--查看表空间被占用情况

SELECT se.USERNAME,

sid,
serial#,
sql_address,
machine,
program,
tablespace,
segtype,
contents
FROM v$session se,
v$sort_usage su

WHERE se.saddr=su.session_addr

--查看表空间是否为自动增长

select tablespace_name,AUTOEXTENSIBLE,INCREMENT_BY from dba_data_files;

--查看表是否锁定

--查看表锁定情况（方法1）
select object_id,session_id,locked_mode from v$locked_object;

--查看表锁定情况（方法2）
select b.owner,b.object_name,l.session_id,l.locked_mode
from v$locked_object l, dba_objects b
where b.object_id=l.object_id

--找出数据库的serial#,以备杀死
select t2.username,t2.sid,t2.serial#,t2.logon_time
from v$locked_object t1,v$session t2
where t1.session_id=t2.sid order by t2.logon_time;

--查看表索引情况

select *--t.index_name,t.index_type,t.include_column,t.tablespace_name,t.table_name
FROM index_stats T --where t.index_name='R164_SDE_ROWID_UK'
/*WHERE t.table_owner = 'HNLY_LQGG'
AND t.table_name = 'HNLY10K_LQRH_XBM';*/

--杀死该session
alter system kill session 'sid,serial#'

--查询表空间利用情况
