Oracle Tablespaces: An In-Depth Guide on How to Check Their Usage

December 10, 2025 by admin

Inside an Oracle database, a tablespace is a logical storage unit composed of a number of knowledge recordsdata. Several types of Oracle database objects, comparable to tables, indexes, and non permanent segments, can reside in a tablespace. Checking the tablespace is essential as a result of it helps the database administrator (DBA) monitor the area utilization, determine potential points, and guarantee optimum efficiency of the database.

There are a number of methods to verify tablespace in Oracle, together with utilizing Oracle Enterprise Supervisor, SQL queries, and working system instructions. Oracle Enterprise Supervisor supplies a graphical consumer interface (GUI) that permits DBAs to simply view and handle tablespaces, together with their dimension, utilization, and standing. SQL queries can be used to retrieve details about tablespaces, comparable to the next question that shows the scale and utilization of all tablespaces within the database:

SELECT tablespace_name, total_space, ROUND((used_space / total_space) * 100, 2) AS pct_used FROM dba_tablespaces;
