Abstract
Abstract According to one embodiment of the present invention, a transaction processing system is provided comprising at least one server and a mainframe. Recovery process for restarting a batch is also provided comprising failure detection process for indicating a batch failure, and a startup means responsive to the failure detection process for starting failed batch on the mainframe. In a particular embodiment of the present invention, a batch failure may be indicated by a server's failure to respond to a request or by a step within a batch requiring longer than a predetermined length of time to complete. Further, in alternative embodiments of the present invention, recovery process may run on the mainframe, the server processing the batch, or a secondary server.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
134 words
A transaction processing system for processing transactions and providing failure detection and recovery comprising: a mainframe computer; at least one remote server, said at least one remote server in communication with said mainframe computer; said at least one remote server processing transactions sent by the mainframe computer; recovery means for detecting a failure occurring on said at least one remote server and for restarting said transactions affected by said failure; wherein said recovery means comprises a failure detection means for detecting failures occurring upon said at least one server and a startup means for restarting said transactions affected by said failure; wherein said failures comprise batch failures and remote server failures; and wherein said failure detection means indicates a failure when the processing of said batch requires longer than a predetermined amount of time.
Claim 2
Dependent Claim
134 words
A transaction processing system for processing transactions and providing failure detection and recovery comprising: a mainframe computer; at least one remote server, said at least one remote server in communication with said mainframe computer; said at least one remote server processing transactions sent by the mainframe computer; recovery means for detecting a failure occurring on said at least one remote server and for restarting said transactions affected by said failure; wherein said recovery means comprises a failure detection means for detecting failures occurring upon said at least one server and a startup means for restarting said transactions affected by said failure; wherein said failures comprise batch failures and remote server failures; and wherein said failure detection means indicates a failure when the processing of said batch requires longer than a predetermined amount of time.
Claim 3
Dependent Claim
20 words
The transaction processing system of claim 1 wherein said transactions affected by said failure are restarted on said mainframe computer.
