oracle實例管理中常用的命令

ALTER DATABASE db01 mount//open read only

置數據庫爲受限狀態：數據庫未啓動時：startup restrict           

                                       數據庫已啓動時：alter system enable restricted session；

強制關閉某些已連接的用戶：alter system kill session ‘SID,SERIAL#’;   （SELECT sid,serial# FROM v$session；）

創建一個數據庫用戶：

CREATE USER user
   IDENTIFIED { BY password
              | EXTERNALLY [ AS 'certificate_DN'  |  AS 'kerberos_principal_name' ]
              | GLOBALLY [ AS '[ directory_DN ]' ]
              }
   [ DEFAULT TABLESPACE tablespace
   | TEMPORARY TABLESPACE
        { tablespace | tablespace_group_name }
   | { QUOTA { size_clause | UNLIMITED } ON tablespace }...
   | PROFILE profile
   | PASSWORD EXPIRE
   | ACCOUNT { LOCK | UNLOCK }
     [ DEFAULT TABLESPACE tablespace
     | TEMPORARY TABLESPACE
          { tablespace | tablespace_group_name }
     | { QUOTA { size_clause | UNLIMITED } ON tablespace }...
     | PROFILE profile
     | PASSWORD EXPIRE
     | ACCOUNT { LOCK | UNLOCK }
     | ENABLE EDITIONS
     ]...
  ] ;

然後授權用戶：grant
