Best Practices

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:
