  • Oracle查询临时表空间

    1、查看临时表分区

    SELECT *
      FROM (SELECT USERNAME,
                   SESSION_ADDR,
                   SQL_ID,
                   CONTENTS,
                   SEGTYPE,
                   BLOCKS * 8 / 1024 / 1024 GB
              FROM V$SORT_USAGE
             ORDER BY BLOCKS DESC)
     WHERE ROWNUM <= 200;

    2、查看临时表空间

    select *
      from (Select a.tablespace_name,
                   to_char(a.bytes / 1024 / 1024, '99,999.999') total_bytes,
                   to_char(b.bytes / 1024 / 1024, '99,999.999') free_bytes,
                   to_char(a.bytes / 1024 / 1024 - b.bytes / 1024 / 1024,
                           '99,999.999') use_bytes,
                   to_char((1 - b.bytes / a.bytes) * 100, '99.99') || '%' use
              from (select tablespace_name, sum(bytes) bytes
                      from dba_data_files
                     group by tablespace_name) a,
                   (select tablespace_name, sum(bytes) bytes
                      from dba_free_space
                     group by tablespace_name) b
             where a.tablespace_name = b.tablespace_name
            union all
            select c.tablespace_name,
                   to_char(c.bytes / 1024 / 1024, '99,999.999') total_bytes,
                   to_char((c.bytes - d.bytes_used) / 1024 / 1024, '99,999.999') free_bytes,
                   to_char(d.bytes_used / 1024 / 1024, '99,999.999') use_bytes,
                   to_char(d.bytes_used * 100 / c.bytes, '99.99') || '%' use
              from (select tablespace_name, sum(bytes) bytes
                      from dba_temp_files
                     group by tablespace_name) c,
                   (select tablespace_name, sum(bytes_cached) bytes_used
                      from v$temp_extent_pool
                     group by tablespace_name) d
             where c.tablespace_name = d.tablespace_name)
     order by tablespace_name ;
