The details of this message are listed in the extraInfo field. The details of this error are listed in the extraInfo field. These status tuples will only be generated if the operator's Emit 'Message Sent' Status Tuples property is enabled. The schema for this port describes the received JMS message, and is discussed in detail in the Message Translation section above.
If the operator's Enable Status Port setting is set, an output port is added to allow the operator to send status tuples when interesting events occur such as when a destination subscription succeeds or fails, for example. If the operator's Enable Status Port setting is set, an output port is added to allow the operator to send status tuples when interesting events occur such as when a connection attempt succeeds or fails, for example.
If the operator's Enable Status Port setting is set, an output port is added to allow the operator to send status tuples when interesting events occur such as when a message was successfully acknowledged, for example. Transaction Commit Successful : The operator successfully committed the transaction.
Transaction Commit Failed: An error occurred while committing the transaction. Transaction Rollback Successful : The operator successfully rolled back the transaction. Transaction Rollback Failed: An error occurred while rolling back the transaction. On suspend, if either the JMS Consumer or Producer is currently processing a message, it finishes processing that message or tuple to completion before suspending.
That is, the StreamBase application itself finishes processing the message or tuple before the JMS operator returns from a suspend command. Once this has occurred, if any messages or tuples for the JMS Producer are delivered while the operator is suspended, it drops the messages or tuples and fails to acknowledge them.
Your StreamBase applications that use these adapters still compile and run under current StreamBase Server releases. However, if you must maintain an application that continues to use the 7. Introduction to JMS. JMS Operators Introduction. Select and double-click the newly placed canvas icon to open its Properties view. Message Translation. If jmsHeader is present but some fields are missing, the corresponding header fields are left unset in the outgoing JMS message.
JMS headers contain a fixed set of values, each of which has a StreamBase field name. In the JMS message, this is set to the actual javax. Destination object instance, but in the Tuple it is simply set to the destination's name, with the to and from conversions happening automatically.
For Map Messages, this means corresponding fields are used on the JMS message to get and set values, for example. Message Converter Classes. MapMessage Converters. TextMessage Converters. BytesMessage Converters. Custom Converters. JAR File Requirements. Important Regardless of the JMS vendor used, you must also provide a copy of jms.
Properties View Settings. General Tab. Operator Properties Tab. None Destination Definition required string StreamSQL name: destinationType Consumer Producer Whether the destination to which to connect is predefined in the configuration Preconfigured or will dynamically specified at runtime Dynamic. If the latter is chosen, an input port is automatically added to the operator to receive subscription requests to connect to destinations on the fly. Otherwise the adapter waits for an explicit connect command before attempting connection.
See Input Port Schemas. True Enable Status Port optional StreamSQL name: enableStatusPort Consumer Producer If selected, this option causes the adapter to expose a new output port used to send status tuples when interesting events occur such as error messages from the server, or notification of JMS messages sent. This in effect creates back-pressure on the JMS server, which may be useful in some use cases. Once some of the messages currently in flight in the application are acknowledged using the JMSAck operator , message consumption resumes.
Leaving this setting empty or setting it to -1 means the operator will keep reading messages from the server regardless of the number unacknowledged messages. If this option is selected, a corresponding field is added to the JMS message with a value of null.
This setting can be higher than the containing application's log level. If set lower, the system log level is used. Edit Schemas Tab. Concurrency Tab. Caution Concurrency settings are not suitable for every application, and using these settings requires a thorough analysis of your application.

Configuration Example: Solace. Operator Port Schemas. EMS is based on creation and delivery of messages. Messages are structured data that one application sends to another. JMS supports both messaging models: point-to-point queuing and publish-subscribe. JMS was defined to allow Java application to use enterprise messaging systems. More importantly, it provides a common way for Java applications to access such enterprise messaging systems.
JMS messages have a basic format that is simple but highly flexible, allowing you to create messages that match formats used by non-JMS applications on heterogeneous platforms.
A JMS message has three parts: a header, properties, and a body. Only the header is required. Durable subscribers to a EMS topic are those subscribers which are entitled to receive a message published to a topic once they are alive and ready to consume; even if they were not active when the message was published by the publisher to that topic.

Enterprise Software. What are the cases when we can use one and not the other? Thanks in advance. In my opinion as long as the message rate is not too high, you can go ahead and use JMS. Javin Paul Posted January 12, 0 Comments.
Thanks Javin.
