top command question
Hi,
I am using the top command and getting the following value in the bottom. I am trying to see the memory usage for this proces. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 23175 javackk 23 0 1281m 302m 25m S 9.9 2.6 397:35.40 /usr/java/jdk1.5.0_ What is VIRT and RES represening? It means 1281M memory is allocated for this process and using only 302 M? Please correct me. |
"man top" gives a description of all the fields. I don't totally understand linux memory management, so I won't presume to explain it.

I read it, but I am not unserstanding it. That's why I want the explanation,.

Here is what man says (I'm not sure what you don't understand):
Code:
VIRT -- Virtual Image (kb) The virtual image is the total of all the memory used by the task, both physical AND swap. HTH Forrest |
