搭建过程备注:
1. 虚拟机软件Vmware 8.0 Workstation,Windows 2008 Enterprise Server, Sql Server 2008 R2。
2. 俩个节点平台版本必须一致,都为企业版。
3. 与构建Windows 2003群集不同,不能使用vmware的共享磁盘机制。Windows 2008集群对存储要求很高,不支持SCSI硬盘做集群。
    本次使用starwind 5.4代替vmware的共享磁盘实现群集存储。
4. 搭建Windows集群需要3台虚拟机:2个节点+1台存储。
5. 搭建SqlServer 2008集群需要4替虚拟机:2个节点+1台DC+1台存储。

搭建顺序:
1. 安装DC+DNS服务器。
2. 安装集群节点, 配置双网卡,域登录。
3. 安装群集磁盘服务器
4. 在集群节点上配置iSCSI发起。
5. 在集群节点上安装“故障转移群集”功能。
6. 进行故障转移群集验证和创建。
7. 至此,Windows集群环境安装完毕。
8. 在集群节点上按群集方式安装SqlServer 2008。
9. SqlServer 2008集群环境构建完毕。

神一样的软件,膜拜ing...
连我这天生kernel iptable有缺陷的都能用。

当前版本:2.04.
还是个Open Source的,改天一定要好好观摩一番的。

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

下面的例子实现把一个整数的各个位上的数字相加,通过这个例子我们再次理解 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;
