[原]找出Oracle alert文件中的ORA错误
位于$ORACLE_BASE/[SID]/bdump/的alert_[SID].log文件虽然不影响Oracle的正常运行,但是对于Oracle DBA 来说是一个定位问题的重要线索。今天周大师提出一个需求,通常来说alert文件比较大,里面记录了很多有用的信息,但是通常来说比较注重看ORA-XXXX的错误信息,如果使用Linux的grep(grep ORA < alert_[sid].log)命令虽然可以轻易地找出所有ORA-XXXX的错误,缺丢失了“时间”这个重要的信息。于是乎,我用Perl写了个小程序,用于同时获得这两个重要的信息。使用Perl进行编写的原因是:
1。Linux环境下基本上都有Perl的运行环境。
2。Perl处理文本实在太爽了。
首先,看看alert文件内容的大概样子:
... ....

你看到时间和错误信息了吗 :) 。以下是我写的perl小程序:
#! /usr/bin/perl -w # alert_ora_finder.pl use strict; my ($argv) = @ARGV; if ( $argv && ! -e $argv ) { print ' Welcome To Use alert_ora_finder (Oracle Alert File ORA Error Finder) Powered By killkill $ cat alert_[sid].log | alert_ora_finder.pl $ tail -f alert_[sid].log | alert_ora_finder.pl $ alert_ora_finder.pl alert_[sid].log '; exit; } my $cap_regex = '^(\w+ \w+ \d{2} \d{2}:\d{2}:\d{2} \d{4})|(ORA-\d+:.+)$'; my $tmp_date = ""; my $line_counter = 0; while ( <> ) { $line_counter++; if( m/$cap_regex/oi ) { if ($1) { $tmp_date = $1; next; } print "$line_counter | $tmp_date | $2 \n" if ($2); } }
输入如下:
[root@oracle01 perl]# ./alert_ora_finder.pl /u01/app/oracle/admin/ora10g/bdump/alert_ora10g.log 230 | Fri Aug 28 22:47:27 2009 | ORA-00313: open failed for members of log group 1 of thread 1 231 | Fri Aug 28 22:47:27 2009 | ORA-00312: online log 1 thread 1: '/u01/app/oracle/oradata/ora10g/redo01.log' 232 | Fri Aug 28 22:47:27 2009 | ORA-27037: unable to obtain file status 237 | Fri Aug 28 22:47:28 2009 | ORA-00313: open failed for members of log group 2 of thread 1 238 | Fri Aug 28 22:47:28 2009 | ORA-00312: online log 2 thread 1: '/u01/app/oracle/oradata/ora10g/redo02.log' 239 | Fri Aug 28 22:47:28 2009 | ORA-27037: unable to obtain file status 244 | Fri Aug 28 22:47:29 2009 | ORA-00313: open failed for members of log group 3 of thread 1 245 | Fri Aug 28 22:47:29 2009 | ORA-00312: online log 3 thread 1: '/u01/app/oracle/oradata/ora10g/redo03.log' 246 | Fri Aug 28 22:47:29 2009 | ORA-27037: unable to obtain file status 1411 | Wed Sep 23 23:18:07 2009 | ORA-1653: unable to extend table GAME.MANY_OBJECTS by 128 in tablespace GAME 1413 | Wed Sep 23 23:18:07 2009 | ORA-1653: unable to extend table GAME.MANY_OBJECTS by 128 in tablespace GAME 1415 | Wed Sep 23 23:18:07 2009 | ORA-1653: unable to extend table GAME.MANY_OBJECTS by 128 in tablespace GAME 1469 | Wed Sep 23 23:18:07 2009 | ORA-1652: unable to extend temp segment by 128 in tablespace GAME
其中,最左边的是输入端的行号,第二列是时间,第三列就是ORA-XXXX的错误信息了。
