#Dbvisualizer connect to sql server driver

Increasing connection timeout and implementing connection retry logic will increase the probability that an application will connect to an availability group. Rest of the connection attempts follow the same logic as in the multiSubnetFailover feature.

When transparentNetworkIPResolution is true, the first connection attempt uses a timeout value of 500 ms.

transparentNetworkIPResolution is ignored if there are more than 64 IP addresses.

transparentNetworkIPResolution is ignored if database mirroring is used.

transparentNetworkIPResolution is ignored if multiSubnetFailover is true.

transparentNetworkIPResolution is true by default.

#Dbvisualizer connect to sql server driver

If the first attempt fails, the driver tries to connect to all IP addresses in parallel until the timeout expires, discarding any pending connection attempts when one of them succeeds. When transparentNetworkIPResolution is true, the driver attempts to connect to the first IP address available. For more details, see the sections below.Р”В«eginning in version 6.0 of the Microsoft JDBC Driver for SQL Server, a new connection property transparentNetworkIPResolution (TNIR) is added for transparent connection to Always On availability groups or to a server that has multiple IP addresses associated. Use applicationIntent to declare the application workload type.

Specify multiSubnetFailover=true when connecting to the availability group listener of an availability group or a Failover Cluster Instance. The following connection properties were added in Microsoft JDBC Driver 4.0 for SQL Server:

If a Microsoft JDBC Driver for SQL Server application is connected to an AlwaysOn database that fails over, the original connection is broken, and the application must open a new connection to continue work after the failover. For more information about AlwaysOn Availability Groups, see SQL Server 2012 (11.x) Books Online.Р”В«eginning in version 4.0 of the Microsoft JDBC Driver for SQL Server, you can specify the availability group listener of a (high-availability, disaster-recovery) availability group (AG) in the connection property. This article discusses Microsoft JDBC Driver for SQL Server support for high-availability, disaster recovery: AlwaysOn Availability Groups.
