Oracle SQL Developer is a new, free graphical tool that enhances productivity and simplifies database development tasks.
With SQL Developer, you can browse database objects, run SQL statements and SQL scripts, and edit and debug PL/SQL statements. You can also run any number of provided reports, as well as create and save your own.
1. 安装JDK
rpm -Uhv jdk-6u6-linux-i586.rpm
安装在/usr/java/jdk1.6.0_06
2. 安装sql-developer
rpm -Uhv sqldeveloper-1.5.54.40-1.noarch.rpm
安装在/opt/sqldeveloper
3. 启动sql-developer
虽然在程序菜单中有sql-developer的图标，但单击并不能启动，估计是
没有配置jdk的路径。所以，只能用命令行启动。
./sqldeveloper.sh 出现
Oracle SQL Developer
Copyright (c) 2008, Oracle. All rights reserved.
Type the full pathname of a J2SE installation (or Ctrl-C to quit), the path will be stored in ~/.sqldeveloper/jdk
要求输入jdk路径
/usr/java/jdk1.6.0_06
之后，终于看到sqldeveloper的启动图面 
安装Oracle10g会遇到的问题及解决方法：
1. 缺少libXp.so.6
执行命令：yum install libXp.so.6
2. 操作系统限制
修改/etc/redhat-release 把Fedora release 9改成redhat-3
3. Can't connect to X11 window server using....
以root的用户执行 xhost +
然后 su - oracle(用户)
export DISPLAY=:0
再运行runInstaller安装oracle
4. 安装界面乱码
export LANG=en
（改成export LANG=zh_CN.GB18030不管用）
界面变成英文。
Linux下安装软件，不像Windows那么简单，所以每安装成功一个软件都让我兴奋。
注意飞鸽的版本是：g2ipmsg-0.9.5
1. 安装XML-Parser
perl Makefile.PL
make
make install
2. 修改src/codeset.c
/* #define IPMSG_PROTO_CODE IPMSG_EXTERNAL_CHARCODE */
#define IPMSG_PROTO_CODE "GB2312"
3. 安装飞鸽g2ipmsg-0.9.5
configure
make
make install
4. 开启防火墙端口tcp/udp:2425
这步很重要，不然飞鸽上一个人也没有。
今天安装了Fedora9，装完之后发现竟然没有输入法！太奇怪了，Fedora8可没这现象。
Google之后，得知
yum install scim-lang-chinese，之后重启即出现输入法。
cd /u01/app/oracle/bin
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=ORCL
export ORACLE_HOME=$ORACLE_BASE
export PATH=$PATH:$ORACLE_HOME/bin
#启动监听
lsnrctl start
#关闭监听
lsnrctl stop
#启动数据库
sqlplus "/as sysdba"
sql>startup
#停止数据库
sql>shutdown immediate
#启动dbconsole服务
emctl start dbconsole
#停止dbconsole服务
emctl stop dbconsole
#启动或停止 iSQL*Plus：
isqlplusctl start | stop

安装MyEclipse时遇到
java: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.错误
解决办法：
[root@localhost software]# export LIBXCB_ALLOW_SLOPPY_LOCK=1
[root@localhost software]# yum --enablerepo=development update libxcb
执行以上两条命令，之后出现：
[root@localhost software]# export LIBXCB_ALLOW_SLOPPY_LOCK=1
[root@localhost software]# yum --enablerepo=development update libxcb

Installed NetBeans6.0,which is a java development IDE.
This is my first time to install a software under Fedora.
However,I was disappointed in NetBeans for two reason.
The first,tomcat6 who bind with NetBeans can not be shut down.
The second,java file can not be build at once after it was saved.
Installed libpcap successfully.We can not use libpcap before installation.
Study the first program of grabing packet using libpcap.
I was exciting today since I learned more.
在Fedora8下安装netbeans
命令：
# chmod +x
netbeans-6.1-ml-javaee-linux.sh (更改权限)
# ./
netbeans-6.1-ml-javaee-linux.sh (安装netbeans)
集成了Tomcat6.0.16，不过感觉还是没MyEclipse好用，两点原因：
1. Tomcat关闭不了，好奇怪。
2. 保存java文件后不马上编译class，而是到启动Tomcat时才编译所有更新过的java.
编译带有libpcap的程序一直没成功，后来才知道libpcap还需要安装！！
1. 解压libpcap（双击即可）
2. 进入刚才解开的libpcap目录，执行
#./configure
命令，生成Makefile文件
3. 输入
#make install
将生成的库安装到系统默认目录中,/usr/local/lib。
琢磨好几天，不知道详细设计文档要写些什么，参考了很多资料，
确定写以下一些内容。
详细设计文档
1.模块设计
包括输入、输出项
对于逻辑比较复杂的画出数据流图和文件结构（对每个类的说明）
2.界面设计
3.数据库设计
ER图和表结构说明
4.UML
类图、时序图等
我的目标是在三到五年的时间内，做一个类似netscout的软件。
所以又重新学习C语言。
What is NetFlow?
NetFlow is a technology developed by Cisco Systems that is also supported by many other hardware vendors. NetFlow is far easier to setup and use than other network traffic monitoring technologies that require the deployment of distributed hardware probes. Basically, the router or switch is setup to summarize every conversation incoming on each network interface and forwards it on to a collector, like Scrutinizer, where the details are compiled and displayed in an easy to understand format that allows IT professionals to analyze the behavior of their network.
ATM Layer Link
A section of an ATM Layer connection between two adjacent active ATM Layer entities (ATM-entities).
ATM链路层
ATM层的一部分，位于两个邻近的ATM层活动实体(ATM-entities)之间。
ATM Link
A virtual path link (VPL) or a virtual channel link (VCL).
ATM链路
虚通道链路(VPL)或虚路径链路(VCL)。
ATM Machine
See ATM.
ATM设备
参见ATM。
ATM Peer-to-Peer Connection
A virtual channel connection (VCC) or a virtual path connection (VPC).
ATM对等连接
虚路径连接(VCC)或虚通道连接(VPC)。
ATM Protocol Reference Model
A multidimensional protocol model consisting of 4 layers and 3 planes and serving as a point of reference for understanding, developing and implementing ATM technology. Each layer addresses a discrete set of related functions, with all layers closely interrelated. The layers include the Physical Layer, ATM Layer, ATM Adaptation Layer, and Higher Layers related to the specifics of the native user data protocol. The planes include the Control Plane, User Plane and Management Plane.
ATM 协议参考模型
一种多维协议模型，包括4个分层和3个平面，用作理解、开发和实现ATM技术的参考点。每一个分层执行一组离散的相关功能，所有分层都紧密的相互关联。这些分层包括物理层、ATM层、ATM适配层以及与原来的用户数据协议细节相关的高层。3个平面有控制平面、用户平面以及管理平面。
ATM Switch
A networking device that forwards 53-byte ATM-standard cells between different devices. These switches can be designed for both LAN and WAN environments. An ATM switch acts as both a traffic aggregator, such as when terminating unchannelized DS-3 trunks from DSLAMs, and as a multiservice switch that is capable of forwarding traffic in different ways, depending on what has to be done with it. For example, an ATM switch forwards customer IP traffic directly to an IP network by shunting it to a router or subscriber management system, frame-relay traffic to a frame switch, voice-over-ATM traffic to a voice/data gateway, or long-distance traffic to other central offices via a SONET inter-office ring.
ATM交换机
一种网络设备，在两个不同设备之间传输53字节ATM标准信元。这些交换机可以设计用于LAN（局域网）和WAN（广域网）。 ATM交换机可以用作信息传输集合器，例如可以终止来自DSLAM的未作信道使用的DS-3中继线；也可以用作多业务交换机，能够根据预先设置以不同方式传输信息。例如，ATM交换机通过将信息分流到路由器或用户管理系统、将帧中继信息分流到帧交换机、将ATM话音信息分流到话音/数据网关或者将长途信息通过SONET局间环路分流到其他市话局来将客户IP信息流直接传输到IP网络。
ATM Token Ring LAN Service Unit
The ATM TLSU provides a powerful tool for offering internetworking services over ATM networks. Emulated token rings consist of up to 64 TLSU token ring ports located anywhere in the ATM network, interconnected with PVCs. These emulated token ring networks can be completely isolated from one another to ensure security and fairness among the attached LANs. The TLSUs are designed for flexible deployment, either local to an ATM switch or at a remote site. See ATM Ethernet LAN Service Unit.
ATM令牌环服务单元
ATM TLSU提供了功能强大的工具，在ATM网络中提供网间服务。仿真令牌环最多可以由多达64个TLSU令牌环端口组成，放置在ATM网络任意位置，提供PVC间的互连。这些仿真令牌环网络可以完全独立于其他仿真令牌环，以确保连接到局域网的各仿真令牌环的安全和公平。TLSU的设计使其能够灵活应用，无论是本地环路连接ATM交换机还是远端站连接ATM交换机。参见ATM Ethernet LAN Service Unit。
ATM Traffic Descriptor
A generic list of traffic parameters that can be used to capture the intrinsic traffic characteristics of a requested ATM connection.
ATM流量描述符
一种普通的流量参数列表，可以用于获取所需的ATM连接内在流量特性。
ATM User-User Connection
An association established by the ATM Layer to support communication between two or more ATM service users (i.e., between two or more next higher entities or between two or more ATM-entities). The communications over an ATM Layer connection may be either bidirectional or unidirectional. The same Virtual Channel Identifier (VCI) is issued for both directions of a connection at an interface.
ATM用户和用户连接
ATM层建立的一种联系，支持两个或两个以上ATM服务用户（即两个或两个以上高级实体之间或两个或两个以上ATM实体之间）之间的通信。ATM层连接上的通信可以是双向的或者的单向的。在一个接口中，相同的虚路径标识符(VCI)可以沿链路双向传输。
ATMARP
ATM Address Resolution Protocol. The means of mapping IETF classical IP addresses to ATM hardware addresses. The process works in much the same way as conventional ARP, which maps network-layer addresses to the MAC (Media Access Control) layer in a LAN.
