日志项目集成：

项目说明：多台Web服务用用LVS进行负载均衡，并且多台Web服务器的apache日志由独立一台日志服务器来记录到syslog日志中。（这里主要介绍如何使用syslog日志服务远程管理apache日志）

clip_image001

∵apache本身有一套日志系统，记录在/var/log/httpd/中。现在想用独立的一台syslog日志服务器记录apache日志信息。

∴用“管道”：| logger

在各台Web服务器设置：

⑴ 上加-r参数，开启远程日志管理。

[root@vm5: ~]#vim /etc/sysconfig/syslog

—————————————————–前略———————————————————–

SYSLOGD_OPTIONS=”-m 0 -r -x” 注：-m：MAC -r：开启远程日志 -x：不DNS

—————————————————–后略———————————————————–

⑵ 在apache的配置文件/etc/httpd/conf/httpd.conf中，增加| logger 。

[root@vm5: ~]#vim /etc/httpd/conf/httpd.conf

—————————————————–前略———————————————————–

# For a single logfile with access, agent, and referer information

# (Combined Logfile Format), use the following directive:

#

CustomLog logs/access_log combined

CustomLog “| logger -p info” combined

—————————————————–后略———————————————————–

此时，就可以在独立的syslog日志服务器上，查看到各台Web服务器的日志了！！！

]]> http://tq.freehostia.com.freehostia.com/2009/08/wp-syntax.html/feed 0 Oracle关于时间/日期的操作 http://tq.freehostia.com.freehostia.com/2009/08/oracle-time-or-timestamp.html http://tq.freehostia.com.freehostia.com/2009/08/oracle-time-or-timestamp.html#comments Tue, 18 Aug 2009 08:01:50 +0000 TQ http://tq.freehostia.com.freehostia.com/2009/08/oracle-time-or-timestamp.html 1.日期时间间隔操作

当前时间减去7分钟的时间 

select  sysdate,sysdate - interval '7' MINUTE  from dual;

当前时间减去7小时的时间

当前时间减去7天的时间 

1

SELECT  sysdate - interval '7' day  FROM dual ;

当前时间减去7月的时间 

select  sysdate,sysdate - interval '7' month from dual ;

当前时间减去7年的时间 

select  sysdate,sysdate - interval '7' year   from dual ;

时间间隔乘以一个数字

select  sysdate,sysdate – 8 *interval ‘2′ hour   from dual;

2.日期到字符操作

select  sysdate,to_char(sysdate,’yyyy-mm-dd hh24:mi:ss’)  from dual ;

select  sysdate,to_char(sysdate,'yyyy-mm-dd hh:mi:ss')  from dual ; 

select  sysdate,to_char(sysdate,'yyyy-ddd hh:mi:ss')  from dual ; 

select  sysdate,to_char(sysdate,'yyyy-mm iw-d hh:mi:ss')  from dual ;

   参考oracle的相关关文档(ORACLE901DOC/SERVER.901/A90125/SQL_ELEMENTS4.HTM#48515)

3. 字符到日期操作

select  to_date(’2003-10-17 21:15:37′,’yyyy-mm-dd hh24:mi:ss’) from dual

具体用法和上面的to_char差不多。

4. trunk/ ROUND函数的使用

select  trunc(sysdate ,’YEAR’)  from dual

select  trunc(sysdate )  from dual

select  to_char(trunc(sysdate ,’YYYY’),’YYYY’)  from  dual

5.oracle有毫秒级的数据类型

–返回当前时间 年月日小时分秒毫秒

select to_char(current_timestamp(5),’DD-MON-YYYY HH24:MI:SSxFF’) from dual;

–返回当前 时间的秒毫秒，可以指定秒后面的精度(最大=9)

select to_char(current_timestamp(9),’MI:SSxFF’) from dual;

6.计算程序运行的时间(ms)

declare

    type rc is ref cursor;

    l_rc rc;

    l_dummy all_objects.object_name%type;

    l_start number default dbms_utility.get_time;

begin

    for  I  in 1 .. 1000

    loop

        open l_rc for

          ’select object_name  from all_objects ‘||

‘where object_id = ‘ || i;

        fetch l_rc into l_dummy;

        close l_rc;

    end loop;

    dbms_output.put_line

    ( round( (dbms_utility.get_time-l_start)/100, 2 ) ||

      ‘ seconds…’ );

end;
