One more thing to add. You need to configure health checks in the F5 for the midtier and arserver nodes. I have not fully vetted any of these approaches, but these are my thoughts:
ARS: 1. port check (this mostly works) 2. iRules in the F5 to simulate a session Midtier: 1. HTTP post to a page that the web server displays 2. HTTP post to a page that the servlet container renders (midtier config) 3. HTTP post to a page that the midtier renders (home page) 4. port check Axton Grams The opinions, statements, and/or suggested courses of action expressed in this E-mail do not necessarily reflect those of BMC Software, Inc.
