A method and system for permitting reversible installation of software applications in a data processing system which includes a processor, memory containing a first version of a selected software application and a storage system for receiving a removable storage medium. A removable storage medium which includes at least one alternate version of a selected software application is inserted into the storage system and a user is then prompted to select an alternate version of the selected software application for installation within the data processing system. The existing version of the selected software application within the data processing system is then automatically copied from memory to the removable storage medium prior to initiation of installation of the alternate version of the selected software application in response to a selection of the alternate version, such that the installation may be selectively reversed. A directory within the removable storage medium is automatically created and updated each time an application is copied from or to the removable storage medium with a listing of each alternate version of the selected software application, a required hardware level for utilization with each version of the selected software application and a listing of each data processing system within the enterprise which has utilized that version.

Method and system for reversible installation of software applications in a data processing system utilizing an automated archival process

A system for the automated isolation and report of a Field Replaceable Unit (FRU) and/or a Replaceable Component (RC) responsive to a stream of Fault Symptom Code (FSCs) produced in response to a system fault. The process is entirely automated and can be stored in microcode to allow immediate updating of FSC to FRU/RC correspondences responsive to system design revisions. Selected FRU/RC isolation procedures are included in the FRUs/RCs for automatic execution as part of the isolation process. Failure probability data, including probability distribution data, are included in each FRU/RC to support an alternative weighted failure probability (WFP) isolation scheme to isolate a faulty FRU/RC even when the automated isolation procedures do not provide an unambiguous result.
