Background documentation Database Instance Locate the document in its SAP Library structure

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

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

Note

For information on the installation of the database software, see the Installation Guide and Installation Manual.

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

In SAP systems, you can also use the DBA functions of the CCMS (CCMS: MySQL MaxDB) for the administration of your database.

Structure of the Database Instance

Each database instance consists of the following parts:

·        Threads

·        Caches

·        Volumes (physical storage units)

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

·        Database catalog

·        Application data

The system tables contain information about the database instance, database objects, and structures, as well as status information.
