利用第二块网卡进行TimesTen的复制

    TimesTen的复制操作需要消耗大量的网络IO资源。如果Timesten复制和应用程序使用同一块网卡，则当系统压力加大时，这块可怜的网卡很容易成为整个系统的瓶颈。

    解决之道就是使用第二块网卡专门进行TimesTen的复制。方法是在建立active standby pair的时候指定要做复制的IP地址。

create active standby pair
     EPDSCP_BF_DS on "epdscp1", EPDSCP_BF_DS on "epdscp2" return twosafe
     store EPDSCP_BF_DS on "epdscp1"
         disable return all 1
         durable commit off
        resume return 0
        local commit action commit
         return services off when stopped
     store EPDSCP_BF_DS on "epdscp2"
        disable return all 1
        durable commit off
       resume return 0
        local commit action commit
        return services off when stopped
        route master EPDSCP_BF_DS on "epdscp1" subscriber EPDSCP_BF_DS on "epdscp2"
        masterip "10.10.10.1" priority 1 SUBSCRIBERIP "10.10.10.2" priority 1
        route master EPDSCP_BF_DS on "epdscp2" subscriber EPDSCP_BF_DS on "epdscp1"
        masterip "10.10.10.2" priority 1 SUBSCRIBERIP "10.10.10.1" priority 1;

其中EPDSCP1和EPDSCP2是主备机的主机名
