Re: OT : kernel using 75% of CPU

Does anybody know how I can see how much memory each process is using under Solaris. On Digital UNIX it was ps -aux, if I remember correctly...
 
Thanks!

  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,

      OT : kernel using 75% of CPU
      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:

      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!
