About Oracle Base Config

D.1.3 About Oracle Base Config

Both, in a read-only ORACLE_HOME and read/write ORACLE_HOME, the configuration files reside in a location known as ORACLE_BASE_CONFIG.

In a read/write ORACLE_HOME, the ORACLE_BASE_CONFIG path is the same as the ORACLE_HOME path because it is located at ORACLE_HOME. However, in a read-only ORACLE_HOME, the ORACLE_BASE_CONFIG path is the same as ORACLE_BASE.

ORACLE_BASE_CONFIG\dbs contains the configuration files for ORACLE_HOME. Each file in the dbs directory contains ORACLE_SID so that the directory can be shared by many different ORACLE_SIDs.

To print the ORACLE_BASE_CONFIG path, run the orabaseconfig command from the ORACLE_HOME\bin directory:

C:\> set ORACLE_HOME C:\app\oracle\product\19.0.0\dbhome_1
C:\> cd ORACLE_HOME\bin
orabaseconfig

For example:

orabaseconfig
C:\> C:\app\oracle

Where, C:\app\oracle is ORACLE_BASE.
