Are There Existing Steps to Unregister an Application and then Re-Register It?

One answer

I'm using IHS and the IHS plugin for WAS in front of RS (and all other apps).
1. RB setup problem
To fix this I had to add following in httpd.conf:
(same fixed another issue in RQM)
#gus begin
# Fix for: QM ETL Job fails with 401 or 403 error when using HTTP Proxy and OAuth authentication
# http://www-01.ibm.com/support/docview.wss?uid=swg21632841
SetEnv websphere-nocanon 1
#gus
2. Re-registration problem
re-registration should work with setup.
But be sure you have all consumer and friends removed. What I also did was deinstall RB with Install Manager and install it again, before run setup. Additionally I also stopped the profile where RB is running in, and cleared temp and wstemp.
BTW. why deregister DCC and LQE? RB is a separate story and must not be handled with the others. It can also reside in it's own profile if you like. No clue why IBM is bundling it with the others to JRS. Does not make really sense, because the others are datacollectors and RB is an enduser application.
hope this helps

Thanks for the response Guido. I forgot to mention that I am still using Tomcat and have not migrated over to Websphere yet. It looks like you went with the extra step of uninstalling RS, DCC and LQE and then re-installing. I was hoping to not have to go to that level but maybe I do. I've already done that on a production system where I moved all of the reporting apps (RS, DCC and LQE) off of the Jazz server and on to a separate server as recommended by IBM, but I am still unable to register RS again. I have PMR out there but still waiting to get some answers as to why.
In regards to this set up though, all I am really trying to is get it working in this test environment and not having any luck. I think my next step will be to go through, make sure and verify all of the apps (RS, DCC and LQE) are all unregistered and no friendships then uninstall the app using IM. Then reinstall and try again. If that fails ....
