制作Ubuntu安装U盘

Posted on 2016/07/02 by neohope — No Comments ↓

本文以Ubuntu为例，讲解一下Linux安装U盘的制作方法。

首先，下载安装盘的ISO镜像。
http://releases.ubuntu.com/

然后要知道，自己的BIOS模式是什么，是Legecy还是UEFI。这个通过查看操作系统信息或BIOS设置就可以知道。

如果是Legecy模式：
1、下载工具universal usb installer
2、制作安装U盘。
3、重启，从U盘启动即可

如果是UEFI模式：
1、那只需要将盘格式化为FAT32模式，然后将64位的ISO镜像解压到盘的根目录就好了。
2、保证在盘的根目录可以开单到UEFI目录。
3、重启，关闭BIOS中的安全启动保护，从而可以用U盘启动
4、重启，从U盘启动即可
5、安装后，记得打开BIOS中安全安全启动保护

Oracle数据泵导入导出

Posted on 2016/06/23 by neohope — No Comments ↓

首先要说明一下，数据泵只可以在服务端运行，而且数据泵要用到DIRECTORY对象。

一、新建DIRECTORY并授权

#创建DIRECTORY
CREATE DIRECTORY dump_dir AS 'DIRECTORY_FULL_PATH';

#授权
GRANT READ, WRITE ON DIRECTORY dump_dir TO user_id;

二、数据泵导出数据

#导出表
expdp user_id/user_pwd directory=dump_dir dumpfile=table01.dmp tables=table01 logfile=table01.log

#导出方案
expdp user_id/user_pwd directory=dump_dir dumpfile=schema01.dmp schemas=schema01 logfile=schema01.log

#导出表空间
expdp user_id/user_pwd directory=dump_dir dumpfile=tbs01.dmp tablespaces=tbs01 logfile=tbs01.log

#导出数据库
expdp user_id/user_pwd directory=dump_dir dumpfile=db01.dmp full=y logfile=db01.log

三、数据泵导入数据

#导入表
impdp user_id/user_pwd directory=dump_dir dumpfile=table01.dmp tables=table01 

#导入方案
impdp user_id/user_pwd directory=dump_dir dumpfile=schema01.dmp schemas=schema01

#导入表空间
impdp user_id/user_pwd directory=dump_dir dumpfile=tbs01.dmp tablespaces=tbs01

#导入数据库
impdp user_id/user_pwd directory=dump_dir dumpfile=db01.dmp full=y

Windows创建符号连接

Posted on 2016/06/23 by neohope — No Comments ↓

1、mklink
该命令可以创建符号链接、硬链接及快捷方式。

MKLINK [[/D] | [/H] | [/J]] Link Target

        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    specifies the new symbolic link name.
        Target  specifies the path (relative or absolute) that the new link
                refers to.

2、fsutil hardlink
该命令可以创建硬链接。

create          Create a hardlink
list            Enumerate hardlinks on a file

3、junction
该工具是SYSINTERNALS提供的，可以新增或删除符号链接。

The first usage is for displaying reparse point information, the
second usage is for creating a junction point, and the last for
deleting a junction point:
usage: junction.exe [-s] [-q] <file or directory>
       -q     Don't print error messages (quiet)
       -s     Recurse subdirectories

usage: junction.exe <junction directory> <junction target>
       example: junction d:\link c:\windows

usage: junction.exe -d <junction directory>

JMX获取Tomcat管理信息

Posted on 2016/06/21 by neohope — No Comments ↓

1、首先配置JVM
JVM要放到NTFS卷中，在JVM路径下找到jmxremote.access及jmxremote.password.template两个文件。
将jmxremote.password.template复制一份为jmxremote.password，对运行用户可读，对普通用户不可读。

2、配置Tomcat启动参数
修改catalina.bat，增加下面一行

SET "JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.port=8686 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true"

3、启动Tomcat

COM+服务授权配置

Posted on 2016/06/12 by neohope — No Comments ↓

远程调用COM+时经常会遇到下面的错误：

Error: 70
Description: Permission denied

这时就要进行授权（这个方法只能调通Win7与Win7，无法调通Win7与XP）。

首先是服务端配置：

1、首先在COM+服务端新建一个用户，比如COMPTEST，用户一定要加入组Distributed COM Users。（XP没有这个组，我用了Administrator权限依然不可以。。。）

2、在COM+服务端运行

#32位系统32位COM，64位系统64位COM
dcomcnfg
#64位系统32位COM
comexp.msc -32

3、在“服务组件-》计算机-》我的电脑”右键，属性
默认属性-》确认DCOM服务开启

4、在“服务组件-》计算机-》我的电脑-》COM+应用程序”，对应的COM+应用程序上，右键，属性
安全性-》授权，取消勾选
安全性-》安全性级别，改为Process
安全性-》将身份验证级别修改为无
安全性-》将模拟级别改为匿名
激活-》激活类型改为应用程序

5、在在“服务组件-》计算机-》我的电脑-》COM+应用程序-》对应COM+应用程序-》组件”，对应的COM+组件上，右键，属性
安全性-》授权，取消勾选

然后是客户端配置
1、在客户端，添加服务端的COMPTEST用户凭证

搞定！

PS：如果还不行的话，再设置下面的内容
1、在“服务组件-》计算机-》我的电脑”右键，属性
默认属性-》将默认身份验证基本修改为无
默认属性-》将默认模拟级别改为匿名
COM安全-》访问权限，添加Everyone及匿名用户
COM安全-》启动与激活权限，添加Everyone及匿名用户
2、然后要修改一下本地安全策略，让匿名用户与Everyone权限相同
3、然后修改本地安全策略，让DCOM可以Everyone操作

本篇文章介绍了如何写一个简单的COM+客户端（CSharp）。

1、首先要导入COM组件编译时生成的TBL文件（ATL），并引用COM组件的Assembly（CS）

2、代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ATLCOMPLib;
using CSDll;

namespace CSTestComp
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                testATL();
                //testCS();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

            Console.ReadKey();
        }

        static void testATL()
        {
            Type justATestCOMPType = System.Type.GetTypeFromProgID("ATLCOMP.JustATestCOMP", "172.16.172.3");
            IJustATestCOMP svc = (IJustATestCOMP)System.Activator.CreateInstance(justATestCOMPType);
            int c = svc.Add(1, 2);
            System.Console.WriteLine(c);
            String retValue = svc.SayHiTo("com+");
            System.Console.WriteLine(retValue);
            System.Console.Read();
        }

        static void testCS()
        {
            Type justATestCSSvcType = System.Type.GetTypeFromProgID("CSDll.JustATestCSSvc", "172.16.172.3");
            IJustATestCSSvc svc = (IJustATestCSSvc)System.Activator.CreateInstance(justATestCSSvcType);
            int c = svc.Add(1, 2);
            System.Console.WriteLine(c);
            String retValue = svc.SayHiTo("com+");
            System.Console.WriteLine(retValue);
            System.Console.Read();
        }
    }
}

如果是本机测试（带IP），一般不会遇到权限问题

PS：
用了一晚上时间，只能调通Win7与Win7之间远程调用，无法调通Win7与XP之间远程调用（总是各种提示Access is Denied）。
如果有谁调通过，麻烦留言告诉我一下。谢谢！

    WScript.Echo "Error: " & Err.Number
    WScript.Echo "Error (Hex): " & Hex(Err.Number)
    WScript.Echo "Source: " &  Err.Source
    WScript.Echo "Description: " &  Err.Description
    'Err.Clear
    '退出程序
    WScript.Quit(Err.Number)
End If

'On Error Goto 0

WScript.Echo obj.Add(1,2)
WScript.Echo obj.SayHiTo("dcom")


set obj=Nothing

2、运行

cscript testCOMP.vbs

本篇文章介绍了如何用C#写一个简单的COM+组件(Dll)。

1、新建一个C# Class Library项目“CSDll”，项目增加引用“System.EnterpriseServices”

2、项目中，新增一个接口文件IJustATestCSSvc.cs，Guid要自己生成

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;

namespace CSDll
{
    [ComVisible(true)]
    [InterfaceType(ComInterfaceType.InterfaceIsDual)]
    [Guid("F243B9A5-A171-49AD-AA68-47CCF6A68A2A")]
    public interface IJustATestCSSvc
    {
        int Add(int a, int b);
        String SayHiTo(String someOne);
    }
}

3、项目中，新增一个类文件JustATestCSSvc.cs，Guid要自己生成

using System;
using System.Collections.Generic;
using System.EnterpriseServices;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;

namespace CSDll
{
    
    [ComVisible(true)]
    [Guid("0C7660A9-37EC-4A39-AB0E-E936B2B24A98")]
    [ProgId("CSDll.JustATestCSSvc")]
    public class JustATestCSSvc : ServicedComponent,IJustATestCSSvc
    {

        public int Add(int a, int b)
        {
            return a + b;
        }

        public String SayHiTo(String someOne)
        {
            return "Hi " + someOne + "!";
        }
    }
}

4、项目的AssemblyInfo.cs中，增加下面几行

[assembly: ApplicationName("CSDll")]
[assembly: ApplicationActivation(ActivationOption.Server)]
[assembly: ApplicationAccessControl(false,
AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent)]

5、项目属性->Application->Assembly Infomation->Make Assembly COM-Visible->打勾

6、项目属性->Signing->Sign the assembly->打勾
项目属性->Signing->Choose a strong name key file->New

7、编译

8、注册

#这里一定要用正确版本的gacutil及RegAsm
C:\VBS\DNFW4\gacutil.exe /i CSCOMTest.dll
C:\VBS\DNFW4\RegAsm.exe CSCOMTest.dll
C:\VBS\DNFW4\RegSvcs.exe /c CSCOMTest.dll

9、反注册

#这里一定要用正确版本的gacutil及RegAsm
C:\VBS\DNFW4\gacutil.exe /u CSCOMTest
C:\VBS\DNFW4\RegAsm.exe /u CSCOMTest.dll
C:\VBS\DNFW4\RegSvcs.exe /u CSCOMTest.dll

10、查看注册结果（COM+）

#32位系统32位COM，64位系统64位COM
dcomcnfg
#64位系统32位COM
comexp.msc -32

COM+简单示例（01）

Posted on 2016/06/12 by neohope — No Comments ↓

本篇文章介绍了如何用ATL写一个简单的COM+组件(Dll)。

1、VC新建工程，ATL->ATL Project(名称为ATLCOMP)->类型选择Dynamic Library(DLL)->勾选Support COM+ 1.0->Finish

2、工程视图，ATLCOMP工程，右键->Add->Class->ATL->ATL COM+ 1.0 Component->类名为JustATestCOMP，ProgID为ATLCOMP.JustATestCOMP

3、切换到类视图，ATLCOMP项目下的IJustATestCOMP接口上右键Add Method
名称：Add
参数1：[in]LONG a
参数2：[in]LONG b
参数3：[out,retval]LONG* c

4、类视图，ATLCOMP项目下的IJustATestCOMP接口上右键Add Method
名称：SayHiTo
参数1：[in]BSTR someOne
参数2：[out,retval]BSTR* retValue

5、打开JustATestCOMP.cpp完成两个函数

STDMETHODIMP CJustATestCOMP::Add(LONG a, LONG b, LONG* c)
{
	// TODO: Add your implementation code here
	*c = a+b;

	return S_OK;
}


STDMETHODIMP CJustATestCOMP::SayHiTo(BSTR someOne, BSTR* retValue)
{
	// TODO: Add your implementation code here
	CComBSTR sResult("Hi ");
	CComBSTR sName(someOne);
	CComBSTR sMark("!");
	sResult.AppendBSTR(sName);
	sResult.AppendBSTR(sMark);
	*retValue = sResult.Copy();

	return S_OK;
}

6、编译

7、注册

regsvr32 ATLCOMP.dll

8、反注册

regsvr32 /u ATLCOMP.dll

9、注册到COM+
9.1打开组件管理器

#32位系统32位COM，64位系统64位COM
dcomcnfg
#64位系统32位COM
comexp.msc -32

9.2选择到“Components Services-》Computers-》My Computer->COM+ Applications”
9.3右键“New-》Application（ATLCOMP）”
9.4选择到“Components Services-》Computers-》My Computer->COM+ Applications->ATLCOMP->Components”
9.5右键“New-》Component-》导入已注册的组件-》选择ATLCOMP.JustATestCOMP-》确定”

10、COM+反注册
找到对应的应用或组件，直接删除就好了
