Oracle Data Guard has several processes, on the primary database and standby databases, which communicate with each other over the network to manage redo transport and archiving. In certain failure situations, network hangs, disconnects, and disk I/O issues, these processes can hang potentially causing delays in redo transport and gap resolution. Oracle Data Guard has an internal mechanism to detect these hung processes and terminate them thus allowing the normal outage resolution to occur. You can now use two new parameters, DATA_GUARD_MAX_IO_TIME and DATA_GUARD_MAX_LONGIO_TIME, to tune waits times for a specific Oracle Data Guard configuration based on the user network and disk I/O behavior.
