Hi All,
We are parsing the data from Database columns using jbdc plugin in logstash , but for some of the records in the database it is showing below error in the log files.
scratching my head to solve this.

We have just migrated from the elk stack 5.5 to ELK stack 7.0.0 . We are not facing this issue in the lower version ( 5.5 ) but the same is not working in the 7.0.0 version.
We tried below things in the logstash configuration.
jdbc
{
jdbc\_connection\_string =\> "jdbc:oracle:thin:@DB\_IP:1521/dbName"
jdbc\_user =\> "SCHEMA\_NAME"
jdbc\_password =\> "PASSWORD"
jdbc\_driver\_library =\> "/opt/elk7/logstash-7.0.0/ojdbc/ojdbc7.jar"
jdbc\_driver\_class =\> "Java::oracle.jdbc.driver.OracleDriver"
columns\_charset =\> { "ENCODING" =\> "UTF-8" }
statement =\> "select \* from v\_wli\_qs\_report where localhost\_timestamp \>= (systimestamp - interval '0 00:15:00.0' day to second(1))"
}
What change we nned to perform in logstash configuration.
Any help would be appreciated .
Thanks in advance.
