当前第2页返回上一页

　　 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 < 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.
