Abstract
In a database, a high availability data replicator () synchronizes primary and secondary servers (). A smart large object application program interface () resides on the secondary server (). A cache module () creates a memory cache () corresponding to a smart large object responsive to a smart large object read operation requested by a client (). A smart large object read module () executes the read operation without acquiring a lock on the corresponding smart large object. An exception module () sends an exception to the client () responsive to a synchronizing event of the high availability data replicator () modifying said smart large object. On the primary server (), log entries of the modifying operation are ordered so that a log entry updating a large object header of said smart large object is consistent immediately upon execution on the secondary server ().
