配置 Pentaho 数据集成以连接到 Oracle DB

Question

I have configured Oracle VirtualBox with DB, user and populated a small DB. In the same machine I've installed Pentaho Data-Integration(Spoon), the JDBC driver and I'm trying to create a connection to Oracle DB but without success. This is where I'm typing the credentials/data:

Host Name : localhost

Database Name : (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=ORCL)))

Port Number : 1521

User Name : SYSTEM

Password : oracle

This is the error message:

Error connecting to database [oraConn12c] : org.pentaho.di.core.exception.KettleDatabaseException:

How can I configure it in order to connect Pentaho/Spoon to the Oracle DB? The oracle DB seems to be working fine, I've also tried with other users/databases that I created, but the result is the same.

Answer 1

I was able to resolve this same issue by removing 'Host Name' and 'Port Number' details from the connection window. Leaving only the 'DB Name' string.

Answer 2

I had a similar issue. Could solve it that way for the client tool, but not for the carte server.

I fixed it with an JNDI connection.

put this in your pdi\\simple-jdni\\jdbc.properties

mydb/type=javax.sql.DataSource
mydb/driver=oracle.jdbc.driver.OracleDriver
mydb/url=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS(PROTOCOL=TCP)(HOST=myhost)(PORT=myport)))(CONNECT_DATA=(SERVICE_NAME=myservicename)))
mydb/user=myuser
mydb/password=mypassword

and this connection in your repositories.xml:

<connection>
<name>JNDI</name>
<server>myserver</server>
<type>ORACLE</type>
<access>JNDI</access>
<database>mydb</database>
<port>myport</port>
<username>myuser</username>
<password>mypassword</password>
<servername/>
<data_tablespace/>
<index_tablespace/>

Answer 3

Adding

(FAILOVER_MODE=(type=select)(method=basic)(retries=20)(delay=3))))

to the end of the string solved it for us.
