时间:2019-11-20 17:01     来源/作者:oracle教程网

1、查看操作系统版本 
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、查看预警日志文件(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; 
LOG 
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

6、看看数据库有哪些 可爱的ORA- 错误吧
