Abstract: 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.

Abstract: A system and method are disclosed for verifying connection characteristics of a connection-oriented transmission pathway. A receiver of a network device is configured to receive a data stream from a source network device over the pathway. The data stream including a header portion and a data portion. In response to detecting the header portion, a processor of the network device counts a number of units of data received in the data portion and measures a time span over which the data portion is received. Then a transmitter of the network device sends a response data stream, including the count of the number of units received and the measured time span, to the source network device. The source network device determines an actual bandwidth of the connection-oriented transmission pathway using these values.

Abstract: Asynchronous connection-oriented transmission network of the (ATM) network type comprising a plurality of switching nodes (12, 14, 16, 18) interconnected by connection lines, each of these switching nodes being associated with a control point in charge of determining the best route between any source node (12) and any destination node (18) when a connection has to be established therebetween by identifying which ones of the connection lines are eligible based upon the requirement of a quality of service.

Abstract: 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.
