Patch level of Solaris machine

As i understand, Patch is a fix to bug in a product.

What is patch level wrt to solaris OS ? How do i know the patch level of a machine ? I have task to compare patch levels of 2 machines running solaris

hi,

cat /etc/release and uname -a (look kernel patch) maybe y help.

you can check the current patch level by doing uname -a
See if your kernel level is lower of that is shown from Sun Microsystems
Solaris 8, 9 and 10 have diff latest kernel patch levels.

Hello

showrev command will show you the kernel/patch level with a release date of some kind on Solaris version up to 9.
