2009年4月1日

          搭建過程備注:
          1. 虛擬機軟件Vmware 8.0 Workstation,Windows 2008 Enterprise Server, Sql Server 2008 R2。
          2. 倆個節(jié)點平臺版本必須一致,都為企業(yè)版。
          3. 與構建Windows 2003群集不同,不能使用vmware的共享磁盤機制。Windows 2008集群對存儲要求很高,不支持SCSI硬盤做集群。
              本次使用starwind 5.4代替vmware的共享磁盤實現群集存儲。
          4. 搭建Windows集群需要3臺虛擬機:2個節(jié)點+1臺存儲。
          5. 搭建SqlServer 2008集群需要4替虛擬機:2個節(jié)點+1臺DC+1臺存儲。

          搭建順序:
          1. 安裝DC+DNS服務器。
          2. 安裝集群節(jié)點, 配置雙網卡,域登錄。
          3. 安裝群集磁盤服務器
          4. 在集群節(jié)點上配置iSCSI發(fā)起。
          5. 在集群節(jié)點上安裝“故障轉移群集”功能。
          6. 進行故障轉移群集驗證和創(chuàng)建。
          7. 至此,Windows集群環(huán)境安裝完畢。
          8. 在集群節(jié)點上按群集方式安裝SqlServer 2008。
          9. SqlServer 2008集群環(huán)境構建完畢。

          神一樣的軟件,膜拜ing...
          連我這天生kernel iptable有缺陷的都能用。

          當前版本:2.04.
          還是個Open Source的,改天一定要好好觀摩一番的。

          If you meet following errors below when you try to build your source code:

           

          Checking build tools versions...

          build/core/main.mk:72:

          ************************************************************

          build/core/main.mk:73: You are attempting to build on a 32-bit system.

          build/core/main.mk:74: Only 64-bit build environments are supported beyond froyo/2.2.

          build/core/main.mk:75:

          ************************************************************

          Don’t panic, just change the code:

          build/core/main.mk

          ifeq ($(BUILD_OS),linux)

          build_arch := $(shell uname -m) 

          ---ifneq (64,$(findstring 64,$(build_arch))) 

          +++ifneq (i686,$(findstring i686,$(build_arch)))

           

          and change the code in four mk files below from “+=-m64” to “+=-m32”


          external/clearsilver/cgi/Android.mk

          external/clearsilver/java-jni/Android.mk

          external/clearsilver/util/Android.mk

          external/clearsilver/cs/Android.mk


          LOCAL_CFLAGS += -m32

          LOCAL_LDFLAGS += -m32

          end.

          I got this idea when i was surfing the web in search of a tool similar to the Nokia Pc Suite for my Linux

          This How-To  works with many NOKIA Mobile Phone, especially for Nokia 3230, 6670, 6680, 6682 e 7610, 6120, Sony Ericsson Z1010, LG U8110/8120.

          First of all, we have to grant access for Mobile Phone to “dialout” group.

          sudo gedit /etc/udev/rules.d/40-permissions.rules

          Now we have to add to the end of file:

          # NOKIA 6120
          BUS==”usb”, SYSFS{idVendor}==”0421″, SYSFS{idProduct}==”002f”, GROUP=”dialout”

          where 0421 and 002f could be different depending on your Mobile Phone.
          To check your idVendor and idProduct, we have to type on terminal

          lsusb
          Bus 003 Device 009: ID 0421:002f Nokia Mobile Phones

          Now, we have to reload udev permission file:

          sudo /etc/init.d/udev restart

          We have to add our username on group “dialout”

          gpasswd -a username dialout

          All basics configurations for USB Data Cable are completed. We can start installation of obexftp and obextool GUI. Obextool GUI is written for tk graphic library, so GUI not have a good design as GTK.

          sudo apt-get install openobex-apps libopenobex1 obexftp obextool

          If you want start obextool from terminal we have to type for the first time:

          export OBEXCMD=”obexftp -t /dev/ttyACM0 -u 1″
          obextool

          or, we can start it simply by typing:

          obextool –obexcmd “obexftp -t /dev/ttyACM0 -u 1″

          When we start Obextool we can see this error message:

          It seems, that your device does not support the memory status feature.
          Memory status will be disabled

          To solve this problem we have to set some values on obextool.cfg:

          sudo gedit /etc/obextool.cfg

          set ObexConfig(config,memstatus) 0
          set ObexConfig(config,filemove) 0

          Another error message that we can see is:

          FIle ‘/FileName/’ could not be uploaded to ‘E:/Path’!
          Please check your file permissions.

          To solve it:

          sudo gedit /etc/obextool.cfg

          set ObexConfig(config,dir_slash) 1

          Good Job! Now your Mobile Phone works well in Ubuntu Gutsy with ObexTool.
          If we want add it as Desktop Entry:

          sudo gedit /usr/share/applications/obextool.desktop

          [Desktop Entry]
          Encoding=UTF-8
          Version=1.0
          Type=Application
          Exec=/usr/bin/obextool –obexcmd “obexftp -t /dev/ttyACM0 -u 1″
          Icon=/usr/share/icons/gnome/scalable/devices/phone.svg
          Terminal=false
          Name=Obextool
          GenericName=
          Comment=Browser your Mobile Phone
          Categories=Application;Utility;

          So, you can find it in your Gnome Panel over: “Applications” -> “Accessories” -> Obextool

          下面的例子實現把一個整數的各個位上的數字相加,通過這個例子我們再次理解 connect by.

          create or replace function f_digit_add(innum integer) return number
          is
          outnum integer;
          begin
          if innum<0 then
          return 0;
          end if;
          select sum(nm) into outnum from(
          select substr(innum,rownum,1) nm from dual connect by
          rownum<length(innum)
          );
          return outnum;
          end f_digit_add;
          /

          select f_digit_add(123456) from dual;
