How to handle a full Oracle table space.

When an Oracle tablespace becomes full, you can take the following actions:

1. To increase the size of the tablespace, you can use the ALTER TABLESPACE statement. For example, you can add more space to a tablespace by using the syntax: ALTER TABLESPACE tablespace_name ADD DATAFILE ‘file_path’ SIZE size.
2. Cleanup space: You can free up space by removing redundant data from the table space. You can use DELETE or TRUNCATE statements to delete unwanted data, or use the DROP TABLE statement to remove the entire table.
3. Compress table space: You can reduce the size of table space by using Oracle’s compress table space feature. Use the ALTER TABLE statement with the COMPRESS keyword to compress table space.
4. Moving data to another tablespace can free up space by transferring data from a full tablespace to another space. You can use the ALTER TABLESPACE statement to move tables or indexes in a tablespace to another tablespace.
5. Add data file: If the data files of a tablespace are full, you can expand the tablespace by adding new data files. Use the ALTER TABLESPACE statement with the ADD DATAFILE keyword to add a new data file.
6. Database partitioning: consider using Oracle’s partitioning feature to distribute data across multiple tablespaces in order to avoid issues with a single tablespace becoming full.

Regardless of the method chosen, it is necessary to evaluate and make decisions based on the actual situation, while also carefully operating to avoid causing irreversible damage to the database.
