----- 如何啟用 Administrator（xp、windows7）
net user Administrator /active:yes
單擊“開始→執行”，輸入regedit後回車，開啟登錄檔編輯器，依次展開 "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList" 分支
將右邊的Administrator的值改為1，即可讓Administrator賬戶出現在登入的歡迎螢幕上。（如果沒有Administrator的話就建立一個DWORD(32位)值型別，其它上級專案沒有的話也依次建立）
----- 在PE中修改源系統的登錄檔
啟動登錄檔編輯器，點選HKEY_LOCAL_MACHINE，然後點【檔案】-【載入配置單元】，瀏覽檔案，進入 Win7安裝的分割槽 " c:\Windows\System32\config" 裡面的SYSTEM、DEFAULT、SOFTWARE都可以選擇，選擇後讓你輸入名稱，隨便輸入，如byiu輸入後點確定就會在HKEY_LOCAL_MACHINE下面增加那個分支，然後就可以編輯了。
---新建administrator
點開HKEY_LOCAL_MACHINE,點開SAM，右擊SAM，點選許可權..在組或使用者名稱稱下點選 Administrators,點選完全控制對應的允許核取方塊，點選確定
在登錄檔編輯器視窗按F5重新整理。點開："HKEY_LOCAL_MAICHINE\SAM\SAM\Domains\Account\Users\Names"
匯入如下注冊表，即Administrator使用者：

---怎樣從DOS/Linux的telnet中退出
我們經常要用到telnet來測試FTP埠，但是有一個問題估計大家都會遇到，在telnet進入某個埠後無法退出，沒辦法，為了繼續測試只好關掉這個dos視窗，重新開啟一個。這裡教給你一個方法，按住ctrl+]就可以退出到
Welcome to Microsoft Telnet Client
Escape Character is 'CTRL+]'
Microsoft Telnet>
然後再輸入quit就可以完全退出了。

檢視SELinux狀態：
1、/usr/sbin/sestatus -v ##如果SELinux status引數為enabled即為開啟狀態
SELinux status: enabled
2、getenforce ##也可以用這個命令檢查
關閉SELinux：
1、臨時關閉（不用重啟機器）：
setenforce 0 ##設定SELinux 成為permissive模式
##setenforce 1 設定SELinux 成為enforcing模式
2、修改配置檔案需要重啟機器：
修改/etc/selinux/config 檔案
將SELINUX=enforcing改為SELINUX=disabled
重啟機器即可

------------------ AIX系統使用者解鎖
3.1 AIX使用者賬戶鎖定與解鎖最佳方法
3004-303 There have been too many unsuccessful login attempts; please see
the system administrator.
與之相關的配置引數是/etc/security/login.cfg的以下配置項
logindisable=7 *7次失敗登入後鎖定埠
logininterval=120 *在120秒內7次失敗登入才鎖定埠
1、如果你可以登陸到ROOT賬戶，比較簡單
使用chsec命令即可解鎖，具體如下：
# chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s username
通過重置未成功登陸的次數即可解鎖
2、如果是通過設定來鎖定的使用者，可以這樣解鎖
#【smitty user】-->【Lock / Unlock a User's Account】
或是
# chsec -f /etc/security/lastlog -a unsuccessful_login_count=0 -s username
3、命令解鎖
# chuser account_locked=TRUE username 給使用者加鎖
# chuser accout_locked=FALSE username 給使用者解鎖

或者 smit tcpip - futher configureation - hostname -set the hostname
uname -S hostname

正確更改IP 地址是用 smit tcpip 進入選單之後，選擇further configuration 再選 Network Interfaces，再選 Network Interface Selection,
再選 Change /show characteristic of a network interface來更改 IP，這樣/etc/hosts就不會新加入一條記錄，只需更改檔案中相應的IP就行了。

--------------ORA-00845: MEMORY_TARGET not supported on this system
辦法：修改/etc/fstab
tmpfs /dev/shm tmpfs defaults,size=1.5G 0 0
[root@FWDB ~]# mount -o remount /dev/shm
簡單來說就是 MEMORY_MAX_TARGET 的設定不能超過 /dev/shm 的大小：
[oracle@FWDB FWDB]$ df -h | grep shm
tmpfs 2.0G 0 2.0G 0% /dev/shm
馬上把它加大：
[root@FWDB ~]# cat /etc/fstab | grep tmpfs
tmpfs /dev/shm tmpfs defaults,size=4G 0 0
現在可以通過重啟使這個配置生效，也可以通過重新掛載來修改其大小：
[root@FWDB ~]# mount -o remount,size=4G /dev/shm
[root@FWDB ~]# df -h | grep shm
tmpfs 4.0G 0 4.0G 0% /dev/shm
再次啟動資料庫，沒有報錯了。
二、修改/dev/shm大小
預設的最大一半記憶體大小在某些場合可能不夠用，並且預設的inode數量很低一般都要調高些，這時可以用mount命令來管理它。
#mount -o size=1500M -o nr_inodes=1000000 -o noatime,nodiratime -o remount /dev/shm
在2G的機器上，將最大容量調到1.5G，並且inode數量調到1000000，這意味著大致可存入最多一百萬個小檔案。
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

生產環境下，oracle 9I下sga大概8G，pga大概6g，需要匯入一個2.7g以上的大表到成產庫中，由於是同事著手運用imp工具的預設buffer=30K，用時大概一個小時還沒有結果，考慮到pga還是很大的，跟同事商議加上buffer=409600000設定buffer大概400M的，15分鐘內imp完成。當然運用impdp然後運用parallel=n效率當然更加理想了！

----linux下批量查詢/替換文字內容
--一般在本地電腦上批量替換文字有許多工具可以做到，比如sublime text ,但大多伺服器上都是無圖形介面的，為此收集了幾條針對linux命令列實現批量替換文字內容的命令：
--1.批量查詢某個目下檔案的包含的內容，例如：
# grep -rn "要找查詢的文字" ./
[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.批量查詢並替換檔案內容。
# sed -i "s/要找查詢的文字/替換後的文字/g" `grep -rl "要找查詢的文字" ./`
例如替換被病毒修改的一段指令碼：
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>" ./`
----將STORAGE(INITIAL開頭的行整行替換為STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
-- 必須加點和星號和最後的g ，否則不能整行替換
sed 's/^STORAGE(INITIAL.*/STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645/g' a.txt > b.txt

$ORACLE_HOME/rdbms/admin/dbmslm.sql
$ORACLE_HOME/rdbms/admin/dbmslmd.sql
這兩個指令碼必須均以SYS使用者身份執行。其中第一個指令碼用來建立DBMS_LOGMNR包，該包用來分析日誌檔案。第二個指令碼用來建立DBMS_LOGMNR_D包，該包用來建立資料字典檔案。
---設定單獨的表空間
create tablespace ts_LOGMNR datafile '/sda4/u01/app/oracle/oradata/orcllinux/logmnr.dbf' size 1G autoextend on next 2M ;
exec dbms_logmnr_d.set_tablespace('ts_logmnr');
---------------- 附加日誌
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
alter database add supplemental log data(primary key) columns;
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY, UNIQUE INDEX) COLUMNS;
SELECT SUPPLEMENTAL_LOG_DATA_MIN,SUPPLEMENTAL_LOG_DATA_pk FROM V$DATABASE;
---找到需要進行日誌挖掘的歸檔日誌

在Windows下手工解除安裝RAC的步驟：
①　開始->設定->控制皮膚->管理工具->服務，或執行services.msc開啟服務，停止所有Oracle服務
②　刪除Oracle和GRID的安裝目錄
③　刪除C:\Program Files\Oracle目錄
④　刪除C:\windows\temp和C:\temp以及C:\Users\Administrator\Oracle下的檔案
⑤　執行regedit，開啟登錄檔編輯器，選擇HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE，刪除該項
⑥　執行regedit，開啟登錄檔編輯器，選擇HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services，滾動這個列表，刪除所有Oracle開頭的項
⑦　執行regedit，開啟登錄檔編輯器，選擇HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application，刪除所有Oracle入口
⑧　開始->設定->控制皮膚->系統->高階->環境變數，刪除環境變數CLASSPATH和PATH中有關Oracle的設定
⑨　從桌面上、STARTUP（啟動）組、程式選單中，刪除所有有關Oracle的組和圖示
⑩　重新啟動計算機，重起後才能完全刪除Oracle所在目錄
若個別檔案不能刪除，則說明該檔案與某個Windows服務相關聯，可以先把相關聯的服務停止後再刪除。

方法1：11gR2可以deconfig crs的配置，然後重新跑root.sh即可。重新跑root.sh指令碼並不影響資料庫，所以無需擔心（個人推薦的一種方式）.
$ORACLE_HOME/crs/install/rootcrs.pl -deconfig -force -verbose
$ORACLE_HOME/root.sh
方法2：根據Mos文件提供的建議通過 $GRID_HOME/crs/install/rootcrs.pl -init 或 roothas.pl -init進行解決. rootcrs.pl –init是在PSU>11.2.0.3.6下執行的，如果PSU<11.2.0.3.6可以執行如下兩條命令來實現同樣的效果
<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/

6.建議重新建立，在oracle使用者下：
單機： emca -config dbcontrol db -repos recreate
叢集： emca -config dbcontrol db -repos recreate -cluster
若是叢集環境，則在建立之前先在grid使用者下執行如下程式碼：
-----sqlplus / as sysasm ASM例項 GRID 使用者下執行
SYS@+ASM1> create user asmsnmp identified by xxx;
SYS@+ASM1> grant sysdba to asmsnmp;

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.啟動和關閉維護命令，oracle使用者下：export ORACLE_UNQNAME=$DB_UNIQUE_NAME ,資料庫唯一名，程式：ps -ef| grep em
啟動： emctl stop dbconsole
關閉： emctl stop dbconsole
執行狀態：emctl status dbconsole

linux下用date -s "20131215 09:02:25"把時間設為2013年12月15日9點2分25秒。
而aix呢？它不認-s這個引數：
date -n mmddHHMMYY，mm表示月分，dd表示日期，HH表示小時，MM表示分鐘，YY表示年份。
如：date -n 1215090213表示把當前時間設為2013年12月15日9點2分，秒數無法修改。
-----自動同步linux時間
1、下載ntpdate
注：有些版本是沒有自帶ntpdate，因此需要下載
# yum install -y ntpdate
2、調整時區為上海，也就是北京時間+8區
注：想改其他時區也可以去看看/usr/share/zoneinfo目錄
# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
# yes | cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
3、使用NTP來同步時間
# ntpdate us.pool.ntp.org
4、定時同步時間（每隔10分鐘同步時鐘）
# crontab -l >/tmp/crontab.bak
# echo "*/10 * * * * /usr/sbin/ntpdate us.pool.ntp.org | logger -t NTP" >> /tmp/crontab.bak

------------------------- Linux 許可權
755表示該檔案所有者對該檔案具有讀、寫、執行許可權，該檔案所有者所在組使用者及其他使用者對該檔案具有讀和執行許可權。
linux檔案許可權一般都以8進製表示，格式為abc的形式，其中a,b,c各為一個數字，分別表示User、Group、及Other對該檔案的操作許可權；
如果檔案許可權用二進位制表示那麼是9位bit，從左至右，1-3位數字代表檔案所有者的許可權，4-6位數字代表同組使用者的許可權，7-9數字代表其他使用者的許可權；
而具體的許可權是由數字來表示的，讀取的許可權等於4，用r表示；寫入的許可權等於2，用w表示；執行的許可權等於1，用x表示；
通過4、2、1的組合，得到以下幾種許可權：0（沒有許可權）；4（讀取許可權）；5（4+1 | 讀取+執行）；6（4+2 | 讀取+寫入）；7（4+2+1 | 讀取+寫入+執行）
常用的linux檔案許可權如下：
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
這裡以755為例：
1-3位7等於4+2+1，rwx，所有者具有讀取、寫入、執行許可權；
4-6位5等於4+1+0，r-x，同組使用者具有讀取、執行許可權但沒有寫入許可權；
7-9位5，同上，也是r-x，其他使用者具有讀取、執行許可權但沒有寫入許可權。
rwxr-xr-x：當前檔案對所屬使用者為可讀可寫可執行，對所屬組為可讀可執行，對其他使用者為可讀可執行
Linux 中對於檔案的許可權分為可讀(r),可寫(w),可執行(x),其對應的 8進位制程式碼是
可讀(r):4,可寫(w):2,可執行(x):1 ,如果有多個許可權，那麼對應的8進位制數字就是各個單獨許可權數字相加，3個數字中，第一個代表檔案所屬使用者，第二個代表檔案所屬組，第三個代表其他。那麼對於所屬使用者為可讀可寫可執行就是 4+2+1 = 7, 對於所屬組為可讀可執行就是 4+1 = 5 ,對於其他使用者為可讀可執行就是 4+1 = 5, 合起來就是 755 的許可權

chm檔案是由Windows目錄下的hh.exe這個檔案開啟的，但是它的搜尋功能卻不是這個檔案能辦到的，所以， chm能開啟卻無法搜尋，或者是MSDN能開啟卻無法搜尋，即使重灌也無濟於事，有的人遇到這個問題還從其他人的機器上重新拷貝了hh.exe這個檔案，發現仍然不能解決這個問題。其實解決這個問題，很簡單，在執行裡面執行以下命令：
regsvr32 hhctrl.ocx
regsvr32 itss.dll
regsvr32 itircl.dll //這個很重要，是關於全文搜尋的。
問題就可以解決了。最後一個命令特別重要，以前我找到的解決方法只有前面兩個，沒有最後一個，還是解決不了問題的。
如果chm格式檔案出現“網頁不能瀏覽”的錯誤，在該文件上點選滑鼠右鍵，解除鎖定即可。

-----如何清除Shared Pool中某條SQL語句？
如果資料庫版本為Oracle 10g以前，那麼只能清空整個Shared Pool，命令為：“ALTER SYSTEM FLUSH SHARED_POOL;”。在Oracle 10g中提供了一個包DBMS_SHARED_POOL，該包可以實現該功能。若該包沒有安裝，則可以通過$ORACLE_HOME/rdbms/admin/dbmspool.sql進行安裝。在Oracle 10.2.0.4中有BUG（MOS為：751876.1），需要通過設定事件來規避該問題，命令為：“ ALTER SESSION SET EVENTS '5614566 TRACE NAME CONTEXT FOREVER';”
使用這種方法，就可以精確的將一個SQL從共享池中刪除，從而使得Oracle為這個SQL重新生成執行計劃。這種方法只針對單個SQL語句，使得解決問題的同時不會造成任何的誤傷。
