Abstract:
1. A method in a data processing system, for managing and balancing load across multiple managed systems in a logical partitioning data processing system, the method comprising: responsive to a first logical partition requiring additional data processing resources in a first managed system, determining whether one or more managed systems have available resources to satisfy resource requirements of the first logical partition, wherein the first logical partition is marked as critical and not eligible for partition migration; responsive to determining that the one or more managed systems have available resources to satisfy resource requirements of the critical partition using a combination of partition migration and dynamic logical partitioning, performing at least one partition migration operation to migrate a second logical partition from the first managed system to a second managed system within the multiple managed systems, wherein the second logical partition is marked as eligible for partition migration; and responsive to the at least one partition migration operation, performing at least one dynamic logical partitioning operation to allocate utilized processing resources resulting from the at least one partition migration operation and resources from a third logical partition in the first managed system to the first logical partition, wherein the third logical partition is marked as non-critical.
