How do I check my datafile size?
Size of Oracle database
- The size of the Oracle database files can be computed several ways: — get database size from v$datafile: select round((sum(bytes)/1048576/1024),2) from v$datafile;
- The size of the sum of table extents. select. segment_name table_name,
- The sum of the size of the data within the tables.
How do I find maximum size of tablespace?
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.
