我用的是SUSE10 SP3来安装的Oracle 11g R2,但是在登录EM的时候发现确定取消之类的按键都是小方框，google以后找到了解决办法，，EM的乱码是由java引起的,EM的按钮是由java生成的图,因此解决此问题变成了解决java的乱码问题.
oracle 11g R2使用的是jdk1.5,jdk1.5以后有了一个简便方法来解决这个问题，只需在$JAVA_HOME/jre/lib/fonts/下建一个fallback目录，把你想在java中使用的字体复制到这个目录中即可,在oracle用户下:
$ mkdir $ORACLE_HOME/jdk/jre/lib/fonts/fallback
把windows下的字体文件simsun.ttc复制到$ORACLE_HOME/jdk/jre/lib/fonts/fallback目录下并改名simsun.ttf（可以在C:\windows\fonts下找到这个字体文件,)相应的权限改为oracle用户可用.下载见
之后需要清理一下Cache,重启EM即可:
$rm $ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/em/em/
cabo/images/cache/zhs/*.gif
$ emctl stop dbconsole
$ emctl start dbconsole
登陆Web页面查看,EM显示就可以正常显示中文了
如果部分按键还是方框的话可以多删除几次，直到中文正常显示为止。
