Oracle Database Data Storage Directory

Oracle Database stores data in files called data files, which reside in specified directories. The location of the data file directory varies by operating system:

Windows

• ##C:\oracle\oradata\ (default)
Can be changed by modifying the
• ORACLE_BASE value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME[n].

Unix/Linux

• /u01/app/oracle/oradata/(Default)
Can be changed by editing the
• init.ora or spfile file and setting the DB_CREATE_FILE_DEST parameter.

Note:

Each database has its own data file directory.
• The data file directory should have enough space to store database data and grow.
• The data file directory should be secure and accessible only to authorized users.
• It is recommended to use a dedicated partition or volume to store data files to improve performance.

Data file naming convention

• system01.dbf, system02.dbf, ...: system table space data file
##undotbs01.dbf
• , undotbs02.dbf, ... : Undo table space data files
users01.dbf
• , users02.dbf, ...: User table space data files

You can use the following SQL query to view the data file directory of the current database:

<code>SELECT name, create_date, bytes, DIRECTORY_PATH
FROM sys.dba_data_files;</code>
