奔走青春的日子

青春是一部诰命的史书 有健壮的马匹和驼队 有长风嘶啸 ;青春推开窗 有流淌不尽的清流 恣意几曲酒醉的探戈 ;青春该有一只洞箫 去冻开白雪皑皑的梅花的骨头 ;青春解读千万种风情 而后奏唱出桃红柳绿 蜂鸣蝶咏。

runstats脚本

下面是thoms kyte的runstats脚本,为了便于运行先付权给user

grant select on sys.v_$timer to user1;

grant select on v_$mystat to  user1;

grant select on sys.v_$statname to user1;

grant select on sys.v_$latch to user1;

脚本:

 

create or replace view stats
as
select 'STAT..' || a.name name, b.value
from v$statname a, v$mystat b
where a.statistic# = b.statistic#
union all
select 'LATCH.' || name, gets
from v$latch;

create global temporary table run_stats
( runid varchar2(15),
name varchar2(80),
value int
)on commit preserve rows;

create or replace package runstats
as
procedure rs_start;
procedure rs_middle;
procedure rs_stop( p_difference_threshold in number default 0);
end;
/

create or replace package body runstats
as
g_start number;
g_run1 number;
g_run2 number;
procedure rs_start
is
begin
delete from run_stats;
insert into run_stats
select 'before', stats.* from stats;
g_start := dbms_utility.get_time;

相思意

                                         卜算子
                                                 ——李之仪
                                     我住长江头,
                                     君住长江尾。
                                  日日思君不见君,
                                     共饮长江水。
                                     此水几时休,
                                     此恨何时已。 
                                  只愿君心似我心,
                                     不负相思意。
     冬季总是让人憔悴,看着大风刮过卷起我无数的忧愁。
有一首邓丽君唱的曲子《相思意》,细细听是宋代李之仪的《卜算子》,
摘录下来。,“我住江之头,君住江之尾”,这天涯相隔距离是那样的遥远,
然而时空是阻隔不了思念,朝也盼来暮也思,浓浓的相思跃然纸上,唯有眼前长江水,
也只能从“共饮长江水”中得到慰藉。思念是如此的深。
朝朝代代有无数的悲欢离合,直到今日我们也如此。为了工作生存我们必须外出拼搏,
虽然有电话可是还是不能团聚。每当我在厦门走出飞机的那刻都是那么的激动,家的感觉油然而生。
不知我的朋友们,你们是否在正在挂念着你的另一半呢?
这里的“此水几时休, 此恨何时已”也是一样的痴情,但另人感叹的是,
诗歌哀而不伤用长江水把彼此的思念连接在一起,斗转星移,不会改变。
经历了许多的人生际遇,现在再读它,再看世的变幻悲欢,难免也感叹啊。

又一年冬季

      又是一年的冬季,天变凉了。
      厦门的天开始刮风,人都穿上厚衣服。
      已经习惯了饭后到花园散步,今天突然意识到已经是冬季了。
      回想一下往年的冬季我都在干什么?
      中学时候忙读书,冬季印象最深的是运动会,那时候我是多么的瘦阿,哈哈。
      大学时候忙恋爱,冬季日子都是被浓浓的爱情滋味所包围。
      工作时候忙事业,冬季的日子基本是在北京度过,印象最多的就是熬夜奋战突击问题。
      今年,工作以后第一次在厦门过,突然感觉不到冬季的存在。今天晚霞很美,火一样的热情。
      但愿这个冬季能给我不一样的感受。也祝愿我所有的朋友们一切都好。

时光小记

      从桂林回来一直想找时间把一些好看的照片放上来,可惜马上就被项目给占有了,今天好不容易抽出空间,竟然发现照片在存储卡里面,只好传了几张。桂林好山好水好歌,游玩四天,流连忘返。一晃有快过去1月了,新项目给我很多机会和挑战,也逐步使我有了一些对人对事的看法,项目估计要忙到年后三月,争取有时间多思考。天一下变凉了许多,本还有对深秋的惆怅瞬间变成了过冬的准备,想想也是,多愁善感何不比直来面对来的复杂,生活的压力下,还是不要愁了:)
