Messages may be provided to a source queue in serialized order, each message associated with a serialization context. The messages may be buffered in the source queue until a transmission time is reached, in turn, for each buffered message. Transmission-ready messages may be sent from the source queue according to the serialized order, using the serialization context, while continuing to store existing messages that are not yet transmission-ready. A queue assignment of the serialization context may be changed to a target queue. Subsequent messages may be provided with the serialization context to the target queue for buffering therein, while remaining transmission-ready messages may be continued to be sent from the source queue. The existing messages from the source queue associated with the serialization context may be determined to have been sent, and the subsequent messages may be sent from the target queue in serialized order, using the serialization context.

Maintenance of message serialization in multi-queue messaging environments

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for facilitating communication between enterprise software applications. Some enterprise software systems communicate using a message protocol designed for use with an exchange system. Those systems require the exchange system to communicate using that message protocol. To communicate with systems using that message protocol, a local system can build a message formatted in accordance with the message protocol, even without an exchange system. The local system stores configuration data and uses the configuration data to build the message.

Facilitating communication between enterprise software applications

A system and method for filtering messages in a messaging system is described. The system includes a user interface configured to receive user input for defining one or more message filters. Each message filter specifies predefined criteria by which a message is to be stopped. The system further includes a filter module comprising the one or more filters, and a queue connected with the filter module for queuing messages stopped according to one of the one or more filters. In a method, messages in the messaging system are stopped according to predefined criteria. Stopped messages are restarted according to a job executed by the messaging system.

Time and event controlled message processing

Various embodiments of systems and methods for processing data in shared memory are described herein. A number of work processes of an application server write data in corresponding areas of shared memory. At least one data unit for a first process is read from a first area of the shared memory by the first process. The first process also reads at least one unit of data for a second process from a second area of the shared memory. The first process writes information in a third area of the memory to indicate that the at least one unit of data for the first process and the at least one unit of data for the second process are read. The read data units are aggregated and saved in a storage by the first process.
