PM97829: UNABLE TO REMOTELY CONNECT TO THE WTX LAUNCHER AGENT USING AN IPV6 ADDRESS

APAR status

• Closed as program error.

Error description

• Unable to remotely connect to the WTX Launcher Agent using an
  IPv6 address.  The Launcher Agent is binding to the IPv6
  address (if present) which prevents using an IPv4 address when
  needed.
  
  The problem typically occurs when using the WTX Launcher Agent
  on a Windows 2008 or Windows 7 machine where an IPv6 address is
  enabled but the network does not support routing for IPv6
  addresses.
  

Local fix

• WTXCQ - WTX00043550
  GM / GM
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender Event Agent customers that
  only route IPv4-based addresses while operating on IPv6-enabled
  machines.
  
  Problem Description:
  The Event Agent is unable to force communication over an IPV4
  network address.
  
  Platforms Affected:
  All
  

Problem conclusion

• The Launcher Agent is able to operate purely in IPv4 mode.
  Before this fix, if a network environment was only configured to
   route IPv4 addresses, the Launcher Agent could not be reached
  over the network, since it would successfully bind with the
  local Window's ipv6 address before attempting to try and bind
  with an ipv4 address.  With this fix, the customer can set the
  following environment variable to ensure that the Launcher Agent
   defaults to binding to an IPv4 address:
  set WTX_LA_IPV4_ONLY=1
  
  Delivered in:
  8.3.0.6, 8.4.0.5, 8.4.1.1
