ABSTRACT:
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.
