ORACLE 报警日志如何查看？第1/2页
问题描述：
目得：首先了解什么是外部表，与其它表的区别，建立一个简单的外部表(主要看操作过程)，最后我们用外部表查看ORACLE报警日志
答
3.测试
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') ); |
首先查看能否查到alert_db2.log的内容
|
SQL> select * from alert_log where rownum < 10; TEXT -------------------------------------------------------------------------------- Thu Jun 11 00:51:46 2009 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/:/a de/aime1_build2101/oracle/has/lib/: LD_LIBRARY_PATH is not set! The default library directories are /lib and /usr/lib Unable to find dynamic library libocrb10.so in search paths Unable to find dynamic library libocrutl10.so in search paths 9 rows selected. |
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 .dbf' ORA-27037: unable to obtain file status ORA-205 signalled during: ALTER DATABASE MOUNT... ORA-00301: error in adding log file '/home/oracle/oracle/oradata/testdb/redo01.l og' - file cannot be created ORA-27040: file create error ORA-1501 signalled during: CREATE DATABASE db2 ORA-00200: control file could not be created TEXT -------------------------------------------------------------------------------- ORA-00202: control file: '/oracle/u01/app/oracle/product/10.2.0/db2/dbs/cntrldb2 .dbf' ORA-27038: created file already exists ORA-1501 signalled during: CREATE DATABASE db2 ORA-00200: control file could not be created ORA-00202: control file: '/oracle/u01/app/oracle/product/10.2.0/db2/dbs/cntrldb2 .dbf' ORA-27038: created file already exists ORA-1501 signalled during: CREATE DATABASE db2 |
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.
