Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Provide an option to use hostname in * * Interoperable Object Reference (IOR) * * for RMI-IIOP communicaton * **************************************************************** * RECOMMENDATION: * **************************************************************** 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.
