Abstract: A method and system for implementing a replica network configuration in a distributed system is provided. The system includes a memory having computer readable instructions, and one or more processors for executing the computer readable instructions. The computer readable instructions include generating a replica node that is assigned a computer readable storage medium and a processor, receiving, at the computer readable storage medium, a network configuration of the replica node from a system administrator, automatically generating, using the processor, a unique identifier (UUID) for the replica node, transmitting the UUID to a plurality of replica nodes of the distributed system arranged in the replica network configuration, and storing the UUID in the computer readable storage medium, wherein the computer readable storage medium is a persistent storage.

Abstract: For passive detection of live systems during controller failover in a distributed environment, a set of member systems is sorted according to heartbeat periods used by members in the set of member systems. An amount of elapsed time since a failure of a first controller system in the distributed environment is determined. From the sorted set, a first member system is selected due to a first heartbeat period of the first member system being a shortest heartbeat period in all heartbeat periods in the sorted set of member systems. Using a processor and a memory at a second controller system, a timeout period is computed. The timeout period is an amount of time remaining in the first heartbeat period after the amount of elapsed time. The first member system is removed from the sorted set after the timeout period expires and the first member system has not sent a heartbeat.

Abstract: Systems (100) and methods (200) for managing transactional processing. The methods involve executing a first transaction (120) which is blocked by an exclusive lock of at least one second transaction (110) from accessing at least one resource of a system. Thereafter, a determination is made as to whether a Service Level Agreement (“SLA”) associated with the first transaction is being met. If it is determined that the SLA is not being met, the resources needed by the first transaction are identified. Subsequently, all executing transactions, that are using the resources needed by the first transaction, are identified. At least one of the identified transactions is then dynamically slowed down or speed up. The transaction is slowed down or sped up by: adjusting how many records are to be processed in each sub-transaction of the transaction; and/or increasing or decreasing the time period between commit operations of the transaction.

Abstract: A batch data stream, which comprises inputs to a serial batch application program, is received. Batch code from the serial batch application program is translated into parallel code that is executable in parallel by multiple execution units. Checkpoints are applied to the batch data stream that has been received, and data between the checkpoints defines multiple threads. The multiple threads are stored in an input queue that feeds data inputs to multiple execution units. The parallel code is then executed in the multiple execution units by using the multiple threads as inputs.

Abstract: A method for hosting versioned web services includes steps of: receiving a request from a service requestor, the request comprising version metadata; parsing the request; extracting the version metadata from the parsing step; and locating a target implementation version using the version metadata. If the target implementation version is located, the method proceeds by dynamically routing the versioned request to the target implementation version.

Abstract: An exemplary embodiment of the invention relates to a method, system, and storage medium for providing context-based dynamic policy assignment in a distributed processing environment. The system includes a first resource management host in communication with a client system, an application executable by the first resource management host, a dynamic policy assignment system executing on the first resource management host, policies stored on the first resource management host and an application profile associated with the client system. The application profile is received by the first resource management host. Application hosting services include executing the application on behalf of the client system. The dynamic policy assignment system receives the request, and based upon a task name associated with the application profile, selects at least one policy for an application instance.

Abstract: Methods and systems are provided for conducting maintenance such as software upgrades in components and nodes within a computer network while maintaining the functionality of the computer network in accordance with prescribed performance parameters. A balance is achieved between the rate of performing a desired system upgrade and the necessary performance parameters by empirically determining anticipated system loads and selecting the maximum number of components that can be upgraded simultaneously while meeting the anticipated loads. Provisions are made for the staggering of components through the upgrade process and for the return of components to active service in the computer network in response to unanticipated load spikes. Validation of successful upgrades is also provided.

Abstract: A system and method for providing a reusable connection handle to managed connections within transactions, or other scoping mechanisms, preferably in a Java 2 Enterprise Edition (J2EE) software architecture on a computer platform. The system and method further allows for multiple connection handles to share the same managed connection within, but not outside of, the confines of the scoping mechanism. The connection handle is selectively disassociated from a managed connection whereby the connection handle enters a disassociated state, and then is selectively reassociated with a managed connection within the software architecture when desired.
