源端测试：

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

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，，hdfs等都可以完美结合。
