Starting Oracle Enterprise Manager 10g Database Control ................

 在 $ORACLE_HOME/jdk/jre/lib 和 $ORACLE_HOME/jre/1.4.2/lib/ 目录下都有多种字符集字体配置文件，将中文字符集替换成默认的font.properties

然后清理一下cache，cache所在的目录$ORACLE_HOME/oc4j/j2ee/oc4j_applications/applications/em/em/cabo/images/cache/zhs

删除该目录下所有的gif文件，重新启动OEM即可
