----- 如何启用 Administrator（xp、windows7）
net user Administrator /active:yes
单击“开始→运行”，输入regedit后回车，打开注册表编辑器，依次展开 "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList" 分支
将右边的Administrator的值改为1，即可让Administrator账户出现在登录的欢迎屏幕上。（如果没有Administrator的话就创建一个DWORD(32位)值类型，其它上级项目没有的话也依次创建）
----- 在PE中修改源系统的注册表
启动注册表编辑器，点击HKEY_LOCAL_MACHINE，然后点【文件】-【加载配置单元】，浏览文件，进入 Win7安装的分区 " c:\Windows\System32\config" 里面的SYSTEM、DEFAULT、SOFTWARE都可以选择，选择后让你输入名称，随便输入，如byiu输入后点确定就会在HKEY_LOCAL_MACHINE下面增加那个分支，然后就可以编辑了。
---新建administrator
点开HKEY_LOCAL_MACHINE,点开SAM，右击SAM，点击权限..在组或用户名称下点选 Administrators,点选完全控制对应的允许复选框，点击确定
在注册表编辑器窗口按F5刷新。点开："HKEY_LOCAL_MAICHINE\SAM\SAM\Domains\Account\Users\Names"
导入如下注册表，即Administrator用户：

---怎样从DOS/Linux的telnet中退出
我们经常要用到telnet来测试FTP端口，但是有一个问题估计大家都会遇到，在telnet进入某个端口后无法退出，没办法，为了继续测试只好关掉这个dos窗口，重新打开一个。这里教给你一个方法，按住ctrl+]就可以退出到
Welcome to Microsoft Telnet Client
Escape Character is 'CTRL+]'

然后再输入quit就可以完全退出了。

------------------------------------------------ selinux
查看SELinux状态：
1、/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
2、getenforce ##也可以用这个命令检查
关闭SELinux：
1、临时关闭（不用重启机器）：
setenforce 0 ##设置SELinux 成为permissive模式
##setenforce 1 设置SELinux 成为enforcing模式
2、修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可

------------------ AIX系统用户解锁
3.1 AIX用户账户锁定与解锁最佳方法
3004-303 There have been too many unsuccessful login attempts; please see
the system administrator.
与之相关的配置参数是/etc/security/login.cfg的以下配置项
logindisable=7 *7次失败登录后锁定端口
logininterval=120 *在120秒内7次失败登录才锁定端口
1、如果你可以登陆到ROOT账户，比较简单
使用chsec命令即可解锁，具体如下：
# chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s username
通过重置未成功登陆的次数即可解锁
2、如果是通过设置来锁定的用户，可以这样解锁
#【smitty user】-->【Lock / Unlock a User's Account】
或是
# chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s username
3、命令解锁
# chuser account_locked=TRUE username 给用户加锁
# chuser accout_locked=FALSE username 给用户解锁

永久生效 smit hostname
或者 smit tcpip - futher configureation - hostname -set the hostname
uname -S hostname
或者直接用命令 chdev -l inet0 -a hostname=NEW_HOSTNAME

正确更改IP 地址是用 smit tcpip 进入菜单之后，选择further configuration 再选 Network Interfaces，再选 Network Interface Selection,
再选 Change /show characteristic of a network interface来更改 IP，这样/etc/hosts就不会新加入一条记录，只需更改文件中相应的IP就行了。

--------------ORA-00845: MEMORY_TARGET not supported on this system
办法：修改/etc/fstab
tmpfs /dev/shm tmpfs defaults,size=1.5G 0 0
[root@FWDB ~]# mount -o remount /dev/shm
简单来说就是 MEMORY_MAX_TARGET 的设置不能超过 /dev/shm 的大小：
[oracle@FWDB FWDB]$ df -h | grep shm
tmpfs 2.0G 0 2.0G 0% /dev/shm
马上把它加大：
[root@FWDB ~]# cat /etc/fstab | grep tmpfs
tmpfs /dev/shm tmpfs defaults,size=4G 0 0
现在可以通过重启使这个配置生效，也可以通过重新挂载来修改其大小：
[root@FWDB ~]# mount -o remount,size=4G /dev/shm
[root@FWDB ~]# df -h | grep shm
tmpfs 4.0G 0 4.0G 0% /dev/shm
再次启动数据库，没有报错了。
二、修改/dev/shm大小
默认的最大一半内存大小在某些场合可能不够用，并且默认的inode数量很低一般都要调高些，这时可以用mount命令来管理它。
#mount -o size=1500M -o nr_inodes=1000000 -o noatime,nodiratime -o remount /dev/shm
在2G的机器上，将最大容量调到1.5G，并且inode数量调到1000000，这意味着大致可存入最多一百万个小文件。
如果需要永久修改/dev/shm的值，需要修改/etc/fstab
tmpfs /dev/shm tmpfs defaults,size=1.5G 0 0
mount -o remount /dev/shm
umount tmpfs
mount -t tmpfs shmfs -o size=3000m /dev/shm

注意：修改主机名后，需要重启系统后生效，或者切换个用户然后切换回来就OK
查看/etc/hosts文件中必须包含a fully qualified name for the server
[root@localhost lhr]# cat /etc/hosts

rpm -e --nodeps mysql-libs.x86_64
-----------------命令后rpm包被下载到了什么地方
每次在执行完yum命令后，系统都会把需要用到的rpm包放在/var/cache/yum/这个目录下，但下载源的不同还是会放在不同源目录下。
find /var/cache/yum/ -name kmod-oracleasm*
-------------- rhel5.5
# mkdir /media/cdrom
编辑 /etc/fstab 文件，在文件尾部添加如下内容，以便开机自动挂载光盘：
[root@localhost ~]# tail -1 /etc/fstab

[root@localhost ~]#
[root@localhost ~]# mount -a
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]#
清空并编辑 YUM 源配置文件
清空 /etc/yum.repos.d/rhel-debuginfo.repo 文件并新增以下内容：
[root@localhost ~]# cp /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.bak
[root@localhost ~]# cat /etc/yum.repos.d/rhel-debuginfo.repo

# vi /etc/yum.repos.d/my.repo
[Oracle]

如果是RHEL或者CentOS，请先将/etc/yum.repos.d下面的文件删除或者移动到别的目录下，RHEL创建方法和OEL一样，CentOS则baseurl=file:///mnt/ 即可，因为CentOS的repodata目录就在光盘根下。

生产环境下，oracle 9I下sga大概8G，pga大概6g，需要导入一个2.7g以上的大表到成产库中，由于是同事着手运用imp工具的默认buffer=30K，用时大概一个小时还没有结果，考虑到pga还是很大的，跟同事商议加上buffer=409600000设置buffer大概400M的，15分钟内imp完成。当然运用impdp然后运用parallel=n效率当然更加理想了！

----linux下批量查找/替换文本内容
--一般在本地电脑上批量替换文本有许多工具可以做到，比如sublime text ,但大多服务器上都是无图形界面的，为此收集了几条针对linux命令行实现批量替换文本内容的命令：
--1.批量查找某个目下文件的包含的内容，例如：
# grep -rn "要找查找的文本" ./
[oracle@rhel6_lhr dpdump]$ grep -rn "ALTER SESSION SET EVENTS" ./
./spool_result.sql:2:ALTER SESSION SET EVENTS '10150 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:3:ALTER SESSION SET EVENTS '10904 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:4:ALTER SESSION SET EVENTS '25475 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:5:ALTER SESSION SET EVENTS '10407 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:6:ALTER SESSION SET EVENTS '10851 TRACE NAME CONTEXT FOREVER, LEVEL 1';
./spool_result.sql:7:ALTER SESSION SET EVENTS '22830 TRACE NAME CONTEXT FOREVER, LEVEL 192 ';
--2.批量查找并替换文件内容。
# sed -i "s/要找查找的文本/替换后的文本/g" `grep -rl "要找查找的文本" ./`
例如替换被病毒修改的一段脚本：
sed -i "s/<script type=\"text\/javascript\" src='http:\/\/t.cn\/RhyQ1GN'><\/script>//g" `grep -rl "<script type=\"text\/javascript\" src='http:\/\/t.cn\/RhyQ1GN'><\/script>" ./`
----将STORAGE(INITIAL开头的行整行替换为STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
-- 必须加点和星号和最后的g ，否则不能整行替换
sed 's/^STORAGE(INITIAL.*/STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645/g' a.txt > b.txt

要安装LogMiner工具，必须首先要运行下面这样两个脚本：
$ORACLE_HOME/rdbms/admin/dbmslm.sql
$ORACLE_HOME/rdbms/admin/dbmslmd.sql
这两个脚本必须均以SYS用户身份运行。其中第一个脚本用来创建DBMS_LOGMNR包，该包用来分析日志文件。第二个脚本用来创建DBMS_LOGMNR_D包，该包用来创建数据字典文件。
---设置单独的表空间

在Windows下手工卸载RAC的步骤：
①　开始->设置->控制面板->管理工具->服务，或运行services.msc打开服务，停止所有Oracle服务
②　删除Oracle和GRID的安装目录
③　删除C:\Program Files\Oracle目录
④　删除C:\windows\temp和C:\temp以及C:\Users\Administrator\Oracle下的文件
⑤　运行regedit，打开注册表编辑器，选择HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE，删除该项
⑥　运行regedit，打开注册表编辑器，选择HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services，滚动这个列表，删除所有Oracle开头的项
⑦　运行regedit，打开注册表编辑器，选择HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application，删除所有Oracle入口
⑧　开始->设置->控制面板->系统->高级->环境变量，删除环境变量CLASSPATH和PATH中有关Oracle的设定

---GRID_HOME权限修复
方法1：11gR2可以deconfig crs的配置，然后重新跑root.sh即可。重新跑root.sh脚本并不影响数据库，所以无需担心（个人推荐的一种方式）.
$ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -verbose
$ORACLE_HOME/root.sh
方法2：根据Mos文档提供的建议通过 $GRID_HOME/crs/install/rootcrs.pl -init 或 roothas.pl -init进行解决. rootcrs.pl –init是在PSU>11.2.0.3.6下执行的，如果PSU<11.2.0.3.6可以执行如下两条命令来实现同样的效果
<GRID_HOME>/crs/install/rootcrs.pl -unlock
<GRID_HOME>/crs/install/rootcrs.pl -patch
For 11.2:
For clustered Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./rootcrs.pl -init
For Standalone Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./roothas.pl -init
For 12c:
For clustered Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./rootcrs.sh -init
For Standalone Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./roothas.sh -init

4.安装过程中出现问题的时候认真查看日志，安装日志路径：$ORACLE_HOME/cfgtoollogs\emca\
5.OEM运行日志：$ORACLE_HOME/$hostname_$oracle_sid/sysman/log
6.建议重新创建，在oracle用户下：
单机： emca -config dbcontrol db -repos recreate
集群： emca -config dbcontrol db -repos recreate -cluster
若是集群环境，则在创建之前先在grid用户下执行如下代码：
-----sqlplus / as sysasm ASM实例 GRID 用户下执行
SYS@+ASM1> create user asmsnmp identified by xxx;
SYS@+ASM1> grant sysdba to asmsnmp;
SYS@+ASM1> alter user asmsnmp identified by xxx;
SYS@+ASM1> alter system set remote_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=ZFZHLHRDB-scan)(PORT=1521))))' sid='*';
SYS@+ASM1> alter system register;
7.启动和关闭维护命令，oracle用户下：export ORACLE_UNQNAME=$DB_UNIQUE_NAME ,数据库唯一名，进程：ps -ef| grep em
启动： emctl stop dbconsole
关闭： emctl stop dbconsole
运行状态：emctl status dbconsole

-----aix 修改系统时间
linux下用date -s "20131215 09:02:25"把时间设为2013年12月15日9点2分25秒。
而aix呢？它不认-s这个参数：
date -n mmddHHMMYY，mm表示月分，dd表示日期，HH表示小时，MM表示分钟，YY表示年份。
如：date -n 1215090213表示把当前时间设为2013年12月15日9点2分，秒数无法修改。
-----自动同步linux时间
1、下载ntpdate
注：有些版本是没有自带ntpdate，因此需要下载
# yum install -y ntpdate
2、调整时区为上海，也就是北京时间+8区
注：想改其他时区也可以去看看/usr/share/zoneinfo目录
# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
# yes | cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
3、使用NTP来同步时间
# ntpdate us.pool.ntp.org
4、定时同步时间（每隔10分钟同步时钟）
# crontab -l >/tmp/crontab.bak
# echo "*/10 * * * * /usr/sbin/ntpdate us.pool.ntp.org | logger -t NTP" >> /tmp/crontab.bak

------------------------- Linux 权限
755表示该文件所有者对该文件具有读、写、执行权限，该文件所有者所在组用户及其他用户对该文件具有读和执行权限。
linux文件权限一般都以8进制表示，格式为abc的形式，其中a,b,c各为一个数字，分别表示User、Group、及Other对该文件的操作权限；
如果文件权限用二进制表示那么是9位bit，从左至右，1-3位数字代表文件所有者的权限，4-6位数字代表同组用户的权限，7-9数字代表其他用户的权限；
而具体的权限是由数字来表示的，读取的权限等于4，用r表示；写入的权限等于2，用w表示；执行的权限等于1，用x表示；
通过4、2、1的组合，得到以下几种权限：0（没有权限）；4（读取权限）；5（4+1 | 读取+执行）；6（4+2 | 读取+写入）；7（4+2+1 | 读取+写入+执行）
常用的linux文件权限如下：
444 r--r--r--
600 rw-------
644 rw-r--r--
666 rw-rw-rw-
700 rwx------
744 rwxr--r--
755 rwxr-xr-x
777 rwxrwxrwx
这里以755为例：
1-3位7等于4+2+1，rwx，所有者具有读取、写入、执行权限；
4-6位5等于4+1+0，r-x，同组用户具有读取、执行权限但没有写入权限；
7-9位5，同上，也是r-x，其他用户具有读取、执行权限但没有写入权限。
rwxr-xr-x：当前文件对所属用户为可读可写可运行，对所属组为可读可运行，对其他用户为可读可运行
Linux 中对于文件的权限分为可读(r),可写(w),可运行(x),其对应的 8进制代码是
可读(r):4,可写(w):2,可运行(x):1 ,如果有多个权限，那么对应的8进制数字就是各个单独权限数字相加，3个数字中，第一个代表文件所属用户，第二个代表文件所属组，第三个代表其他。那么对于所属用户为可读可写可运行就是 4+2+1 = 7, 对于所属组为可读可运行就是 4+1 = 5 ,对于其他用户为可读可运行就是 4+1 = 5, 合起来就是 755 的权限

-------------------------------------------------------------------------------- CHM --------------------------------------------------------------------------------
chm文件是由Windows目录下的hh.exe这个文件打开的，但是它的搜索功能却不是这个文件能办到的，所以， chm能打开却无法搜索，或者是MSDN能打开却无法搜索，即使重装也无济于事，有的人遇到这个问题还从其他人的机器上重新拷贝了hh.exe这个文件，发现仍然不能解决这个问题。其实解决这个问题，很简单，在运行里面执行以下命令：
regsvr32 hhctrl.ocx
regsvr32 itss.dll
regsvr32 itircl.dll //这个很重要，是关于全文搜索的。
问题就可以解决了。最后一个命令特别重要，以前我找到的解决方法只有前面两个，没有最后一个，还是解决不了问题的。

-----如何清除Shared Pool中某条SQL语句？
如果数据库版本为Oracle 10g以前，那么只能清空整个Shared Pool，命令为：“ALTER SYSTEM FLUSH SHARED_POOL;”。在Oracle 10g中提供了一个包DBMS_SHARED_POOL，该包可以实现该功能。若该包没有安装，则可以通过$ORACLE_HOME/rdbms/admin/dbmspool.sql进行安装。在Oracle 10.2.0.4中有BUG（MOS为：751876.1），需要通过设置事件来规避该问题，命令为：“ ALTER SESSION SET EVENTS '5614566 TRACE NAME CONTEXT FOREVER';”
使用这种方法，就可以精确的将一个SQL从共享池中删除，从而使得Oracle为这个SQL重新生成执行计划。这种方法只针对单个SQL语句，使得解决问题的同时不会造成任何的误伤。
