What Editions Does DBSS Provide?

DBSS provides security audit, security O&M, and security encryption specifications for you to choose from.

A database instance is uniquely defined by its database IP address and port.
The number of database instances equals the number of database ports. If a database IP address has N database ports, there are N database instances.

Example: A user has two database IP addresses, IP₁ and IP₂. IP₁ has a database port. IP₂ has three database ports. IP₁ and IP₂ have four database instances in total. To audit all of them, select professional edition DBSS, which supports a maximum of six database instances.
To change the edition of a DBSS instance, unsubscribe from it and purchase a new one.
The table above lists the system resources consumed by a database audit instance. Ensure your system has the required configurations before purchasing database audit instances.
Online SQL statements are counted based on the assumption that the capacity of an SQL statement is 1 KB.

Security audit comes in four editions: starter, basic, professional, and advanced. For details, see Table 1.
