1. The size of the lookup table space remaining bytes
the SELECT TABLESPACE_NAME, the SUM (BYTES) / 1024/1024 the AS "the FREE the SPACE (M)"
the FROM DBA_FREE_SPACE
the WHERE TABLESPACE_NAME = '& tablespace_name'
the GROUP BY TABLESPACE_NAME;
Note: If the temporary table space, consult DBA_TEMP_FREE_SPACE
the SELECT tABLESPACE_NAME, FREE_SPACE / 1024/1024 the AS "the FREE the SPACE (M)"
the FROM DBA_TEMP_FREE_SPACE
the WHERE tABLESPACE_NAME = '& tablespace_name';
2. Query table space for all data file paths
the SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES / 1024/1024 the AS "BYTES (M)"
the FROM the DBA_DATA_FILES
the WHERE TABLESPACE_NAME = '& tablespace_name';
Note: If the temporary table space, query DBA_TEMP_FILES
the SELECT TABLESPACE_NAME , FILE_ID, FILE_NAME, BYTES / 1024/1024 the AS "the SPACE (M)"
the FROM DBA_TEMP_FILES
the WHERE tABLESPACE_NAME = '& tablespace_name';
3. Add a data file is insufficient space table space
ALTER TABLESPACE & tablespace_name ADD DATAFILE '& datafile_name' SIZE 2G;
Note: If you want to temporary table space expansion, use the following statement
ALTER TABLESPACE & tablespace_name ADD TEMPFILE '& datafile_name' SIZE 2G;
4. Check the size of the temporary table space data file path and
the SELECT TABLESPACE_NAME, FILE_ID, FILE_NAME, BYTES / 1024/1024 the AS "the SPACE (M)"
the FROM DBA_TEMP_FILES
the WHERE TABLESPACE_NAME = 'the TEMP';
or
select name, bytes / 1024/1024 as "size (M)" from v $ tempfile order by bytes;
5. rebuild and modify the default temporary table space way:
- query the current database default temporary table space name
the SELECT * from DATABASE_PROPERTIES the WHERE property_name = 'DEFAULT_TEMP_TABLESPACE';
- create a new temporary tablespace
create temporary tablespace temp02 tempfile 'E: \ oracle \ oradata \ LIMS \ TEMP02.DBF 'size 1024M AUTOEXTEND ON;
- modify the default table space for just created temporary table space for
the ALTER tABLESPACE temp02 the temporary Database default;
- view the user temporary table space with the situation
SELECT USERNAME, tEMPORARY_TABLESPACE FROM DBA_USERS ;
- delete the original temporary table space
drop the TEMP tABLESPACE Including Contents and the Datafiles;
- see all table space to confirm whether the temporary table space is deleted
the SELECT tablespace_name from
dba_tablespaces; -------------- -
the Oracle data files deleted
table space alter tablespace drop datafile 'data files path';
If you want to delete the temporary files, you can use the following command
alter tablespace temporary table space name drop tempfile 'temporary file location';
you can also use the following command to delete the temporary files
alter database tempfile 'temporary file path' drop including datafiles;
