Rename DUAS without having to reinstall

[Angus Reid]

Dollar Universe 6.10.01 Windows 2012 R2

This question has been asked before but on earlier versions of Dollar Universe 6.

On v 6.10 there is no longer a license tied to a node name so that is not  blocker on renaming a node. It would be useful to be able to rename nodes to organise the system without the need to uninstall and reinstall a perfectly good running node.

Is this possible?

Many people have asked for this - us included. There should be a way to rename or reinitialize a node without reinstalling. 

[Adrian Fresno Menendez]

Hello, for reinitializing a node, one can always reinitialize the production data files and that would do.

For renaming a new node, the only thing that is available is the command unirefactorinst but this command is to be used only when the node has not yet had objects created, like during VM instanciation.

Please note that Dollar Universe is a non centralized solution, so the node name is referenced on ALL other nodes declared on the same UVMS, and this node_id is the key for referencing the node, so if a node name changes, its node id changes in consequence, so all references to this node id on ALL data files for all the areas for all nodes in the same UVMS needs to have this node id replaced with the newer one, hence why this is not at all a **** operation neither advised and thus why it was never implemented.

It can definitely cause much more harm and time to recover from a situation like that, than simply doing a  uniexp and exporting all the objects of the current node, then modifying the target mu node in the xml and then importing this modified xml referencing the new node into the newly installed node.

Thanks,

Adrian

Agree with Adrian on this one, it seems possible to change the name on a node and with a bit of effort it was possible to clone a node with a different name from a backup (this required a basic node on the same server then putting a modified backup on top of that). 

Although it was a success there were still wee bits of the original node lying around which didn't effect the functionality were still present.  Bit like putting down your own lino in a kitchen and the pattern doesn't match in a small corner, it looks l=fine but you will always be looking at the corner bit and wondering.

What was done instead was take advantage of DUAS packages and Node packages so it was possible to extract all of the objects easily. A new node with ther required name was installed then all the objects were deployed post. Small amount of effort to fi up the security (system user patterns, node views etc) and every thing up an running in about an hour and was a perfect install. 

The clone/renaming method took best part of a day and still had that misaligned corner. The rename node seems a bit of a false economy.

On a side note it is possible to install multiple nodes onthe same server so it is possible to parallel run using the old node until the new one is ready.
