1、檢視作業系統版本
sql> select * from v$version;
banner
oracle database 10g enterprise edition release 10.2.0.1.0 - prod
pl/sql release 10.2.0.1.0 - production
core 10.2.0.1.0 production
tns for linux: version 10.2.0.1.0 - production
nlsrtl version 10.2.0.1.0 - production
sql>
2、檢視預警日誌檔案(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、建立目錄alert
注意：directory不是實體，只是乙個指向，指向os中乙個路徑
sql> create or replace directory alert as '/u01/oracle/admin/bdump';
directory created.
sql>
4、建立外部表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、檢視alert中的內容
sql> select * from alert where rownum<20;
logwed feb 27 11:05:11 2013

6、看看資料庫有哪些 可愛的ora- 錯誤吧
sql> select * from alert where log like '%ora-%';
