fc9下oracle sqldeveloper安装日志

本来打算就使用sqlplus命令行访问oracle，发现实在是不好用，比windows下的pl/sql难用不说，比起Linux下的mysql命令行也难用很多，
特别是那个重复上一个命令，不像普通的mysql命令行，或者shell命令行那样用一个上箭头就可以重复上一条命令，还很好修改，sqlplus下用/来实现，
不知道怎么修改，应该是我sqlplus用的不熟，算了，我还是省省，于是我改用gui

1）官方网站下载
Oracle SQL Developer RPM for Linux (This zip does not include a JDK)

2）安装
rpm -Uhv sqldeveloper-1.5.54.40-1.noarch.rpm

如果没有jdk还需要安装

2.1)

换成jdk6　ok

2.2)
界面不能输入中文，查询结果也出现乱码

google了很多，都说是没有设置NLS_LANG
必须export NLS_LANG=服务端的设置（select userenv('language') from dual;）
比如：SIMPLIFIED CHINESE_CHINA.UTF8

还特意google了很多关于oracle nls,发现误入歧途，还是解决不了问题　
郁闷了一天

2.3)偶然发现同事joshua也用了sqldeveloper没有乱码
发现其解决办法是：
ln -s /usr/share/fonts/cjkunifonts-uming/uming.ttf $your_java_home/jre/lib/fonts/fallback/zysong.ttf
按照此法终于ok
问同事是怎么找到答案的，原来他在用linux 下用netbean也遇到过这种情况，所以如法炮制
