DB2 basics

CREATE DATABASE command, DB2 creates a number of documents. These files include log files, configuration information, historical documents and three table spaces. The three table spaces are:

SYSCATSPACE: This is a store directory where DB2 system, DB2 system directory to track all objects associated with metadata.

TEMPSPACE1: DB2 to place the intermediate results of the temporary workspace.

USERSPACE1: By default all user objects (tables and indexes) is located where.

In cataloging the database on the client there are three ways:

Use discovery (discovery) of the automated configuration

Use Access Summary (access profile) automated configuration

Manual configuration

Configuring DB2 client to access remote DB2 database server and another is to use automation to access summary. Access summary contains the client for a DB2 server database cataloging the information needed.

And use the same found in the use of access to the outline, do not need to make DB2 client can connect to the DB2 server communications to provide any detailed information.

There are two access summary:

Server to access the summary is created from the DB2 server. They contain the DB2 server has been cataloging all the instances and databases.

Summary of client access from a client for another client to copy the database has been cataloged and / or client settings (DBM CFG and the CLI / ODBC).

Both outline can be exported from a DB2 system, then import to another DB2 system.

CLR 4.0 new content in abnormal state of confusion

Abnormal state of confusion

Some people call it Super exception. Refers not catch the exception, disrupting the process of the state, cause crashes, or do not want to see the process leading to behavior, like insanity. CLR4.0 not catch the exception made for a configurable processing mechanism. Consider the following procedure. In CLR2.0 years, this catch (Exception ex) of all possible exceptions are caught. In CLR4.0 where, by default, will not take effect this super catch, if abnormal will cause the program to stop.

class Program
static void Main (string [] args)
SaveFile ("file.txt");
Console.ReadLine ();
public static void SaveFile (string fileName)
FileStream fs = new FileStream (fileName, FileMode.Create);
catch (Exception ex)
Console.WriteLine ("File open error");
throw new IOException ();

Because of some special circumstances, need to change the default strategy. CLR 4.0 provides two means of customized

[HandleProcessCorruptedStateExceptions] method of labeling (Method attribute)

Methods need a super catch by adding the label. Take effect can make a super catch, as follows:

public static void SaveFile (string fileName)
FileStream fs = new FileStream (fileName, FileMode.Create);
catch (Exception ex)
Console.WriteLine ("File open error");
throw new IOException ();

Note: This form can only take effect within this method. In other places, or the default by CLR4.0 manner. config configuration file if you want to change this policy throughout the application level, the configuration file in config write

EST on January 4 (Beijing time on January 5) news: just a few months before Red Hat acquired JBoss Inc., JBoss founder, but now have been thinking about quitting the Make Fu Lou Ray.

Red Hat said in a statement, Fu Lou Ray in early December for personal reasons to leave temporarily, is expected to be in a few months back. According to Lou Rui Fu auto-response e-mail, said he was the fourth child born as a temporary leave, he will return to the company on March 15.

However, Rui Fu Lou JBoss Inc. issued an e-mail some of my colleagues is another version, he said, because he temporarily left the Red Hat on Red Hat's development prospects are skeptical.

Flo Ray in December when the media explained: "I intend to take the time to take care of the family and myself. I have Red Hat put a lot of feelings and investment, but I get less and less. With of you was a pleasure to do, perhaps that period of time is the pinnacle of my short career. "

Rui Fu Lou founded in 2001, JBoss Inc.. Rui Fu Lou's had contact and Red Hat, but both sides did not respond.

Lou Rui Fu is a frank person, since he joined the Red Hat, he still did not change their practices. In the last year in November to accept e weekly interview, Rui Fu Lou complained: "I thought after the company was acquired by Red Hat can get a lot from its huge investment in R & D budget, which I agreed to join the main reason for the Red Hat 1. but my personal view, things are not as I expected that.

Urgent situation of 3G intellectual property rights on how long the operator toddler

Peking University Professor Zhang Ping On the 3G intellectual property rights that, at present, the most critical in the negotiations is to some people behind each standard for 3G patent pool solid analysis, the workload can be imagined. Zhang example, in her v. Philips DVD launched a patent to be invalid patent research, only research funding spent more than ten million, while the subject from the second half of 2005 to 2006 the end of June, time-consuming nearly a year. Thus the three major 3G standards for the large number of patents involved, the huge funds needed can be imagined.

Professor Zhang presented a key issue, this analysis by whom, a moment is a tough question to answer.

However, in an interview with reporters found a good sign, present some basic telecommunications operators in the survey commissioned by third-party companies in related businesses with the 3G and its patent distribution, some by their own commitment Institute Lai related work, though, this survey only operators around the business and related patents, but the business had never been aware of the intellectual property rights would be affected operators, this is a huge step forward.

Prevent the situation quietly

China Telecom Beijing Research Institute of Zhang Ying Tang Zhuren communication industry in China in about the current status of said intellectual property protection, compared to telecom operators still in the initial state of intellectual property protection. Statistically, the end of 2005, the number of patent applications, operators are in double digits, with Huawei, ZTE can not be compared to such manufacturers, even with NTT so far from foreign telecom operators. Worthy of our attention is received from the State Intellectual Property Office figures, NTT applications in China has thousands of patents, a large number of international carriers in China for patent, on the future development of our carriers is extremely negative.

Current with the strategic transformation of telecom operators, carriers operating activities for the business innovation, service innovation, technological innovation, innovation activities, innovation networks are more and more involved in intellectual property rights is also increasing. Basic telecommunications operators and other companies operating in force, foreign carriers and even personal checks began to highlight the intellectual property disputes. Operators have begun to realize the importance of intellectual property protection, began to carry out awareness of intellectual property protection, primarily to guard against technical and business risks. But the launch of this campaign has just started, many problems faced.

Attention to the patent gold content

Basic telecom operators have set the standard for patent application and staff, and also have in-house approach has introduced some incentives for staff to award the patent application in order to encourage employees to participate in technological innovation.

"Patented invention into patent, utility model patents and design patents of three parts, basic telecom operators pay more attention to the invention patent, because this part of the gold content of patents is the largest. Of course, operators do not consider the use of patent to make money. "an insider said operator.

However, it is understood, and large business and technology sector compared to carriers to obtain certificates in intellectual property and patent agents specializing in intellectual property rights were not numerous. Nevertheless, the current operator of patent applications grew a few years ago several times, this is a good sign.

Breach of international standards for

For the carriers, in addition to patents and intellectual property there is a very important task, namely to participate in international standards organizations, at present, China's major operators are participating in track and standards of work, basically in accordance with international standards, industry standards and enterprise standards based. In this regard, China's telecom operators, China Mobile, work more, go farther. It is understood that China Mobile in August 2002 proposed the first patent application - "an Internet-based short messaging systems and data transfer method" (Monternet CMPP Agreement), realization of a zero patent applications in China Mobile breakthrough. To August 2005, China Mobile to join hands together overseas carriers Vodafone HSDPA launch joint specification version 1.0, created to promote the development of new industry technology model, creating a significant and far reaching. The end of 2005 to complete the "Patent Strategy of China Mobile," the report is the first China Mobile study on patent strategy. The report for the standardization of China Mobile into the first camp as soon as possible to provide a strategic direction.

Participation in international standards in editing and development, China Mobile sent people to participate in various international standards organizations, in September 2003, Liu Yi, China Mobile was elected vice chairman of OMA Organization Location Group, China Mobile achieved technical work in OMA Organization Group positions breakthrough. To March 2005, Huang Yuhong 3GPP SA working group was elected Vice-Chairman, representatives of Chinese companies to achieve a senior management breakthrough 3GPP.

Although the basic operators have done a considerable amount of work, but more abundant in the 3G business and foreign operators to enter the local telecommunications services market, the premise, these is not enough, then how can we more to play out the great potential of our operators, or a worthwhile research.

Consciousness gradually led

Zhang Ying Tang Zhuren analysis, 3G era arrives, telecom operators in a full-service operator, will face a large number of network and service convergence, mobile and fixed network convergence, business and terminal integration issues, business innovation, R & D more and more, intellectual property issues will become increasingly severe. To sum up from now on, operators have to do six tasks.

First, the need for intellectual property development strategy, including intellectual property organization, system. Forming a target, the system of standard intellectual property system. Intellectual property strategy to consistently throughout the product development and marketing.

Second, analysis of intellectual property strategy - to grasp rules of the game, so that to know ourselves.

Third, to participate in the formulation of international rules of the game. Master the standards development, formulation, implementation, revision of rules, standards, the real interests of the winner, standards organizations and the holders of intellectual property policies, flexible application of standards organization intellectual property policies, pay attention to allow the patent, the principles of patent claims.

Fourth, we must closely follow the standards and standards organizations, holders of standard developments, and actively participate in standardization activities of the Organization, in various drafts and the motion to seek additional patent opportunities. Standard combination of patent and R & D to develop projects and products and the corresponding patent application draft standard plan, adjust, full coordination of internal and external resources.

Fifth, to create opportunities to promote standards: do not give up the opportunity to create standards. Focus on open and closed technology system utilization strategy, for effective partners.

Sixth, to vertical and horizontal alliances, joint development: to promote technical cooperation, the establishment of industry alliance formed to develop standards and intellectual property licensing group strength.

For operators, there is now a trend that can not be completely controlled by the manufacturers, hoping to take more initiative, otherwise their interests will suffer. However, to grasp the initiative was not easy, and now look at the operator's IPR protection work has just started need further exploration.

Innovation Way provoke thinking

"Patent costs to the device is not terrible, because there are many products to choose from, as the operator will choose the most cost-effective products. The real fear is that some need to be charged by the patent fee revenue, such as China Unicom The BREW business is this. "Development Strategy of China Unicom Advisory Committee, former vice president of China Unicom Yu Xiao Mountain Memories Unicom the path of intellectual property rights, said," A few years before Unicom on CDMA, has been led by China Unicom United 19 Chinese companies negotiate with Qualcomm, which is a useful attempt, because Qualcomm was eager to enter the Chinese market, it should be said, or more successful negotiations. "

Therefore, 3G is an opportunity, 3G, including the application of too many patents, in addition to WCDMA, CDMA2000 and TD-SCDMA standard three, there are, including streaming media, including the application of patents. "However, as enterprises can not innovation for innovation, can we combine the strengths and innovation to create more suitable for specific market applications." Yu Xiao-mang.

Visual Basic to create "five star" level control

Figure 1 "five-star" level control

This control looks great and provides a good graphical way to view the grade, but according to editorial experience, I find it especially cool. When the mouse hover over the bar when, Windows Media Player highlights one of the stars to show you the current float of its value on the bar, thus providing a good graphical feedback. In a variety of Web sites (including Netflix and Amazon), you can find the same type of user interface, and I think in their own applications have this feature, so I decided to create my own control. I'll use Windows Forms controls that the user interface elements to simulate the same time try to make it custom with sufficient capacity to be used in various environments.

Getting Started

The first step is to create a new Class Library project to hold the controls and empty Windows application to a test project. Although the Windows Control Library project template appears to be more appropriate, and it is well to work, but by default, the project includes user controls (user controls 鈹?General for composite control contains one or more controls for Windows Forms control), and I need is an empty class file. Next, you must present a new empty class inherits from the System.Windows.Forms.Control, which simply add a single class declaration can be achieved:

Public Class Ratings
Inherits System.Windows.Forms.Control End Class

If you try to use only IntelliSense? Add Inherits statement, will encounter a small problem: use Class Library template to start your project will not add a reference to the System.Windows.Forms assembly, so you need to manually add. At this point, be the first to add a reference to an System.Drawing.dll, because the final drawing to use custom controls. From now on, I generally follow the following steps to carry out all of the control development:

1. To add custom drawing control standards constructor, set the control style of all the necessary controls in order to correct the drawing and smooth as possible.

Public Sub New ()
Me.SetStyle (ControlStyles.AllPaintingInWmPaint, True)
Me.SetStyle (ControlStyles.DoubleBuffer, True)
Me.SetStyle (ControlStyles.ResizeRedraw, True)
Me.SetStyle (ControlStyles.UserPaint, True)
...''Add any additional initialization code here
End Sub

2. Paper record configuration control behavior and appearance may need to list the public properties.

3. All these attributes add to the private member variable (I prefer to use Hungarian notation in front of each variable to add the prefix "m_" to represent the internal variables), and includes the appropriate default values, as shown below.

Private m_FilledImage As Image
Private m_EmptyImage As Image
Private m_HoverImage As Image
Private m_ImageCount As Integer = 5
Private m_TopMargin As Integer = 2
Private m_LeftMargin As Integer = 4
Private m_BottomMargin As Integer = 2
Private m_RightMargin As Integer = 4
Private m_ImageSpacing As Integer = 8
Private m_ImageToDraw As Integer = 1
Private m_SelectedColor As Color = Color.Empty
Private m_HoverColor As Color = Color.Empty
Private m_EmptyColor As Color = Color.Empty
Private m_OutlineColor As Color = Color.Empty

Private m_selectedItem As Integer = 3
Private m_hoverItem As Integer = 1
Private m_hovering As Boolean = False

Private ItemAreas () As Rectangle

4. The properties of these variables into the process, although most of the process is fairly simple (get value, set value), but some of the process will require some additional code, I will discuss later.

5. Began to design and custom graphics code.

6. Finally, add a new event, such as clicking a specific control process or the requirements of the specific event.

The default value of properties with a specific routine

I want some of my properties

鈹?handling those attributes of color

鈹?reflect the control of other properties of the default values (such as ForeColor) and to reflect the user's system color of other values. For example, let us use only one of them can produce color HoverColor to see the default value of different methods.

The first is obvious, just in the variable declaration (or constructor) to set default values:

Private m_HoverColor As Color = _
Color.FromKnownColor (KnownColor.Highlight)

In most cases, this can work well, but there are two problems. The first question is, if the user running the application to change their system colors, how to do? After you restart the program, the control will reflect the correct color, but was not. The second question is, if the user to programmatically set the color to the default colors, how to do? There is no practical way to clear the color settings and set it to the appropriate system color. Users will naturally be set correctly for the appropriate system color, but then will return to first question. Another method is to color changes in the user's system when the traps, and the corresponding changes to your property value:

Protected Overrides Sub OnSystemColorsChanged (_
ByVal e As System.EventArgs)
Me.HoverColor = Color.FromKnownColor (KnownColor.Highlight)
Me.Invalidate ()
