Hi, It might be useful first to estimate if your current server can sustain the workload you plan to do. You cant simple add applications and then expect things will work the way you want... so you gotta be careful.
Example: how many processes this machine has and how many syscall/s comparing with the mem and no. of CPUs ? $ sar -v 1 10 $ sar -c 1 10 Issues/Check - too many processes for you current hardware ? - I see you run Oracle. How many database instances are you running ? - 2 CPU machine might not be enough for your current workload - 8GB RAM physical might not be enough for your current workload ToDo: - depending on your workload profile you might consider using a T2000 or a faster machine with more CPUs - size your applications. Write down and estimate a bit somehow how much would you expect the memory usage from your apps. Include here the SGA from Oracle - swap: ensure that there is enough backing device for this workload - plan for future: as already mentioned there are some very good references as: The Practical Performance Analyst, Guerrilla Capacity Planning (new published) and Analyzing Computer System Performance with Perl: PDQ to help you to plan and possible predict your workloads. Im as well experimenting with these and found them very useful. - download from: http://www.brendangregg.com/k9toolkit.html sysperfstat it can easily help you understand the big picture Hope it helps, stefan This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
