        Hi..

        I would suggest the below steps:-

        1. create a new temporary tablespace (TEMP2) with say 1GB size

        2. Make it as the default for the database.

        3. Drop the temp tablespace that was being used (big size) -- drop tablespace temp including contents; --> supposing temp as the name of the temporary tablespace

        NOTE:- Don't use " including contents and datafiles. "

        4. Recreate the temporary tablespace (temp) --> create temporary tablespace temp tempfile 'use/the/same/files/1' size xxxxM, 'use/the/same/files/2' size xxxxM;

        5. Drop the temp2 which you had made default. --> drop temporary tablespace temp2 including contents and datafiles;


        refer to smon not clearing my temp tablespace

          Hi,
          Below is the query I am using to check the free and available space on a tablespace:

          SELECT /* + RULE */ df.tablespace_name "Tablespace",
          df.bytes / (1024 * 1024) "Size (MB)",
          SUM(fs.bytes) / (1024 * 1024) "Free (MB)",
          Nvl(Round(SUM(fs.bytes) * 100 / df.bytes),1) "% Free",
          Round((df.bytes - SUM(fs.bytes)) * 100 / df.bytes) "% Used"
          FROM dba_free_space fs,
          (SELECT tablespace_name,SUM(bytes) bytes
          FROM dba_data_files
          GROUP BY tablespace_name) df
          WHERE fs.tablespace_name (+) = df.tablespace_name
          GROUP BY df.tablespace_name,df.bytes
          UNION ALL
          SELECT /* + RULE */ df.tablespace_name tspace,
          fs.bytes / (1024 * 1024),
          SUM(df.bytes_free) / (1024 * 1024),
          Nvl(Round((SUM(fs.bytes) - df.bytes_used) * 100 / fs.bytes), 1),
          Round((SUM(fs.bytes) - df.bytes_free) * 100 / fs.bytes)
          FROM dba_temp_files fs,
          (SELECT tablespace_name,bytes_free,bytes_used
          FROM v$temp_space_header
          GROUP BY tablespace_name,bytes_free,bytes_used) df
          WHERE fs.tablespace_name (+) = df.tablespace_name
          GROUP BY df.tablespace_name,fs.bytes,df.bytes_free,df.bytes_used
          ORDER BY 4 DESC;

          This query retrieves me the used space on the TEMP segment to be 100%.
          "free" and "used" in the context of v$temp_space_header do not mean "currently free for new operations" and "currently used by an operation", they just indicate whether the space has been allocated to a temporary segment or not. When a segment is created in the temporary tablespace it can be in use or not in use.

          Check V$TEMPSEG_USAGE to see the true current temporary segment usage: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2164.htm#REFRN30285

            Okay, so that means my query for determining the used and free space on all the tablespaces in a DB needs to be modified so as to reflect the actual values.

              Hi

              Use
              select tablespace_name,sum(bytes_used/1024/1024)  USEB_IN_MB,sum(bytes_free/1024/1024) FREE_IN_MB  from v$temp_space_header group by tablespace_name;

                  Also you can join ( v$sort_usage.SESSION_ADDR = v$session.SADDR) to know which session is consuming more temp.

                    Yes, the V$TEMPSEG_USAGE does not return me any rows. Also, when I try to execute the query on SQLPLUS, I am able to retrieve the results. But when I try running the same query through Business Objects using the Custom SQL option, i get the ORA-01652 error.
                    Sounds like you should set a trace like alter system set events '1652 trace name errorstack level 12'; so you can look at the trace file and see what sql actually is getting executed. Just to be sure it is the same SQL as the one you tried.

                        Yeah, all the space in the TEMP tablespace finally got frred up without requiring to bounce the database. We are able ti execute all the queries perfectly now. Thanks to all for all your help!! :)
