTEXT table holds all information relevant to an Job's ExecutionContext. There is exactly one Job ExecutionContext per JobExecution, and it contains all of the job-level data that is needed for a particular job execution. This data typically represents the state that must be retrieved after a failure so that a JobInstance can 'start from where it left off'.

CREATE TABLE BATCH_JOB_EXECUTION_CONTEXT  (
  JOB_EXECUTION_ID BIGINT PRIMARY KEY,
  SHORT_CONTEXT VARCHAR(2500) NOT NULL,
  SERIALIZED_CONTEXT CLOB,
  constraint JOB_EXEC_CTX_FK foreign key (JOB_EXECUTION_ID)
  references BATCH_JOB_EXECUTION(JOB_EXECUTION_ID)
) ;

Below are descriptions for each column:

JOB_EXECUTION_ID: Foreign key representing the JobExecution to which the context belongs. There may be more than one row associated to a given execution.
SHORT_CONTEXT: A string version of the SERIALIZED_CONTEXT.
SERIALIZED_CONTEXT: The entire context, serialized.
