Which of the following is the root directory for oracle?
-
ORACLE_HOME

ORACLE_BASE
-
ORACLE_SERVER
C
Correct answer
Explanation
ORACLE_BASE is the root-level Oracle directory that serves as the base for the Oracle software installation. It contains the Oracle software inventory, administrative files, and diagnostic directories. ORACLE_HOME is a subdirectory beneath ORACLE_BASE that contains the actual Oracle software binaries for a specific product installation. ORACLE_ROOT and ORACLE_SERVER are not standard Oracle environment variables. The typical structure is ORACLE_BASE (root) -> ORACLE_HOME (product-specific software) -> database files and administrative directories.
