  • Patent number: 8055733
    Abstract: Hardware and partition information of an existing LPAR system is collected and stored in a first system plan file. The first system plan file is applied to a partition planning tool. The partition planning tool identifies hardware to be reused in a second LPAR system and filters hardware to be excluded from the second LPAR system. The partition planning tool creates a plan for the second LPAR system using the identified hardware to be reused and the partition information. The created plan for the second LPAR system is applied to a partition deployment tool to partition the second LPAR system. The created plan for the second LPAR system is used to move and place hardware to be reused in the second LPAR system.

  • Patent number: 8037059
    Abstract: A process combines multiple grouping sets into single rollup sets with depth lists defining the levels of grouping that must be performed. Grouping sets are identified that are contained within other sets and combined into single rollups with depth lists. Cube aggregation conversion to rollup aggregation is provided for optimizing database query processing. Natural sets of rollup hierarchies within a cube are recognized and the cube is converted into those rollup hierarchies. Once converted, the rollup aggregation is performed to significantly reduce required processing.

  • Patent number: 7954642
    Abstract: An elutriation column is installed in a separation tank. The elutriation column includes a vertical separation column having a first side feed arm and a second side overflow arm spaced above the first side feed arm. Water is forced upwardly through the vertical separation column at a controllable velocity. A solid feed mixture is fed through the first side feed arm to the vertical separation column. Water from the tank rising in the vertical separation column at the controlled velocity causes targeted floater materials to move upwardly in the vertical separation column and heavier sinker materials to continue to sink. The floater materials flow from an outlet in the side of the separation tank into the recovery tank. At a discharge, lower end of the vertical separation column, the heavier sinker materials are removed from the separation tank. A mechanism is provided for purging undesirable materials that can cause plugging from the feed arm.

  • Patent number: 7941652
    Abstract: A method, apparatus and computer program product are provided for implementing atomic data tracing in a processor system including an auxiliary processor unit (APU) coupled to a central processor unit (CPU). The auxiliary processor unit (APU) processes a trace instruction. When a trace instruction is identified by the APU, the APU signals the CPU with a pipeline stall signal for stalling the CPU and checks for an enabled trace engine as specified by the trace instruction. When the trace engine for the trace instruction is enabled, then the trace data is written into a trace buffer. The APU signals the CPU with an op done signal for allowing the CPU to continue with instruction processing.
