Abstract:
There is disclosed a source messaging system having a queue for receiving messages. The source messaging system has means for determining whether a message should be permitted to become INDOUBT. This is done by retrieving a value denoting the maximum number of messages that may be permitted to become INDOUBT at any one time; determining whether the message falls within the range denoted by the value; and responsive to determining that the message falls within the range, permitting the message to become INDOUBT.
Abstract:
Requests from a client to put messages into an input queue are intercepted before reaching the input queue. The intercepted requests which refer to a message destined for the server application are established. Information associated with the server application indicates that the server application will process such a message according to a predetermined manner. A request associated with the server application for retrieving such a message is transactional, and the server application uses a one-phase commit for retrieving such a message. Such a message can then be matched with the server application's request such that the server application can retrieve the message. In this way, such messages by-pass the input queue, and are, therefore, not logged, resulting in a reduction of I/O.
Abstract:
This invention relates to a class of heterocycles and their metal complexes, and is particularly concerned with the use of these compounds in the preparation of prodrugs or as prodrugs that may be activated under hypoxic conditions by enzymes or by therapeutic ionising radiation, in the treatment of cancer. The invention also relates to the use of these heterocycles and the corresponding metal complexes in the preparation of medicaments and to compositions including the heterocycles or their metal complexes and to methods for preparing these compounds.

Abstract:
The multiple driver occupied passenger vehicles transporter system (Autobus) provides a way to efficiently, economically and safely increase the highway vehicle flow rate of cars per lane per hour. Autobus employs a vehicle transporter, terminal, sensors and systems that provide a way to quickly load and unload driver occupied passenger vehicles on and off of the vehicle transporter. Autobus provides a way to safely transport multiple driver occupied passenger vehicles, including cars, sport utility vehicles (SUVs) and light trucks.
Abstract:
A method of performing message operations includes receiving a message operation request identifying a queue, retrieving a list of the subset of partitions associated with the alias received in the request, and selecting at least one of the partitions within the retrieved subset. According to the method, the queue includes a plurality of partitions, the request identifies the queue with an alias, and the alias having a subset of the plurality of partitions associated therewith.
Abstract:
A method and system of controlling access to a destination (17, 23, 24) in a data processing network where the destination is limited to a fixed number of requesters responds to a new request (50) for access from a given requestor (20) by determining whether the fixed number would be exceeded. If the fixed number would not be exceeded (51), the new request is granted by connecting (52) the given requester to the destination. If the fixed number would be exceeded, the liveness of the or each current connection to a respective requester is tested (55). If the liveness test succeeds, the new request is rejected but if the liveness test fails, the new request is granted (52).

Abstract:
Disclosed is a method for administering messages. In response to a determination that one or more consuming applications have failed to process the same message on a queue a predetermined number of times, the message is made unavailable to consuming applications. Responsive to determining that a predetermined number of messages have been made unavailable to consuming applications, one or more consuming applications are prevented from consuming messages from the queue.
