This starts the syncing process against an existing subscription. The function
returns as soon as the request has been successfully sent. The synchronization will
take place in the background.  If the syncing process is already underway or if
the subscriber is already in sync and connected to the publisher this function has no effect.
If there is no connection to the publisher at the time of calling this function and the connection
fails an error is immediately signalled.
To initiate a syncronization the valid SQL account must be specified. Also the account must have rights to the publication unless publisher DBA@s account is used to connect.
