Error: oracle.jdbc.driver.OracleDriver not loaded.

[cinhtau]

Hi,

I'm working with the latest logstash v1.5.3 on a windows notebook. I installed the logstash-input-jdbc plugin successfully. I tried to perform a SQL connection test, but he is not able to load the Oracle jdbc driver.

My logstash config

input {
  jdbc {    
    jdbc_driver_library => "C:\Daten\tools\logstash-1.5.3\db\ojdbc6.jar"
    jdbc_driver_class => "oracle.jdbc.driver.OracleDriver"
    jdbc_connection_string => "jdbc:oracle:thin:@//localhost:1521/db"
    jdbc_user => "user"
    jdbc_password => "passwd"
    # will execute on the 0th minute of every hour every day
    schedule => "0 * * * *"
    statement => "select 1 from dual"
    jdbc_paging_enabled => "true"
    jdbc_page_size => "1"
  }
}
output {
    stdout { codec => rubydebug }
}

My setup from the windows cmd

C:\Daten\tools\logstash-1.5.3\db>dir
 Volume in drive C is SYSTEM
 Volume Serial Number is 8452-140B

Starting the test

C:\Daten\tools\logstash-1.5.3>bin\logstash.bat -f local-db.conf
io/console not supported; tty will not be manipulated
Error: oracle.jdbc.driver.OracleDriver not loaded. Are you sure you've included the correct jdbc driver in :jdbc_driver_
library?

I have checked the jar and database version. Using a java program and a sql client the connection was ok. Any ideas and pointers?

I run the debug trace

Error: oracle.jdbc.driver.OracleDriver not loaded. Are you sure you've included the correct jdbc driver in :jdbc_driver_library?
You may be interested in the '--configtest' flag which you can
use to validate logstash's configuration before you choose
to restart a running system.

Try to replace this line:
jdbc_driver_class => "oracle.jdbc.driver.OracleDriver"

for this one:
jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"

[cinhtau]

💥 Yeah, that works! Thx a lot. 👍 Somehow the docs didn't mentioned that. 😌

[pafq]

I know. Other user had the same problem (me included)

[blueskea]

Thank for pafq !

for those who are using mysql-connector-java-8.0.19.jar like connectors
use:
jdbc_connection_string => "jdbc:mysql://localhost:3306/db?serverTimezone=UTC"
jdbc_driver_class => "com.mysql.cj.jdbc.Driver"
