根据 dba_errors 制定 数据库报警邮件

一.dba_errors表

官网对这个表的说明如下：

ALL_ERRORS：describes the current errors on the stored objects accessible to the current user.

DBA_ERRORS：describes the current errors on all stored objects in the database.

USER_ERRORS：describes the current errors on the stored objects owned by the current user.This view does not display the OWNER column.

示例：

SQL> select owner,name,type,text,attribute from dba_errors;

OWNERNAMETYPETEXTATTRIBUTE

---------- ------------------------- ------------ -------------------------------------------------- ---------

SYSPROC_ALARM_KC_SCBPROCEDUREPL/SQL: ORA-00942: table or view does not existERROR

SYSPROC_ALARM_KC_SCBPROCEDUREPL/SQL: SQL Statement ignoredERROR

SYSPROC_ALARM_KC_SCBPROCEDUREPLS-00201: identifier 'JOBLOG.WRITELOG' must be de ERROR

SYSPROC_ALARM_KC_SCBPROCEDUREPL/SQL: Statement ignoredERROR

SYSPROC_ALARM_KC_SCBPROCEDUREPLS-00201: identifier 'RUNLOG.ERRORLOG' must be de ERROR

SYSPROC_ALARM_KC_SCBPROCEDUREPL/SQL: Statement ignoredERROR

从这个表里面，我们可以看到数据库当前存在的错误，这些错误信息包含对象名称，类型，所有者，错误类型和错误原因。

如果该表里有这些错误，就可以调用Oracle的发送邮件的存储过程，将这些信息发送到相关邮箱或者移动的139邮箱，该邮箱可以直接将邮件发送到手机。这样就可以起到一个及时通知的作用。

发送邮件的存储过程参考Blog：

不同用户的错误，发送到相关的责任人，当然DBA肯定都要收到。

三.使用Scheduler Job部署

Oracle 10g Scheduler特性

http://blog.youkuaiyun.com/xujinyang/article/details/6830222

3.1创建Job：

BEGIN

DBMS_SCHEDULER.CREATE_JOB (

job_name => 'Jobgetsenterrlog',

job_type => 'STORED_PROCEDURE',

job_action =>'GETSENTERRLOG',--调用的过程名称

start_date => sysdate,

repeat_interval => 'FREQ=MINUTELY;INTERVAL=1');--每个一分钟执行一次

END;

/

关于这些参数的说明，参考上面的链接。

注意：

JOB虽然成功创建了，但却并未执行.因为ENABLED参数当不显式指定时，该参数的默认值为false。

3.2启用Job

exec dbms_scheduler.enable('Jobgetsenterrlog');

3.3停止Job

exec dbms_scheduler.disable(' Jobgetsenterrlog');
