This manual covers the basics for understanding and investigating performance questions in Adaptive Server. It guides you in how to look for the places that may be impeding performance.
Adaptive Server locks the tables, data pages, or data rows currently used by active transactions by locking them. Locking is a concurrency control mechanism: it ensures the consistency of data within and across transactions. Locking is needed in a multiuser environment, since several users may be working with the same data at the same time.
