View Availability Replica Properties (SQL Server)
This topic describes how to view the properties of an availability replica for an AlwaysOn availability group by using SQL Server Management Studio or Transact-SQL in SQL Server 2012.
To view and change properties an availability replica
In Object Explorer, connect to the server instance that hosts the primary replica, and expand the server tree.
AlwaysOn High Availability node and the Availability Groups node.
Expand the availability group to which the availability replica belongs, and expand the
Availability Replicas node.
Right-click the availability replica whose properties you want to view, and select the
Availability Replica Properties dialog box, use the General page to view the properties of this replica. If you are connected to the primary replica, you can change the following properties: availability mode, failover mode, connection access for the primary role, read-access for the secondary role (readable-secondary), and the session-timeout value. For more information, see . Availability Replica Properties (General Page)
To view properties and states of availability replicas
To view the properties and states of availability replicas, use the following views and system function:
Returns a row for every availability replica in each availability group for which the local instance of SQL Server hosts an availability replica.
Column names: replica_id, group_id, replica_metadata_id, replica_server_name, owner_sid, endpoint_url, availability_mode, availability_mode_desc, failover_mode, failover_mode_desc, session_timeout, primary_role_allow_connections, primary_role_allow_connections_desc, secondary_role_allow_connections, secondary_role_allow_connections_desc, create_date, modify_date, backup_priority, read_only_routing_url
Returns a row for the read only routing list of each availability replica in an AlwaysOn availability group in the WSFC failover cluster.
Column names: replica_id, routing_priority, read_only_replica_id
Returns a row for every availability replica (regardless of join state) of the AlwaysOn availability groups in the Windows Server Failover Clustering (WSFC) cluster.
Column names: group_name, replica_server_name, node_name
Returns a row for each replica (regardless of join state) of all AlwaysOn availability groups (regardless of replica location) in the Windows Server Failover Clustering (WSFC) cluster.
Column names: replica_id, replica_server_name, group_id, join_state, join_state_desc
Returns a row showing the state of each local availability replica and a row for each remote availability replica in the same availability group.
Column names: replica_id, group_id, is_local, role, role_desc, operational_state, operational_state_desc, connected_state, connected_state_desc, recovery_health, recovery_health_desc, synchronization_health, synchronization_health_desc, last_connect_error_number, last_connect_error_description, and last_connect_error_timestamp
Determines whether the current replica is the preferred backup replica. Returns 1 if the database on the current server instance is the preferred replica. Otherwise, it returns 0.
