AWR report is reporting "UNAVAILABLE", "UNDEFINED" values in RAC environment
I am working on resolving performance issues for a critical application. While investigating the AWR report, I see there are entries lilke "UNAVAILABLE", "UNDEFINED" values under "segments physical reads" section of AWR report.
I am not an export on RAC environment, is this normal for RAC ?. If so, what makes up these values. I would really appreciate if someone can answer my question.
Your time and advice is always valued.
