Introduction to PRM commands Why use HP Process Resource Manager? Resources managed by PRM Standard HP-UX resource allocationHow PRM can improve on standard allocation Balancing resource use between users Prioritizing resource use for applications Prioritizing resource use between users Isolating resource use for applications and users Limiting resource consumption How PRM controls resources Understanding how PRM manages resourcesPRM groups Processor sets example Resource allocationWhat are processor sets? How processor sets work? Converting shares to percentages Altered configurationWhat are shares? How shares work Parent, child, sibling, and leaf PRM groups Hierarchical PRM groups Hierarchical PRM groups-Development’s child groups Hierarchical PRM groups-top level How PRM manages CPU resources PRM CPU resource management Example PRM CPU resource management Capping CPU resource use CPU allocation and number of shares assigned Hyper-Threading How PRM manages CPU resources for real-time processesMultiprocessors and PRM How HP-UX manages memory How PRM manages real memory resources 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 Locked memory distribution Example memory management How PRM manages applications How resource allocations interact Pattern matching for filenames How PRM handles child processesPRM’s group assignments at process start-up Opt/specialapps/bin/*GroupS Pattern matching for renamed application processes Precedence of PRM group assignments Phonehome MyfavoriteappPrmrun -g GroupA barnone Bar Understanding how PRM manages resources Budget model configurations PRM configuration planningUsing multiple configurations Selecting a configuration model Application priority model configurations MEM Quick analysis Identifying resource use 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% Installing PRM Setting PRM to start automatically at reboot Setting up PRMInstalling 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?
