Thanks for the reply, Chris.
I'm a bit ashamed, being as old as I am, that I don't have a better grasp on swapping. I initially thought maybe it was a swap problem also, but top shows 0.0% swap. I thought I had also checked vmstat earlier, but yikes:

Do the pi (page in) and po (page out) statistics represent swapping?!
Thanks again,

paging and swapping is the first thing that comes to mind, look at vmstat.
I think your question is completely on topic.

Hi there,
I have a Sun e4500, running Solaris 2.7 and Oracle 8.1.7.1.0. Everything looks normal from a database perspective, but when I run "top" it show the kernel being very hog-like:
load averages: 14.38, 15.18, 15.18 07:16:21
126 processes: 118 sleeping, 4 running, 4 on cpu
CPU states: 0.6% idle, 26.6% user, 72.8% kernel, 0.0% iowait, 0.0% swap
Memory: 4096M real, 63M free, 216M swap in use, 5310M swap free

11292 oracle 1 26 2 2008K 1424K run 0:00 0.19% dsql
Any ideas on what I, as a lowly DBA, would be able to check? It's a bit out of my area and I'm stumped...
Thanks!
Jerry
