-- Name: sp_MScleanupmergepublisher_internal
-- Description: This procedure currently performs the following function(s):
-- 1) Cleans up all the stale dynamic snapshot views
-- in all databases enabled for merge replication. This
-- procedure should normally be called at merge publisher startup.
-- Notes: 1)This procedure is enabled as a startup procedure when a database is
-- enabled as a first merge publisher database on the server and it
-- will be unmarked as a startup procedure when the last merge publisher
-- database is disabled.
-- 2)Errors within the SP are mostly ignored.
-- 3)This procedure can also be used by admins/securityadmins to perform
-- manual cleanup of all dynamic snapshot views. Note that cleaning up the
-- dynamic snapshot views can disrupt dynamic snapshots that are being generated.
-- Returns: (undefined)
-- Security: Only members of the sysadmin fixed server role can execute this
-- procedure successfully. So for this procedure to function proprely
-- as a startup procedure, the MSSQLServer service account must be a
-- member of the sysadmin role.
-- Requires Certificate signature for catalog access
