Hi Anthony, Yup, unfortunately we don’t do a very good job of documenting this. Ideally, it should configure itself and the reason the secondary tab is not populated is that secondary tab is meant for standalone CUIC servers itself where each server needs to have a primary/backup, but in UCCX we don’t utilize that concept.
I have asked the team to create an external facing technotes covering this behavior and how the troubleshooting should be done. I will share the document here once it is done for review.

First, I was not in a situation where datasources were pointing at each other, I did have them pointing to a single node. And that's where failover failed me. I had both nodes pointing at the default Node 1, which was my Master, and when failover happened, reporting was down. 1) Where in the documentation does it say to reconfigure the datasource to point to the non-master node when deploying HA? 2) Why doesn't it configure itself? 3) Why doesn't it update itself like LiveData does? 4) Why can't we use the secondary source tab to populate both nodes? 5) What if I don't want all my reporting traffic traversing the WAN in HAoW deployments? I.e., My Mast is located where most of my Agent and Supervisors are, and I want reporting to stay local to them. The HA node is there just in case of a datacenter failure.

So, assume N1 is the master. CUIC on N1 should be pointing to N2 datasource host and CUIC on N2 should be pointing to N2 datasource host. Also, unlike older versions we don’t redirect users to the secondary UCCX IP to login to run reports. You can login to any node CUIC and run the report, but the datsource host should be the secondary server. However, we have seen cases where the nodes point to each other: N1 pointing to N2 (expected), N2 pointing to N1 (problem). This is opened as a defect and we are investigating why this can happen and I am guessing that’s what has happened in Anthony’s case in the original email thread. CSCvd22513 is the defectID for your reference. I will share more information on the outcome of the investigation. LiveData: This is always pointing to the local node by default and need not be changed. The LD datasource uses REST API to figure out the engine master and will obtain the feed from the current active server. The LD failover too should happen automatically. So if the engine failover happens and you are still logged into N1 (slave now), LD should still be available and usable.

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: https://supportforums.cisco.com/discussion/12473981/ha-uccx-cuic-data-only-one-server _______________________________________________ cisco-voip mailing list cisco-voip@puck.nether.net<mailto:cisco-voip@puck.nether.net> https://puck.nether.net/mailman/listinfo/cisco-voip -- - Nick
