oracle 11g 角色口令

oracle 11g 中测试 拥有口令的角色


SYS@ sms> select * from v$version;

BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
CORE    11.2.0.4.0      Production
TNS for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production


1. 创建角色 role_01无密码 role_02 有密码


     SYS@ sms> create role role_01;
     
     Role created.
     
     
     SYS@ sms> create role role_02 identified by oracle;
     
     Role created.
     
     
     SYS@ sms> grant connect,create table to role_01;
     
     Grant succeeded.
     
     SYS@ sms> grant connect ,create view to role_02;
     
     SYS@ sms>  create user zhou identified by zhou1234   quota unlimited on users;
     
     User created.
     
     SYS@ sms> grant role_01,role_02 to zhou;
     
     Grant succeeded.
     
     
     SYS@ sms> grant role_01,role_02 to zhou;
     
     Grant succeeded.
     
     SYS@ sms> conn zhou/zhou1234
     Connected.
     ZHOU@ sms> create table t(id number);
     
     Table created.
     
     ZHOU@ sms> insert into t values(1);
     
     1 row created.
     
     ZHOU@ sms> commit;
     
     Commit complete.
     

2. 此时就出现问题了，role_02 明明有 create view 而且赋予给了 zhou 这里就没有呢？
   
   ZHOU@ sms> create view view_1 as select * from t;
   create view view_1 as select * from t
               *
   ERROR at line 1:
   ORA-01031: insufficient privileges
   

3. 查看 tyger_ro2 的default_role 为NO 难道 role_02 角色失效？？？
   ZHOU@ sms> col USERNAME for a20
   ZHOU@ sms> col GRANTED_ROLE for a20
   
   ZHOU@ sms> select USERNAME,GRANTED_ROLE,DEFAULT_ROLE from user_role_privs;
   
   USERNAME             GRANTED_ROLE         DEF
   -------------------- -------------------- ---
   ZHOU                 ROLE_01              YES
   ZHOU                 ROLE_02              NO
   
   
4. 再查看当前会话的权限，果然没有 create view 权限
    
    ZHOU@ sms> select * from session_privs;
    
    PRIVILEGE
    ----------------------------------------
    CREATE SESSION
    CREATE TABLE

5. 设置 tyger_ro2 权限生效

    
    ZHOU@ sms> set role role_02 identified by oracle;
    
    Role set.

6. 当前用户具有的权限不变

      ZHOU@ sms> select USERNAME,GRANTED_ROLE,DEFAULT_ROLE from user_role_privs;
      
      USERNAME             GRANTED_ROLE         DEF
      -------------------- -------------------- ---
      ZHOU                 ROLE_01              YES
      ZHOU                 ROLE_02              NO
      

7.当前会话用了 create view 权限 却没有了create table 权限
     
     ZHOU@ sms> select * from session_privs;
     
     PRIVILEGE
     ----------------------------------------
     CREATE SESSION
     CREATE VIEW
     
     ZHOU@ sms> create view view_1 as select * from t;
     
     View created.
     
     
     ZHOU@ sms> select * from tab;
     
     TNAME                          TABTYPE  CLUSTERID
     ------------------------------ ------- ----------
     T                              TABLE
     VIEW_1                         VIEW
     
     
8. 重新登录会话，权限恢复原样

       ZHOU@ sms> conn zhou/zhou1234
       Connected.
       ZHOU@ sms>  select * from session_privs;
       
       PRIVILEGE
       ----------------------------------------
       CREATE SESSION
       CREATE TABLE
       

总结：

在oracle 11g 中，带有口令的角色赋予用户，默认情况下是失效的，当 set role 生效后，其他角色所具有的权限失效， 只在当前会话有效
