Chapter 3, “Global Variables,” includes the following global variables, which return the values in ticks, but were described erroneously as returning the values in seconds. Replace the descriptions in the chapter with the following text:
@@idle – returns the amount of time, in ticks, that Adaptive Server has been idle since it was last started.
@@cpu_busy – returns the amount of time, in ticks, that the CPU has spent doing Adaptive Server work since the last time Adaptive Server was started.
@@io_busy – returns the amount of time, in ticks, that Adaptive Server has spent doing input and output operations.
