What Difference Exists Between Control Area And Control Interval? |
|
Answer» A Control Area is a set of Control Intervals and it works during ALLOCATION. The size of the Control Area depends on the type of allocation (cyl, tracks, RECORDS) and ots MAXIMUM reaches 1 cylinder. The Control Interval is something like a block for QSAM files, its size is ranged between 512 bytes and 32 kilobytes, NORMALLY 2 or 4 kilobytes. If the Control Interval is bigger the performance will also increase when it comes to sequential PROCESSING. A Control Area is a set of Control Intervals and it works during allocation.
