Row chaining is a bottleneck that causes disruption in database performance. We should avoid row chaining as much possible. In this blog, we'll discuss row chaining, how to identify it, and how to remove or avoid it completely.
Every time an Oracle ® Database reads or writes data to a disk, the database generates disk input and output (I/O) operations. The performance of many software applications is limited by disk I/O, and applications that spend the majority of central processing unit (CPU) time waiting for I/O activity to complete are I/O bound. I/O calibration helps to address this issue.
