Number of cpu cores

[ddrillich]

Good Day,

How can I find out the number of cpu cores on a Solaris server?

\(ddril00\)\>uname -a
SunOS phsupr62 5.9 Generic_118558-05 sun4u sparc SUNW,Sun-Fire-V240

Regards,
Dan

Either /usr/sbin/prtdiag or /usr/sbin/psrinfo will tell you how many cores as well as a variety of other information.

Thank you Linnorm. Here is what I see. Does it mean I have 2 CPUs each with one core?

\(ddril00\)\>/usr/sbin/prtdiag

Yep, the CPUs section is what you're looking for here. If you had a CPU model with multiple cores you'd see additional ones listed on each line separated by commas.
