1. 查询表空间剩余字节大小
SELECT TABLESPACE_NAME, 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, query 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 . All spatial lookup table 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 . a tablespace is insufficient to increase the data files
The ALTER TABLESPACE & tablespace_name the ADD DATAFILE ' & datafile_name ' SIZE 2G; 
Note: If you want to expansion temporary table space, use the following statement 
the ALTER TABLESPACE & tablespace_name the ADD TEMPFILE ' & datafile_name ' SIZE 2G; 

. 4 View size and data file path temporary table space.
 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 the Order  by bytes; 

5 rebuild and modify the default temporary table space way:
 - query the current database default temporary table space 
select  *  from DATABASE_PROPERTIES the WHERE property_name = ' DEFAULT_TEMP_TABLESPACE ' ;
 - create a new temporary table space for 
the create  the temporary tABLESPACE temp02 tempfile ' E: \ the Oracle \ oradata \ LIMS \ TEMP02.DBF ' size 1024M AUTOEXTENDON ;
 - modify the default table space for just created temporary table space for 
the ALTER  Database  default  the Temporary TABLESPACE temp02;
 - view the user of temporary table space with 
the SELECT USERNAME, temporary_tablespace the FROM DBA_USERS;
 - delete the original temporary table space 
drop TABLESPACE the TEMP Contents Including and the Datafiles;
 - see all table space to confirm whether the temporary table space is deleted 
the SELECT tablespace_name from dba_tablespaces;
