I asked this question in the Tools General forum but received no response. Does anybody is this forum know how to resolve this problem? Here it is again with a bit more info:
When I ran sseutil -l, I discovered several databases that were still attached. However, they were old test projects that had previously been deleted. How do I detach them if they no longer exist? Using the detach command will not work because it just gives me a message: No valid database name matches the value specified.
