系统环境:
    RHEL5.3 [ 2.6.18-128.el5PAE ]
软件环境:
    10201_database_linux32.zip、jdk-6u20-linux-i586.bin
####################################################################
 
一、安装JDK开发环境
[root@localhost ~]# cp /var/ftp/upload/jdk-6u20-linux-i586.bin /usr/local/
[root@localhost ~]# cd /usr/local/
[root@localhost local]# chmod a+x jdk-6u0-linux-i586.bin
[root@localhost local]# ./jdk-6u20-linux-i586.bin
…… //根据提示完成安装
[root@localhost local]# ln -s /usr/local/jdk1.6.0_20 /usr/local/jdk
[root@localhost local]# vi /etc/profile
JAVA_HOME=/usr/local/jdk
CLASSATH=$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$PATH:%JAVA_HOME/bin
export JAVA_HOME CLASSPATH PATH
[root@localhost local]# source /etc/profile
[root@localhost local]# alternatives --install /usr/bin/java java /usr/local/jdk1.6.0_20/bin/java 1
[root@localhost local]# alternatives --install /usr/bin/javac javac /usr/local/jdk1.6.0_20/bin/javac 1
[root@localhost local]# alternatives --config java
[root@localhost local]# alternatives --config javac
