 Nope. Abhiram?

Hi Anthony,

Sorry to grave dig but just wondered if you ever got an answer for this?

I am about to go down this rabbit hole myself as a customer wants a better
explanation (documentation) as to how this is supposed  to be configured
and how this should behave.

Cheers

Nick

There seems to be zero documentation for UCCX that mentions changing or
adding Data Source configuration in CUIC when running HA; whether HAoL or
HAoW.

However, I have heard from Cisco employees, forums posts, and colleagues,
these two points:

   1. The Data Source should point to the secondary node, and you have to
   manually change it, as the default is pointing to the primary node.

   2. The Data Source's Secondary tab is defaulted to disabled, and not
   populated.  It shouldn't be used, and CUIC takes care of updating the Data
   Source during a failure.

First off, where in the documentation is that explained?  I cannot find a
good explanation, sans ambiguity, to save my life.  Are people just
spreading rumors and old wives tales?

Also, I do know that back in the HRC days, the client would handle the
connection to the secondary server automatically.  So, I can see where this
tale comes from.

Now, with HAoW, I tested failover with the server shutdown.  Not in slave,
but actually powered off.  What I observed was, the Data Source was not
automatically updated, and I could run any reports, despite being logged in
to the secondary CUIC server.  The Data Source connection test failed,
obviously, and reports failed, obviously.

I did consider take a leap of faith and confiure the CUIC Data Source's
Secondary tab, but the user account to connect to the DB instance was not
in my control, and I don't know the password.  I'm sure I could get it, but
it was a show stopper nonetheless.

So, has anyone here actually tested with a failed node or island mode with
their HA setup, or is it all just speculation, like this post:
