Overview Introduction 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 PRM Prioritizing resource use between users Prioritizing resource use for applications Limiting resource consumption Isolating resource use for applications and users How PRM controls resources Understanding how PRM manages resourcesPRM groups How processor sets work? Resource allocationWhat are processor sets? Processor sets example How shares work Altered configurationWhat are shares? Converting shares to percentages Hierarchical PRM groups Parent, child, sibling, and leaf PRM groups Hierarchical PRM groups-top level Hierarchical PRM groups-Development’s child groups How PRM manages CPU resources Example PRM CPU resource management PRM CPU resource management CPU allocation and number of shares assigned Capping CPU resource use Hyper-Threading How PRM manages CPU resources for real-time processesMultiprocessors and PRM How PRM manages real memory resources How HP-UX manages memory How PRM controls memory usage Available memoryExample of available memory on a 1024-Mbyte system Capping memory use Reducing memory sharesImplementation of shares and caps How PRM manages shared memory Isolating a group’s private memory resourcesHow PRM manages locked memory Example memory management Locked memory distribution How resource allocations interact How PRM manages applications Pattern matching for filenames How PRM handles child processesPRM’s group assignments at process start-up Pattern matching for renamed application processes Opt/specialapps/bin/*GroupS Precedence of PRM group assignments Bar MyfavoriteappPrmrun -g GroupA barnone Phonehome Understanding how PRM manages resources Selecting a configuration model PRM configuration planningUsing multiple configurations Budget model configurations Application priority model configurations MEM Identifying resource use Quick analysis Detailed analysis Using prmanalyze to quickly identify resource use #prmanalyze -s command -r mem -p -t summary -1filename Initial configuration based on prmanalyze’s CPU reportInitial configuration based on prmanalyze’s memory report 25% Setting PRM to start automatically at reboot Setting up PRMInstalling PRM Installing PRM Setting PRM to start automatically at reboot Quick start to using PRM’s SMH interface Using PRM with HP System Management Homepage SMH#/opt/prm/bin/prmsmhconfig -c #ps -efP Configuring user authorizations Using PRM with HP Systems Insight Manager SIMWhat PRM tasks are available through SIM?
