在腳注分割線下方出現(xiàn)一個多余空行,無法刪除。

這時,可以將“視圖”轉(zhuǎn)成“普通視圖”,雙擊正文中腳注索引,在普通視圖下方會自動出現(xiàn)腳注窗口。或者在“引用”選項(xiàng)板“腳注”中選擇“顯示備注”,可以達(dá)到同樣的效果。

在下拉列表中選擇“腳注分隔符”,此時可以對分隔符進(jìn)行編輯

此時刪除多余回車就可以了。點(diǎn)擊“默認(rèn)設(shè)置”可以對腳注分隔符的默認(rèn)格式進(jìn)行修改。

這個方法也是在網(wǎng)上看到的,自己總結(jié)了一下,方面以后查詢。
netsh interface dump > cssl.txt
這樣可以在本地目錄下生成一個cssl.txt文件。該文件記錄了當(dāng)前網(wǎng)絡(luò)的配置情況。通過執(zhí)行如下命令可以應(yīng)用cssl.txt文件中的網(wǎng)絡(luò)配置。
netsh exec cssl.txt
這樣,可以寫一個批處理文件完成網(wǎng)絡(luò)配置的切換。

1、進(jìn)入命令提示符環(huán)境
2、進(jìn)入DISKPART程序
3、輸入AUTOMOUNT ENABLE指令
4、ok,下次USB硬盤放入后就可以像XP一樣自動裝載了。

Windows 2003 server遠(yuǎn)程桌面連接數(shù)限制已經(jīng)困擾很久了,給平時的維護(hù)帶來麻煩。既然微軟不會從根本上解決這個問題,那只有通過其他方式來減少問題的發(fā)生幾率。
一、在服務(wù)器端的處理辦法如下
1. 設(shè)定已經(jīng)斷開的會話結(jié)束時間限制,這樣避免會話已經(jīng)斷開,但仍然占用一個Session
開始-運(yùn)行-gpedit.msc-計算機(jī)配置-管理模板-windows組件-終端服務(wù)-會話,右邊窗口選擇"為斷開的會話設(shè)置時間限制"-選擇"已啟用",選擇一個時間;
開始-運(yùn)行-gpedit.msc-計算機(jī)配置-管理模板-windows組件-終端服務(wù)-會話,右邊窗口選擇"到達(dá)時間限制時終止會話"-選擇"已啟用"。
2. 無限時保持連接會話,便于遠(yuǎn)程控制共享任意時候連接會話的數(shù)據(jù),也就是共享任意時候連接的遠(yuǎn)程桌面的當(dāng)時狀態(tài):
開始-管理工具-終端服務(wù)配置-服務(wù)器配置-限制每個用戶使用一個會話
3. 養(yǎng)成良好習(xí)慣,退出連接時不要直接關(guān)閉,而是使用注銷。
二、如果已經(jīng)有多個連接存在
1 可以通過命令的方式將連接斷開,這個方法在2000系統(tǒng)同樣可用;如果在任務(wù)管理器的用戶里注銷的方法:
1.1 在Command Line模式下,輸入命令query user:
C:\>query user
USERNAME SESSIONNAME ID STATE IDLE TIME LOGON TIME
>dfsadmin 0 Disc . 7/23/2007 7:53 PM
mrsadmin rdp-tcp#10 1 Active . 7/24/2007 9:31 AM
ID 0的用戶是本地登陸的,ID 1是3389登陸的用戶,正在運(yùn)行中,但是仍然占用系統(tǒng)資源和通道,我們要把它踢掉。
1.2 可通過logoff x命令來注銷id為x的登錄用戶。輸入命令:logoff 1,再用query user查詢狀態(tài)
C:\>logoff 1
C:\>query user
USERNAME SESSIONNAME ID STATE IDLE TIME LOGON TIME
>dfsadmin 0 Disc none 7/23/2007 7:53 PM
三、如果連接已經(jīng)受限制
此時通過遠(yuǎn)程登錄,可以用一個"3389DOS版"軟件來進(jìn)行牽制登錄。這個軟件只能解決windows2003系統(tǒng)的限制,2000系統(tǒng)也沒辦法。
四、超過最大連接時連接
在超過最大連接數(shù)時,通過運(yùn)行mstsc /v:IP /console命令就可以連接到遠(yuǎn)程系統(tǒng)的會話。
MSTSC [<Connection File>] [/v:<sever[:port]>] [/console] [/f[ullscreen]]
[/w:<width>/h:<height>] | /Edit"ConnectionFile" | /Migrate | /?
<Connection File>-- 指定連接的.rdp 文件的名稱。
/v:<sever[:port]>-- 指定要連接到的終端服務(wù)器。
/console -- 連接到服務(wù)器的控制臺會話。
/f -- 以全屏模式啟動客戶端。
/w: <width>-- 指定遠(yuǎn)程桌面屏幕的寬度。
/h:<height>-- 指定遠(yuǎn)程桌面屏幕的亮度。
/edit -- 打開指定的.rdp 文件來編輯。
/migrate -- 將客戶端連接管理器創(chuàng)建的舊版連接文件遷移到新的.rdp 連接文件。
/? -- 生成這個用法消息。

tracert命令
C:\Documents and Settings\Administrator>tracert /?
Usage: tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout]
[-R] [-S srcaddr] [-4] [-6] target_name
Options:
-d Do not resolve addresses to hostnames.
-h maximum_hops Maximum number of hops to search for target.
-j host-list Loose source route along host-list (IPv4-only).
-w timeout Wait timeout milliseconds for each reply.
-R Trace round-trip path (IPv6-only).
-S srcaddr Source address to use (IPv6-only).
-4 Force using IPv4.
-6 Force using IPv6.
說明
tracert(跟蹤路由)是路由跟蹤公用程序,用于確定 IP 數(shù)據(jù)包訪問目標(biāo)所采取的路徑。Tracert 命令用 IP 生存時間 (TTL) 字段和 ICMP錯誤消息來確定從一個主機(jī)到網(wǎng)路上其它主機(jī)的路由。
Tracert 工作原理
透過向目標(biāo)發(fā)送不同 IP 生存時間 (TTL) 值的"Internet 控制消息協(xié)議 (ICMP)"回
應(yīng)數(shù)據(jù)包,Tracert 診斷程序確定到目標(biāo)所采取的路由。要求路徑上的每個路由器在轉(zhuǎn)
發(fā)數(shù)據(jù)包之前至少將數(shù)據(jù)包上的 TTL 遞減 1。數(shù)據(jù)包上的 TTL 減為 0 時,路由器應(yīng)
該將"ICMP已超時"的消息發(fā)回源系統(tǒng)。
Tracert 先發(fā)送 TTL 為 1 的響應(yīng)數(shù)據(jù)包,并在隨后的每次發(fā)送過程將 TTL 遞增1,直
到目標(biāo)響應(yīng)或 TTL 達(dá)到最大值,從而確定路由。透過檢查中間路由器發(fā)回的"ICMP已
超時"的消息確定路由。某些路由器不經(jīng)詢問直接丟棄 TTL 過期的數(shù)據(jù)包,這在Trac
ert 公用程序中看不到。

所有用戶的信息都存放在該文件中。該文件中每行都代表以該用戶,每行的格式如下圖所示。因?yàn)樵撐募撬杏脩舳伎梢宰x的,為了系統(tǒng)安全,將用戶的口令信息放置在另一文件中。

/etc/shadow
該文件中存放有加密的用戶口令信息,并且該文件只有root可讀的。

如果用戶口令字段是空、*或者!,說明用戶不能登錄系統(tǒng)。需要通過passwd給用戶提供密碼,這時用戶才能登錄系統(tǒng)。
ssh登錄
默認(rèn)情況下,只有root用戶可以通過ssh遠(yuǎn)程登錄系統(tǒng)。為了使其它用戶登錄,需要修改/etc/ssh/sshd_config文件。在文件中加入下面一行:

安裝SLES 10 x86_64
分區(qū)時使用Ext3文件系統(tǒng);
選擇軟件包時,選擇"Oracle Server Base"和"C/C++ Compiler and Tools",同時保證選擇了"32Bit Runtime Environment";下面是軟件包選擇的一個截圖。

安裝SLES 10的Server Pack
使用SPident或者"cat /etc/SuSE-release"來校驗(yàn)
oracle:~ # cat /etc/SuSE-release
SUSE Linux Enterprise Server 10 (x86_64)
VERSION = 10
PATCHLEVEL = 2
oracle:~ # SPident -v
Summary (using 890 packages)
Product/ServicePack conflict match update (shipped)
SLE-10-x86_64 0 0% 325 36.5% 0 (2754 11.8%)
SLE-10-x86_64-SP1 0 0% 470 52.8% 0 (2938 16.0%)
SLE-10-x86_64-SP2 0 0% 889 99.9% 0 (2337 38.0%)
Unknown 1 0.1%
CONCLUSION: System is up-to-date!
found SLE-10-x86_64-SP2
Oracle安裝先決條件
SuSE提供了orarun來自動完成很多Oracle預(yù)安裝的任務(wù)。為了下面安裝Oracle,需要進(jìn)行如下配置。
激活oracle用戶
在安裝了Oracle Server Base之后,系統(tǒng)就自動創(chuàng)建了oracle用戶。但是,默認(rèn)的該用戶是被禁用了的。
oracle:~ # vim /etc/passwd
oracle:x:103:106:Oracle user:/opt/oracle:/bin/false
為此,我們需要激活該用戶。手工編輯/etc/passwd文件:
oracle:x:103:106:Oracle user:/opt/oracle:/bin/bash
修改oracle用戶口令
oracle:~ # passwd oracle
Changing password for oracle.
New Password:
Bad password: too simple
Reenter New Password:
Password changed.
修改Oracle環(huán)境變量
編輯/etc/profile.d/oracle.sh文件中Oracle的環(huán)境變量如下:
oracle:~ # vim /etc/profile.d/oracle.sh
# ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1
ORACLE_HOME=$ORACLE_BASE/product/10gR2/db
ORACLE_SID=ESEC
修改ORACLE_HOME和ORACLE_SID環(huán)境變量。
設(shè)置內(nèi)核參數(shù)
運(yùn)行rcoracle start命令設(shè)置內(nèi)核參數(shù)。因?yàn)檫€沒有安裝Oracle數(shù)據(jù)庫,忽略期間報的錯誤。

在安裝之前,Oracle會檢查系統(tǒng)設(shè)置燈信息是否符合要求。我們將檢查未成功的選擇為"User Verified"。

選擇"Install database Software only"

查看安裝概要并選擇安裝

下面是安裝進(jìn)程。

在安裝結(jié)束之前,系統(tǒng)會提示使用root用戶登錄,執(zhí)行下面腳本。

使用另一個窗口登錄,執(zhí)行腳本。

選擇"Exit"完成安裝。

安裝補(bǔ)丁
在Novell官方的文檔中,Sentinel需要Oracle安裝補(bǔ)丁10.2.0.3。從metalink網(wǎng)站上下載Oracle的補(bǔ)丁p5337014_10203_Linux-x86-64.zip。該補(bǔ)丁有1G多,而且下載時需要metalink的帳號才能下載。
下載后解壓,并確保使用oracle用戶運(yùn)行Disk1中的runInstaller進(jìn)行安裝。跟安裝Oracle 10g時一樣,安裝程序首先要檢查系統(tǒng)兼容性,為了在SLES 10上安裝,需要修改配置文件,使之支持在SuSE 10上的安裝。修改方法與Oracle 10g安裝時的一樣。
下圖是安裝時的歡迎界面。

首先現(xiàn)在Oracle 10g的安裝目錄。

接下來,是安裝的信息。確認(rèn)后執(zhí)行安裝。

下圖是安裝進(jìn)度。

安裝結(jié)束前,提示需要用戶以root身份手工執(zhí)行root.sh腳本。

打開另一個窗口,執(zhí)行ORACLE_HOME目錄下的root.sh腳本。

執(zhí)行完腳本后,點(diǎn)擊"OK",系統(tǒng)提示完成補(bǔ)丁安裝,點(diǎn)擊"Exit"退出系統(tǒng)安裝。

應(yīng)用關(guān)鍵補(bǔ)丁
下面,需要通過opatch工具安裝Oracle的關(guān)鍵補(bǔ)丁。同樣,首先從metalink網(wǎng)站上下載補(bǔ)丁:p5881721_10203_Linux-x86-64.zip并解壓。請確保使用oralce用戶進(jìn)行下面的操作。
進(jìn)入5881721目錄,運(yùn)行$ORACLE_HOME/OPatch/opatch apply -local。下圖是安裝過程。

輸入y之后繼續(xù)安裝。

Oracle安裝先決條件
SuSE提供了orarun來自動完成很多Oracle預(yù)安裝的任務(wù)。為了下面安裝Oracle,需要進(jìn)行如下配置。
激活oracle用戶
在安裝了Oracle Server Base之后,系統(tǒng)就自動創(chuàng)建了oracle用戶。但是,默認(rèn)的該用戶是被禁用了的。
oracle:~ # vim /etc/passwd
oracle:x:103:106:Oracle user:/opt/oracle:/bin/false
為此,我們需要激活該用戶。手工編輯/etc/passwd文件:
oracle:x:103:106:Oracle user:/opt/oracle:/bin/bash
修改oracle用戶口令
oracle:~ # passwd oracle
Changing password for oracle.
New Password:
Bad password: too simple
Reenter New Password:
Password changed.
修改Oracle環(huán)境變量
編輯/etc/profile.d/oracle.sh文件中Oracle的環(huán)境變量如下:
oracle:~ # vim /etc/profile.d/oracle.sh
# ORACLE_HOME=$ORACLE_BASE/product/10.2/db_1
ORACLE_HOME=$ORACLE_BASE/product/10gR2/db
ORACLE_SID=ESEC
修改ORACLE_HOME和ORACLE_SID環(huán)境變量。
設(shè)置內(nèi)核參數(shù)
運(yùn)行rcoracle start命令設(shè)置內(nèi)核參數(shù)。因?yàn)檫€沒有安裝Oracle數(shù)據(jù)庫,忽略期間報的錯誤。

摘要: 網(wǎng)上有很多源代碼可以實(shí)現(xiàn)Base64編碼的轉(zhuǎn)換,但是主要是對中文轉(zhuǎn)換的時候有問題。
后來在網(wǎng)上找了很多資料,發(fā)現(xiàn)原來在Java默認(rèn)的實(shí)現(xiàn)機(jī)制中,內(nèi)部使用UTF-16編碼,而所有算法是針對英文UTF-8的。因此,在對中文字符串轉(zhuǎn)換的過程中會出現(xiàn)截取錯誤。后來在源代碼的基礎(chǔ)上進(jìn)行了小的調(diào)整,最好可以實(shí)現(xiàn)Base64編碼。
下面貼出一個實(shí)現(xiàn)代碼:

suse:~ # help test
test: test [expr]
Exits with a status of 0 (true) or 1 (false) depending on
the evaluation of EXPR. Expressions may be unary or binary. Unary
expressions are often used to examine the status of a file. There
are string operators as well, and numeric comparison operators.
File operators:
-a FILE True if file exists.
-b FILE True if file is block special.
-c FILE True if file is character special.
-d FILE True if file is a directory.
-e FILE True if file exists.
-f FILE True if file exists and is a regular file.
-g FILE True if file is set-group-id.
-h FILE True if file is a symbolic link.
-L FILE True if file is a symbolic link.
-k FILE True if file has its `sticky' bit set.
-p FILE True if file is a named pipe.
-r FILE True if file is readable by you.
-s FILE True if file exists and is not empty.
-S FILE True if file is a socket.
-t FD True if FD is opened on a terminal.
-u FILE True if the file is set-user-id.
-w FILE True if the file is writable by you.
-x FILE True if the file is executable by you.
-O FILE True if the file is effectively owned by you.
-G FILE True if the file is effectively owned by your group.
-N FILE True if the file has been modified since it was last read.
FILE1 -nt FILE2 True if file1 is newer than file2 (according to
modification date).
FILE1 -ot FILE2 True if file1 is older than file2.
FILE1 -ef FILE2 True if file1 is a hard link to file2.
String operators:
-z STRING True if string is empty.
-n STRING
STRING True if string is not empty.
STRING1 = STRING2
True if the strings are equal.
STRING1 != STRING2
True if the strings are not equal.
STRING1 < STRING2
True if STRING1 sorts before STRING2 lexicographically.
STRING1 > STRING2
True if STRING1 sorts after STRING2 lexicographically.
Other operators:
-o OPTION True if the shell option OPTION is enabled.
! EXPR True if expr is false.
EXPR1 -a EXPR2 True if both expr1 AND expr2 are true.
EXPR1 -o EXPR2 True if either expr1 OR expr2 is true.
arg1 OP arg2 Arithmetic tests. OP is one of -eq, -ne,
-lt, -le, -gt, or -ge.
Arithmetic binary operators return true if ARG1 is equal, not-equal,
less-than, less-than-or-equal, greater-than, or greater-than-or-equal
than ARG2.

后來跟蹤了啟動的Shell腳本,最后發(fā)現(xiàn)是需要更改$ORACLE_HOME/bin/dbstart文件。在該文件中,定義變量PFILE:
PFILE=${ORACLE_HOME}/dbs/init${ORACLE_SID}.ora
其中,在Oracle9i中已經(jīng)通過spfile${ORACLE_SID}.ora。因此,將PFILE變量修改為:
PFILE=${ORACLE_HOME}/dbs/spfile${ORACLE_SID}.ora
同時,為了可以在關(guān)機(jī)的時候關(guān)閉數(shù)據(jù)庫,同時在$ORACLE_HOME/bin/dbshut文件中對應(yīng)的位置也需要修改PFILE文件的定義。
另外,還有一種方法,就是生成pfile。用sqlplus連接數(shù)據(jù)庫,
conn / as sysdba
create pfile from spfile;
這樣,就會參考${ORACLE_HOME}/dbs/spfileora9i.ora生成initora9i.ora這個pfile。這樣就不用改啟動腳本文件了。
以上兩種方法已經(jīng)證明都可以正常工作。

在SuSE下,由于SuSE特有的腳本管理方法,Should-Stop和Default-Stop選項(xiàng)被忽略了。同時,在腳本開始處執(zhí)行/etc/rc.status腳本,可以通過調(diào)用rc_status -v檢查啟動命令的執(zhí)行結(jié)果并彩色顯示出來。

在用Struts開發(fā)項(xiàng)目的時候遇到了一個問題,當(dāng)上傳文件時,中文文件名會出現(xiàn)亂碼問題。
于是,在Google和Baidu上面進(jìn)行了搜索。結(jié)果發(fā)現(xiàn)有無數(shù)人遇到了相同的問題,大家也都在迫切的詢問此類問題。但是回帖的結(jié)果卻讓人特別生氣!
回帖的內(nèi)容大致可分為兩類:
第一類,都是把別人的帖子轉(zhuǎn)來轉(zhuǎn)去,也不著名出處。更是有幾個人都在自己的博客上寫的內(nèi)容完全一樣,還說是自己寫的!
另一類相對要好一些,對問題進(jìn)行了解答。但是,按照他們所說的進(jìn)行了更改,根本就不能解決問題。真是不知道他們是這么解決這個問題的。
后來在玉米田http://www.yumt.com/showlog.jspe?log_id=56#71的博客上有一篇文章說道了此事,才能徹底解決這個問題。看了之后才知道,原來Struts的upload功能是對jakarta apache的commons-fileUpload進(jìn)行了封裝實(shí)現(xiàn)的。但是在實(shí)現(xiàn)時,沒有考慮到文件編碼的問題。所以,需要對struts.jar中的文件進(jìn)行修改并重新編譯打包。事實(shí)證明,這樣作問題解決了。
但是回過頭來,那些通過在JSP頁面中設(shè)置編碼方式為UTF-8或者在得到文件名進(jìn)行編碼轉(zhuǎn)譯的人是如何解決這個問題的,難道我的系統(tǒng)跟他們的不一樣嗎?
由此,可以看出很多網(wǎng)友不能夠踏踏實(shí)實(shí)的做人,人云亦云。抱著一種極其不負(fù)責(zé)任的態(tài)度,這樣作不但是自己不能真正理解問題的本質(zhì),得不到提高和進(jìn)步,更加影響了對此類問題不甚了解并渴望解答的人所誤解。
同時,一旦這種風(fēng)氣發(fā)展下去,下次提問者作為解答者的時候這種現(xiàn)象又會出現(xiàn)。如果此類現(xiàn)象愈演愈烈,勢必會對我們中國整個軟件業(yè)甚至這個中華民族帶來及其深刻的影響!
希望跟我有同感的IT同仁可以從自己做起,認(rèn)真回答網(wǎng)友的提問。我們從自己做起,從現(xiàn)在做起!
