Various Database Systems
For performance reasons, the SAP DB database system should not be installed on the same
computer along with other database systems.
IF you want to install several SAP DB database instances [Page
132], then every database
instance should be installed on a separate computer. This will allow you to deal with possible
performance problems more easily.
SAP DB Directories
The following table contains the distribution of the SAP DB directories on the hard disk [Page
75] for a SAP DB database instance [Page 132].
