  • Publication number: 20130174136
    Abstract: An approach is provided in which a computer system receives a request to utilize a locale package for which to display information on a display. The computer system determines that the locale package is not installed on the computer system's operating system and, as such, sends a request to a locale service for a locale source file. The computer system receives the locale source file from the locale service and utilizes the received locale source file to generate the locale package. In turn, the computer system installs the generated locale package on the operating system.

  • Patent number: 6829714
    Abstract: A method and system for providing a timed power-on of logical partitions in a logical partition computer system is disclosed. An operator is allowed to enter a timed power-on value (TPO) value representing a time to boot one or more of the logical partitions. The TPO value for each of the logical partitions is then stored in nonvolatile memory. The system time is then periodically compared with each of the TPO values, and the corresponding partition is booted when the system time is greater than or equal to the TPO value.

  • Patent number: 6651182
    Abstract: A method, system, and apparatus for recovering system resources to provide a minimum system configuration in a data processing system is provided. In one embodiment, a firmware component within the data processing system, during initial program load, determines that a first resource has failed. The first resource is then deallocated. Responsive to a determination that deallocation of the resource has resulted in less than the minimum system configuration for operation of a data processing system, the firmware component determines which of a plurality of deallocated resources suffered from the least severe failure. The one of the plurality of deallocated resources that suffered from the least severe failure is then reallocated for use by the data processing system.

  • Patent number: 6460005
    Abstract: An apparatus and method for monitoring environmental conditions in a computing device is provided. After collecting the initial value of each environmental sensor, a processor calculates the difference between the current value and the next warning/critical level value. The processor instructs an environmental sensor controller to report new sensor measurements only when the sensed value changes by at least a half of the difference between the current value and the next warning/critical level value. Upon receipt of a new sensor value from the environmental sensor controller, the processor adjusts the reporting threshold by re-calculating the difference between the current sensed value and the next warning/critical level value. This process of reporting threshold adjustment continues until the sensor value is within a danger zone. Once the sensor value is within the danger zone, the processor will set the reporting threshold to a minimum allowed for the particular environmental sensor type.
