How many keepalives may be lost before the connection is considered dead. A value of 0 uses the system default. If TCP_KEEPCNT is not supported, this parameter must be 0.

Use this parameter for all connections that are between a primary and mirror segment. Use tcp_keepalives_count for settings that are not between a primary and mirror segment.
