Oracle SQL Developer is a new, free graphical tool that enhances productivity and simplifies database development tasks.

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. 安裝JDK
rpm -Uhv jdk-6u6-linux-i586.rpm  
  
安裝在/usr/java/jdk1.6.0_06

2. 安裝sql-developer
rpm -Uhv sqldeveloper-1.5.54.40-1.noarch.rpm
   
安裝在/opt/sqldeveloper

3. 啟動sql-developer
雖然在程序菜單中有sql-developer的圖標，但單擊并不能啟動，估計是沒有配置jdk的路徑。所以，只能用命令行啟動。
   
./sqldeveloper.sh  出現
Oracle SQL Developer

Type the full pathname of a J2SE installation (or Ctrl-C to quit), the   path will be stored in ~/.sqldeveloper/jdk

要求輸入jdk路徑
/usr/java/jdk1.6.0_06

之后，終于看到sqldeveloper的啟動圖面。
