Component documentation Database Parameters Locate the document in its SAP Library structure

Use database parameters to define various characteristics of the SAP DB database instance. When you install the database software, a default configuration is stored. This configuration is basically runnable. If necessary, you can adjust the database parameters originally set to suit any specific requirements you may have.

Alternatively, you can use the configuration of a database instance already present on the host or the configuration from a complete data backup. Even after this you can still adjust the database parameters to suit your own requirements.

The database parameters are divided into the following groups:

·        General database parameters

·        Special database parameters

·        Support database parameters

Note

Support parameter do not need to be and should not be changed for normal database operation. The setting of these database parameters requires a detailed knowledge of the database system, and should therefore only be carried out by the SAP DB Support team.

Displaying and Changing Database Parameters

You can use the Database Manager to display or change database parameters.

·        Displaying and Changing Database Parameters with the Database Manager GUI

·        Configuring Database Instances with the Database Manager CLI

Caution

Changes take effect only after you have restarted the database instance.
