I have installed Sitecore 9 update 1 in my local machine . When I try to rebuild the link database for the vanilla installation, the rebuilding keeps on processing and will never complete.
When I see the sitecore log file, there is below exception and nothing else.
Exception: Sitecore.XConnect.XdbCollectionUnavailableException Message: An error occurred while sending the request. Source: Sitecore.Xdb.Common.Web Nested Exception Exception : The certificate was not found. Source: Sitecore.Xdb.Common.Web
Is rebuilding the link database related to xConnect ?
Is it mandatory to use xConnect in Sitecore 9?
How can I rebuild the link database without xConnect?
