OverviewIntroduction to PRM commands Why use HP Process Resource Manager? Balancing resource use between users Standard HP-UX resource allocationHow PRM can improve on standard allocation Resources managed by PRMPrioritizing resource use between users Prioritizing resource use for applicationsLimiting resource consumption Isolating resource use for applications and usersPRM groups Understanding how PRM manages resourcesHow PRM controls resources How processor sets work? Resource allocationWhat are processor sets? Processor sets exampleHow shares work Altered configurationWhat are shares? Converting shares to percentagesHierarchical PRM groups Parent, child, sibling, and leaf PRM groupsHierarchical PRM groups-top level Hierarchical PRM groups-Development’s child groupsHow PRM manages CPU resources Example PRM CPU resource management PRM CPU resource managementCPU allocation and number of shares assigned Capping CPU resource useMultiprocessors and PRM How PRM manages CPU resources for real-time processesHyper-Threading How PRM manages real memory resources How HP-UX manages memoryExample of available memory on a 1024-Mbyte system Available memoryHow PRM controls memory usage Implementation of shares and caps Reducing memory sharesCapping memory use How PRM manages locked memory Isolating a group’s private memory resourcesHow PRM manages shared memory Example memory management Locked memory distributionHow resource allocations interact How PRM manages applicationsPRM’s group assignments at process start-up How PRM handles child processesPattern matching for filenames Pattern matching for renamed application processes Opt/specialapps/bin/*GroupSPrecedence of PRM group assignments Bar MyfavoriteappPrmrun -g GroupA barnone PhonehomeUnderstanding how PRM manages resources Selecting a configuration model PRM configuration planningUsing multiple configurations Budget model configurationsApplication priority model configurations MEM Identifying resource use Quick analysisDetailed analysis Using prmanalyze to quickly identify resource use Initial configuration based on prmanalyze’s memory report Initial configuration based on prmanalyze’s CPU report#prmanalyze -s command -r mem -p -t summary -1filename 25% Setting PRM to start automatically at reboot Setting up PRMInstalling PRM Installing PRM Setting PRM to start automatically at reboot#/opt/prm/bin/prmsmhconfig -c Using PRM with HP System Management Homepage SMHQuick start to using PRM’s SMH interface #ps -efP What PRM tasks are available through SIM?
