TIBCO EMS STEP -8 : JMS Message Types

-

  JMS Message Types :
§  Message: This message type has no body. This is useful for simple event notification.
§  TextMessage:  nothning but a sequence of characters.
§  MapMessage: A set of name/value pairs.
§  BytesMessage: A stream of uninterrupted bytes. The bytes are not typed;that is, they are not assigned to a primitive data type.
§  StreamMessage: A stream of primitive values and  Each set of values belongs to a primitive data type, and must be read sequentially.
§  ObjectMessage: A serializable object constructed in the Java programming language.
Ø  EMS supports messages up to a maximum size of 512MB.
Ø  When the EMS server has several messages ready to deliver to a consumer client, and must select among them, then it delivers messages with higher priority before those with lower priority.
Ø  JMS supports PERSISTENT and NON_PERSISTENT delivery modes for both topic and queue. EMS extends these delivery modes to include a RELIABLE_DELIVERY .

TIBCO EMS FAQ -5

131) What happens if the message expires/exceeded the value specified by maxredelivery property on queue? If the jms_preserve_undelivered property is set to true, then it moves he message to undelivered message queue, if set to false, the message is deleted by the server. 132) What are the wild cards that we use in ems?how do they work for queues and topics? *,> We can subscribe to wildcard topics, but cant publish to them. Where as in case of queues we can’t either send /receive. 133) Are bridges transitive? No 134) Tell me about flow control on destinations? Sometimes the producer may send messages faster than the consumers can receive them. So, the message capacity on the server will be exhausted. So we use flow control. Flow control can be specified on destinations. 135) Tell me about flow control on bridges and routes? Flow control has to be specified on both sides of bridges where as on routes it operates differently on sender side and receiver side. 136) Nam...

31) What happens if you use check point activity first and confirm next? Ans)In the case of confirmable messages , you must consider the consequences of performing a checkpoint before or after a Confirm activity. If the checkpoint is taken before the Confirm activity, then a crash occurs after a checkpoint but before a confirm, the original message is resent. In this case, the restarted process can no longer send the confirmation. However, a new process is started to handle the resent message, and you can implement your process to handle the restarted and new processes appropriately. If the checkpoint is taken after a Confirm activity, there is potential for a crash to occur after the Confirm but before the checkpoint. In this case, the message is confirmed and therefore not redelivered. The process instance is not restarted, because the crash occurred before the checkpoint. You must consider the type of processing your process definition performs to determine when a checkpoint i...
