This article aims to provide guidance on how to interpret AWR information specifically for Database Performance issues.
Please remember in order to produce reports, access AWR views, or use the diagnostic information from any part of the Automatic Workload Repository, the Diagnostic Pack License is required. This includes the production of AWR reports, ADDM reports and ASH reports even if these are requested by product support or other agencies.
NOTE: Oracle Diagnostics Pack (and Oracle Tuning Pack) is available with Enterprise Edition ONLY. For further details of pack licensing see:
Pro-Active Problem Avoidance and Diagnostic Collection
Although some problems may be unforeseen, in many cases problems may be avoidable if signs are detected early enough. Additionally, if an issue does occur, it is no use collecting information about that issue after the event. AWR reports are one of the support recommend methods for collecting such diagnostics. For information on suggested uses, other proactive preparations and diagnostics, see:
