Tuxedo中间件开发和管理
一、Introduction
1、Middleware目前流行叫做Application Server；
2、C語言編寫；
3、Tuxedo走下坡路，因為BS架構流行；但CS仍有BS無法取代的使用場合；
4、Tuxedo server provides services to Tuxedo clients；
?? ----server就是進程，用ps可以查看；
?? ----services可以理解為一個一個的函數；
5、什么是短連接、長連接？
6、Bulletin Board Liaison（BBL：Tuxedo administration process）；
7、客戶端：native client，remote client；
8、unix命令：ipcs；
9、The tuxedo API：ATMI；
10、Tuxedo buffer types：
11、通訊方式：Request/Reply（synchronous、asynchronous）；conversations；unsolicited messages；publish and subscribe；store and forward；
12、work distribution：
13、configuration and administration：centralized
14、domain：a tuxedo application；a bussiness progrem built upon the tuxedo system；
15、Conmand Line Utilities；GUI Administration Console；
二、Installing Tuxedo
1、Tuxedo Administrator
----職責同DBA，但更簡單；
2、安裝：官方安裝文檔；
3、目錄結構；
4、卸載：卸載shell或刪除全部目錄；
三、Deploying a Basic Application
1、部署tuxedo自帶例子，.../atmi/simpapp，小寫轉換大寫；
2、部署步驟如下圖：
?????
（1）配置應用的環境變量
可以在tux.env中配置（臨時環境變量）：
tuxedo@campost:~/simpapp> cat tux.env
TUXDIR=/opt/tuxedo/tuxedo11gR1; export TUXDIR
JAVA_HOME=$TUXDIR/jre; export JAVA_HOME
JVMLIBS=$JAVA_HOME/lib/amd64/server:$JAVA_HOME/jre/bin
PATH=$TUXDIR/bin:$JAVA_HOME/bin:$PATH; export PATH
COBCPY=:$TUXDIR/cobinclude; export COBCPY
COBOPT="-C ANS85 -C ALIGN=8 -C NOIBMCOMP -C TRUNC=ANSI -C OSEXT=cbl"; export COBOPT
SHLIB_PATH=$TUXDIR/lib:$JVMLIBS:$SHLIB_PATH; export SHLIB_PATH
LIBPATH=$TUXDIR/lib:$JVMLIBS:$LIBPATH; export LIBPATH
LD_LIBRARY_PATH=$TUXDIR/lib:$JVMLIBS:$LD_LIBRARY_PATH; export LD_LIBRARY_PATH
WEBJAVADIR=$TUXDIR/udataobj/webgui/java; export WEBJAVADIR
LANG=C; export LANG
APPDIR=/home/tuxedo/simpapp; export APPDIR
TUXCONFIG=/home/tuxedo/simpapp/tuxconfig; export TUXCONFIG
里面的環境變量有些不是必須的，例如SHLIB_PATH用于HP-UX，LIBPATH用于IBM AIX，而LD_LIBRARY_PATH用于linux。
配置完之后執行：
tuxedo@campost:~/simpapp> . ./tux.env
也可以在tuxedo用戶的.profile中添加以上環境變量，是它們在進入tuxedo時自動生效
（2）配置ubbconfig，編譯程序
先修改文本形式的ubbconfig：
vi ubbsimpapp
僅修改以下幾個地方即可：
*RESOURCES
IPCKEY????????? 123456
*MACHINES
DEFAULT:
??????????????? APPDIR="/home/tuxedo/simpapp"
??????????????? TUXCONFIG="/home/tuxedo/simpapp/tuxconfig"
??????????????? TUXDIR="/opt/tuxedo/tuxedo11gR1"
campost???????? LMID=simple
tuxedo需要二進制形式的ubbconfig，需要使用tmloadcf得到二進制的ubbconfig：
tuxedo@campost:~/simpapp> tmloadcf -y ubbsimple
可以使用tmunloadcf命令從二進制形式的ubbconfig得到文本形式的ubbconfig。
編譯服務端程序：
tuxedo@campost:~/simpapp> buildserver -o simpserv -f simpserv.c -s TOUPPER
服務端程序及服務名不能任意命名，因為在配置文件中有配置。
編譯客戶端程序：
tuxedo@campost:~/simpapp> buildserver -o simpserv -f simpserv.c -s TOUPPER
客戶端可執行程序可任意命名。
（3）啟動tuxedo應用，運行程序
tuxedo@campost:~/simpapp> tmboot -y
Booting all admin and server processes in /home/tuxedo/simpapp/tuxconfig
INFO: Oracle Tuxedo, Version 11.1.1.3.0, 64-bit, Patch Level (none)
Booting admin processes ...
exec BBL -A :
??????? process id=22679 ... Started.
Booting server processes ...
exec simpserv -A :
??????? process id=22680 ... Started.
2 processes started.
tuxedo@campost:~/simpapp> ./client "Hello, world"
Returned string is: HELLO, WORLD
四、Basic Tuxedo Configuration
1、tuxedo配置文件ubbxxx，既要文本文件，又要二進制文件，也是因為慣例，按說不應該必須讓管理員手工tmloadcf生成二進制配置文件；
2、配置文件結構如下圖：
?????3、resource三個參數必不可少：
IPCKEY：IPC通信KEY，32,769—262,142，Tuxedo占用內存很少，該值盡量配大些；
MASTER：主Tuxedo節點的邏輯機器名（Logical Machine Name），與OS機器名（Real Machine Name，uname -a）映射，但不是OS機器名；
??????? Machine中有OS機器名與邏輯機器（LMID）名的對應。
MODEL：單機是SHM，多機網絡是MP；
4、配置文件的聯機文檔為ads.pdf，其他參數調優時使用；
五、Administration and Additional Configuration
1、MIB：Management Information Base；
2、操作tuxedo有三種方式：（1）APIs；（2）tmadmin；（3）圖形界面；
?? 對于學習來說，APIs用于開發，tmadmin用于管理，圖形界面不用學習；
3、tmboot：
?????? 如：tmboot -s dispApp；
4、tmshutdown：
??????? 如：tmshutdown -s dispApp；
????? tmshutdown -c；
5、tmadmin：
??????

6、tuxedo tmadmin和oracle sqlplus輸入錯誤按回退鍵無法刪除，出現“^H”，用delete鍵才能刪除：
設置回退鍵有效命令：stty erase ^H，但此時delete鍵又無效了；
7、一些其他命令：
?????
如：
> pclt
??? LMID???????? User Name?????? Client Name??? Time??? Status? Bgn/Cmmt/Abrt

8、常用參數配置

#domain管理的服務組

GWTDOMAIN SRVGRP=GROUP2 SRVID=3 REPLYQ=Y
#WSL??? SRVGRP=GROUP2 SRVID=4 CLOPT="-A -- -n //132.10.10.11:9600 -T 20 -N 300 -m 50 -M 100 -x 2 -c 1024 -p 40000 -P 41000"
WSL???? SRVGRP=GROUP2 SRVID=4 CLOPT="-A -- -n //132.10.10.17:9600 -T 20 -N 300 -m 50 -M 100 -x 2 -c 1024 -p 40000 -P 41000"
*SERVICES
ServiceDisp
ServiceAcp
ServiceDlv
ServiceDownload
ServiceBroadcast
ServiceTransfer
ServiceEmail
production@campost:~/cpst/campost/config>
說明：
CLOPT：“--”符左邊是服務參數，“-A”是服務全部啟動，“--”符右邊是要傳給客戶端的參數，“-t on”是支持多線程；
MIN：最少啟動服務數；
MAX：最多啟動服務數；較好的方法是把MIN和MAX設置相等，把所有服務全啟動，因為現在服務器內存已不是系統瓶頸了；
-p：允許設置MIN和MAX；
LDBAL：是否啟動load balance功能；如果啟動了load balance功能，services可以設置負載因子和優先級參數；
9、ULOG：User LOG file
默認放在APPDIR下，可以在resource中加參數ULOGPFX參數指定其他目錄；
出現錯誤，分析ULOG時，一般先分析第一個錯誤，因為后面很多錯誤都可能是第一個錯誤導致的；
10、tmtrace：分析atmi系統調用的詳細信息
export tmtrace=on之后在ULOG中查看詳細信息，在開發時使用，因為要寫大量的日志；
??????
11、tmshutdown多次不能關掉時：
kill -9
rpcm
