Expand Oracle Tablespace: Top Methods
There are several methods available for resizing Oracle database tablespaces:
- One way to increase the capacity of a tablespace is by adding data files. You can use the ALTER TABLESPACE statement to add data files. For example:
- Extend the size of the tablespace named ‘tablespace_name’ by adding a datafile at ‘file_path’ with a specified size.
- This will add a new data file to the specified tablespace and specify its size.
- Automatic expansion: You can configure the feature of automatic expansion of tablespace, which will automatically increase the data files when the space in the tablespace is running out. You can enable automatic expansion using the ALTER TABLESPACE statement, for example:
- Enable automatic resizing for tablespace “tablespace_name” by setting AUTOEXTEND ON.
- This will enable the automatic scaling function.
- Adjusting data file size: The size of data files can be modified using the ALTER DATABASE command. For example, you can use the following command to increase the size of a data file to a specified size:
- Change the size of the datafile located at ‘file_path’ in the database.
- Compressing Tablespaces: You can use Oracle’s compression feature to reduce the size of a tablespace. You can use the ALTER TABLESPACE statement to compress a tablespace, for example:
- Reduce the size of the tablespace named “tablespace_name”.
- This will compress the specified table space and release unused space.
It is important to note that when increasing tablespace, the size should be planned and adjusted based on actual needs and system resources to ensure the performance and stability of the database.
