Where are the oracle database tables?

Tables in Oracle database are stored in data files. Specific types include regular data files, temporary data files, rollback segment data files and undo data files. Data file naming follows a specific convention, for example, a common data file is datafile.dbf. Oracle manages data files using Automatic Storage Management (ASM), which stores data files in groups of physical disks. To determine the specific data file for a table, you can use a SQL query to retrieve the file ID, tablespace name, and file name.

Oracle Database Table Storage Location

Tables in Oracle Database are stored in data files. Data files are physical files used to store data in a database.

Data file types

There are many types of data files in Oracle:

• General data files: Store table and index data.
• Temporary data file: Stores sort operations and data in temporary tables.
• Rollback segment data file: Storage rollback segment, used to store data when a transaction is rolled back.
• Undo data file: Storage undo records, used to store temporary data in parallel queries.

File naming convention

The naming of data files follows the following convention:

• General data files:datafile< File number>.dbf
• Temporary data file:tempfile<Temporary table space number>.dbf
• Rollback segment data file: rollback<Rollback segment number>.rbs
• Undo data file:undo<Undo table space number>.dbf

# #Data File Management

Oracle uses Automatic Storage Management (ASM) to manage data files. ASM stores data files in groups of physical disks and abstracts away the complexities of file management.

Determine the table data file

To determine the table data file, you can use the following method:

SELECT file_id, tablespace_name, file_name
FROM dba_data_files
WHERE tablespace_name IN (SELECT tablespace_name FROM dba_tables WHERE table_name = '<table_name>');
