忙得...


上午,从家到民生西单,35大洋;然后到民生安定门,35大洋;下午忽然说得马上去上海,所以今天晚上去上海的火车票是肯定废了; 金融街找渣滓同学要火车票、西直门退票然后回家,100大洋;晚上要去洋桥找zhoubo同学值夜班,又得100多大洋;赫赫,路上的一天啊:)

本来想改成明早去上海,但计划是永远赶不上变化的। 明天还得去怀柔:(

好像有三个多星期没有去过公司了。改天有时间去好好坐一天,哈哈。

看大家msn签名,yunyi不再“忙得像条狗了”,不过某同学竟然忙得变成猪了,哈哈,忙成啥不好?!

db2 HA fallover problem

DB2 HA on two AIX server A and B, HACMP take over test is OK.
but when we issue"halt -q" on on server A, B can take over all the resource of A but it is very slow when it come to "db2start", 16nodes start cost 30 minutes।
some problems about networking is reported:
1. the service ip of B is moved to another interface. also the service ip of A is moved to the same interface.
2। "Interface 192.168.7.3 has failed on node PDBA","Interface 192.168.7.3 is now available on node PDBA". 7.3 is bootip of B.

I have to leave on tomorrow, and suggest 800 support। wait for further progress.

这种想法就是错误的
不是谁养谁
是如何找到自己的社会角色
爬山爬的越高,你的眼睛只会网上看站在更高处的人
等你下山了,你才发现,不管爬多高,都是娱乐而已
爬的低的女孩可能更容易和攀到顶峰的男生一起下山
所以师太们发现,山顶没有人
她们看到的只有神仙

T60*分身无术



今天看tanzhi同学拿了新的T60p,心里也权衡了一下自己是不是愿意花自己的米买一台. 结论是看看有没有替代品:)

T60看起来有点傻乎乎的,感觉式样和外壳的材质比T4*系列都有下降. 如果说T4*是稳重中透着睿智,那么T60就有点做稳重状但决无睿智可言了. 虽然偶一面的印象说明不了大问题,不过心里想如果自己买本的话是不是应该去看看hp的nc6000?

中午打了一个比较长的电话,短电话很多,然后就觉得不舒服. 也许正好是下午困了的原因,反正头疼. 想怕不是被辐射坏了吧. 以后还是得带耳机.

最近三个周末了都没有休息过,中间更不用说,有点招架不来了। 人要是在北京呢,还可以东奔西跑的想办法,可就不能出门!最近出差家里就没有消停过।有时候想抽自己,别人找来的时候总是尽量挤时间出来,还安排的紧紧的,真是找不自在。整天很累,想听点安慰的话,结果得到的是冷言冷语:你别以为你现在做的怎么样了,要是老板真当你重要早就如何如何了云云,心里就一下子沉下来,象被泼了冷水,想分辨什么但又不知道从哪里说起.干活的时候客户很buyin的感觉是很好的,但有时候又觉得回报了了,这感觉实在是有些灰心.


看到新东西,想到新办法或者更好的办法现在就想能不能bundle成一个solution在客户中推广. 觉得team里面应该有一个小组,研究我们可以提供怎样的solution,怎样更优. 作为一个onsite support team,如果只是单纯的做product support,而且也不可能做到产品internal去,这就缺少长久的value.

从个人角度,在最初的几年,team里面能接受的锻炼是非常有价值的. 自己的经历自己了解,清晰的过程,也是在不断的犯错误和改正错误, 从开始接受并传播某种观点到思考怀疑试图改进某些观点.

今天客户问我们是不是有专门的consutant设置?因为他觉得我现在做的就是这样的事情. 哦,可惜不是.在这里太多次都是匆匆来匆匆去,前后一两个小时,动嘴远多于动手,这个感觉其实很好. 觉得实在是受益于这两年高强度的训练和花了不少力气研究的os和storage,这力气花的很值:)

最后,忍不住发下牢骚拉,刚刚填pbc还是小小band6,真郁闷!!!

post-relational database

Actually,I know it from one of google adsence ADs and find this one, "Caché", interesting। say, google ADs let me know more about the database tools market:)

  1. A powerful, multidimensional transaction engine that includes the ability to create distributed databases।
  2. Unified data architecture uniting the power of objects with high performance SQL।
  3. A suite of technologies and tools that provide rapid development for database and web applications.
  4. Native, object-based XML and Web Services support. For more information on Caché's XML features refer to Using XML with Caché.
  5. Automatic interoperability via Java, EJB, JDBC, ActiveX, .net, C++, ODBC, XML, SOAP, and more.
Seems to be a powerful database, has a lot advantages over existing widely used DBMSes। But, I suspect the performence, I don't think it can deliver a stronger performance than existing DBMSes. It claims that it has a lot of customers over the world...

There's a need, there's a new idea, then there's the money. trust it.

尘缘与亵渎

亵渎是第一部让我一直跟下去的网络小说,大作,绝对的大作। 不过开始阶段的行文太黑暗了,以致于好几次都看一点然后就放弃了। 直到06年春节在家实在无聊了才又拿出来,然后就不再释卷了।

亵渎 http://www.booksky.biz/Directory.aspx?BookID=1952&SortID=5534

尘缘是烟雨江南继亵渎之后的又一大作, 行文风格和亵渎最后阶段的转折一脉相承। 文字更优美,措辞也更考究,是网络小说中难得的精品। 不过也因为过于讲究,也就缺了亵渎的流畅,不够痛快淋漓।

另外,烟大似乎总是喜欢把主角在开始阶段弄得让大家不爽...太卑鄙了太无耻了!

顺便说一下,linyi老大自称也曾经叫过烟雨江南... 这个您老是肯定抢不回来了:)

about DB2 HACMP/HADR/CAS VS. Oracle RAC

I like what Oracle RAC delivers, it's very appealing। ,But,You know, everything has its shortcomings, though sounds perfect।

"RAC provides transparent application failover for reads (if you use Transparent Application Failover and their thick JDBC client), but not for writes."

DB2 CAS can avoid this by serving with buffering with SQL in CAS server and utilize two or more same databases... I know DB2 CAS will be very new to the majority, but it is. I think it's the real one(from IBM) can be compete to Oracle RAC. more, since CAS is seperated from databases, so it can be configured in various way. It also can support websphere HA.

interesting SQL, consolidate time period

it's post on usenet, intersting problem, let think about it. Siege had given the answers.

Given a very simple table of events, with
their durations, I want to consolidate time periods for an event that
(1) touch each other or (2) overlap each other.

CREATE TABLE Events
(event_id VARCHAR(25) NOT NULL,
start_date DATE NOT NULL,
end_date DATE NOT NULL,
CHECK (start_date <= end_date),
PRIMARY KEY (event_id, start_date, end_date));

INSERT INTO Events
VALUES ('Pie Eating', '2009-01-01', '2009-01-02'),
('Pie Eating', '2009-01-03', '2009-01-05'),
('Pie Eating', '2009-01-04', '2009-01-07'),
('Pie Eating', '2009-02-01', '2009-02-07');

The goal is to reduce these three rows into fewer rows that show how
many days we were eating pies.

('Pie Eating', '2009-01-01', '2009-01-07')

The first and second rows in the INSERT INTO statement touch each
other and can be replaced with:

('Pie Eating', '2009-01-01', '2009-01-05')

The third row will overlap with this new row and can be consolidated
with it, as shown before. However, the fourth row has data that
occurs a month after the first three and it is disjoint from all the
other rows.

db2 prior to v8.2, gcc @ AIX

Just with ZhaoYong, configure gcc compiler for DB2 on AIX 5L।

we found the article in comments is very useful, but I just cannot find who the author is...
