[tao-users] Naming Service and multiple network adapters

[Phil Mesnier]

Hi Andriy,

Coincidentally, I've been working on solving a similar problem on OCI's branch of TAO. I haven't merged this into the trunk yet, probably after the next micro release. This new feature works with the IOR Table to refresh endpoint lists as the IORs are delivered to clients. How is your name service configured?

What version of TAO are you using?
