用kettle新建DB连接的时候总是报错，可是用plsql连接是可以连上，错误信息大致如下：

主机名       : 10.9.202.67
端口           : 1521
数据库名:ORCL

查找资料得知：

jdbc连接数据库的时候，需要使用数据库的sid_name，而不是数据库的services_name
而使用plsql连接数据库的时候，只需要数据库的services_name即可，所以修改连接字符串中的services_name （即连接参数中的database name）为sid_name

PS：查看数据库的sid_name语句：

select INSTANCE_NAME from v$instance;
