About Oracle Base Homes
In a read-only ORACLE_HOME, the user-specific files, instance-specific files, and log files reside in a location known as the ORACLE_BASE_HOME.
Starting with Oracle Database 21c, the only available configuration is a read-only ORACLE_HOME where ORACLE_BASE_HOME and ORACLE_BASE_CONFIG are located separately from ORACLE_HOME.
In a read-only ORACLE_HOME, the ORACLE_BASE_HOME directory is not co-located with
ORACLE_HOME but is located at ORACLE_BASE\homes\HOME_NAME
.
Where, HOME_NAME is the internal name for ORACLE_HOME.
For example, the networking directories network\admin
, network\trace
, and network\log
are located in the ORACLE_BASE_HOME directory. In a read-only ORACLE_HOME, the networking directories are located in ORACLE_BASE\homes\HOME_NAME
.
