Once you have installed the SAP DB software on a host, you can set up and operate one or more database instances on that host.

When creating a database instance, you can choose between different database instance types, depending on your requirements.

Note

To create and manage your database instance, use the Database Manager database tool.

Structure of the Database Instance

Every database instance consists of threads, main memory structures (caches) and volumes.

Each database instance differentiates between the following areas for the logical storage of data:

·        Database catalog

·        Application data
