2. 使用外部表查看oracle报警日志
由于在上面实验中已建立了一个用户,并赋相应的权限,而且也有了OS文件(即报警文件alert_SID.log),所以在此直接建立目录对象并建立外部表就可以了。
1.建立目录对象
SQL> conn test / 123
Connected.
SQL> create directory bdump as '/oracle/u01/app/oracle/admin/db2/bdump';
Directory created.
2.建立外部表
SQL> create table alert_log(
text varchar2(400)
)organization external
(type oracle_loader
default directory bdump
access parameters
(records delimited by newline
)location('alert_db2.log')
);3.测试
首先查看能否查到alert_db2.log的内容
SQL> select * from alert_log where rownum
TEXT
--------------------------------------------------------------------------------

Starting ORACLE instance (normal)
Cannot determine all dependent dynamic libraries for /proc/self/exe

测试成功
然后我们测试查报警信息'ORA-%'
SQL> select * from alert_log where text like 'ORA-%';
TEXT
--------------------------------------------------------------------------------
ORA-00202: control file: '/oracle/u01/app/oracle/product/10.2.0/db2/dbs/cntrldb2

测试成功,
可见我们可以使用外部表来方便的查看ORACLE的报警信息.
