ORCALE基本操作

創(chuàng)建表空間

CREATE SMALLFILE TABLESPACE TTKDTEST datafile '/opt/oracle/oradatas/otwb/dbf.DMP' SIZE 100M REUSE AUTOEXTEND ON NEXT 2048K  MAXSIZE UNLIMITED LOGGING  EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;

刪除test用戶

drop user wmsloc cascade;

創(chuàng)建test用戶

create user wrtest identified by wrtest;

授權(quán)test用戶

grant connect,resource,dba to wrtest;

--選擇性授權(quán)

grant select on sy_user to user

commit;

更改表空間

select 'alter table  '|| table_name ||'  move tablespace tablespacename;'  from user_all_tables; 

select 'alter index '|| index_name ||' rebuild tablespace tablespacename;' from user_indexes; 

重建索引

select 'alter index '|| index_name ||' rebuild;' from user_indexes; 

正在運(yùn)行的SQL

SELECT b.sid oracleID,  

b.username 登錄Oracle用戶名,  

b.serial#,  

spid 操作系統(tǒng)ID,  

paddr,  

sql_text 正在執(zhí)行的SQL,  

b.machine 計(jì)算機(jī)名  

FROM v$process a, v$session b, v$sqlarea c  

WHERE a.addr = b.paddr  

AND b.sql_hash_value = c.hash_value and b.username='TMS'

   --查出oracle當(dāng)前的被鎖對(duì)象

SELECT l.session_id sid,

       s.serial#,

       l.locked_mode 鎖模式,

       l.oracle_username 登錄用戶,

       l.os_user_name 登錄機(jī)器用戶名,

       s.machine 機(jī)器名,

       s.terminal 終端用戶名,

       o.object_name 被鎖對(duì)象名,

       s.logon_time 登錄數(shù)據(jù)庫(kù)時(shí)間

FROM v$locked_object l, all_objects o, v$session s

WHERE l.object_id = o.object_id

   AND l.session_id = s.sid

ORDER BY sid, s.serial#;
