OA59039: DATA STREAMER DOESN'T CLOSE A CONNECTION WHEN LOGSTAH ENDS BECAUSE OF INACTIVIY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Data Streamer does not acknowledge connection close requests
  from TCP based subscribers.
  

Local fix

• BYPASS/CIRCUMVENTION:
  1-Enable the parameter tcp_keep_alive in your Logstash pipeline
  configuration file (input sub-section) . Below is an example I
  tested in my env:
  input {
     tcp {
     host => "xxxx.xxxx.xxxx.xxxx"
     port => pppp1
     tcp_keep_alive => true
     codec => multiline {
     pattern => "^\{"
     negate => true
     what   => "previous"
     max_lines => 1000
  }
  }
  Such parameter allows Logstash to keep the connection opened and
  so prevent the timeout of the session because inactivity

  When the Data Streamer receives a request to close the current
  connection to the subscriber, the Data Streamer does not
  promptly close the connection.
