    • Method Detail

      • setShortContextLength

        public void setShortContextLength​(int shortContextLength)
        The maximum size that an execution context can have and still be stored completely in short form in the column SHORT_CONTEXT. Anything longer than this will overflow into large-object storage, and the first part only will be retained in the short form for readability. Default value is 2500. Clients using multi-bytes charsets on the database server may need to reduce this value to as little as half the value of the column size.
        Parameters:
        shortContextLength - int max length of the short context.

      • updateExecutionContext

        public void updateExecutionContext​(JobExecution jobExecution)
        Description copied from interface: ExecutionContextDao
        Persist the updates of execution context associated with the given jobExecution. Persistent entry should already exist for this context.
        Specified by:
        updateExecutionContext in interface ExecutionContextDao
        Parameters:
        jobExecution - JobExecution instance that contains the context.

      • saveExecutionContexts

        public void saveExecutionContexts​(java.util.Collection<StepExecution> stepExecutions)
        Description copied from interface: ExecutionContextDao
        Persist the execution context associated with each stepExecution in a given collection, persistent entry for the context should not exist yet.
        Specified by:
        saveExecutionContexts in interface ExecutionContextDao
        Parameters:
        stepExecutions - a collection of StepExecutions that contain the contexts.
