Thank you. ------------------------------- * Oracle states that even long-running SQL resource consumption will be accurate to within 5 seconds. But be warned: while the ASH views are queryable at any time, to legally query the views, an additional license is required.2 I am confident Oracle will continue to provide both new and improved performance diagnostic capabilities. For example, Oracle is now allowing operating system activity to be viewed through its performance views (for example, v$osstat).
