  采取贷款或分期付款购买住房的,资料同上,如本人无购房合同原件,可用与银行签订的借款合同原件及复印件代替,同时交购房合同复印件。办理支取时,购房人是配偶一方的需持结婚证原件及复印件,并且需由购房人先行支取,并提供其支取记录单复印件。

好文章
大的数据中心有成千上万台服务器,服务器之间大都用TCP来协作并传输数据,最终为用户提供服务。那数据中心的TCP工作得如何呢? 斯坦福大学和微软的两人对Bing服务的6000多台服务器集群在TCP方面的数据进行研究,用的数据是一个月的日志,包括应用、套接字级别和包级别的日志,压缩完后大概是150T的数据。老外真是牛!

一、发现的问题
1、突发的丢包现象
2、部分包传输时延大,90%的传输RTT值小于1毫秒,10%的RTT值在1到15毫秒之间

  • Sending data

    The thread is reading and processing rows for a SELECT statement, and sending data to the client. Because operations occurring during this this state tend to perform large amounts of disk access (reads), it is often the longest-running state over the lifetime of a given query.

最近,老是磁盘error,而自己确没有迅速的定位,实在是感到杯具,看到同事们MegaCli查看raid及磁盘错误信息,我这里粘贴下网上别人 用的命令,方便自己查阅(另dmesg:显示开机信息,dmidecode,硬件信息)

MegaCli用起来还是很简单的。摘抄一些比较常用的参数如下:

显示适配器个数: MegaCli -adpCount
显示适配器时间: MegaCli -AdpGetTime –aALL
显示所有适配器信息: MegaCli -AdpAllInfo -aAll
显示所有逻辑磁盘组信息: MegaCli -LDInfo -LALL -aAll
显示所有的物理信息: MegaCli -PDList -aAll

查看充电状态: MegaCli -AdpBbuCmd -GetBbuStatus -aALL |grep ‘Charger Status’
显示BBU(后备电池)状态信息: MegaCli -AdpBbuCmd -GetBbuStatus -aALL
显示BBU容量信息: MegaCli -AdpBbuCmd -GetBbuCapacityInfo -aALL
显示BBU设计参数: MegaCli -AdpBbuCmd -GetBbuDesignInfo -aALL
显示当前BBU属性: MegaCli -AdpBbuCmd -GetBbuProperties -aALL

LVM1 has read-only snapshots. Read-only snapshots work by creating an exception table, which is used to keep track of which blocks have been changed. If a block is to be changed on the origin, it is first copied to the snapshot, marked as copied in the exception table, and then the new data is written to the original volume.

In LVM2, snapshots are read/write by default. Read/write snapshots work like read-only snapshots, with the additional feature that if data is written to the snapshot, that block is marked in the exception table as used, and never gets copied from the original volume. This opens up many new possibilities that were not possible with LVM1's read-only snapshots. One example is to snapshot a volume, mount the snapshot, and try an experimental program that change files on that volume. If you don't like what it did, you can unmount the snapshot, remove it, and mount the original filesystem in its place. It is also useful for creating volumes for use wit

From DBA's standpoint, you have a couple of choices for storage allocation.
- Storing all files on SSD, not using HDD at all
- Storing all files on HDD, not using SSD at all
- Using SSD and HDD altogether (some files on SSD, others on HDD).

Which is the best approach? My favorite approach is storing tables on SSD, storing Redo Log files, Binary Log files, and SYSTEM-tablespace(ibdata) on HDD. I describe a detailed reason and some DBT-2 benchmarking results below.

On HDD, there is a huge difference between random writes and sequential writes. Sequential writes is very fast on HDD with write cache. On the other hand, on SSD, there is not so much difference between random writes and sequential writes. Though performance highly depends on SSD drives themselves, you probably notice that sequential write performance is not so different between HDD and SSD (or even faster on HDD). Since HDD has a longer history and is cheaper than SSD, currently the

喜欢Mysql,不仅仅是因为他简单的使用,更深一层次的是因为他的开源、他的插入式引擎及更优秀的plugin!从队列式存储引擎Q4M(http://q4m.github.com/)到memcache 的UDF(http://hi.baidu.com/ytjwt/blog/item/5fc8303f226c542f71cf6c3c.html) 到本文要说到的NoSQL for MySQL,去年的某一天,一朋友跟我说,nosql性能有多好多好时,我说,如果提取像k/v形式的数据,假设:用主键查询一个数据,你觉得性能会怎样 呢?其实当时我也知道,肯定是比不过memcache之类的cache,因为,mysql有一系列的认证,一系列的语法、词法分析!

前段一个偶然的时间里,下载percona-server突然发现一个名叫HandlerSocket的东东,一时好奇,google一把,发现这不就是我一直想要的在mysql里实现nosql的东西吗?兴奋之余,也动手安装及使用了一把,下面把我的步骤列出来!

主要参考:http://whitesock.javaeye.com/blog/811339

1:安装

HandlerSocket老简单了,只需要5.1版本以上的s
