Oracle 11g如何处理EM按键乱码

今天用Mac连接VMware Fusion虚拟机数据库，突然想用EM，忽然发现确定按键为乱码。如下图：

分析：解决问题就是找到正确的字体。

处理方法：

1. 通过Windows机器c:\windows\fonts下找到simsun.ttc 这样的字体文件。

2. 在$Oracle_home/jdk/jre/lib/fonts 目录下新建文件夹，名字为fallback

    [oracle@test ~]$ cd $ORACLE_HOME/jdk/jre/lib/fonts/
    [oracle@test fonts]$ mkdir fallback

3. 将simsun.ttc上传到linux机器刚刚建立的fallback目录中并改名为simsum.ttf

    ftp上传省略

    [oracle@test fallback]$ ls
    simsun.ttc
    [oracle@test fallback]$ mv simsun.ttc simsun.ttf
    [oracle@test fallback]$ ls
    simsun.ttf

4. 清理cache

    [oracle@test fallback]$ cd                /11g/app/oracle/product/11.1.0/dbhome_1/oc4j/j2ee/oc4j_applications/applications/em/em/cabo/images/cache/zhs/
    [oracle@test zhs]$ ls
    b049hVl.imx    b498zwk.imx    b70gpYl.imx    bb5DgWk-2.imx  bb5DgWk.imx    beeJtrj.imx
    b0byrAl.imx    b54Gjjk.imx    b8f_7mj.imx    bb5DgWk-3.gif  bb5e67kMn.imx  bf8f3pRUd.imx
    b11ZkGl.imx    b5b-vtk.imx    ba936LkSR.imx  bb5DgWk-3.imx  bbaGAYl.imx    t00MaF3.imx
    b2549BKrI.imx  b61CMCk.imx    bb06006NO.imx  bb5DgWk-4.gif  bbcbaZ4nV.imx  t0MaF3.imx
    b48tkDl.imx    b6956szjB.imx  bb5DgWk-1.imx  bb5DgWk-4.imx  beaVDSk.imx
    [oracle@test zhs]$ rm -rf *.gif

5. 重新启动EM

[oracle@test zhs]$ emctl status dbconsole

6. 打开EM，字体恢复中文正常

总结：虽然是个字体的问题，但是这里面覆盖的内容还是挺多的，本人也是通过借鉴他人的文章才处理的这么快，感谢分享文章的朋友们，又处理完个新问题，好happy。
