Our Solaris 10 Sun server has 16 x 2.02Gb cpus with 80Gb memory. It
runs Oracle 10g, Websphere 6.0, JVM, Veritas 4.1 and a 3rd party
software. The data resides in a Hitachi mid-range enterprise storage
array. We notice that the "mjf" column in "mpstat" command is
consistently very high among different cpus. What may be the cause ?
Is there any way we can trouble-shoot and resolve this ? Thanks,
Bill


$ mpstat 5 5
