源端测试服务器：
服务器环境部署：
命令步骤如下：
[root@test ~]# groupadd oinstall
[root@test ~]# groupadd dba
[root@test ~]# useradd -g oinstall -G dba oracle
[root@test ~]#
修改权限：
[root@test ~]# chown -R oracle:oinstall /data
[root@test ~]#
2． 设置全局java环境变量
[root@test ~]# cat /etc/redhat-release
CentOS release 6.4 (Final)
[root@test ~]#
[oracle@test data]$ tar -zxvf jdk-8u60-linux-x64.tar.gz
在root下执行配置：
设置java环境变量：
vi /etc/profile
###jdk
export JAVA_HOME=/data/jdk1.8.0_60
export JAVA_BIN=/data/jdk1.8.0_60/bin
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
export LD_LIBRARY_PATH=/data/jdk1.8.0_60/jre/lib/amd64/server:$LD_LIBRARY_PATH
切换Oracle用户核对：
[root@test ~]# su - oracle
[oracle@test ~]$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
[oracle@test ~]$
如果不生效：
修改java环境变量：
alternatives --install /usr/bin/java java /data/jdk1.8.0_60/bin/java 100
alternatives --install /usr/bin/jar jar /data/jdk1.8.0_60/bin/jar 100
alternatives --install /usr/bin/javac javac /data/jdk1.8.0_60/bin/javac 100
update-alternatives --install /usr/bin/javac javac /data/jdk1.8.0_60/bin/javac 100
# /usr/sbin/alternatives --config java
[root@test1 data]# /usr/sbin/alternatives --config java

注释： 在目标端完全可以不安装Oracle数据库，可以和flume环境放在一起，最终刷数据到kafka的服务器接收消息。
本案例是 通过flume中转实现的，完全没有问题。
当然也可以直接将数据传输到kafka处理消息，原理都是一样的。
未来更多的大数据融合也是一个不错的方案，无论是MySQL，MongoDB，hdfs等都可以完美结合。
