kettle5.4ODBC和OCI连接配置

使用sqlplus 进一步测定发现数据库功能正常，尝试其他的连接方式。

2.尝试用ODBC的方式连接：

管理工具-->数据源--用户DSN--添加--选择oracle驱动

在kettle上配置ODBC连接 测试OK!

3.尝试OCI的连接方式报错如下：

错误连接数据库 [Source_Db] : org.pentaho.di.core.exception.KettleDatabaseException: 
        Error occurred while trying to connect to the database
        
        Error connecting to database: (using class oracle.jdbc.driver.OracleDriver)
        no ocijdbc11 in java.library.path

        主机名       : 
        端口           : 1521
        数据库名:orcl

4.google 了一下采取以下方案解决：

在环境变量中设置：

ORACLE_HOME=D:\app\gssjcj\product\11.2.0\dbhome_1
TNS_ADMIN=D:\app\gssjcj\product\11.2.0\dbhome_1\NETWORK\ADMIN
PATH=%ORACLE_HOME%\BIN;%PATH%

tnsnames.ora contains:
J3_CX =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 90.xx.xx.xx)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

Copied OCIJDBC11.dll to the libswt\win64

配置OCI连接：

测试OK！

之后在http://community.pentaho.com/看到如下描述：

OCI

OCI uses the Oracle client installed on the client you‘re currently using. If you are using OCI and an Oracle Net8 client, the JDBC driver version used in Kettle needs to match your Oracle client version. PDI 2.5.0 shipped with version 10.1, 3.0.0 ships with version 10.2. You can either install that version of the Oracle client or change the JDBC driver in PDI if versions don‘t match up.

This is how you change the Oracle JDBC driver in Kettle. Replace files "ojdbc14.jar" and "orai18n.jar" in the directory libext/JDBC of your distribution with the files found in the $ORACLE_HOME/jdbc directory on your server or if the versions are different, with the JDBC driver that matches your Net8 client. For Oracle 11g the drivers are named ojdbc5.jar and ojdbc6.jar.

If you still have issues please remember that the DLL that Oracle uses to connect has to be in your path. If all else fails, try copying the ocijdbc10.dll (might be called different in different versions) to the libswt/win32 folder (or win64).

RAC (Real Application Cluster)

When dealing with a Real Application Cluster or other complex failover oracle situations, please define the connection like this:

·         * Set to native (JDBC) connection type

·         * Leave hostname and port empty (this is also working with a port setting of -1)

·         * Set the database name to something like this...
(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = host1-vip)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = host2-vip)(PORT = 1521))(LOAD_BALANCE = yes)(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = db-service)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))

or (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=PRIMARY_NODE_HOSTNAME)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=SECONDARY_NODE_HOSTNAME)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=DATABASE_SERVICENAME)))

or (DESCRIPTION=(FAILOVER=ON)(ADDRESS_LIST=(LOAD_BALANCE=ON)(ADDRESS=(PROTOCOL=TCP)(HOST=xxxxx)(PORT=1526))(ADDRESS=(PROTOCOL=TCP)(HOST=xxxx)(PORT=1526)))(CONNECT_DATA=(SERVICE_NAME=somesid)))

Note: This does only work with a repository based system until 3.0.4. Beginning with 3.0.5 and 3.1 file based systems do also support this.
