    摘要： A method and system for implementing a Restart Service for the Object Transaction Service are described. The present invention provides a method and system which trigger restart of an OTS instance upon system recovery or upon system failure. The Restart Service runs independently of the client or server processes which it restarts. When a client or server enters a pending state for a transaction, a permanent record containing information to allow the OTS instance to be restarted is stored in a Restart Repository. In the event of system recovery being needed, or of a system failure, a Restart Daemon reads information from the Restart Repository and recreates the process context. The Recovery Service is initialized and log data replayed to a Transaction Manager to determine the outcome of pending transactions. Failed objects and instances of the OTS are restarted.

    摘要翻译： 描述用于实现对象事务服务的重新启动服务的方法和系统。 本发明提供一种在系统恢复或系统故障时触发OTS实例重启的方法和系统。 重新启动服务独立于重新启动的客户端或服务器进程运行。 当客户端或服务器进入事务的挂起状态时，包含允许重新启动OTS实例的信息的永久记录被存储在重新启动存储库中。 在需要系统恢复或系统故障的情况下，重新启动守护程序从重新启动存储库读取信息并重新创建进程上下文。 恢复服务已初始化，并将日志数据重播到事务管理器以确定待处理事务的结果。 失败的对象和OTS的实例将重新启动。

    摘要： The invention provides a mechanism to integrate differing transaction protocols by augmenting an existing Resource Manager to act as both a Transaction Manager and a Resource Manager within a system which also contains a standards-based Transaction Manager which has overall transaction management responsibility. The Transaction Manager within the Resource Manager acts as an interface to provide specific mappings between the Transaction Manager which has overall transaction management responsibility and a proprietary transaction processing system which it manages. The interface is required to map different transaction identification specifications, record appropriate state information and have procedures to effect failure and restart scenarios.

    摘要： In a data processing environment where a client requests a server to perform part of its processing, a method of updating the client's version of server-related data without requiring the client to be a server, includes steps of: receiving, at a control point server, a first request from the client requesting that server-related data be transferred from the control point server to the client; and in response to the first request, sending the server-related data from the control point server to the client, along with a unique bind token identifying a version number of the server-related data such that each time the server-related data changes a new unique bind token is associated with the data, where the client uses the server-related data to form a second request for the server to perform part of the client's processing, and where the client sends said bind token to the server as part of the second request.

    摘要： The invention allows the participation of a resource manager in a transaction which is coordinated by a transaction manager with which the resource manager's protocols are not compatible. More particularly, a mapper records a connection reference which the application program obtains from the resource manager and a transaction reference which the application program obtains from the transaction manager. The resource manager stores recovery information in an associated log file.
