                   how to setup jacorb dev env
1:download JacORB_2_2

       http://www.jacorb.org/download.html
  download ant
       http://ant.apache.org/bindownload.cgi

2:extact JacORB_2_2.jar to d:\JacORB_2_2

3:setup sys environment

       set ANT_HOME=
       set JAVA_HOME=
       set JACORB_HOME=d:\JacORB_2_2
       set PATH=%PATH%;%ANT_HOME%\bin;%JAVA_HOME%\bin;%JACORB_HOME%\bin;
       set CLASSPAHT=.;%CLASSPAHT%;%ANT_HOME%\lib\ant.jar;%JACORB_HOME%\lib\jarorb.jar;%JACORB_HOME%\lib\idl.jar\;%JACORB_HOME%\lib\logkit-1.2.jar

4:rename %JACORB_HOME%\etc\jacorb_properties.template to %JACORB_HOME%\etc\jacorb.properties
  and modify the 50th line to 53th line to
 
       #ORBInitRef.NameService=file:/y:/nsiona.ref
      
ORBInitRef.NameService=file://d://test//NS_Ref
      
#ORBInitRef.NameService=http://www.x.y.z/~user/NS_Ref
      
#ORBInitRef.TradingService=http://www.x.y.z/~user/TraderRef
 
  modify 618th line to
       jacorb.naming.ior_filename=d://test//NS_Ref

5:rename  %JACORB_HOME%\jacotemplate.bat to %JACORB_HOME%\jaco.bat
 
  and modify related env variable
 
  rename   %JACORB_HOME%\idltemplate.bat to %JACORB_HOME%\idl.bat
  
  and modify related env variable

 

6:  use ant compile and build idl and java

     cd  %JACORB_HOME%\demo\grid  

     run ant
   
     the generate class file in %JACORB_HOME%\classes  and generated java file in %JACORB_HOME%\demo\grid

7: open a new cmd window:
          cd %JACORB_HOME%   ns
 
   you can see the following result:   
       [ configuration jacorb loaded from file %JAORB_HOME%\etc\jacorb.properties]

   open a new cmd window:
          cd %JACORB_HOME%   jaco demo.grid.Server
  you can see the following result:   
  [ configuration jacorb loaded from file %JAORB_HOME%\etc\jacorb.properties]
  
  open a new cmd window:
          cd %JACORB_HOME%   jaco demo.grid.client
    you can see the following result:   
 
  [ configuration jacorb loaded from file D:\work\nj\JACORB\etc\jacorb.properties]
   Height = 31
   Width = 14
   Old value at (30,13): 0.21
   Setting (30,13) to 470.11
   New value at (30,13): 470.11
   MyException, reason: This is only a test exception, no harm done :-)
   done.

 

oracle的分析函數(shù)over 及開窗函數(shù) 一：分析函數(shù)over Oracle從8.1.6開始提供分析函數(shù)，分析函數(shù)用于計算基于組的某種聚合值，它和聚合函數(shù)的不同之處是 對于每個組返回多行，而聚合函數(shù)對于每個組只返回一行。 下面通過幾個例子來說明其應(yīng)用。                                        1：統(tǒng)計某商店的營業(yè)額。              date       sale      1           20      2           15      3           14      4           18      5           30     規(guī)則：按天統(tǒng)計：每天都統(tǒng)計前面幾天的總額     得到的結(jié)果：     DATE   SALE       SUM     ----- -------- ------     1      20        20           --1天                2      15        35           --1天＋2天                3      14        49           --1天＋2天＋3天                4      18        67            .               5      30        97            .       2:統(tǒng)計各班成績第一名的同學(xué)信息     NAME   CLASS S                              ----- ----- ----------------------     fda    1      80                          ffd    1      78                          dss    1      95                          cfe    2      74                          gds    2      92                          gf     3      99                          ddd    3      99                          adf    3      45                          asdf   3      55                          3dd    3      78                       通過：        --     select * from                                                                            (                                                                                 select name,class,s,rank()over(partition by class order by s desc) mm from t2     )                                                                                 where mm=1     --     得到結(jié)果：     NAME   CLASS S                       MM                                                                                             ----- ----- ---------------------- ----------------------     dss    1      95                      1                           gds    2      92                      1                           gf     3      99                      1                           ddd    3      99                      1                   注意：     1.在求第一名成績的時候，不能用row_number()，因為如果同班有兩個并列第一，row_number()只返回一個結(jié)果               2.rank()和dense_rank()的區(qū)別是：       --rank()是跳躍排序，有兩個第二名時接下來就是第四名       --dense_rank()l是連續(xù)排序，有兩個第二名時仍然跟著第三名             3.分類統(tǒng)計 (并顯示信息)     A   B   C                           -- -- ----------------------     m   a   2                           n   a   3                           m   a   2                           n   b   2                           n   b   1                           x   b   3                           x   b   2                           x   b   4                           h   b   3    select a,c,sum(c)over(partition by a) from t2                    得到結(jié)果：    A   B   C        SUM(C)OVER(PARTITIONBYA)          -- -- ------- ------------------------    h   b   3        3                            m   a   2        4                            m   a   2        4                            n   a   3        6                            n   b   2        6                            n   b   1        6                            x   b   3        9                            x   b   2        9                            x   b   4        9                               如果用sum，group by 則只能得到    A   SUM(C)                                -- ----------------------    h   3                          m   4                          n   6                          x   9                          無法得到B列值           ＝＝＝＝＝ select * from test 數(shù)據(jù): A B C 1 1 1 1 2 2 1 3 3 2 2 5 3 4 6 ---將B欄位值相同的對應(yīng)的C 欄位值加總 select a,b,c, SUM(C) OVER (PARTITION BY B) C_Sum from test A B C C_SUM 1 1 1 1 1 2 2 7 2 2 5 7 1 3 3 3 3 4 6 6 ---如果不需要已某個欄位的值分割,那就要用 null eg: 就是將C的欄位值summary 放在每行后面 select a,b,c, SUM(C) OVER (PARTITION BY null) C_Sum from test A B C C_SUM 1 1 1 17 1 2 2 17 1 3 3 17 2 2 5 17 3 4 6 17   求個人工資占部門工資的百分比 SQL> select * from salary;

由于一些原因，最近要復(fù)習(xí)一些東西，所以就把JMS的東西再復(fù)習(xí)一遍，以下便是例子

jms 中最重要的幾個概念destination，ACKNOWLEDGE，subscribe,durable subscribe

destination：topic queque
  queue簡單點說就是1:1 一個消息只能由一個consumer去消費，別的consumer來消費的時候已經(jīng)沒了，先到先得
topic簡單點說就是1:N 一個消息可以由多個consumer來消費，誰來消費都有
 subscribe，拿topic來說如果當(dāng)前訂閱不是持久訂閱，只有再訂閱后生產(chǎn)者生產(chǎn)得消息才能被consumer得到，持久訂閱只要沒有被consumer消費，早晚會消費這個消息
 
 
 
 一下是幾個例子
 
 queuesend：queque消息產(chǎn)生
 queuereceive：queque消息得消費
 topicsend ：topic消息得產(chǎn)生
 topicreceive1：topic消息的非訂閱
 topicrecieve2：topic消息的持久訂閱
 
 這個例子實在WEBLOGIC814上測試過的，當(dāng)然要定義JMSSERVER,FACTORY,DESTINATION。
