Dashtop Running long time #36

Closed balaoracle2021 closed 2 years ago

Hi Tanel,

Thank you for the mind blowing scripts. When i run dashtop in one of our 19c database it runs for long time so i cancelled it and checked the Execution and found that WRH$_active_session_history (table access by index local row id) spends user io 90% of time and that table is in stale stats including index though 1week before we gathered stats after the upgrade to 19c. Please suggest to fix it
