Properties

CacheNames

Gets or sets cache names this sender hub works with. All sender hubs working with concrete cache must have this property equal. E.g., in case one sender hub works with caches A and B, then another sender hub cannot work with caches B and C. Instead, both sender hubs must work with either {A, B}, {B, C} or even {A, B, C} caches. However, it is possible for the first sender hub work with caches {A, B} and for the second sender hub to work with caches {C, D}.

Declaration

public ICollection<string> CacheNames { get; set; }

Property Value

Type	Description
ICollection<System.String>	Cache names this sender hub works with.

ConnectionConfiguration

Gets or sets remote data center connection configurations. Defines data centers this sender hubs will work with.

Declaration

public ICollection<DrSenderConnectionConfiguration> ConnectionConfiguration { get; set; }

Property Value

Type	Description
ICollection<DrSenderConnectionConfiguration>	Remote data center connection configurations.

HealthCheckFrequency

Gets or sets health check frequency. Defines how often an attempt to restore connection to disconnected receiver hubs is performed and how often connected receiver hubs will be checked for necessity to send a ping request using ReadTimeout property.

Declaration

public TimeSpan HealthCheckFrequency { get; set; }

Property Value

Type	Description
TimeSpan	Health check frequency.

MaxErrors

Gets or sets maximum amount of sequential errors in receiver hub responses. When this threshold is reached, connection to this faulty receiver hub will be closed and reciver hub will be considered offline. Further attempts to re-establish connection to this receiver hub will be performed according to ReconnectOnFailureTimeout property.

Declaration

public int MaxErrors { get; set; }

Property Value

Type	Description
System.Int32	Maximum amount of sequential errors in receiver hub responses

MaxFailedConnectAttempts

Gets or sets maximum failed connect attempts. Once amount of failed sequential attempts to connect to particular remote receiver hubs exceeds this limit, receiver hub will be considered offline. Further attempts to re-establish connection to this receiver hub will be performed according to ReconnectOnFailureTimeout property.

Declaration

public int MaxFailedConnectAttempts { get; set; }

Property Value

Type	Description
System.Int32	Maximum failed connect attempts.

MaxQueueSize

Gets or sets maximum wait queue size. Defines maximum amount of entries which are read from store but have not been acknowledged yet.

Declaration

public int MaxQueueSize { get; set; }

Property Value

Type	Description
System.Int32	Maximum wait queue size.

ReadTimeout

Gets or sets read timeout. When difference between current time and the time when last read operation on particular remote receiver hub occurred is greater than this timeout, ping request will be sent to this receiver hub.

Declaration

public TimeSpan ReadTimeout { get; set; }

Property Value

Type	Description
TimeSpan	Read timeout.

ReconnectOnFailureTimeout

Gets or sets reconnect-on-failure timeout. This values defines timeout after which connection to remote receiver hub can be re-established in case it was previously disconnected due to a failure.

Declaration

public TimeSpan ReconnectOnFailureTimeout { get; set; }

Property Value

Type	Description
TimeSpan	Reconnect-on-failure timeout.

SenderGroups

Gets or sets sender groups this sender hub will participate in. If DrUseCacheNames is true then DR will ignore sender groups and fallback to old behaviour. If not set then default one will be used.

Declaration

public ICollection<string> SenderGroups { get; set; }

Property Value

Type	Description
ICollection<System.String>	Group names this sender hub will participate in.

SocketReceiveBufferSize

Gets or sets socket receive buffer size in bytes. Will be applied to all remote connections.

Defaults to 0, which means that OS default value will be used.

Declaration

public int SocketReceiveBufferSize { get; set; }

Property Value

Type	Description
System.Int32	Socket receive buffer size in bytes.

SocketSendBufferSize

Gets or sets socket send buffer size in bytes. Will be applied to all remote connections.

Defaults to 0, which means that OS default value will be used.

Declaration

public int SocketSendBufferSize { get; set; }

Property Value

Type	Description
System.Int32	Socket send buffer size in bytes.

SystemRequestTimeout

Gets or sets system request timeout. Sender hub processor performs two types of system requests: handshake and ping. Handshake request contains information required by receiver hub and is only sent when network connection is established. Ping request just checks that receiver hub is reachable and responds when there was no reads from it for more than ReadTimeout.

In case any of these two requests was sent to receiver hub and there is no response for too long, it indicates a problem with either network connectivity or receiver hub itself. Thus, when the given timeout is exceeded, connection to receiver hub is closed.

Declaration

public TimeSpan SystemRequestTimeout { get; set; }

Property Value

Type	Description
TimeSpan	System request timeout.
