Operating Systems Solaris Sparc Solaris 10 load averages Post 302810691 by jim mcnamara on Wednesday 22nd of May 2013 11:17:37 AM

Not necessarily. A very rough rule of thumb is keep those numbers under 2.0 most of the time. What you need to worry about more is a few individual processes eating lots of cpu.

prstat is your friend for this. What those numbers mean is this:
Assume you are going to the bank to do a transaction. When you get there, how many people are in front of you in the the line? So if you have to keep coming back to the line then how long, on average do you have to wait to get service. As those numbers grow it means you wait longer and longer for service. On systems running databases the db frequently uses a lot of resources, comapred with user processes, but it is designed to optimize the use of those resources. So it is common to see some cpu usage like the ones you have.

What exact performance problem do you have?

Running Solaris Sparc Apps on X86 Solaris

I know that Sun make s a version of Solaris for Sparc platforms and also an x86 (Intel/AMD) release of Solaris. Can an application that runs on Solaris/Sparc also run on a PC running the x86 release of Solaris? Would a different release be required or any re-compling of the application? jim (1 Reply)

NAME
ruptime - Displays the status of each host on a network SYNOPSIS
ruptime [-ar] [-l | -t | -u] ruptime [-ar] [-l | -t | -u] [machinename] The ruptime command displays the status of each host on a local network that is running the rwhod daemon. If machinename is specified, only the status of that machine is displayed. OPTIONS
Includes all users. Without this option, users whose sessions are idle an hour or more are not included. Sorts the list by the load aver- age over 5-, 10-, and 15-minute intervals prior to a server's transmission. The load averages are multiplied by 10 to represent the value in decimal format. Reverses the sort order. Sorts the list by the length of uptime. Sorts the list by the number of users. DESCRIPTION
The status lines are sorted by hostname unless the -l, -t, or -u option is indicated. The status information is provided in packets broad- cast once every 3 minutes by each network host running rwhod. Any activity (such as the power to a host being turned on or off) that takes place between broadcasts is not reflected until the next broadcast. Hosts for which no status information is received for 11 minutes are reported as down. EXAMPLES
To get a status report on the hosts on the local network, enter: $ ruptime Information similar to the following is displayed: host1 up 5:15, 4 users, load 0.09, 0.04, 0.04 host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 (Output may be formatted differently on your system.) To get a status report sorted by load average, enter: $ ruptime -l Information similar to the following is displayed: host2 up 7:45, 3 users, load 0.08, 0.07, 0.04 host1 up 5:18, 4 users, load 0.07, 0.07, 0.04 host7 up 7:43, 1 user, load 0.06, 0.12, 0.11 host3 up 2:28, 0 users, load 0.01, 0.02, 0.03 host4 up 3+01:44, 1 user, load 0.01, 0.02, 0.03 (Output may be formatted differently on your system.) FILES
Indicates data files received from remote rwhod daemons. SEE ALSO
Commands: rwho(1), rwhod(8) ruptime(1)
