Operating system access restriction
Usually, in a database environment, the database administrator (DBA) accesses the server to install and manage the database. They will create the necessary data files and then load the data into the database. DBAs and system administrators also access the servers to perform day-to-day maintenance tasks, such as database backup generation, archive logs generation, data files growth, and rectifying physical corruption. They also access the operating system structure to perform the scaling of the CPU, memory, and storage. Here, in the Autonomous Database, the provisioning and management are automated. All database management tasks are taken care of automatically. Hence, Autonomous Database only provides database connectivity. The underlying operating system is not accessible from the outside. We can’t connect the database server via SSH. The Autonomous Database server is secured and managed by Oracle.
