Where can I find my oracle home windows directory?

1.0K Asked by ranjan_6399 in SQL Server , Asked on Feb 7, 2023

I'm trying to find my listener.ora file to edit it, but the docs say it's in the ORACLE_HOME directory, but where is that?

I'm running 12.1.0 on Windows Server 2008

To find your oracle home windows directory, Open up a command prompt

Start -> Run -> "cmd.exe"

Start sqlplus as administrator

sqlplus / as sysdba

There's a system stored procedure called get_env for retrieving the value for ORACLE_HOME, thanks Sabdar Syed for the query.

SQL > var OHM varchar2(100);

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

SQL > PRINT OHM

Should return a path like this:

C:pporacle_accountproduct

.1.0dbhome_1

To find your Oracle Home directory on Windows, follow these steps:

Environment Variables:

Open Command Prompt.
Type echo %ORACLE_HOME% and press Enter.
This will display the Oracle Home directory if it is set as an environment variable.

Registry:

Open the Registry Editor by typing regedit in the Run dialog (Win + R).
Navigate to HKEY_LOCAL_MACHINESOFTWAREOracle.
Look for the key named ORACLE_HOME which contains the path.

Oracle Universal Installer:

Launch Oracle Universal Installer (OUI).
Go to Installed Products to view the Oracle Home directory.

Oracle Configuration Files:

Check configuration files such as tnsnames.ora, listener.ora, or sqlnet.ora located in the networkdmin subdirectory of Oracle Home.

By using these methods, you can locate your Oracle Home directory on a Windows system.
