15 Limitations of Cold Failover (MC/ServiceGuard) Scalability of cluster is limited to scalability of one server Cold failover is slow, as many time consuming tasks must be performed as part of failover moving and mounting logical volumes starting the oracle instance opening the data files After failover, all sessions must re-establish connections to the database After failover, the instance caches are cold introducing a performance brownout ctc_update ppt Page 15
