KettleDataBaseException ,ETL连接数据库失败ora-12505解决方法

问题描述：
数据库迁移之后，ETL(数据同步工具)工具连接oracle时,选用jdbc 连oracle数据库的时候出现了ora-12505错误：

错误如下：

数据库 [orcl] : org.pentaho.di.core.exception.KettleDatabaseException: 

Error occured while trying to connect to the database

Error connecting to database: (using class oracle.jdbc.driver.OracleDriver)

Listener refused the connection with the following error:

ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

The Connection descriptor used by the client was:

10.10.88.90:1521:DBDMS

而直接通过plsql可以正常连接数据库,或者可以通过sqlplus 连接数据库

经过debug和查找相关的资料发现问题原因如下：

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

附：

查看数据库中当前的sid:

SQL> select INSTANCE_NAME from v$instance;

INSTANCE_NAME
