Where can I find my oracle home windows directory?

1.5K 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

Finding your Oracle Home directory in Windows is essential when configuring or troubleshooting Oracle software. Here’s how you can locate it:

1. Check Environment Variables

Open Command Prompt and type:

  echo %ORACLE_HOME%

If Oracle is installed correctly, this will return the Oracle Home path.

2. Use the Oracle Universal Installer (OUI)

Open Run (Win + R) and type:

  C:Program FilesOracleInventorylogsinstallActions.log

This log file contains the installation path, including Oracle Home.

3. Check the Windows Registry

Press Win + R, type regedit, and go to:

  HKEY_LOCAL_MACHINESOFTWAREOracle

Look for ORACLE_HOME under the installed Oracle products.

4. Find the Path in SQL*Plus or Command Line

Open Command Prompt and connect to Oracle using SQL*Plus:

  sqlplus / as sysdba

Run this SQL query:

  SELECT SYS_CONTEXT('USERENV', 'ORACLE_HOME') FROM dual;

5. Default Installation Locations

Common Oracle Home paths:

makefile

C:Oracleproductxx.x.xdbhome_x

C:ppAdministratorproductxx.x.xdbhome_x
