	Defines the name of the System Property controlling the maximum time for connections to reconnect to the backup server during the fault-tolerant switch. This property is similar to PROP_CONNECT_ATTEMPTS_TIMEOUT. The difference is that it may be necessary to use different parameters during reconnect than during the initial connect. Initial connect of the clients to the server is normally distributed in time and there are less chances of the server exceeding its maximum accept queue. During fault-tolerant switch, all connected clients automatically try to reconnect to the backup server, approximately at the same time.

Detailed Description

Defines miscellaneous constants and provider properties used by TIBCO Enterprise Message Service

This class also provides methods for getting the size of a Message object and manipulating provider properties.

The static methods GetProperty and SetProperty can be use to override default properties by user

Member Function Documentation

static int TIBCO.EMS.Tibems.CalculateMessageSize ( Message  msg )

inlinestatic

Calculates and returns total size of the message wire representation.

The total size includes headers, properties and body.

This method re-measures the message, and caches the results; contrast Tibems.GetMessageSize.

This method might consume process storage, and might involve disk I/O - with associated performance penalties.

This method always creates internally the actual wire format of the message regardless of the state of the message.

Parameters

msg	Compute the size of this message.

Exceptions

ArgumentException	if parameter is null or is a foreign message implementation.
TIBCO.EMS.EMSException	if an error occurred while building message wire representation.

static Message TIBCO.EMS.Tibems.CreateFromBytes ( byte[]  bytes )

inlinestatic

Create a message from specified byte array

Specified byte array must be previously obtained using the GetAsBytes method. Created message is set to read-only state, use the MakeWriteable method to enable message modification without erasing its content.

Parameters

bytes

The byte array representation of the message. This byte array must be the result of previously calling GetAsBytes.

Returns

The message constructed from the byte array

static bool TIBCO.EMS.Tibems.GetAllowCallbackInClose ( )

inlinestatic

Deprecated, use Tibems.GetAllowCloseInCallback instead.

Deprecated:

Use Tibems.GetAllowCloseInCallback instead.

static bool TIBCO.EMS.Tibems.GetAllowCloseInCallback ( )

inlinestatic

Determine whether client callbacks may call close methods

According to the JMS specification, Close methods (that is, MessageConsumer.Close, Session.Close, Connection.Close) cannot return while any message callbacks (that is, EMSMessageHandler, IMessageListener.OnMessage) are running. As a result, a message callback must not call a Close method, lest it cause a deadlock. The SetAllowCloseInCallback method explicitly overrides this JMS requirement, permitting callbacks to call Close without deadlock (that is, embedded Close calls do not wait for callbacks to return).

This method returns, if it is allowed to call Close in callbacks.

static byte [] TIBCO.EMS.Tibems.GetAsBytes ( Message  message )

inlinestatic

Return a copy of the message data as a byte array, suitable for archiving in a file

To reconstruct the message from bytes use method createFromBytes. Parameter must be an instance of TIBCO Enterprise Message Service Message object.

Parameters

message

The source message with which to fill the byte array.

Returns

The byte array as a copy of the message.

static string TIBCO.EMS.Tibems.GetConnectAttempts ( )

inlinestatic

Returns the connect attempts setting.

This setting governs all client Connection objects as they attempt to connect to the server. Its value is a string of the form attempts or attempts,delay

• attempts limits the number of times that the connection object attempts to establish a connection to the server. When this property is absent, the default value is 2. The minimum value is 1.
• delay is the time (in milliseconds) between connection attempts. When absent, the default value is 500. The minimum value is 250.

Returns

The string argument to SetConnectAttempts, rather than the numeric value of the setting. If the client has not set a value, this method returns the null string.

static int TIBCO.EMS.Tibems.GetConnectAttemptTimeout ( )

inlinestatic

Returns the connect attempt timeout value

static String TIBCO.EMS.Tibems.GetConnectionActiveURL ( Connection  connection )

inlinestatic

Return the URL of the EMS server for the specified connection.

Parameters

connection

The connection to the EMS server.

Returns

The string representing the URL

static string TIBCO.EMS.Tibems.GetEncoding ( )

inlinestatic

Return the name of the global string encoding for messages

Programs can override the global encoding for individual messages. When neither a global nor an individual message encoding has been set, then EMS encodes the strings of an outbound message using the default UTF-8 encoding.

This encoding applies to all strings in message bodies (names and values), and properties (names and values). It does not apply to header names or values. The methods BytesMessage.ReadUTF and BytesMessage.WriteUTF are exempt from global and individual encoding settings.

Returns

The name of the encoding used for global string encoding for message, or null global encoding has not been set.

static bool TIBCO.EMS.Tibems.GetExceptionOnFTEvents ( )

inlinestatic

Returns if exception listener is called on disconnect and reconnect attempts.

static bool TIBCO.EMS.Tibems.GetExceptionOnFTSwitch ( )

inlinestatic

Return the fault tolerance exception setting

This setting determines exception behavior when the client successfully switches to a different server (fault-tolerant failover).

• When true, the connection's ExceptionListener catches an EMSException, which contains the name of the new server.
• When false, fault-tolerant failover does not trigger an exception in the client.

static int TIBCO.EMS.Tibems.GetMessageBodySize ( Message  msg )

inlinestatic

Returns the total wire size of the message body for a message which was received or sent.

The size is implicitly measured and cached when an inbound message arrives at the client, and when the client sends an outbound message. If the client modifies a message, or creates a message but never sends it, then this method could yield an incorrect cached value. To explicitly force a new measurement and cache its results, call Tibems.CalculateMessageSize; then the method yields the correct value.

If the body of the message is compressed, this method returns the size of the compressed wire representation.

Parameters

msg	The message for which to return the size of the message body.

Returns

The total size of the message body.

Exceptions

ArgumentException

if parameter is null or is a foreign message implementation.

static string TIBCO.EMS.Tibems.GetMessageEncoding ( Message  message )

inlinestatic

Return string encoding name set for this message

This encoding for an individual message overrides the global encoding. When neither a global nor an individual encoding has been set, then EMS encodes the strings of an outbound message using the default UTF-8 encoding.

This encoding applies to all strings in message bodies (names and values), and properties (names and values). It does not apply to header names nor values. The methods BytesMessage.ReadUTF and BytesMessage.WriteUTF are exempt from global and individual encoding settings.

Parameters

message

Get the encoding for this message.

Returns

The string encoding name for this message, or null is no encoding is set.

static int TIBCO.EMS.Tibems.GetMessageHeadersSize ( Message  msg )

inlinestatic

Returns the total wire size of the message headers for a message which was received or sent.

The size is implicitly measured and cached when an inbound message arrives at the client, and when the client sends an outbound message. If the client modifies a message, or creates a message but never sends it, then this method could yield an incorrect cached value. To explicitly force a new measurement and cache its results, call Tibems.CalculateMessageSize; then the method yields the correct value.

Parameters

msg	The message for which to return the size of the message headers.

Returns

The total size of the message headers.

Exceptions

ArgumentException

if parameter is null or is a foreign message implementation.

static int TIBCO.EMS.Tibems.GetMessagePropertiesSize ( Message  msg )

inlinestatic

Returns the total wire size of the message properties for a message which was received or sent.

The size is implicitly measured and cached when an inbound message arrives at the client, and when the client sends an outbound message. If the client modifies a message, or creates a message but never sends it, then this method could yield an incorrect cached value. To explicitly force a new measurement and cache its results, call Tibems.CalculateMessageSize; then the method yields the correct value.

Parameters

msg	The message for which to return the size of the message properties.

Returns

The total size of the message properties.

Exceptions

ArgumentException

if parameter is null or is a foreign message implementation.

static int TIBCO.EMS.Tibems.GetMessageSize ( Message  msg )

inlinestatic

Returns the total wire size of the message which was received or sent

GetMessageSize returns the total size of a message - that is, the number of bytes that traverse the network when the client sends the message. This total is slightly larger than the sum of its three constituent parts, because it includes additional control information. Furthermore, the server adds its own control information as well, so the size of message as measured by receivers is slightly larger than its size as measured by the sender.

The size is implicitly measured and cached when an inbound message arrives at the client, and when the client sends an outbound message. If the client modifies a message, or creates a message but never sends it, then this method could yield an incorrect cached value. To explicitly force a new measurement and cache its results, call Tibems.CalculateMessageSize; then the method yields the correct value.

Parameters

msg	The message for which to return the size.

Returns

The total wire size of the message.

Exceptions

ArgumentException

if parameter is null or is a foreign message implementation.

static string TIBCO.EMS.Tibems.GetMulticastDaemon ( )

inlinestatic

Get the port on which the EMS client will connect to the multicast daemon.

Deprecated:

As of release 8.3

static bool TIBCO.EMS.Tibems.GetMulticastEnabled ( )

inlinestatic

Get whether MessageConsumers subscribed to a multicast-enabled topic will receive messages over multicast.

Deprecated:

As of release 8.3

static int TIBCO.EMS.Tibems.GetNPSendCheckMode ( MessageProducer  producer )

inlinestatic

Return the mode defining when a producer checks the result of sending a NON_PERSISTENT message.

This method returns the send check mode previously set by {SetNPSendCheckMode} method. Notice that if the returned value is {NPSEND_CHECK_DEFAULT} then the effective mode can be set by the server parameter applied to all producers.

Parameters

producer

message producer, must not be null

Returns

one of constants {NPSEND_CHECK_DEFAULT}, {NPSEND_CHECK_ALWAYS}, {NPSEND_CHECK_NEVER}, {NPSEND_CHECK_TEMP_DEST}, {NPSEND_CHECK_AUTH} or {NPSEND_CHECK_TEMP_AUTH}

Exceptions

ArgumentException

if producer is null

SetNPSendCheckMode

static int TIBCO.EMS.Tibems.GetPingInterval ( )

inlinestatic

Return the ping interval in seconds used by inactive connections

Clients test network connectivity by sending ping requests to the server at regular intervals. This method returns that interval (in seconds). Zero is a special value that disables ping testing.

Returns

The ping interval in seconds

static object TIBCO.EMS.Tibems.GetProperty ( string  key )

inlinestatic

Retrieve the property value given the property name

The properties here refer to those explicitly set by calling SetProperty or system properties (e.g Tibems.PROP_PING_INTERVAL etc.) set by either calling the specific methods (e.g SetPingInterval) or system properties set via SetProperty.

You can supply any of the following constants:

• PROP_SOCKET_RECEIVE
• PROP_SOCKET_SEND
• PROP_CONNECT_ATTEMPTS
• PROP_RECONNECT_ATTEMPTS
• PROP_CLOSE_IN_CALLBACK
• PROP_PING_INTERVAL
• PROP_FT_SWITCH_EXCEPTION
• PROP_MESSAGE_ENCODING
• PROP_DAEMON_DISPATCHER

The constants are defined as static fields of Tibems. The values of those constants are the actual property names.

In .NET, methods exist to get and set the properties. This method provides an alternate way to get property values, which is consistent with the EMS Java API (for easy porting to .NET).

NOTE: In case of system properties if the values are never set then the default values are returned.

Parameters

key	Return the value associated with this property name.

Returns

The value for the given property. If the property is not set, null is returned

static String TIBCO.EMS.Tibems.GetReconnectAttempts ( )

inlinestatic

Returns the reconnect attempts setting.

This setting governs all client Connection objects as they attempt to reconnect to the server after a network disconnect. Its value is a string of the form attempts or attempts,delay:

• attempts limits the number of times that the connection object attempts to reestablish a connection to the server. When this property is absent, the default value is 4. The minimum value is 1.
• delay is the time (in milliseconds) between reconnection attempts. When absent, the default value is 500. The minimum value is 250.

This method returns the string argument to Tibems.SetReconnectAttempts, rather than the numeric value of the setting. If the client has not set a value, this method returns the null string.

static int TIBCO.EMS.Tibems.GetReconnectAttemptTimeout ( )

inlinestatic

Returns the connect attempt timeout value

static bool TIBCO.EMS.Tibems.GetSessionDispatcherDaemon ( )

inlinestatic

Return the dispatcher thread setting.

When a program uses asynchronous message consumers (either message listeners or .NET message event handler delegates), EMS creates internal dispatcher threads for each Session that has at least one asynchronous message consumer. When this setting is true, those dispatcher threads are daemon threads; when false (the default) they are not daemon threads.

static int TIBCO.EMS.Tibems.GetSocketReceiveBufferSize ( )

inlinestatic

Returns the size of socket receive buffer.

When set, this value overrides the operating system's default for the size of receive buffers associated with sockets that the client uses for connections to the server. (Some operating systems do not allow you to override the default size.)

Returns

The size of the socket's receive buffer.

static int TIBCO.EMS.Tibems.GetSocketSendBufferSize ( )

inlinestatic

Return the size of socket send buffer

When set, this value overrides the operating system's default for the size of send buffers associated with sockets that the client uses for connections to the server. (Some operating systems do not allow you to override the default size.)

Returns

The size of the socket's send buffer.

static bool TIBCO.EMS.Tibems.IsConsumerMulticast ( MessageConsumer  consumer )

inlinestatic

Checks if a MessageConsumer is receiving messages over multicast.

Parameters

consumer

the MessageConsumer to check

Deprecated:

As of release 8.3

static void TIBCO.EMS.Tibems.MakeWriteable ( Message  message )

inlinestatic

Set message to writeable state without resetting its content.

Parameters

message

The message to become writeable.

static void TIBCO.EMS.Tibems.RecoverMsg ( Message  msg )

inlinestatic

Recover a single message.

Parameters

msg	the Message to recover

static void TIBCO.EMS.Tibems.SetAllowCallbackInClose ( bool  allow )

inlinestatic

Deprecated, use Tibems.SetAllowCloseInCallback instead.

Deprecated:

Use Tibems.SetAllowCloseInCallback instead.

static void TIBCO.EMS.Tibems.SetAllowCloseInCallback ( bool  allow )

inlinestatic

Sets if the Session.Close, Connection.Close or Connection.Stop methods can be called in the IMessageListener.OnMessage callback.

According to the JMS 2.0 specification, calling any of these methods must trigger an IllegalStateException. If this property is set then the Close or the Stop method can be called inside the callback and it will not throw an exception and will proceed without waiting for the same callback to return. Note: This method replaces the deprecated method SetAllowCallbackInClose.

Parameters

allow

When true, EMS overrides the JMS specification so client callbacks may call Close or Stop methods.When false (the default), EMS obeys the JMS specification.

static void TIBCO.EMS.Tibems.SetConnectAttempts ( string  specs )

inlinestatic

Modify the connection attempts setting determining the number of attempts the client makes to connect to the server.

When too many clients connect to the same server, the server may not be able to accept all connections at the same time. This parameter specifies the number of attempts and delay between the attempt the connections perform in order to connect to the server. The value of this parameter is a String in the form "NN[,DELAY]" where NN is the number of attempts and DELAY is delay in milliseconds between the attempts. Minimum value of NN is 1, minimum value of DELAY is 250 milliseconds.

Parameters

specs

Set the connect setting to these specifications. The value must be string of the form attempts or attempts,delay: attempts limits the number of times that the connection object attempts to establish a connection to the server. When this property is absent, the default value is 2. The minimum value is 1. delay is the time (in milliseconds) between connection attempts. When absent, the default value is 500. The minimum value is 250.

static void TIBCO.EMS.Tibems.SetConnectAttemptTimeout ( int  timeout )

inlinestatic

Set the maximum amount of time a client will wait for the connection to be established

When too many clients connect to the same server, the server may not be able to accept all connections at the same time or may run out of system resources. This method specifies the maxmimum amount of time a client is willing to wait for a connection to be established. Internally the client library will tear down any hung connections (either because of non-availability of system resources or some other EMS server problem) after the timeout period has elapsed.

Parameters

timeout

Timeout value, in milliseconds. The minimum value is 100 milliseconds, if value less than 100 milliseconds is specified, then the minimum value of 100 milliseconds is used. Default value is 0 (no timeout).

static void TIBCO.EMS.Tibems.SetEncoding ( String  encodingName )

inlinestatic

Set global string encoding for messages

Clients can override the global encoding for individual messages. When neither a global nor an individual message encoding has been set, then EMS encodes the strings of an outbound message using the default UTF-8 encoding.

This encoding applies to all strings in message body fields (names and values), and properties (names and values). It does not apply to message header fields. The methods BytesMessage.ReadUTF and BytesMessage.WriteUTF are exempt from global and individual encoding settings.

Note: The only encoding names that are supported by the .NET client are the ones defined by the .NET framework. Please refer to the .NET framework documentation for a complete list of the encoding names supported by the .NET framework.

Parameters

encodingName

The name of the encoding (for example, "utf-8"). For a list of standard encoding names, see www.iana.org.

Exceptions

EMSException

If the encoding is not supported.

static void TIBCO.EMS.Tibems.SetExceptionOnFTEvents ( bool  callExceptionListener )

inlinestatic

Sets if ExceptionListener set on the Connection should be called for all the following events: disconnected, each reconnect attempt, and reconnected.

Similarly to Tibems.SetExceptionOnFTSwitch, if this method is called and if a Connection's ExceptionListener is set, (and the connection has FT urls), then all above events will trigger the call to the ExceptionListener.OnException callback with an EMSException which has the vendor error code (EMSException.ErrorCode) set to the String in the form:

FT-SWITCH: event

where event is:

• Disconnected from server url, will attempt to reconnect
• Reconnecting to next server url, attempt n out of m
• Reconnected to server url

An application can recognize such calls by analyzing the error code in the passed EMSException and perform necessary actions. Notice that this method replaces the method Tibems.SetExceptionOnFTSwitch(), which means that if both are called, only one "reconnected" event will be passed to the ExceptionListener.OnException callback (the one described above). We recommend that if Tibems.SetExceptionOnFTSwitch() was formerly used, and the user wishes to capture all FT events, this new property be used instead and the ExceptionListener.OnException callback modified to handle these new vendor error codes.

Note: When the exception listener is called, the exception listener is not allowed to call any EMS method. To do so in this case risks a deadlock in the client.

Parameters

callExceptionListener

When true, the connection's ExceptionListener catches an EMSException, which contains the server url from which the client got disconnected from, the server url the client is attempting to reconnect to, and the server url to which the client has reconnected to. Each of these events triggers the call to the exception listener.When false, fault-tolerant events such as initial disconnection and further reconnect attempts do not trigger call to the exception listener.

static void TIBCO.EMS.Tibems.SetExceptionOnFTSwitch ( bool  callExceptionListener )

inlinestatic

Sets if ExceptionListener set on the Connection should be called after fault-tolerant switch.

This setting determines exception behavior when the client successfully switches to a different server (fault-tolerant failover).

When an application performs fault-tolerant switch it may notify the Connection's ExceptionListener by calling it with EMSException providing the information about fault-tolerant switch. If calling the Connection's ExceptionListener is set, it is called with the EMSException which has the vendor error code (EMSException.getErrorCode) set to the String in the form:

FT-SWITCH: <I>new-server-url</I>

An application can recognize such calls by analyzing the error code in the passed EMSException and perform necessary actions. Notice that the ExceptionListener is called with the special EMSException only when fault-tolerant switch has been performed succesfully. In case the fault-tolerant switch has failed, the Connection's ExceptionListener will be called with regular EMSException (it will not have error code in the form 'FT-SWITCH: new-server-url') specifying that the connection to Server has been terminated. Notice that by default Connection's ExceptionListener is not called after a successfull fault-tolerant switch.

Note: When the exception listener is called, the exception listener is not allowed to call any EMS method. To do so in this case risks a deadlock in the client.

Parameters

callExceptionListener

When true, the connection's ExceptionListener catches an EMSException, which contains the name of the new server.When false, fault-tolerant failover does not trigger an exception in the client.

static void TIBCO.EMS.Tibems.SetMessageEncoding ( Message  message, string  encodingName  )

inlinestatic

Set the character encoding for an individual message

This encoding for an individual message overrides the global encoding. When neither a global nor an individual message encoding has been set, then EMS encodes the strings of an outbound message using the default UTF-8 encoding.

This encoding applies to all strings in message bodies (names and values), and properties (names and values). It does not apply to header names or values. The methods BytesMessage.ReadUTF and BytesMessage.WriteUTF are exempt from global and individual encoding settings.

Parameters

message	Set the encoding for this message.
encodingName	The name of the encoding (for example, "utf-8"). For a list of standard encoding names, see www.iana.org.

Exceptions

EMSException

If the encoding is not supported

static void TIBCO.EMS.Tibems.SetMulticastDaemon ( string  port )

inlinestatic

Set the port on which the EMS client will connect to the multicast daemon.

A connection to the multicast daemon is required when multicast is enabled and a MessageConsumer is subscribed to a multicast-enabled topic. Setting the port with this method will override the default port supplied by the server and the port specified on the connection factory.

Parameters

port	the port of the multicast daemon

Deprecated:

As of release 8.3

static void TIBCO.EMS.Tibems.SetMulticastEnabled ( bool  enabled )

inlinestatic

Set whether MessageConsumers subscribed to a multicast-enabled topic will receive messages over multicast.

When enabled, MessageConsumers subscribed to a multicast-enabled topic will receive messages over multicast. The default is enabled.

Parameters

enabled

true to enable multicast, false to disable multicast. Default value is enabled.

Deprecated:

As of release 8.3

static void TIBCO.EMS.Tibems.SetNPSendCheckMode ( MessageProducer  producer, int  mode  )

inlinestatic

Set the mode defining when a producer should check the result of sending a NON_PERSISTENT message.

This mode only applies to messages sent using the MesssageDeliveryMode.NonPersistent delivery mode and a non-transactional Session; it does not apply to cases when a message was sent using MessageDeliveryMode.Persistent or the {MessageDeliveryMode.ReliableDelivery} delivery mode or if the corresponding Session is transactional. If the producer's send check mode is not set, it may execute the mode applied globally to all producers via the EMS server parameter. Setting any mode other than {NPSEND_CHECK_DEFAULT} unconditionally overrides the global setting defined by the server.

Normally, applications use the server's setting or configure producers with a specific send mode only once. However, if required, applications may choose to change this mode before sending every message.

When a producer does not check the result of sending a message, it will not know if any problem has occurred and the message was not processed by the server. If a producer checks the result of the send, the Send method will receive the server's response to the send and throw the appropriate exception if any problem has occurred. However, this will reduce the producer's performance.

Parameters

producer	message producer, must not be null
mode	one of constants {NPSEND_CHECK_DEFAULT}, {NPSEND_CHECK_ALWAYS}, {NPSEND_CHECK_NEVER}, {NPSEND_CHECK_TEMP_DEST}, {NPSEND_CHECK_AUTH} or {NPSEND_CHECK_TEMP_AUTH}

Exceptions

ArgumentException

if the producer is null or if the mode value is invalid.

GetNPSendCheckMode

static void TIBCO.EMS.Tibems.SetPingInterval ( int  seconds )

inlinestatic

Set the interval at which the client tests network connectivity

Clients test network connectivity by sending ping requests to the server at regular intervals. This method sets that interval (in seconds). If your program calls this method, it must do so before creating its first Connection object; after creating that object, this call has no effect.

Parameters

seconds

Ping at this interval (in seconds).

Zero is a special value that disables ping testing.

static void TIBCO.EMS.Tibems.SetProperty ( string  key, object  val  )

inlinestatic

Modify a property value

In .NET, methods exist to get and set the properties. SetProperty provides an alternate way to set property values, which is consistent with the EMS Java API (for easy porting to .NET).

You can supply any of the following constants:

• PROP_SOCKET_RECEIVE
• PROP_SOCKET_SEND
• PROP_CONNECT_ATTEMPTS
• PROP_RECONNECT_ATTEMPTS
• PROP_CLOSE_IN_CALLBACK
• PROP_PING_INTERVAL
• PROP_FT_SWITCH_EXCEPTION
• PROP_MESSAGE_ENCODING
• PROP_DAEMON_DISPATCHER

The constants are defined as static fields of Tibems. The values of those constants are the actual property names.

Parameters

key	Set the value associated with this property name.
val	Set the property to this value.

static void TIBCO.EMS.Tibems.SetReconnectAttempts ( string  specs )

inlinestatic

Sets the parameter for the number of attempts the connections make to reconnect to the backup server during fault-tolerant switch.

This parameter is similar to the parameter set by setConnectAttempts method. The difference is that it may be necessary to use different parameters during reconnect than during the initial connect. Initial connect of the clients to the server is normally distributed in time and there are less chances of the server exceeding its maximum accept queue. During fault-tolerant switch, all connected clients automatically try to reconnect to the backup server, approximately at the same time. When the number of connections is large, it may require more attempts to reconnect than the initial connect.

Parameters

specs

Set the reconnect setting to these specifications. The value must be string of the form attempts or attempts,delay: attempts limits the number of times that the connection object attempts to reestablish a connection to the server. When this property is absent, the default value is 4. The minimum value is 1. delay is the time (in milliseconds) between reconnection attempts. When absent, the default value is 500. The minimum value is 250.

static void TIBCO.EMS.Tibems.SetReconnectAttemptTimeout ( int  timeout )

inlinestatic

Sets the maximum amount of time a client will wait for the reconnect to complete

This method is similar to SetConnectAttemptTimeout. However, during the initial connect of the clients to the server, the time for each connect attempt is normally distributed and there are less chances of the server exceeding its maximum accept queue. During a fault-tolerant switch, all of the clients automatically try to reconnect to the backup server at approximately the same time. When the number of connections is large, it may require more reconnect time to reconnect than the initial connect.

Parameters

timeout

Timeout value, in milliseconds. The minimum value is 100 milliseconds, if value less than 100 milliseconds is specified, then the minimum value of 100 milliseconds is used. Default value is 0 (no timeout).

static void TIBCO.EMS.Tibems.SetSessionDispatcherDaemon ( bool  makeDaemon )

inlinestatic

Set the dispatcher thread setting

This method sets if Session dispatcher threads should be daemon. Some operating systems may ignore this setting.

When a program uses asynchronous message consumers (either message listeners or .NET message event handler delegates), EMS creates internal dispatcher threads for each Session that has at least one asynchronous message consumer. By default session dispatcher threads are not set to be daemon threads.

Parameters

makeDaemon

When true, dispatcher threads are daemon threads. When false, (the default) they are not daemon threads.

static void TIBCO.EMS.Tibems.SetSocketReceiveBufferSize ( int  size )

inlinestatic

Set the size of socket receive buffers

This value overrides the operating system's default for the size of receive buffers associated with sockets that the client uses for connections to the server.

Use this call before creating server connections. This call sets an override buffer size for new socket buffers; it does not change the size of existing socket buffers.

Parameters

size	Sockets use receive buffers of this size (in kilobytes).

static void TIBCO.EMS.Tibems.SetSocketSendBufferSize ( int  size )

inlinestatic

Set the size of socket send buffers

This value overrides the operating system's default for the size of send buffers associated with sockets that the client uses for connections to the server.

Use this call before creating server connections. This call sets an override buffer size for new socket buffers; it does not change the size of existing socket buffers.

Sets the size of the socket send buffer size for client connections. Some operating systems may ignore this setting.

Parameters

size	Sockets use send buffers of this size (in kilobytes).

static void TIBCO.EMS.Tibems.SetTraceFile ( string  fileName )

inlinestatic

Use this method to instruct the TIBCO EMS Client library to direct the tracing, that would normally go to stderr or stdout, to a file named fileName.

This call alone does not generate tracing, that is, the tracing still needs to be enabled as usual: from the admin tool and/or with the ssl trace parameter in order to trace SSL connections' handshake.

The trace file is opened in append mode. An IOException will be thrown if the file can not be opened, and the tracing will be directed to stderr or stdout based on the connection's tracing setting (check the admin command set server client_trace for more details).

Since there is only one trace file allowed, an InvalidOperationException will be thrown if this method is called with a non null file name after a trace file has already been set.

Pass null to this method to instruct the TIBCO EMS Client library to stop directing tracing to the file. Normal tracing (stderr or stdout) will then resume.

Parameters

fileName

the name of the TIBCO EMS Client trace file for this application, or null to stop directing tracing to the file.

Exceptions

InvalidOperationException	if this method is called twice with a non null fileName.
System.IO.IOException	if an error occurs while opening/creating the file.

According to the JMS 2.0 specification, calling any of these methods must trigger an IllegalStateException. If this property is set then the Close or the Stop method can be called inside the callback and it will not throw an exception and will proceed without waiting for the same callback to return. This property is defined as string "tibco.tibjms.close.in.callback".

const string TIBCO.EMS.Tibems.PROP_CONNECT_ATTEMPT_TIMEOUT = "tibco.tibjms.connect.attempt.timeout"

Defines the name of the System Property controlling the maximum time for the connections to connect to the server. When too many clients connect to the same server, the server may not be able to accept all connections at the same time or may run out of system resources. This parameter specifies the amount of time a client is willing to wait for a connection to be established. Internally the client library will tear down any hung connections (either because of non-availability of system resources or some other EMS server problem) after this timeout.

const string TIBCO.EMS.Tibems.PROP_DAEMON_DISPATCHER = "tibco.tibjms.daemon.dispatcher"

Defines the name of the provider property controlling the type of Session dispatcher threads

When application uses message listeners, TIBCO Enterprise Message Serivce creates internal dispatcher threads for each Session which has at least one asynchronous message consumer. By default those dispatcher threads are not set to be daemon threads. If this provider property is defined then the Session dispatcher threads will be created as daemon threads.

This property is defined as string "tibco.tibjms.daemon.dispatcher".

const string TIBCO.EMS.Tibems.PROP_FT_EVENTS_EXCEPTION = "tibco.tibjms.ft.events.exception"

Defines the name of the provider property controlling if ExceptionListener set on the Connection should be called for all the following events: disconnected, each reconnect attempt, and reconnected.

Similarly to Tibems.PROP_FT_SWITCH_EXCEPTION, if this property is set and if a Connection's ExceptionListener is set, (and the connection has FT urls), then all above events will trigger the call to the ExceptionListener.OnException callback with an EMSException which has the vendor error code (EMSException.ErrorCode) set to the String in the form:

FT-SWITCH: event

where event is:

• Disconnected from server url, will attempt to reconnect
• Reconnecting to next server url, attempt n out of m
• Reconnected to server url

An application can recognize such calls by analyzing the error code in the passed EMSException and perform necessary actions. Notice that this property replaces the property Tibems.PROP_FT_SWITCH_EXCEPTION, which means that if both are set, only one "reconnected" event will be passed to the ExceptionListener.OnException callback (the one described above). We recommend that if Tibems.PROP_FT_SWITCH_EXCEPTION was formerly used, and the user wishes to capture all FT events, this new property be used instead and the ExceptionListener.OnException callback modified to handle these new vendor error codes.

This property is defined as string "tibco.tibjms.ft.events.exception".

Note: When the exception listener is called, the exception listener is not allowed to call any EMS method. To do so in this case risks a deadlock in the client.

const string TIBCO.EMS.Tibems.PROP_FT_SWITCH_EXCEPTION = "tibco.tibjms.ft.switch.exception"

Defines the name of the provider property controlling if ExceptionListener set on the Connection should be called during fault-tolerant switch.

When an application performs fault-tolerant switch it may notify the Connection's ExceptionListener by calling it with EMSException providing the information about fault-tolerant switch. If this property is set, the Connection's ExceptionListener is called with the EMSException which has the vendor error code (EMSException.getErrorCode()) set to the string in the form: FT-SWITCH: <new-server-url> An application can recognize such calls by analyzing the error code in the passed EMSException and perform necessary actions. Notice that the ExceptionListener is called with the special EMSException only when fault-tolerant switch has been performed succesfully. In case the fault-tolerant switch has failed, the Connection's ExceptionListener will be called with regular EMSException (it will not have error code in the form 'FT-SWITCH: <new-server-url>' specifying that the connection to Server has been terminated. Notice that if this property is not set then by default Connection's ExceptionListener is not called after a successfull fault-tolerant switch.

This property is defined as string "tibco.tibjms.ft.switch.exception". NOTE: when the exception listener is called, the exception listener is not allowed to call any EMS method. To do so in this case risks a deadlock in the client.

const string TIBCO.EMS.Tibems.PROP_MESSAGE_ENCODING = "tibco.tibjms.message.encoding"

Defines the name of the System Property setting the global encoding name for String values in the message properties and data fields.

This property is defined as String "tibco.tibjms.message.encoding".

const string TIBCO.EMS.Tibems.PROP_MULTICAST_DAEMON = "tibco.tibjms.multicast.daemon"

Defines the name of the System Property specifying the port on which EMS clients will connect to the multicast daemon. This property is defined as String "tibco.tibjms.multicast.daemon".

const string TIBCO.EMS.Tibems.PROP_MULTICAST_ENABLED = "tibco.tibjms.multicast.enabled"

Defines the name of the System Property specifying whether multicast is enabled or disabled for this EMS client. This property is defined as String "tibco.tibjms.multicast.enabled".

As of release 8.3

const string TIBCO.EMS.Tibems.PROP_PING_INTERVAL = "tibco.tibjms.ping.interval"

Defines the name of the System Property setting the ping interval for inactive connections.

When a connection does not send nor receives any data, it may not be able to detect network failure in certain situations. To avoid this, inactive connections periodically send "ping" messages to the server. Default interval is 60 seconds. In some cases it may take several intervals to detect network failure. The value of this property is a string encoding the ping interval in seconds, e.g. "60". Zero value disables ping messages.

This property is defined as String "tibco.tibjms.ping.interval".

const string TIBCO.EMS.Tibems.PROP_RECONNECT_ATTEMPT_TIMEOUT = "tibco.tibjms.reconnect.attempt.timeout"

Defines the name of the System Property controlling the maximum time for connections to reconnect to the backup server during the fault-tolerant switch. This property is similar to PROP_CONNECT_ATTEMPTS_TIMEOUT. The difference is that it may be necessary to use different parameters during reconnect than during the initial connect. Initial connect of the clients to the server is normally distributed in time and there are less chances of the server exceeding its maximum accept queue. During fault-tolerant switch, all connected clients automatically try to reconnect to the backup server, approximately at the same time. When the number of connections is large, it may require more reconnect time to reconnect than the initial connect. The value of this property is an integer in milliseconds. This property is defined as String "tibco.tibjms.reconnect.attempt.timeout".

const string TIBCO.EMS.Tibems.PROP_RECONNECT_ATTEMPTS = "tibco.tibjms.reconnect.attempts"

Defines the name of the provider property controlling the number of attempt the connections make to reconnect to the backup server during the fault-tolerant switch.

This property is similar to PROP_CONNECT_ATTEMPTS. The difference is that it may be necessary to use different parameters during reconnect than during the initial connect. Initial connect of the clients to the server is normally distributed in time and there are less chances of the server exceeding its maximum accept queue. During fault-tolerant switch, all connected clients automatically try to reconnect to the backup server, approximately at the same time. When the number of connections is large, it may require more attempts to reconnect than the initial connect. The value of this property is a string in the form "NN[,DELAY]" where NN is the number of attempts and DELAY is delay in milliseconds between the attempts. Minimum value of NN is 1, minimum value of DELAY is 250 milliseconds. Default value used is "4,500".

This property is defined as string "tibco.tibjms.reconnect.attempts".

const string TIBCO.EMS.Tibems.PROP_SOCKET_RECEIVE = "tibco.tibjms.socket.receive"

Defines the name of the provider property setting the size of the socket receive buffer size in kilobytes for client connections.

The value of this property is a string encoding the number of kilobytes, e.g. "256". Some operating systems may ignore this setting.

This property is defined as String "tibco.tibjms.socket.receive".

const string TIBCO.EMS.Tibems.PROP_SOCKET_SEND = "tibco.tibjms.socket.send"

Defines the name of the provider property setting the size of the socket send buffer size in kilobytes for client connections.

The value of this property is a string encoding the number of kilobytes, e.g. "256". Some operating systems may ignore this setting.

This property is defined as String "tibco.tibjms.socket.send".

The multicast exception event handler

The client library raises an event if it detects a problem with EMS multicast. The program implements a handler delegate to processes it asynchronously and registers the delegate here.

Delegate declaration for multicast exception handler is as follows:

public delegate void EMSMulticastExceptionHandler(object sender, EMSExceptionEventArgs args); <br/>
sender: The source of the event, the connection in this case. <br/>
args: The event argument, <see cref="EMSExceptionEventArgs"/> <br/> 

Example of using the exception event handler:

...
Tibems.MulticastExceptionHandler += new EMSMulticastExceptionHandler(handleEx);
...
private void handleEx(object sender, EMSExceptionEventArgs arg)
{
   Connection   connection = arg.Connection;
   Session      session    = arg.Session;
   Consumer     consumer   = arg.Consumer;
   EMSException e          = arg.Exception;
   Console.WriteLine("Exception: " + e.Message);
}
...
