We had RAA 6.0.2 installed and we just upgraded it to 6.1. I also dropped the DB and recreated it.
I proceeded to collect inventory for a folder that has about 10 subfolders with about 20K files in all (9K copybooks in a copybooks folder).
However, it appears that the analysis stops on the Analyze File step and there are 14K outstanding requests listed. Also, no default concatenation set was created.
This is the first time I'm using 6.1 so I don't know if there is an issue or if it's just that it's been a while since I've run RAA and I missed some important step.
