pubList   A string containing a comma-separated list of publications to check. An empty string (the UL_SYNC_ALL macro) implies all tables except tables marked as no sync. A string containing just an asterisk (the UL_SYNC_ALL_PUBS macro) implies that all tables referred to in any publication. Some tables may not be part of any publication and are not included if this value is *.

threshold   The maximum number of rows to count, limiting the amount of time taken by the call. A threshold of 0 corresponds to no limit (all rows that need to be synchronized are counted). A threshold of 1 can be used to quickly determine if any rows need to be synchronized.
