8. Click Next to switch to the Configure Data Masking Period page and configure the data masking period.

   Select and set the execution period of a masking task.

   • Manual: Manually enable a masking task and execute it based on masking rules.
   • Hourly: Execute a data masking task every several hours.

     Example: If the masking task needs to be executed every two hours, set this parameter to 02:00.

   • Daily: Execute a data masking task at a specified time every day.

     Example: If the masking task needs to be executed at 12:00 every day, set this parameter to 12:00:00.

   • Weekly: Execute a data masking task at a specified time every week.

     Example: If the masking task needs to be executed at 12:00 every Monday, set this parameter to 12:00:00 every Monday.

   • Monthly: Execute a data masking task at a specified time on a specified day every month.

     Example: If the masking task needs to be executed at 12:00 on the 12th day of each month, set this parameter to 12:00:00 12th day of every month.

     

     If you want to execute a data masking task on the 31st day of each month, the system automatically executes the task on the last day of every month.

9. Click Next. The Set Target Data page is displayed.
   1. Select a database instance and database name, and enter the database table name.
