Java报表开发工具FineReport：[14]Oracle

1、实现思路将两台Oracle数据库中，配置相同的数据库以及数据库登录的用户名和密码，然后通过配置url让这个数据连接能连接两台机器，即使用一个数据连接连多个数据库。

2、实现步骤若使用Oracle数据库，在定义数据连接时，将原来的url改成：jdbc:oracle:thin:@(DESCRIPTION 租涫疼迟=(ADDRESS = (PROTOCOL = TCP)(HOST =IP1)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST =IP2)(PORT = 1521))(LOAD_BALANCE=yes)(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = 数据库名)))如：在168和170机器上都拥有数据库名为orcl10g，那么数据连接的url就改成：jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.100.168)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.100.170)(PORT = 1521))(LOAD_BALANCE=yes)(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl10g)))，即可。
