Description: Indicates the number of bytes of data processed by the processing subsystem. If neither of the cSourceSubsystem or cProcessingSubsystem items are in the associated JOB-INFO-STAGE object, then this object contains the size of this job, in bytes. The last OID field for this dynamic object contains the job ID. Additional information: This count may be incremented by values other than one as blocks of data are processed; blocks of data (which may be as large as 2K bytes) will be processed in a varying amount of time. During the processing of a job and even when a job completes, an exact count of the number of I/O bytes processed by the job is not necessarily to be expected.
