Solaris Tips : CPU Cache Sizes, Changing System Date
By Giri Mandalika on Dec 28, 2012
Tip #1: Finding the CPU cache sizes from Solaris operating environment
prtpicl utility to list out system configuration, and look for the cache sizes within that output.
$ /usr/sbin/prtpicl -v |grep cache :l1-icache-size 0x10000 :l1-icache-line-size 0x40 :l1-icache-associativity 0x2 :l1-dcache-size 0x10000 :l1-dcache-line-size 0x40 :l1-dcache-associativity 0x2 :l2-cache-size 0x500000 :l2-cache-line-size 0x100 :l2-cache-associativity 0xa
[Updated 01/14/13] The above output was gathered from an M4000 system that has SPARC64 VII processors.
Recent update releases of Solaris 10 and 11 show the
prtpicl reported cache sizes in decimal numbers.
Here is a slightly improved
prtpicl command that filters out unwanted output. (Courtesy: Georg)
/usr/sbin/prtpicl -v -c cpu | egrep "^ +cpu|ID|cache"
Tip #2: Changing the System Date
date to change the system date. For example, to set the system date to March 9, 2008
08:15 AM, run the following command. Syntax: date mmddHHMMyy
#date 0309081508 Sun Mar 9 08:15:03 PST 2008
