Params Optimize

Updated at: Mar 20, 2020 GMT+08:00


Combining the current performance data, the system uses AI to forecast a set of parameter settings suitable to your instance.

  • Only RDS DB instances support this function. Self-built databases on ECSs do not.
  • The intelligent forecast and analysis program provides a recommendation for each node of the current instance.
  • Only RDS MySQL instances with 2 vCPUs or above are supported currently. You need to enter the login username and password and click Remember Password.
  • The intelligent forecast and analysis program is a background scheduled task, which is executed once an hour. The recommended result may be delayed. Please wait.


You have logged in to the DAS console.


  1. On the top menu bar, choose Cloud DBA > Params Optimize.
  2. On the displayed page, all the diagnosis records of the current instance are displayed, and you can search for the diagnosis by time range.

    When you set up a connection on DAS and remember the account and password, the system automatically performs intelligent parameter diagnosis.

    Diagnosis records are saved for 15 days by default.

  3. Delete the diagnosis records as required.

    Deleted records cannot be recovered. Exercise caution when performing this operation.
