In Oracle databases, temporary tablespace is used to store temporary data, usually for sorting, joining, grouping operations, etc. The release of temporary tablespace can be done through the following steps:<\/p>\n

    \n
  1. current session<\/li>\n
  2. The sorting usage in the system.<\/li>\n<\/ol>\n
    SELECT s.sid, s.serial#, s.username, u.tablespace_name\r\nFROM v$session s, v$sort_usage u\r\nWHERE s.saddr = u.session_addr;\r\n<\/code><\/pre>\n
      \n
    1. Terminate a session within the system.<\/li>\n<\/ol>\n
      ALTER SYSTEM KILL SESSION '123,123';\r\n<\/code><\/pre>\n
        \n
      1. transaction value<\/li>\n<\/ol>\n
        SELECT * FROM v$transaction;\r\n<\/code><\/pre>\n
        If there are any pending transactions, you can try rolling back or committing them.<\/p>\n
          \n
        1. If there are no active sessions using temporary tablespace and no pending transactions, you can perform the following steps to release the temporary tablespace:<\/li>\n<\/ol>\n
            \n
          1. First, switch to the tablespace where the temporary tablespace is located.<\/li>\n<\/ol>\n
            ALTER TABLESPACE temp;\r\n<\/code><\/pre>\n
              \n
            1. Next, use the ALTER DATABASE DATAFILE statement to shrink or delete the data files of the temporary tablespace. For example, shrink the data file to a specified size:<\/li>\n<\/ol>\n
              ALTER DATABASE DATAFILE '\/path\/to\/tempfile.dbf' RESIZE 100M;\r\n<\/code><\/pre>\n
              Alternatively, delete the data files.<\/p>\n
              ALTER DATABASE DATAFILE '\/path\/to\/tempfile.dbf' OFFLINE DROP;\r\n<\/code><\/pre>\n
                \n
              1. Finally, you can use the ALTER TABLESPACE statement to delete the temporary tablespace.<\/li>\n<\/ol>\n
                DROP TABLESPACE temp INCLUDING CONTENTS;\r\n<\/code><\/pre>\n
                Note: Before performing the above operation, make sure to back up the database to prevent data loss or damage.<\/p>\n","protected":false},"excerpt":{"rendered":"
