Databases do not appear after unpacking a site
When you unpack a site on Computer A, and you create the databases for resources on Computer B, after you have finished unpacking the site, the new databases do not appear on Computer B.
Solution
Wait several minutes. Site Packager runs on Computer A, so if network congestion exists, there could be a delay before the resources are created. Also, you can run Commerce Server Site Packager again to make sure you have created the databases on Computer B, and not on Computer A.
