In Oracle, a tablespace is a logical storage unit that contains data files. It is a way of organizing and managing data on a physical storage device. To ensure optimal performance and data integrity, it is crucial to monitor and manage tablespace size effectively.
There are several methods to check tablespace size in Oracle. One common approach is through the Oracle Enterprise Manager (OEM) graphical user interface (GUI). By navigating to the Storage tab and selecting Tablespaces, you can view a list of tablespaces along with their respective sizes.
