测试DBMS_SCHEDULER

需要用到Oracle的job,于是看了文档，很长，和详细，可惜没有看到一个简单的从头至尾的例子。

 

27 Using the Scheduler

Oracle Database provides database job capabilities through Oracle Scheduler (the Scheduler). This chapter explains how touse the various Scheduler components, and discusses the following topics:

• Scheduler Objects and Their Naming

• Using Jobs

• Using Programs

• Using Schedules

• Using Job Classes

• Using Windows

• Using Window Groups

• Using Events

• Using Chains

• Allocating Resources Among Jobs

 

本地做了一个小测试，很简单。

-- 1. The procedure
create or replace procedure sp_test is
begin
  insert into testtab(ddl_txt)
  values ('a');
  commit;
end sp_test;
/

-- 2. The job and schedule.
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
   job_name           =>  'test_job',
   job_type           =>  'STORED_PROCEDURE',
   job_action         =>  'sp_test',
   start_date         =>  sysdate,
   repeat_interval    =>  'FREQ=MINUTELY;INTERVAL=1',
   comments           =>  'test job');
END;
/

exec DBMS_SCHEDULER.ENABLE('test_job');

就可以了。

 

 ===== 后记

需要“MANAGE SCHEDULER”的系统权限

 

查看如下：

select *  from role_sys_privs where privilege = 'MANAGE SCHEDULER';

 

授权如下：

SQL> grant SCHEDULER_ADMIN to xxxx;
 
Grant succeeded
 
SQL>

SQL> select * from role_sys_privs a where a.privilege = 'MANAGE SCHEDULER';
 
ROLE                           PRIVILEGE                                ADMIN_OPTION
------------------------------ ---------------------------------------- ------------
SCHEDULER_ADMIN                MANAGE SCHEDULER                         YES
 
SQL>

 

 关于权限角色的查询，引用如下：

http://bbs.csdn.net/topics/350162742

 

--1.查看所有用户：
  select * from dba_users;
  select * from all_users;
  select * from user_users;
 
--2.查看用户或角色系统权限(直接赋值给用户或角色的系统权限)：
  select * from dba_sys_privs;
  select * from user_sys_privs;
 
--3.查看角色(只能查看登陆用户拥有的角色)所包含的权限
 
sql>select * from role_sys_privs;
 
--4.查看用户对象权限：
  select * from dba_tab_privs;
  select * from all_tab_privs;
  select * from user_tab_privs;
 
--5.查看所有角色：
  select * from dba_roles;
 
--6.查看用户或角色所拥有的角色：
  select * from dba_role_privs;
  select * from user_role_privs;
 
--7.查看哪些用户有sysdba或sysoper系统权限(查询时需要相应权限)
 
select * from V$PWFILE_USERS
 
--注意：
--1、以下语句可以查看Oracle提供的系统权限
 
select name from sys.system_privilege_map
 
--2、查看一个用户的所有系统权限(包含角色的系统权限)
 
SELECT privilege
  FROM dba_sys_privs
 WHERE grantee = 'DATAUSER'
UNION
SELECT privilege
  FROM dba_sys_privs
 WHERE grantee IN (SELECT granted_role FROM dba_role_privs WHERE grantee = 'DATAUSER');
