With SQL Developer, you can browse database objects, run SQL statements and SQL scripts, and edit and debug PL/SQL statements. You can also run any number of provided reports, as well as create and save your own.
1. 安装JDK
rpm -Uhv jdk-6u6-linux-i586.rpm
安装在/usr/java/jdk1.6.0_06
2. 安装sql-developer
rpm -Uhv sqldeveloper-1.5.54.40-1.noarch.rpm
安装在/opt/sqldeveloper
3. 启动sql-developer
虽然在程序菜单中有sql-developer的图标，但单击并不能启动，估计是没有配置jdk的路径。所以，只能用命令行启动。
./sqldeveloper.sh 出现
Oracle SQL Developer

Type the full pathname of a J2SE installation (or Ctrl-C to quit), the path will be stored in ~/.sqldeveloper/jdk
要求输入jdk路径
/usr/java/jdk1.6.0_06
之后，终于看到sqldeveloper的启动图面。
