硬盘物理坏道修复
对于个人电脑用户来说,硬盘的更新频率一般没有CPU 或显示卡那么快--即使要买新硬盘,老硬盘也要挂在机箱里发挥余热,所以人们最不愿意看到硬盘出故障,尤其是当硬盘中保存了珍贵的数据资料时。
硬盘属逻辑损坏倒也罢了,大不了重装软件,但物理损坏呢?其实只要情况不是特别严重,用一些方法处理,一般也能解决问题。
首先来看看硬盘有了物理损伤,也就是有了坏道后有哪些现象:1.读取某个文件或运行某个软件时经常出错,或者需要经过很长时间才能操作成功,其间硬盘不断读盘并发出刺耳的杂音,这种现象意味着硬盘上载有数据的某些扇区已坏。
2.开机时系统不能通过硬盘引导,软盘启动后可以转到硬盘盘符,但无法进入,用SYS命令传导系统也不能成功。
这种情况比较严重,因为很有可能是硬盘的引导扇区出了问题。
3.正常使用计算机时频繁无故出现蓝屏。
对于前面3种情况,我们一般都有办法作或多或少地补救。
以下提供了几种方法来对硬盘的坏道作修复,要注意的是,应该优先考虑排在前面的方法。
1.首先从最简单的方法入手。
在资源管理器中选择硬盘盘符,右击鼠标,在快捷菜单中选择“属性”,在“工具”项中对硬盘盘面作完全扫描处理,并且对可能出现的坏簇作自动修正。
对于以上第2种情况即不能进入 Windows的现象,则可以用Windows 的启动盘引导机器,然后在“A:>”提示符后键入“scand isk X:”来扫描硬盘,其中“X”是具体的硬盘盘符。
对于坏簇,程序会以黑底红字的“B”(bad)标出。
2.实际上,第1种方法往往不能奏效,因为Windows对“坏道”的自动修复很大程度上是对逻辑坏道而言,而不能自动修复物理坏道,所以有必要考虑对这些坏道作“冷处理”。
所谓“冷处理”就是在这些坏道上作标记,不去使用,惹不起还躲得起。
记住第1种方法中坏道的位置,然后把硬盘高级格式化,将有坏道的区域划成一个区,以后就不要在这个区上存取文件了。
要说明的是,不要为节约硬盘空间而把这个区划得过分“经济”,而应留有适当的余地,因为读取坏道周围的“好道”是不明智的--坏道具有蔓延性,如果动用与坏道靠得过分近的“好道”,那么过不了多久,硬盘上新的坏道又将出现。

实验：GPT与MBR磁盘互相转换
(▲转换前：MBR 磁盘下划分了 3 个主分区+1 个扩展分区)
使用 DG 转换时，提示：转换为 GPT 磁盘后，只有较新的系统才能正常读写（32 位 XP 不支 持 GPT） ；只有基于 EFI 的电脑系统才能从 GPT 磁盘正常启动；如果原 MBR 磁盘存在逻辑分 区，逻辑分区将被转换为主分区，且删除扩展分区 但是，转换可以进行下去，转换为 GPT 磁盘如下图：
GPT 与 MBR 磁盘互相转换 ——@南木嘉人
贴吧地址：/p/3756702943 实验前，你需要了解的： MBR 磁盘： 1) 默认不支持大于 2.2T 的分区 2) Windows 系统下最多支持 4 个主分区或 3 个主分区+1 个扩展分区（扩展分区必须划分 为逻辑分区才能使用，一个扩展分区可划分为多个逻辑分区） GPT 磁盘： 1) 支持大于 2.2T 的分区 2) Windows 系统下最多支持 128 个主分区 实验一：GPT 磁盘转换为 MBR 磁盘 情况 1：GPT 磁盘划分主分区数量大于 4 个
(▲在已有 4 个主分区的 MBR 磁盘上进行新分区操作时会提示：基本磁盘将被转换为动态 磁盘，转换为动态磁盘后，我们将无法从这个磁盘的任何分区（除了当前的启动分区）启 动已经安装的系统) 在这里，又出现两个陌生的名词：基本磁盘、动态磁盘 什么是基本磁盘和动态磁盘？ 微软官方说明如下： 基本磁盘和动态磁盘是 Windows 中的两种硬盘配置类型。大多数个人计算机都配置为基本 磁盘，该类型最易于管理。高级用户和 IT 专业人员可能使用动态磁盘，他们通常为提高 性能和可靠性而使用计算机中的多个硬盘来管理数据。 只有 Windows Vista Enterprise 和 Windows Vista Ultimate 版本支持动态磁盘。 更多了解请看这里：/zh-CN/windows-vista/What-are-basic-anddynamic-disks 从基本磁盘转换为动态磁盘后， 我们很有可能就无法正常启动系统了， 所以建议大家在这种 情况下，就不要强行转换为动态了。 如果真的要在已有 4 个主分区的 MBR 磁盘上新建分区，建议，你先将某一个主分区转换为 扩展分区，然后在这个扩展分区下创建新的逻辑分区。
安装_扫描枪安装使用教程_2011-12-2
扫描枪安装教程安装PC端的安装分二个部份：A)安装MS ActiveSync；B）配置通讯接口程序；C)配置与SAP 接口。
安装前首先要识别所安装的扫描枪，不同的扫描枪所使用的所使用的通信接口程序是不一样的，1-3代扫描枪使用的是玖龙程序scan,第4代扫描枪使用的接口程序是sapscan。
a.第一代扫描枪，东莞暂时只有六期国废成品库及外租仓库还有在使用，暂无图。
b. 第二代扫描枪c. 第三代扫描枪d. 第四代扫描枪注意从外观各枪上的英文识别扫描枪的型号，现在东莞基地用得比较多的是三代和四代。
1，在管理员权限下安装MSActiveSync（与通讯座连接驱动程序）这是微软提供的标准通讯工具，现在最新的版本是4.5 (Microsoft ActiveSync 4.5),东莞基地枪座连接驱动都用此版本，安装路径：\\Dgfile02\nd_files_5\东莞电脑部\02、技术支持区\30、扫描枪配置文件\扫描枪\Kyman-Net\PC\MS ActiveSync。
安装Microsoft ActiveSync 4.5过程中默认设置即可，直到安装完成后，重启电脑。
ActiveSync 与PC机的连接方式，可以是多样的，直通电缆（串口、USB）,机座+电缆（串口、USB ）;使用USB通讯比较方便。
安装完毕之后，将扫描器轻轻放在机座上，在任务栏上可以看到有个连接的图标，正常连接后图标激活。
使用MS ActiveSync进行连接的时候，要注意一点：打开连接设置：选择可以使用如下端口进行连接：串口COM1或USB连接。
同时，在终端上的控制面板—〉Setting—〉Control Panel—〉PC Connection，选择默认的同桌面电脑的连接方式为USB注：在ActiveSync 连接时，会询问是否建立合作伙伴关系，取消即可。
2，通讯接口程序只需要copy执行程序和相应的动态库即可。
A）由于该程序是利用 开发的，所以必须安装DotNetFrameWrok的环境（\\Dgfile02\nd_files_5\东莞电脑部\02、技术支持区\30、扫描枪配置文件\扫描枪\Kyman-Net\PC\DotNet Framework2.0），安装过程如下：1）、安装DotNetFrameWork 2.0。

InstallationPre-installation PrecautionsTake note of the following precautions before you install mother-board components or change any motherboard settings.1. Unplug the power cord from the wall socket before touching anycomponent. Failure to do so may cause severe damage to themotherboard, peripherals, and/or components.2. To avoid damaging the motherboard components due to staticelectricity, NEVER place your motherboard directly on the car-pet or the like. Also remember to use a grounded wrist strap ortouch a safety grounded object before you handle components.3. Hold components by the edges and do not touch the ICs.4. Whenever you uninstall any component, place it on a groundedantstatic pad or in the bag that comes with the component.5. When placing screws into the screw holes to secure the moth-erboard to the chassis, please do not over-tighten the screws!Doing so may damage the motherboard.2.1 CPU InstallationFor the installation of Intel 1155-Pin CPU,please follow the steps below.Before you insert the 1155-Pin CPU into the socket, please check if theCPU surface is unclean or if there is any bent pin on the socket. Do notforce to insert the CPU into the socket if above situation is found. Other-wise, the CPU will be seriously damaged.1155-Pin Socket OverviewEnglishStep 1. Open the socket:Step 1-1.

WinSock网络编程
WinSock 网络编程1. 概述80's 初，ARPA(美国国防部高级研究计划局)®加利福尼亚大学Berkeley 分校提供资金，®开发在UNIX 下实现TCP/IP 协议。
®为TCP/IP 开发了一个API –– Socket 接口（套接口）–– 俗称Bekeley 套接口模型。
90's 初，Microsoft 等公司®基于Bekeley 套接口模型®制定了Windows Sockets 规范(简称WinSock)®已是TCP/IP 网络的标准。
1993.1，v1.1 1995.5，v2.0，增加了QOS (网络服务质量控制)2. WinSock 模型提供TCP/IP 传输层的接口：①TCP(传输控制协议)提供虚电路和面向连接的数据流传输服务。
实现无差错无重复的顺序数据传输。
Z D r i v e r eo n.c o m .②UDP(用户数据报协议)提供无连接的数据报传输服务。
数据通过相互独立的报文进行传输，是无序的，并且不保证可靠、无差错。
3. WinSock DLL·WinSock 与操作系统的关系动态链接库·动态链接库： 16位版：WINSOCK.DLL 32位版：WSOCK32.DLL①DLL 装载WinSock 服务由动态连接库WinSock DLL 提供，它完成WinSock 的初始化任务，协商WinSock 的版本支持，并分配必要的资源。
在使用WinSock API 之前，必须调用：· int WSAStartup(WORD v, (LPWSADATA)&WD)其中：v ––– 指示应用程序对WinSock 版本的要求， 低字节为主版本号，高字节为副版本号。
例：v1.1 ® v=Ox0101, v2.0 ® v=Ox0002,WD ––返回WinSock 的实现信息。

精心整理物理standby 创建及维护一：服务器的环境配置双机DATAGUARD 配置，首先需要满足的基础环境就是两台独立运行且互访通畅的服务器。
参照即将作为主机的服务器配置，包括系统版本，内存配置，硬盘空间等软硬件参数对我们的备库服务器进行准备。
因为实际应用环境中，当主机出现不可挽回的故障后，备机将切换成为主机，承受主机等同的运行负荷。
二： 三：1、将1.11.223、配置oracle 1确保2创建适当的日志组，一般而言，standbyredo 日志文件组数要比primary 数据库的onlineredo 日志文件组数至少多一个。
Standbyredolog 的操作方式与onlineredolog 几乎一模一样，只不过在创建或删除时需要多指定一个standby 关键字，例如添加：SQL>alterdatabaseaddstandbylogfile('e:\lmis\STANDBYREDO01.LOG')size50M;删除也同样简单：SQL>alterdatabasedropstandbylogfilegroup4;验证standbyredolog 文件组是否成功创建SQL>SELECTGROUP#,THREAD#,SEQUENCE#,ARCHIVED,STATUSFROMV$STANDBY_LOG;4、创建primary数据库客户端初始化参数文件注：主要此处修改项较多，为了方便，我们首先创建并修改pfile，然后再通过pfile重建spfile，你当然也可以通过altersystemset命令直接修改spfile内容。
SQL>createpfile=’e:\lmis.ora’fromspfile;文件已创建。
下列参数为primary角色需添加的相关初始化参数：DB_UNIQUE_NAME=lmisprmLOG_ARCHIVE_CONFIG='DG_CONFIG=(lmisprm,lmisstd)'LOG_ARCHIVE_DEST_1='LOCATION=E:\lmis\archive以下参数为转为Standby)等数5确定-----selectFILE_NAMEfromdba_data_filesunionallselectTABLESPACE_NAME表空间,FILE_NAME数据文件,BYTES/1024/1024容量fromdba_temp_files)orderby表空间,数据文件表空间数据文件容量1 DATA E:\LMIS\DATAFILE\INF01.DBF 10242 INDX E:\LMIS\DATAFILE\INDX01.DBF 5123 LMIS E:\LMIS\DATAFILE\DATA01.DBF 20484 LMIS E:\LMIS\DATAFILE\DATA02.DBF 10245 LMIS E:\LMIS\DATAFILE\DATA03.DBF 10246 RBSG E:\LMIS\DATAFILE\RGSG01.DBF 20487 SYSAUX E:\LMIS\DATAFILE\SYSAUX01.DBF 10248 SYSTEM E:\LMIS\DATAFILE\SYSTEM01.DBF 10249 TEMP E:\LMIS\DATAFILE\TEMP01.DBF 102410 TOOLS E:\LMIS\DATAFILE\TOOLS01.DBF 1024-----联机重做日志文件SELECTgroup#,status,type,memberFROMV$LOGFILE;GROUP# STATUS TYPE MEMBER1 1 ONLINE E:\LMIS\LOGFILE\REDO01.LOG2 2 ONLINE E:\LMIS\LOGFILE\REDO02.LOG345676如果当前7通过1服2SQL>ALTERDATABASECREATESTANDBYCONTROLFILEAS'E:\LMIS\LOGFILE\CONTROL01.CTL';注意哟，控制文件通常需要有多份，你要么手工将上述文件复制几份，要么用命令多创建几个出来。
另外，创建完控制文件之后到standby数据库创建完成这段时间内，要保证primary数据库不再有结构性的变化(比如增加表空间等等)，不然primary和standby同步时会有问题。
3、创建初始化参数文件注：主要此处修改项较多，为了方便，我们首先创建并修改pfile，然后再通过pfile重建spfile，你当然也可以通过altersystemset命令直接修改spfile内容。
primary服务器执行SQL>createpfilefromspfile;文件已创建。
修改初始化参数文件中的参数（黑色加粗字体为需要修改的内容）DB_NAME=lmisDB_UNIQUE_NAME=lmisstdLOG_ARCHIVE_CONFIG='DG_CONFIG=(lmisprm,lmisstd)'CONTROL_FILES='E:\LMIS\LOGFILE\CONTROL01.CTL','E:\LMIS\LOGFILE\CONTROL02.CTL'DB_FILE_NAME_CONVERT='E:\lmis\datafile','E:\lmis\datafile'LOG_FILE_NAME_CONVERT='E:\lmis\logfile','E:\lmis\logfile'LOG_ARCHIVE_FORMAT='ARC%S_%R.%T'LOG_ARCHIVE_DEST_1='LOCATION=E:\lmis\archiveVALID_FOR=(ALL_LOGFILES,ALL_ROLES)DB_UNIQUE_NAME=lmisstd'数比如45、配置5.1通过5.1复位置是5．3配置Standby服务器和primary服务器都需要配置，一个监听，两个服务名(pri,std)，服务名要使用dedicate模式(SERVER=DEDICATED)。
5.4通过该pfile创建spfileSQL>createspfilefrompfile='D:\backup\initjsspdg.ora';文件已创建。
6、启动standby注意哟，咱们前面说过的，物理standby极少情况下可以以read-write模式打开，某些情况下可以以readonly模式打开，所以默认情况下，加载到mount状态即可,11G可以打开数据库。
SQL>STARTUP;7启动日志实时应用SQL>ALTERDATABASERECOVERMANAGEDSTANDBYDATABASEUSINGCURRENTLOGFILEDISCONNECTFROMSESSION;提示：disconnectfromsession子句并非必须，该子句用于指定启动完应用后自动退出到命令操作符前，如果不指定的话，当前session就会一直停留处理redo应用，如果想做其它操作，就只能新建一个连接。
8、查看同步情况8.1连接到primary数据库，查询已经存在的归档日志文件。
SQL>SELECTSEQUENCE#,FIRST_TIME,NEXT_TIMEFROMV$ARCHIVED_LOGORDERBYSEQUENCE#;8.2连接到standby数据库，查询已经存在的归档日志文件。
SQL>SELECTSEQUENCE#,FIRST_TIME,NEXT_TIME-8.3在8.4,在8.5在SEQUENCE#APP------------8YES9YES10YES11IN-MEMORY提示：APPLIED列值为YES或IN-MEMORY表明对应的归档日志已经被应用五：第二部分物理角色转换1，角色转换前的准备工作1.1检查各数据库的初始化参数，主要确认对不同角色相关的初始化参数都进行了正确的配置。
1.2确保可能成为primary数据库的standby服务器已经处于archivelog模式。
1.3确保standby数据库的临时文件存在并匹配primary数据库的临时文件。
2，物理standby的Switchover2.1检查是否支持switchover操作--primary数据库操作SQL>SELECTSWITCHOVER_STATUSFROMV$DATABASE;SWITCHOVER_STATUS-----------------TOSTANDBY1rowselected角色，2.2启动首先将2.32.4待原看看是，如否则检查其初始化参数文件中的设置，提示一下，比着原primary数据库的初始化参数改改。
2.5转换角色到primary--待转换standby数据库操作通过下列语句转换standby到primary角色：SQL>ALTERDATABASECOMMITTOSWITCHOVERTOPRIMARYWITHSESSIONSHUTDOWN;数据库已更改。
2.6完成转换，打开新的primary数据库SQL>alterdatabaseopen;数据库已更改。
注：如果数据库处于openread-only模式的话，需要先shutdown然后直接startup即可。
2.7备机上启动日志实时应用SQL>ALTERDATABASERECOVERMANAGEDSTANDBYDATABASEUSINGCURRENTLOGFILEDISCONNECTFROMSESSION;3，物理standby的failoverfailover之后，原primary数据库默认不再是dataguard配置的一部分。
如果待转换角色的standby处于maximumprotection或maximumavailability模式的话，归档日志应该是连续存在的，这种情况下你可以直接从第3步执行，否则建议你按照操作步骤从第1步开始执行。
一般情况下failover都是表示primary数据库瘫痪，最起码也是起不来了，因此这种类型的不影响3.119092这一步非常重要，3.2分别在必须primary数据库此时已经无法打开，甚至无法访问，那你只好听天由命喽。
3．3停止备机日志应用SQL>ALTERDATABASERECOVERMANAGEDSTANDBYDATABASECANCEL;3.4启动failover执行下列语句：SQL>ALTERDATABASERECOVERMANAGEDSTANDBYDATABASEFINISH;数据库已更改。
