PH18052: ADD AN OPTION TO USE HOSTNAME IN ORB IOR

9.0.5.3: WebSphere Application Server traditional Version 9.0.5 Fix Pack 3

APAR status

• Closed as program error.

Error description

• If you use hostname in the ORB IOR there would be error in ORB
  communication. The option is to add the function in Liberty to
  use hostname in the IOR so it could be resolved properly.
  

Local fix

• N/A

  ****************************************************************
  In a network environment where external network and intranet
  has different set of ip addresses assigned for a same server,
  an ORB request may fail due to ip address resolution.
  For example, a server is assigned with two addresses 172.x.y.z
  for external network, and 52.a.b.c for intranet with the same
  hostname such as "sampleHost.ibm.com",  the ORB request
  to/from this server may fail because WebSphere's ORB requests
  use ip address in its IOR by default.  Depending on where the
  request is handled, the ip address in the IOR may or may not
  be resolved by DNS.
  If IOR had hostname, it would have been resolved by both
  intranet and external network.
  

Problem conclusion

• A custom property is introduced to make WebSphere use
  hostname in IOR instead of ip address.
  
  When the following custom property is set to true,
  com.ibm.websphere.security.ior.hostName
  WebSphere will set hostname in the IOR.  The default value for
  this property is false.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.17 and 9.0.5.3.  For more information, see 'Recommended
