Logstash JDBC input Oracle settings


Hi there
I thought I would share my settings that I use to help save anyone else pulling their hair out :slight_smile:

jdbc {
      # The path to our downloaded jdbc driver saved mine in /bin, driver ojdbc6.jar also works. 
      #Best location can be /vendor folder
           jdbc_driver_library => "ojdbc7.jar"
      # ORACLE Driver Class
           jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
      # ORACLE jdbc connection string to our database, ORACLE  jdbc:oracle:thin:@hostname:PORT/SERVICE
           jdbc_connection_string => "jdbc:oracle:thin:@hostname:PORT/SERVICE"
    # The user and password we wish to execute our statement as
           jdbc_user => "DBUSERNAME"
           jdbc_password => "DBPASSWORD"
    # our SQL query
    statement => "select * from AWESOMETABLE"

    #optional extras I use 
      type => "Database"
      tags => ["awesome", "import"]

Hope that helps

Class loading failure with Logstash 2.1.0: oracle.sql.STRUCT

Hey thanks! This is not so straight forward for some settings especially the driver part. I want to ask have you got the timestamp to work on this setting? I have not been able to get timestamps to match. This is off topic so if you want just message me directly.


I can understand that it was not so easy to setup , I am using this to retrieve log files written by our web application import engine that go directly into Oracle. there are a few time stamps in this log that are not in a good ISO8601 format but I will be working on a Grok Pattern to take care of these.
Generally though I would try and do a grok pattern match or use Grok Debugger or Grok Matcher to test these http://grokconstructor.appspot.com/do/match

Yup I do the same thing. It matches as a grok pattern when I test just not while using logstash. Just a heads up if you see the error ruby and java string mismatch its because of the data type and you have to convert. I came across this problem earlier.

Hello, I get the error: cannot convert instance of class org.jruby.rubyobject to class java.lang.string. Any clue?

jdbc_connection_string => "jdbc:oracle:thin@//slcak349.us.oracle.com:15926:ems2971"

you have not used the right syntax for defining service it sholud be like

jdbc_connection_string => "jdbc:oracle:thin@//slcak349.us.oracle.com:15926/ems2971"
