Hi,
We have a 11.2 SE db that is experiencing big spikes in CPU. Upon further
investigation I see one SQL that has become resource intensive in terms of
buffer gets and CPU time. The SQL was running fine till few days ago even
though it was being executed several tens of 1000s of times in the half hr
reporting period. Per the old reports, this sql has been executed that many
times always. But something changed few days ago that this SQL shot up in
terms of # of buffer gets per the report. I tried checking the v$sql for
different versions today, but I see only one version of the SQL (remembered
that from Jonathan's advise last time). Is there a way with SE to see the
equivalent of awrddrpt?
also, I see the dbfile seq read double in value suddenly in the newer
reports to about 26ms. Even though that is not a great number, the previous
average was about 12/13ms. I am thinking the increase in the DBF SEQ RD
time could not cause the increased buffer gets. Am I right in my assumption.
Thanks,
Ram
