摘要:
The management and use of replicated distributed transactions is facilitated. A distributed synchronous transaction system protocol is provided to manage the replication of distributed transactions for client application instances. The distributed synchronous transaction system allows transactions to be replicated without having the client application instances be aware of other instances to receive the transaction. Further, if a failure occurs during processing of a distributed replicated transaction, the distributed synchronous transaction system manages the recovery of the failure.

摘要:
Threads of a multithreaded client application access data in one or more global data repositories via one or more local trees. Each local tree is associated with one or more locked resources of the global data repository. By using the local trees in accessing the data of the global repository, a thread is automatically associated with a lock block and therefore, the granting of locks is independent of any threading models.
摘要:
A client application sends a request to a given server of a replicated group of servers, and expects a response to the request. If the client does not receive a response to the request, or if the server is otherwise unavailable, the client is automatically reconnected to another server of the replicated group. The servers of the replicated group do not, however, have to have any knowledge of the communication session of the client.

摘要:
At least a portion of a table stored in a global data repository is selected to be accessed and modified. The selected portion is stored in a local table in local memory of a node of a client-server environment. The local table is modified, and then at least a portion of the modified local table is merged with the global table. The merger is performed without requiring any user locking of the global table.
摘要:
Various components are provided to manage a clustered environment. These components include a System Registry that provides a global data storage; a Configuration manager that stores data locally on nodes of the clustered environment and globally within the System Registry; a Liveness component to provide status of communications paths of the cluster; a Group Services component that provides services to one or more other components of the clustered environment; and a Resource Management component that communicates with one or more resource controllers of the clustered environment. Each of the components of the clustered environment has one or more data and/or functional dependencies on one or more other components of the environment. However, relationships between the components are created such that the data and functional dependencies form an acyclic graph (i.e., a cycle of dependency relationships is avoided).
