Oracle监控系统错误日志过程

--创建临时表用来存放系统错误信息
create table superflow(cust_id number(10),cust_name varchar2(100),d varchar(50),error_info varchar2(500),client_ip varchar2(50),protocol varchar2(100),t number(20),sj date) tablespace db_data;
   
 --drop table superflow
 
--创建数据写入路径 
create directory db_dir as '/home/Oracle';

--把目录授权给用户
grant read,write on directory db_dir to db;

监控系统错误日志 
过程完成任务有
 把抽取出来错误日志插入到superflow
错误日志会写入操作系统/home/oracle/sql.txt文件下面
create or replace procedure pro_superflow as
