DRM versions are deleted by DRM service restart, 11.2.21
Last week, we did a Backup to File from the Versions menu in our UAT environment, copied the file to our DEV server, and did a Restore from File in our DEV environment. Everything looked good. We had one warning, which I think is saying that user gio is not setup in DEV so the objects he owns will not be owned by him anymore.
User gio was not found while loading version Main_Version from file. Version/Hierarchy ownership and user-defined property values for this user will be ignored.
We have found that when we restart the DRM service, all our versions disappear from view. We have repeated this sequence. Do you know how to fix this or do we need to create a Service Request with Oracle Support?
