PI23292: ERROR 'CONNECTION RESET BY REMOTE HOST' ENCOUNTERED WHEN USING THE HTTP ADAPTER

APAR status

• Closed as program error.

Error description

• Error 'Connection reset by remote host' encountered when using
  the HTTP Adapter.
  

Local fix

• WTXCQ - WTX00045234
  GK / GK
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender HTTP adapter users that
  communicate with HTTP Servers that have a keep alive
  connectivity setting which is lower than the time it takes to
  complete a map run.
  
  Problem Description:
  WTX HTTP connections are being re-used within an existing map
  run after the Server's keep alive setting has expired.
  
  Platforms Affected:
  Windows
  

Problem conclusion

• Problem Conclusion:
  "-keepalive" connection option has been added to the HTTP
  adapter.  This setting prevents the HTTP adapter from re-using a
  connection after a specified amount of seconds has expired.
  The primary benefit of this capability is that it applies to
  connections established and re-used during an "active" map run.
  The "keepalive" setting also applies to "idle" or "inactive"
  connections, but the "IdleHTTP" option already performs this
  same task for "idle" or "inactive" connections.
  
  The "-keepalive" connection setting will NOT be shared with an
  adapter that has a different keepalive setting value or that has
  no keepalive setting defined.  Basically, a keepalive connection
  can be re-used with an adapter command line that includes the
  same setting and value (not to mention the same host and port
  settings).
  
  This connection comparison logic will enable different types of
  connections to the same host to be grouped together during
  re-use.  It will also prevent re-use of connections that behave
  with different keep alive settings.
  
  In effect, the "keepalive" setting gives a great degree of
  customized connection sharing capabilities at map run time,
  which in turn will provide the best level of compatibility with
  HTTP Server connection settings.
