Mechanisms are provided for performing a live update of an operating system. The mechanisms receive an update to an operating system and clone a root volume group associated with an operating system instance executing in a first logical partition of the data processing system to generate a cloned root volume group. The mechanisms apply the update to the cloned root volume group to generate an updated and cloned root volume group and boot a second logical partition of the data processing system using the updated and cloned root volume group. Moreover, the mechanisms migrate application instances and application data to the second logical partition.

Live operating system update mechanisms

A method for generating a new configuration of a program containing a plurality of modules and stored in a data processing system. A first table built in response to data entered by a user at a workstation contains the correspondence between each program function and an assigned user. A second table built in response to requests for creating or modifying specified functions indicates for each request, a request number, a description of the requested work, and the function assignee retrieved from the first table. Then, a message is sent to a function assignee that contains the request number and description of the requested work. A third table built in response to users starting the work requested contains for each request number, a status for the requested work. By reading the third table, a report of the status of the requests is prepared which helps the program administrator to prepare a new configuration of the program.
