真正解决dbca、netca、em等乱码问题(含jdk安装)
参考地址:猛击这里

注意:62位系统此方法貌似无效,会报“java.lang.UnsatisfiedLinkError: /u01/app/oracle/10.2.0/db_1/lib32/libOsUtils.so:”错误。如果谁的不报错,回帖通知我哦!


1、在Linux下安装新的JDK(JRE),我装的是1.6;
  
以下参考地址:[url=http://flyer2010.iteye.com/blog/658064]再猛击这里[/url]

1.下载jdk-6u20-linux-i586-rpm.bin 拷贝到/usr/local/目录下 

2.进入 cd /usr/local/ 

3.增加执行权限  chmod +x jdk-6u20-linux-i586-rpm.bin 

4.执行安装命令 
   ./jdk-6u20-linux-i586-rpm.bin 
   此时会生成文件jdk-6u20-linux-i586.rpm,同样给所有用户添加可执行的权限 

    #chmod +x jdk-6u20-linux-i586.rpm 

5.安装程序 
#rpm -ivh jdk-6u20-linux-i586.rpm 

6.安装完成,查看jdk的安装目录,为  /usr/java/jdk1.6.0_20 

7.设置JDK环境变量。 

#vi /etc/profile 

添加如下内容: 

export JAVA_HOME=/usr/java/jdk1.6.0_20 

export JRE_HOME=$JAVA_HOME/jre 

export PATH=$PATH:/usr/java/jdk1.6.0_20/bin 

export   CLASSPATH=.:/usr/java/jdk1.6.0_20/lib:/usr/java/jdk1.6.0_20/jre/lib 


8.在终端使用echo命令检查环境变量设置情况。 

#echo $JAVA_HOME 

#echo $CLASSPATH 

#echo $PATH 

9.检查JDK是否安装成功。 

#java -version 

10.如果看到JVM版本及相关信息,即安装成功! 



卸载linux中已经安装的jdk 

卸载步骤: 

[root@localhost local]# rpm -qa|grep jdk 
jdk-1.6.0_21-fcs.i586 
[root@localhost local]# rpm -e jdk-1.6.0_21-fcs.i586 

[root@localhost local]# rpm -qa|grep java 
sun-javadb-core-10.5.3-0.2.i386 
sun-javadb-docs-10.5.3-0.2.i386 
sun-javadb-demo-10.5.3-0.2.i386 
java-1.5.0-gcj-1.5.0.0-29.fc12.i686 


[root@localhost local]# rpm -e java-1.5.0-gcj-1.5.0.0-29.fc12.i686 
error: Failed dependencies:

        jre >= 1.5.0 is needed by (installed) openoffice.org-ure-1:3.1.1-19.14.fc12.i686 

有很多依赖关系,不让卸载,用 rpm -e --nodeps 卸载就行了 

[root@localhost local]# rpm -e --nodeps java-1.5.0-gcj-1.5.0.0-29.fc12.i686


2、修改DBCA(在$ORACLE_HOME/bin目录)命令脚本内容中所对应的JRE路径(JRE_DIR)为/usr/java/jdk1.6.0_20

3、完成(其它修改同理)。
