Workflow / Workspace Repair or Platform Migration Assistant

[mwiegand]

Good morning,

I frequently run into issues causes by Windows limitations like file path length warnings / errors. This time, because a Windows Updated again messed things up, I ran into user rights / permissions issues.

Using cmd and running the following command as admin ICACLS * /T /Q /C /RESET highlighted the aforementioned path lenght issues but also brought some files from another OS (Macs hidden files starting with a dot) to surface.

Documents\Knime-Workspace\Customers\FOLDERXYZ\FOLDERXYZ\.Data Harmonization (Auto-Save Copy - 2018-10-19 15-45) (Auto-Save Copy - 2018-10-25 11-37).autoSave\Magic (#777)\Loop End _Column Append_ (#657)\port_1\r0\r0\r0\r1\data.zip: The system cannot find the path specified.

Sometimes Knime creates extremly long path containing dozen of folders like "\r0\r0\r0".

Now, it is not quite clear if these errors can be savely ignored or not. Having a process in place to verify workspace or workflow integrity which could also get executed manually on demand, respectively a process to cater for platform changes, might be useful or at least reassuring that everything is ok.

Though, when a platform change happens i.e. because of restore / recovery, like when paths change from “/” to "" or from “C:” to “/”, it would be great to to not have to re-execute all workflows but execute whatever process to keep all results.

Maybe I am wrong here and there are already background processes in place.

Best
Mike

Hi @Mark_Carlson,

I have recently found a possible approach to this conundrum while working on this:

Workflow to ease collecting debug information

Hi, most Knime users that re struggling with challenging issues have yet not the know to collect debug information. For a long time, ever since @AnotherFraudUser created the replacement in AF Utilities (I cannot thank him enough!), I had the idea to provide a workflow which automatically collects as much as possible. I have taken an opportunity to create an initial draft I’d like to share and hope we can extend it as much as possible. Thanks in advance to all who contribute. About the workflo…

There are nodes available which allow to list all installed extensions.

Node List Extractor

Furthermore, I managed to list all extensions similar to a workflow from @AlexanderFillbrunn

List Extensions – alexanderfillbrunn

Since the information gathering is possible, the question is how to easily make all missing extensions get installed. That leads me to this:

Installing and Updating Extensions from the Command Line

I still got to find the time to think this through.

Cheers,
Mike
