1. Client-side Connect Time Failover 在客户端的tnsname中配置多个地址,当用户连接时会按照次序尝试各个地址,直到连接成功,连接好后,不再检测地址是否可用,如果连接到的节点失败,则此session断开,必须用户重新连接。 2. TAF(Transparent Application Failover)在客户端指定该方式后,连接会自己检查,如果节点失败,会自...
三种Failover 之 Client-Side Connect time Failover、Client-Side TAF、Service-Side TAF 理论背景 Oracle RAC 同时具备HA(High Availiablity) 和LB(LoadBalance). 而其高可用性的基础就是Failover(故障转移). 它指集群中任何一个节点的故障都不会影响用户的使用,连接到故障节点的用户会被自动转移到健康节点,从...
In my simple scenario, I have one Primary Database (prima) and one Physical Standby Database (physt). After a switchover or after a failover, the primary is going to be physt. The challenge is now to get the connect from the client side to the right (primary) database. That is c...
散水的做法通常有砖铺散水,块石散水,混凝土散水等.混凝土散水每隔6—12m应设伸缩缝，与外墙之间留置沉降缝，缝内均应填充热沥青。
Re: Virtual connect failover time I checked my shared uplink set parameters and they're both "Linked-Active". I set my NICS to active-backup (Network Fault Tolerance), and when I updated the firmware in the VC units, I have lost my ssh connexion to one blade. Is that normal? ...
--connect_timeout_with_failover_secure_ms arg Connection timeout for selecting first healthy replica (for secure connections). Yes, it is caused by this. I changed this parameter to make it work: clusterA-ck01 :)setconnect_timeout_with_failover_ms = 1000;SET connect_timeout_with_failove...
@bgrainger No failover was happening at that time. It still looks like there is some connection leak happening given that we only have 8 threads and we always have them in the using block. We did not have any high traffic on the server, but somehow the pool is expanding and hitting th...
