Abstract: PROBLEM TO BE SOLVED: To enable a resource managing program to participate in a transaction which has been adjusted by a transaction managing program that can not be used in common to the protocol of the resource managing program. SOLUTION: A mapper 248 records reference regarding a connection that an application program 190 has obtained from the resource managing program 120 and reference regarding a transaction that this application program 190 has acquired from the transaction managing program 145. The resource managing program 120 stores recovery information in a relative log file 320.

Abstract: In a data processing environment where a client 11 requests a server 12 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 13, 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.

Abstract: A method of performing workload management within an object-oriented client/server computing environment wherein one of a plurality of servers is chosen to satisfy a client request based on at least one workload management policy, said method, which takes place within the client, includes steps of: deciding whether a client application program has issued a request for a server to do some work; forming an extended object reference based on said request, said extended object reference having, in addition to a server address field and an object key field, at least one additional field; accessing workload management policy data based on said extended object reference; and selecting one of said plurality of servers based on said accessed workload management policy data.

Abstract: Resource Manager (130) acts as both a Transaction Manager and a Resource Manager within a system which also contains a standards-based Transaction Manager (120) which has overall transaction management responsibility. The Transaction Manager within the Resource Manager (130) acts as an interface to provide specific mappings between the Transaction Manager (120) which has overall transaction management responsibility and a proprietary transaction processing system (250) 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.

Abstract: The invention allows the participation of a resource manager 120 in a transaction which is coordinated by a transaction manager 145 with which the resource manager's protocols are not compatible. More particularly, a mapper 248 records a connection reference which the application program 190 obtains from the resource manager 120 and a transaction reference which the application program 190 obtains from the transaction manager 145. The resource manager 120 stores recovery information in an associated log file.

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 (122) or server processes which it restarts. When a client (122) 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 initialised and log data replayed to a Transaction Manager to determine the outcome of pending transactions. Failed objects and instances of the OTS are restarted.
