Described herein is a system for executing distributed transactions. A participant and a coordinator cooperate to execute a distributed transaction, the distributed transaction including a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. The distributed transaction may be terminated when communication between the participant and coordinator regarding the transaction does not occur within a time period. The time period may reflect the time required for a coordinator to send a message and a participant to acknowledge receipt of the message, and the time for the participant to perform operations executed for the transaction. The latency of network traffic between the participant and the coordinator is monitored, and the time periods adjusted accordingly. In addition, the amount of time required for the participant to execute operations for the transaction is monitored, and the time periods adjusted accordingly.

An efficient fault-tolerant event ordering service as well as a simplified approach to transaction processing based on global event ordering determines the order of interdependent operations in a distributed system. The fault-tolerant event ordering service externalizes the task of tracking dependencies to capture a global view of dependencies between a set of distributed operations in a distributed system. A novel protocol referred to as linear transactions coordinates distributed transactions with Atomicity, Consistency, Isolation, Durability (ACID) semantics on top of a sharded data store. The linear transactions protocol achieves scalability by distributing the coordination task to only those servers that hold relevant data for each transaction and achieves high performance by serializing only those transactions whose concurrent execution could potentially yield a violation of ACID semantics.

Various embodiments of a cluster of application servers in a networked computer system in which each application server includes a separate transaction manager instance are disclosed. In one embodiment, a separate transaction manager instance may be used to coordinate transactions initiated by an application component executing in process with the application server for a node of a cluster.

Further, if each transaction manager instance maintains its transaction logs in highly available memory accessible to all nodes of the cluster, in flight transactions of a failed node may be recovered by an instance in a different node.

The present invention provides systems and methods for conducting electronic transactions in a distributed computing environment. A communications protocol is provided that enables reliable transactional state synchronization for peers participating in a distributed transaction. A transaction processing application is deployed on a local computer system to manage transactions thereon. The local computer system contacts a remote computer system to obtain authorization to execute a transaction. The local computer system initiates a failure-recovery job that is operable to automatically resend status signals and other information to the remote system if the communication with the remote system exhibits certain predefined fault conditions. The remote system is able to dynamically adjust the definition of the predefined fault conditions. If the transaction concludes without triggering the predefined fault conditions, the failure-recovery job is cancelled. The transaction processing application may also allow deferred transactions between remote parties. The transaction processing application maintains a record of the transactions performed by the consumer on the consumer's local system. Upon the occurrence of predefined conditions, transactional records are sent to a remote vendor or clearinghouse. The vendor or clearinghouse can manage the risk it bears by setting the predefined conditions appropriately.

A system and method is shown for enabling a plurality of computers and associated computer resources, some or all of which may be of heterogeneous configuration, to cooperatively process various applications such that the execution is transparent to the user regardless of where the application is actually executing. This distributed applications architecture performs an information distribution service between multiple transaction processing systems by working with a transaction processor via communication channels to other hosts within the network and a dialog manager which uses a transaction processor interface to communicate with the transaction processor. The architecture employs a map service which provides an editor to create the maps for the application panels, a compiler to generate the maps into a linkable form, and a linkable interpreter which translates the linkable form into the screen presentation format for that platform. To distribute an application, the source code for the procedures, view and panels are moved as a block to the new system. This is possible because once the application source code is complete, all application logic, user interface control tables, view definitions, and other application-specific tables for one transaction definition are packaged by the present invention in a single load module on the system where the application will reside. The load module is then compiled using the target system's compiler, link editor, and bind process. Thus, all environment-dependent variations of import / export are automatically integrated with the application at load module bind time, requiring no source code changes.

The invention further provides a cross-database distributed transaction implementation device. By means of the method, the cross-database distributed transactions which are lightweight and easy to maintain and meet the ACID principle can be realized.

The present invention provides a method and system for tracing and monitoring of distributed transactions spanning multiple threads or processes, running on multiple host systems, connected by a computer network. The correlation of distributed transactions is based on information that uniquely may identify execution paths within a virtual machine, additional to information which uniquely may identify the virtual machine that processes the execution path. The correlation information is transferred from a monitored thread to threads that are activated by the monitored thread and allows to reconstruct parent-child relations between different threads. Participating threads may run in different processes, in different virtual machines or on different host systems.

A method, system and program are provided for dynamically assigning priority values to instruction threads in a computer system based on one or more predetermined thread performance tests, and using the assigned instruction priorities to determine how resources are used in the system. By storing the assigning priority values in thread priority registers distributed throughout the computer system, instructions from different threads that are dispatched through the system are allocated system resources based on the priority values assigned to the respective instruction threads. Priority values for individual threads may be updated with control software which tests thread performance and uses the test results to apply predetermined adjustment policies. The test results may be used to optimize the workload allocation of system resources by dynamically assigning thread priority values to individual threads using any desired policy, such as achieving thread execution balance relative to thresholds and to performance of other threads, reducing thread response time, lowering power consumption, etc.

Visual image features are extracted from the segments and one-SVM classification is performed on the extracted features to categorize segments into inliers or outliers relative to a threshold boundary. Event of concern alerts are issued with respect to the inlier segments associated with the associated pseudo transaction marker.
