Prefreance while shipping LOG to Standby

Hi,

we are running primary database and 2 standby sites. one is ARCH SYNC and other one is LGWR ASYNC. ARCH site is used for reporting and testing purpose by opening it in R/W using flashback point.

and the second one is for Disaster Recivery Site. now there is often this hapend that network start problum and give connectivity error from primary and LGWR Site and there for a GAP becomes b/w primary and this site. and on the same time we just put back ARCH site to sync mode then there is also a gap b/w primary and ARCH site. now in this case out both sites are in GAP.
