Oracle Tips by Burleson 

Structure of dba_advisor_findings

The task_id field can be used to gather more information about a specific task.  These findings can be in one of four categories as shows in the type field:

  • Problem

  • Symptom

  • Error

  • Information

These categorizations provide a triage area to look at the PROBLEM items first.  These are the items where the type is set to the string PROBLEM.  A DBA allowing ADDM to advise on database performance issues will, ideally,  work their way down to review and address the INFORMATION items. 

The script show_addm_findings.sql will list the items in the PROBLEM category.  Figure 10.5 is a sample of the output from this script when dealing with a CPU bottleneck issue.
