How do you find the maximum size of a tablespace?

So the right query is: select TABLESPACE_NAME, sum(decode(AUTOEXTENSIBLE, ‘YES’, MAXBYTES, BYTES)) MAX_SIZE from DBA_DATA_FILES group by TABLESPACE_NAME; This has been tested on 11g but it should also work on 10g. It gives you the maximum size of each tablespace in bytes.

What is a tablespace in Oracle 11g?

An Oracle database consists of one or more logical storage units called tablespaces, which collectively store all of the database’s data. Each tablespace in an Oracle database consists of one or more files called datafiles, which are physical structures that conform to the operating system in which Oracle is running.

  • Temporary.

  4. df. totalspace “Total MB”,
  5. ROUND(100 * ( (df. totalspace – tu.

  2. The size of the sum of table extents. select. segment_name table_name,
  3. The sum of the size of the data within the tables.

How do I find the size of an Oracle database?

The size of the database is the space the files physically consume on disk. You can find this with: select sum(bytes)/1024/1024 size_in_mb from dba_data_files; But not all this space is necessarily allocated.

What is a tablespace quota?

– A tablespace is a logical storage unit within an Oracle database because it is not visible in the file system of the machine, the database resides on. – The Tablespace quotas are used to assign users with limited size on tablespaces.
