Yes and no. You won't have to rebuild the kernel (in the normal sense of the term), but you will have to reboot.

The parameters are in '/etc/system'; you will need to do some best guessing and a little figuring to come up with some varibles - it depends on your database size and memory your platform has.

For example, the following is from the '/etc/system' on my Solaris 2.3 machine. I'm running 7.1.6, and have two instances; my SUN has 128Mb of RAM...

• set test_module:debug = 0x13

	set semsys:seminfo_semmni=70
	set semsys:seminfo_semmns=200
        set shmsys:shminfo_shmmax=41943040
	set shmsys:shminfo_shmmni=100
	set shmsys:shminfo_shmseg=10
	set shmsys:shminfo_shmmin=1

You may need/want to fiddle with it a bit and see what gives you the best performance.
