Hi Folks,

I am trying to push data from oracle to ES or rabbitmq and I am able to do that as well. My problem when I am pushing those data and that time my ES or rabbitmq goes down then I am not able to figure out that from where I need to push that data because my last\_run\_metadata file also gets updated.

```
input {
jdbc{
 jdbc_validate_connection => true
 jdbc_driver_library => ""
 jdbc_driver_class => "Java::oracle.jdbc.OracleDriver"
 jdbc_connection_string => "myconnectionstring"
 jdbc_user => "username"
 jdbc_password => "password"
 statement => "SELECT * FROM auto_increment_tb where id>:sql_last_value"
 use_column_value=>true
 tracking_column=>id
 schedule => "* * * * * *"
 last_run_metadata_path => "C:\Pramod\rnd\ElasticSearch\logstash-7.2.0\.logstash_jdbc_last_run"
}

```

}  
output {  
elasticsearch {  
hosts =\> ["[http://localhost:9200](http://localhost:9200)"]  
index =\> "auto\_increment\_tb"  
}  
stdout{  
codec =\> rubydebug  
}  
}

I just want that is there any method or something so that I can update my last\_run\_metadata file on a conditional basis or is there any better solution?

Pls help.
