Oracle Database Administration from Zero to Hero - Managing Tablespaces (Part 1 of 4)

This lecture covers the basics of tablespace management in Oracle databases. It explains different types of tablespaces, including system, SYS, UNDO, temporary, and permanent tablespaces. The lecture focuses on managing permanent tablespaces and discusses extent management methods, such as dictionary-managed and locally-managed tablespaces. It also provides guidance on creating tablespaces using SQL, managing data files, and segment space management options. The lecture emphasizes the importance of understanding tablespace attributes and best practices for efficient database management.

What is the primary function of a system tablespace?

• To store user data

• To store temporary data

• To save objects needed for database operations

• To manage undo blocks

Which tablespace type is used for storing undo blocks?

What happens if a permanent tablespace becomes unavailable?

• The database features fail completely

• The database engine stops functioning

• Application users may complain, but the database engine continues

• The system tablespace takes over its functions

• Globally managed

Which keyword is used to define the full name of the data file within a tablespace?

• File

• Filepath

• Filename

• Datafile

What does the 'auto extend' option do when set to ON?

• Allows the data file to expand automatically

• Deletes old data to make space

• Limits the data file to a fixed size

• Prevents the data file from expanding

What is the recommended setting for the Max size of a data file?

• Zero

• A specific maximum size

• Unlimited

• Equal to the initial size

What is the default behavior for segment space management in Oracle tablespaces?

• Manual

• User-defined

• Automatic

• Semi-automatic

Which option provides more control over segment storage in extent management?

• Fixed allocation

• Dynamic allocation

• Uniform size

• Auto allocate

What is the purpose of the 'uniform size' option in extent management?

• To allow variable extent sizes

• To set a fixed size for all extents

• To disable extent management

• To automatically adjust extent sizes
