2、查看预警日志网站网站文件（alert_sid.log）的位置
SQL> show parameter dump
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
background_core_dump string partial
background_dump_dest string /u01/oracle/admin/bdump
core_dump_dest string /u01/oracle/admin/cdump
max_dump_file_size string 10240
shadow_core_dump string partial
user_dump_dest string /u01/oracle/admin/udump
3、创建目录alert
注意：directory不是实体，只是一个指向，指向os中一个路径
SQL> create or replace directory alert as '/u01/oracle/admin/bdump';
Directory created.
SQL>
4、创建外部表alert
SQL> create table alert
1 (log varchar2(1000))
2 organization external
3 (type oracle_loader
4 default directory alert
5 access parameters
6 (records delimited by newline)
7 location ('alert_PROD.log'))
8 reject limit unlimited;
Table created.
5、查看alert中的内容
SQL> select * from alert where rownum<20;
