Starting with Java™ 1.4.1, the IP address is not cached by default. This can cause delays and performance degradation if the application relies on this caching mechanism, since a lookup is now performed each time.
The WebSphere Application Server runtime code calls the InetAddress.getLocalHost() method in several places which then causes the DNS lookup requests. Applications making outbound calls would also trigger DNS lookup requests
There is, of course, a solution to this IF it becomes a problem.
There is a JVM setting - com.ibm.cacheLocalHost=true - that can be set, and the Technote shows how to set it for Deployment Manager, Node Agent, server instances etc.
Of course, one would always do this via a script :-)

IBM BPM Advanced 8.5.5 - Process Center to Process Server
Fri, Dec 5th 2014 3:05a Dave Hay So I am continuing to get my head around the integration between Process Center and Process Server, in that it's possible to have a connected Process Server to which one can actively deploy snapshots, using the so-called online/connected deployment.This is what the connected Process Server looks like: -Whilst this is easy to configure when one first creates a Deployment Environment, I had a situation recently where one of our team inadvertently clicked the Take Server Offline button.This does p [read] Keywords: ibm
