Abstract

A server processing method for use in a client/server computing system which carries out transactions, includes steps of: receiving a command from a client process to signify the beginning of a transaction; determining whether a local transaction creator exists; and forwarding on the command to another server if a local transaction creator does not exist and for locally creating transaction state data if a local transaction creator does exist.

Claims

1. A server for use in a client/server computing system for executing distributed transactions, comprising:

a local distributed transaction service implementation;

means for receiving either a first designation from a systems management unit designating that the server is not to instantiate a transaction factory object upon server startup, or a second designation from a systems management unit designating that the server is to instantiate a transaction factory object upon server startup; and

means for, upon server startup, instantiating a transaction factory object as part of the local distributed transaction service implementation if the means for receiving has received the second designation and for not instantiating a transaction factory object as part of the local distributed transaction service implementation if the means for receiving has received the first designation.

2. The server of claim 1 wherein said local transaction service implementation is implemented in accordance with the Common Object Request Broker Object Transaction Service standard.

3. A computer program product stored on a computer readable storage medium for, when run on a computer system, implementing a server as claimed in claim 1.

4. The computer program product of claim 3 wherein said local transaction service implementation is implemented in accordance with the Common Object Request Broker Object Transaction Service standard.
