Where is ORACLE_HOME Location

ORACLE_HOME is the location of Oracle database home directory path, which contains many important file relationship we may use them very often. To find the directory path, we need more information.

ORACLE_HOME Path in Windows OS

ORACLE_HOME Path in Linux or Unix-like OS

To check ORACLE_HOME in Linux or Unix-like OS (e.g. AIX, Solaris), the simplest way is to echo the environment variable $ORACLE_HOME for sure.

[oracle@test ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/19.3.0/dbhome_1

If there’s no such environment variable in your system, you can print oratab file if you know where it is.

[oracle@test ~]$ cat /etc/oratab
.
ORA19C1: /u01/app/oracle/product/19.3.0/dbhome_1 :Y

In the second field, it’s ORACLE_HOME.

RAC Database

Since oratab file may contain no information about ORACLE_HOME in a RAC database, you should use the server control utility (SRVCTL) to check.

[oracle@primary01 ~]$ srvctl config database -d orclcdb
Database unique name: ORCLCDB
Database name: ORCLCDB
Oracle home: /u01/app/oracle/product/19.0.0/db_1
Oracle user: oracle
Spfile: +DATA/ORCLCDB/spfile
Password file: +DATA/ORCLCDB/pwfile
.
