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...

When you connect to a conventional cluster, the client runtime also uses the address list when it tries to reestablish a connection to the message service: it attempts to connect to the brokers in the list until it finds (or fails to find) an available broker. If you specify only a sin...
Client-side configuration The client-side configuration for using dynamic failover is nearly identical to the client-side configuration for using static failover. The differences include: The failover URI can consist of a single broker URI. The updateURIsSupported option must be ...
Failover of existing connections is handled by TAF, which is controlled by the separate FAILOVER_MODE parameter. » The CONNECT_TIMEOUT parameter is the time to connect to the database instance providing the requested service, and includes the time to establish a TCP connection to the ...
If the availability group comes back online during a client application’s connection attempt but before the connect timeout period, the client driver may successfully connect during one of its internal retry attempts and no error will be surfaced to the application in this case.[Top]...
When the client runtime needs to establish or re-establish a connection to a message service, it attempts to connect to the brokers in the list until it finds (or fails to find) an available broker. If you specify only a single broker instance on the imqAddressList attribute, the ...
22.1.1. Failing Over During the Initial Connection Link kopieren Because the client does not receive information about every broker until after the first connection to the HA cluster, there is a window of time where the client can connect only to the broker included in the connection URL. Ther...
This is the action the client takes when the user is outside the corporate network. The options are: Connect—The client starts a VPN connection upon the detection of an untrusted network. Do Nothing—The client takes no action upon detection...
When operating over other types of network connections, Connect on Demand does not use TND to determine whether to connect a VPN. Is not a separate feature and cannot be configured or used outside the Connect-on-Demand capabili...
