Flow control for shared-disk secondary servers

Flow control provides a way to limit log activity on the primary server so that shared-disk (SD) secondary servers in the cluster do not fall too far behind on processing transactions.

Set the SDS_FLOW_CONTROL configuration parameter on the primary server to enable flow control. All SD secondary servers in the cluster are affected by the primary server's SDS_FLOW_CONTROL configuration parameter setting. When flow control is active, users connected to the primary server may experience slower response time.

Logs are always sent to the SD secondary server in the order in which they were received.
