Overview Introduction to PRM commands Why use HP Process Resource Manager? Standard HP-UX resource allocation How PRM can improve on standard allocationBalancing resource use between users Resources managed by PRM Prioritizing resource use between users Prioritizing resource use for applications Limiting resource consumption Isolating resource use for applications and users Understanding how PRM manages resources How PRM controls resourcesPRM groups Resource allocation What are processor sets?How processor sets work? Processor sets example Altered configuration What are shares?How shares work 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 How PRM manages CPU resources for real-time processes Hyper-ThreadingMultiprocessors and PRM How PRM manages real memory resources How HP-UX manages memory Available memory How PRM controls memory usageExample of available memory on a 1024-Mbyte system Reducing memory shares Capping memory useImplementation of shares and caps Isolating a group’s private memory resources How PRM manages shared memoryHow PRM manages locked memory Example memory management Locked memory distribution How resource allocations interact How PRM manages applications How PRM handles child processes Pattern matching for filenamesPRM’s group assignments at process start-up Pattern matching for renamed application processes Opt/specialapps/bin/*GroupS Precedence of PRM group assignments Myfavoriteapp Prmrun -g GroupA barnoneBar Phonehome Understanding how PRM manages resources PRM configuration planning Using multiple configurationsSelecting a configuration model Budget model configurations Application priority model configurations MEM Identifying resource use Quick analysis Detailed analysis Using prmanalyze to quickly identify resource use Initial configuration based on prmanalyze’s CPU report #prmanalyze -s command -r mem -p -t summary -1filenameInitial configuration based on prmanalyze’s memory report 25% Setting up PRM Installing PRMSetting PRM to start automatically at reboot Installing PRM Setting PRM to start automatically at reboot Using PRM with HP System Management Homepage SMH Quick start to using PRM’s SMH interface#/opt/prm/bin/prmsmhconfig -c #ps -efP Using PRM with HP Systems Insight Manager SIM Configuring user authorizationsWhat PRM tasks are available through SIM?
