I would like to know How and why to use WinDU and WinRU? I understand you would want to use it before an upgrade, but how about monthly maintenance? I would think that it does a great job of scanning the system and looking for issues. I looked for some decent how-to's but didn't find any. Using it is not rocket science at all. What I really am after here is a good explanation of the use cases and then after it is ran do I then execute WinRU? Do I run it on each node of the instance if it is a clustered install or is it ran once for the whole system?
Thanks for the response in advance,
In case you haven't seen it, there is PTC documentation available for both WinDU and WinRU. The Windchill Diagnostic Utility Guide describes how to use WindDU and provides reference information for each available task. The list of tasks also specifies when it is necessary to run WinRU.
