摘要:
A method for a messaging engine to control messaging within a virtual machine having a heap is disclosed. The messaging engine creates a list of destinations associated with a messaging engine and receives parameters associated with the heap. The messaging engine determines total heap usage and based on the parameters associated with the heap and the total heap usage, controls message production rates of producers associated with the destinations.

A first queue stores messages to be consumed. A second queue temporarily stores completely duplicative messages that have message identifiers equal to message identifiers of messages currently being processed s and that have times equal to times of the messages being processed; processing of the completely duplicative messages never occurs. By comparison, a partially duplicative message has its processing delayed until the message of which it is partially duplicative has been finished being processed. A partially duplicative message has a message identifier equal to a message identifier of a message referenced within the non-persistent store and has a time unequal to a time of the message referenced within the non-persistent store is moved from the first to the second queue. A non-persistent store stores references to the messages currently being processed. Once the messages are finished being processed, the references to them are removed from the non-persistent store.
摘要:
A method of controlling the retention of publications in a publish/subscribe system, the method comprising receiving, at a message broker, a first publication from a publisher on a topic; receiving, at the message broker, a second publication from the publisher on the topic; identifying, at the message broker, whether the first publication should be overwritten with the second publication and, if not, retaining at least payload data from both the first and second publications on the topic; and storing, for the second publication, if retained, data indicating when the second publication was published to the broker. Other methods, apparatus, and computer readable media are also provided.
摘要:
Allocating space for storing heterogeneous messages in a message queue according to message classification. The classification may comprise message type, application type, network type, and so forth. Messages of multiple classification values may be queued in a single queue, referred to as a primary queue. When the allocated portion of the primary queue is reached for a particular message classification, then subsequent messages having that classification are sent to a secondary queue for queuing. The secondary queue also allocates space according to message classification. When space for a particular message classification becomes available in the primary queue, one or more messages having that classification may be moved from the secondary queue to the primary queue.
摘要:
A method, system, and computer usable program product for mitigating distribution or consumption of counterfeit products in a supply chain are provided in the illustrative embodiments. A first set of identifiers is generated to associate with a product to be manufactured. The first set of identifiers includes identifiers corresponding to a customer reference number (CRN), a customer acknowledgment number (CAN), and a merchant acknowledgment number (MAN). The first set of identifiers is associated with the product and a status indicator. The status indicator is set to a first value representative of the product being an original product and the product being available for sale. The first set of identifiers is transmitted to another second application.
摘要:
Message integrity in a messaging oriented middleware system is preserved by determining a message producer's level of message integrity by examination of connection details between the message producer and a messaging engine. The message producer's level of integrity is stored in a memory of the messaging engine. The message is then stored in the designated destination using the message producer's level of integrity. The message is sent from the designated destination to a consumer when it is determined that the consumer conforms to the integrity levels.

A method, system, and computer usable program product for improved manufacturing and distribution to avoid counterfeit products in a supply chain are provided in the illustrative embodiments. For manufacturing to avoid a counterfeit product, a product to be manufactured is selected. Production volume information is determined, the production volume information including a number of units of the product to be produced. An identifier of a manufacturer of the product, an identifier of the product, and the production volume information are sent and several sets of identifiers are received. Each set of identifiers include identifiers corresponding to a customer reference number (CRN), a customer acknowledgment number (CAN), and a merchant acknowledgment number (MAN). One set of identifiers is uniquely associated with one unit of the product being produced. A unit of the product is manufactured such that the unit includes a corresponding set of identifiers.

摘要:
In the context of middleware products, an arrangement wherein a sender tags messages with authorization information identifying those users or groups who are authorized to view or receive the messages. Thus, even if multiple users will be connected to the same queue for reading messages, only specific receivers/consumers will be able to get the messages. Not only is a comfortable degree of security ensured, but the need to waste system resources, e.g., by using multiple queues for different kinds of messages, is summarily avoided.
摘要:
A method, system, and computer usable program product for pre and post purchase identification of counterfeit products in a supply chain are provided in the illustrative embodiments. A customer reference number (CRN) associated with a unit of product is identified. The unit of product has associated therewith a unique set of identifiers including the CRN, a customer acknowledgment number (CAN), and a merchant acknowledgment number (MAN). The CRN is sent to a second application and a message is received from the second application in response to sending the CRN. If the message includes a second CAN that is not the same as the CAN associated with the unit, the unit is determined to be a counterfeit product.
