We can query the DBA_DATA_FILES view to check whether the data file is in AUTOEXTEND mode. SQL> select tablespace_name, file_name, autoextensible from dba_data_files; To confirm whether the maxsize is set to UNLIMITED we have to check for the maximum possible size, as there is no concept of an ‘UNLIMITED’ file size.

Another database can have three tablespaces, each consisting of two datafiles (for a total of six datafiles).
Is it better to store data in bigfile or smallfile?
Performance of database opens, checkpoints, and DBWR processes should improve if data is stored in bigfile tablespaces instead of traditional tablespaces. However, increasing the datafile size might increase time to restore a corrupted file or create a new datafile.
