Syntax

-- Name: sp_MSchangedynsnaplocationatdistributor

-- Description: This function is called by sp_MSrefreshdynamicsnapshotlocations
--              at the publisher to change the dynamic snapshot location command line
--              parameter value in an existing dynamic snapshot job

-- Returns: 0 - succeeded
--          1 - failed

-- Security: Only members of the 'sysadmin' server role and members of the
--           'db_owner' database role at the distributor can call this
--           procedure. This procedure is intended to be called through
--           the distributor_admin remote login in the case where
--           the distributor is a different machine from the publisher.
