Abstract:
An enterprise service bus client accesses a user's biometric information, where the biometric information is accessed from a biometric input device coupled to the enterprise service bus client. Furthermore, the enterprise service bus client retrieves a certificate using the user's biometric information. With the certificate, the enterprise service bus client establishes a connection with an enterprise service bus server and accesses an enterprise service bus service.
Abstract:
A forum service that is hosted by a server in an enterprise service bus receives a message from a client, the message being directed to a service in the enterprise service bus. The forum service acts as a message transport in the enterprise service bus. A thread is generated in a forum managed by the forum service for communications between the client and the service. The message is stored in the thread. The service is notified of the message, wherein the service to receive the message, process the message and post a response message to the thread.
Abstract:
A middleware layer running on a computing device determines capabilities of the computing device in response to receiving a request for an application. The middleware layer identifies a service level agreement associated with the application. The middleware layer selects one or more services of the middleware layer to assign to the application based on the service level agreement and the capabilities of the computing device. The middleware layer determines whether to install the one or more services on the computing device or on a remote computing device based on the service level agreement, the capabilities of the computing device and properties of the one or more services.
Abstract:
A server computing device identifies locations of a plurality of data items in a distributed data store. The server computing device generates at least one bloom filter that contains information to identify probable locations of the plurality of data items. The server computing device transmits the at least one bloom filter to one or more client computing devices, wherein the at least one bloom filter is usable by the one or more client computing devices to determine the probable locations of the data items.
Abstract:
A local machine receives a service request from a parent transaction coordinator hosted by a remote machine, the service request including a transaction context. The transaction context is cached at the local machine. Processing logic on the local machine monitors a service as the service performs work to comply with the service request. Processing logic determines when to generate a subordinate transaction coordinator and when to register the subordinate transaction coordinator with the parent transaction coordinator based on the work performed by the monitored device.
Abstract:
A client sends a request message to a process hosted by a remote server via a middleware service, wherein the request message specifies a procedure for the process to execute. The client waits a predetermined time period to receive a response message from the process. If no response message is received within the predetermined time period, the client probes the process to determine why no response message has been received, wherein said probing reveals thread level information about the process.
Abstract:
A processing device receives a request to initiate a new transaction. The processing device identifies one or more components of that will be used by the new transaction. The components may include hardware components and software components that operate on the hardware components. A timeout period is determined to apply to the new transaction based on properties of the one or more components and a current resource utilization of the one or more components. The new transaction is then initiated, wherein the determined timeout period is assigned to the new transaction.
Abstract:
A recovery manager detects that a distributed transaction is unresolved for a first participant of said distributed transaction. The recovery manager identifies that the distributed transaction is unresolved for a second participant of said distributed transaction. The recovery manager generates a list of participants for which the distributed transaction is unresolved, the list including an entry for the first participant and an additional entry for the second participant. The recovery manager determines a result of the distributed transaction based on information received from a remote coordinator of said distributed transaction. The recovery manager notifies each participant identified in the list of the result.
Abstract:
Components of a distributed computing system are monitored, the components including hardware components and software components that operate on the hardware components. At least one of the software components is a service that includes a service level agreement. Performance characteristics of the components are determined based on the monitoring. The performance characteristics of the service are compared to the service level agreement to determine whether the service level agreement has been violated. At least one of the service or an additional service collocated with the service is migrated based on the performance characteristics of the components if the service level agreement has been violated.
Abstract:
A method and apparatus for recreating a system state in a non-deterministic distributed computing system. A message generated by a message producer is received during debugging. If the received message matches a stored message in a persistent message store, the received message is transmitted to a message consumer. If the received message does not match the stored message, the stored message is transmitted to the message consumer.
