Distribution of the SAP DB Directories on the Hard
Disk
The ideal directory structure of the database system for Open Source [Page 74] depends on
the hardware configuration. There is no single solution or definition for the distribution of the
files of an SAP DB database instance [Page
132].
When attempting to find the optimum data distribution for your database environment in a
production system, bear in mind the information in the following sections:
• Security Requirements [Page
75]
• Performance Requirements [Page
76]
• Example Configuration [Page
77]
• Various Database Systems [Page
77]
• SAP DB Directories [Page

Security Requirements
Using the appropriate hardware, operating system, or database features can improve the
availability [Page
38] of a database instance [Page 132].
• Log volumes [Page
144]
In the production system, the log area [Page 142] should always be mirrored for
security.
