UNIX for Dummies Questions & Answers

Hello All

1) The top command gives the CPU usage , together with other details but it does not list out the memory usage for each process ...I know it gives us the aggregate memory used , but I'd like to know the memory used by each process .Is there a way to get this ?


load averages: 2.52, 2.76, 2.42 12:04:08
272 processes: 268 sleeping, 4 on cpu
CPU states: 52.3% idle, 32.1% user, 15.6% kernel, 0.0% iowait, 0.0% swap
Memory: 16G real, 6333M free, 8371M swap in use, 20G swap free

PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND
21940 oracle 17 10 0 0K 0K cpu/2 55.9H 24.15% oracle
23282 oracle 1 31 0 0K 0K cpu/3 2:17 7.77% oracle
10847 oracle 12 59 0 0K 0K sleep 38:44 1.89% oracle


2) When I execute a top command , the value of STATE for some of the processes are listed as cpu/2 or cpu/3 . Does it mean that that process uses the 2'nd CPU or 3rd CPU , respectively ?

3) The STATE value for some of the processes are "sleep" . I know that these processes are ACTIVE and doing smoething but I'm not sure why they have a STATE value of "sleep" .


Thanks for your time ...

BTW , I'm using SunOS 5.9

Thanks...
