The interval between the moment when the system is ready for a transaction (for example, when a DCL prompt is printed) and when the transaction is started (for example, when the Return key is pressed). The time it takes to type a command is included in think time.
See also interactive transaction and response time.
(2) The amount of work done per unit time. Typical examples are system throughput (the number of transactions per second) or disk I/O throughput rate (the number of disk I/Os per second).
By default, transient processes are automatically assigned to the last defined (noninteractive) class provided this class is of type All and has a load limit of 0.0. If the last user-defined class does not have these characteristics, the tool automatically creates such a class for you. The name of the created class is CLASSn where n is one greater than the number of user-defined classes.
(2) Actual I/O due to direct program I/O requests rather than I/O requests supporting the memory management system.
(3) Real, physical I/O, excluding page fault I/O.
