Control Interval is analogous to a physical block for QSAM
files. It is the unit of I/O. Must be between 512 bytes to
32 k. Usually either 2K or 4K. A larger control interval
increases performance for sequential processing while the
reverse is true for random access. Under CICS when a record
is locked, the entire CI gets locked.
Control Area is a group of control intervals. CA is used
during allocation. CA size is calculated based on the
allocation type (cyl, tracks or records) and can be max of 1
cylinder |
