For the last week, I have been trying to troubleshoot an issue we are having with our ER Studio Data Architecture version 17. We are unable to check in any diagrams/data dictionaries and we are getting a Repository Merge error, operation halting. (Id=3). In the repo_merge_error document, we are seeing this.
Missing Node Exception - occurs when diagram node cannot look up a parent node
Missing Parent GUID: 197027ef240f4f01bb24a7c27eb43edbChild Section ID: DIAGRAM (-1)Child GUID:
Does anyone have any idea what to look for or what needs to be done? I opened a ticket with Idera but they have yet to respond to me.
We have an automated process that checks in the data dictionary after adding objects, etc. My gut feeling is one of these objects corrupted the data dictionary. Is there a way to make the repository think a certain version of the data dictionary is the most current and load it all from there? I can see a version number for what I would like it back to but don't know if I can restore the file to that version. Unfortunately the compare and merge doesn't work because it is a model with only 2 data dictionaries and I don't think we can do a compare and merge on a data dictionary.
