Find ORACLE_HOME

Oracle Database Tips by Donald BurlesonSeptember 8, 2015


Question:
 I wish to display my ORACLE_HOME variable.  How do I find the value of ORACLE_HOME?

 

Answer:  There are several commands, some internal and some external to Oracle that will find your current ORACLE_HOME.  Within Oracle SQL*Plus, the following SQL command script will display the value of your ORACLE_HOME:

SQL > var OH varchar2(200);

SQL > EXEC dbms_system.get_env('ORACLE_HOME', :OH) ;

SQL > PRINT OH

There are also external commands that show the current settings for the ORACLE_HOME variable.

On most UNIX distributions (AIX, Solaris Linux and HP/UX) you can use the env and echo commands to find the current setting for your ORACLE_HOME. where ORACLE_HOME is set-up as an environmental variable.

$ env|grep -i ORACLE_HOME

/u01/app/oracle/product/10gR2/db_1

$ echo ORACLE_HOME

/u01/app/oracle/product/10gR2/db_1

For other OS environments there ORACLE_HOME is not defined as a variable, you can find the ORACLE_HOME directory with these command sets:

AIX: Display ORACLE_HOME

$ ps -ef | grep pmon

ora1024   262366        1   0   Mar 23      -  0:12 ora_pmon_mysid
 
ORACLE_SID is mysid
 
$ ls -l /proc/262366/cwd

lr-x------   2 ora1024  dba  0 Mar 23 19:31 cwd -> /data/opt/app/product/10.2.0.4/db_1/dbs/
 
ORACLE_HOME is /data/opt/app/product/10.2.0.4/db_1

 



Linux & Solaris:Display ORACLE_HOME

$ pgrep  -lf _pmon_

12546 ora_pmon_mysid
 
ORACLE_SID is mysid
 
$ pwdx 12546

12586: /u01/oracle/10.2.0.4/ee1/dbs


HP/UX: Display ORACLE_HOME


$ ps -ef | grep pmon
 
ora1024 25441     1  0  Mar 21  ?         0:24 ora_pmon_itanic10
 
ORACLE_SID is itanic10
 
$ pfiles 25441 | grep  bin
 
25441:                  /opt/ora/app/db_1/bin/oracle
 
ORACLE_HOME is /opt/ora/app/db_1
