Background documentation Directory Structure of the Database System Locate the document in its SAP Library structure

How the directories required for the database system are distributed to the available hard disks has a significant impact on the security and performance of your database system. The optimum design of the directory structure depends upon the specified hardware configurations. The distribution must meet the following requirements:

·        There must be enough free space to allow the database to expand.

·        The data must be stored securely.

·        The hardware must meet the performance requirements.

When you distribute the files for your database environment in a production system, note the information in the following sections:

·        Performance Requirements

·        Different Database Systems

·        Database Directories

·        Availability

Defining the Directories

The database directories are defined either in database parameters (see Run Directory) or when you install the database software (see Installation Manual).

Note

You do not have a free choice of directories for an RPM-based installation on Linux; instead, the directories are specified by the defaults /var/opt/sdb/data , /opt/sdb/programs, and /opt/sdb/7500.

Displaying the Directories

Use the Database Manager CLI to display the paths of the database directories.
