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>
5、查看alert中的内容 SQL> select * from alert where rownum<20; LOG -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Wed Feb 27 11:05:11 2013 Starting ORACLE instance (normal) Cannot determine all dependent dynamic libraries for /proc/self/exe Unable to find dynamic library libocr10.so in search paths RPATH = /ade/aime1_build2101/oracle/has/lib/:/ade/aime1_build2101/oracle/lib/:/ade/aime1_build2101/oracle/has/lib/: LD_LIBRARY_PATH is not set!

6、看看数据库有哪些 可爱的ORA- 错误吧 SQL> select * from alert where log like '%ORA-%'; LOG -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ORA-959 signalled during: alter database default tablespace users... ORA-959 signalled during: drop tablespace uses... ORA-12919 signalled during: drop tablespace users... ORA-1549 signalled during: drop tablespace users...
