Additional considerations

  • DAS Professional Edition is subject to the following limits:

  • The default data storage duration of DAS Professional Edition is one month. You can change the storage duration after you purchase DAS Professional Edition. For more information, see Manage DAS Professional Edition.
    Note
    • After SQL Explorer is enabled for a database instance, the analytical and statistical data (excluding SQL details) generated by SQL Explorer can be stored for up to 90 days.
      • If you set the storage duration to less than 90 days when you enable DAS Professional Edition for the database instance, the analytical and statistical data (excluding SQL details) generated by SQL Explorer is stored for the specified duration.
      • If you set the storage duration to more than 90 days when you enable DAS Professional Edition for the database instance, the analytical and statistical data (excluding SQL details) generated by SQL Explorer is stored only for 90 days.
    • The storage duration of SQL details generated by SQL Explorer is the same as that specified when DAS Professional Edition is enabled for the database instance.
  • You can change the number of available instances that are supported by DAS Professional Edition. If you reduce the number of available instances, a refund is not provided. s
