Top command broken in terminal

OK, the 'top' command in terminal has been broken since I started using Mac OS X. The interactive key commands simply are ignored. Apple needs to fix this, or update the man page to correctly reflect these limitations. For example, typing '?' is supposed to display help information, but does nothing.
In addition, on my MBP the top command itself seems to use about 40% of the cpu, which is absurd.

Yes, there are Hosts, but they are very few and have to sift through thousands of posts (mostly looking for those that are abusive or otherwise inappropriate). So it's unlikely that your comment will be seen. The feedback forms are the best way to get comments directly to Apple (and no, you won't get a response, but that doesn't mean that the comments aren't read).

Running Top command in Java

hi friends,
when i run Top command in Linux from java by using Runtime.getRuntime.exec(), it is giving the following error---
top: tcgetattr() failed : Invalid Argument
While this command is working properly from shell.

command is working properly from shell.top needs a terminal to run; it's a silly and ugly little program. When you
fire up a process using the exec() method you don't have a terminal
environment for the process. Try to run 'ps' instead.

How to see rest of output of TOP command

launch Terminal
run the top command
how to view the rest of its output ?
yeah resizing the window helps. But it still wont show all.
Best to you !

Use Applications -> Utilities -> Activity Monitor ?
The 'ps' command ?
top -l 100 # that is lowercase L - see "man top"

Total RAM as seen from top command is 12G.
*2569836* - Total RAM which is being used currently .
How can I see the total RAM used by all Oracle Processes running in this server. The server is Linux X86 64 Bit. Can I sum up the values under 'VIRT' column of 'top' command to see the total RAM used ?
Is there a way to see the total RAM and CPU used by Oracle from top ?
'VIRT' is the virtual memory - In what way is this related to the figure above, which is the physical memory (RAM) ?
Thanks in Advance

Oracle used shared memory to implement the SGA, which constituted the largest memory consumption of the Oracle instance. The problem is that in many modern OS, including linux, it is hard to define the actual memory usage fo a software. This is because the memory used by a process is actually composed of shared (e.g., shared memory, shared library, executable code) and private (e.g., the heap, the stack) components. Utilities like top, ps, etc reports all memory visible by a process, disregarding whether it is shared or not. As a result, the total of VIRT etc will be inflated by the shared components. For a more accurate figure of memory usage, shared memory / library / code should be counted once.
Before 11g, Oracle used System V ipc, and the amount of memory allocated can be checked using ipcs. In 11g, Oracle switched to /dev/shm, use df to check the memory allocation. (Thanks user11150436)
The "Mem used" figure in top is the actual usage of the memory: shared memory and library are not multi-counted. However, Linux will always cache (read before actually requested) and buffer (write after signalling completion) disk I/O. Therefore, "Mem used" is almost always very close to the amount of physical memory. "Mem used" - "buffers" - "cached" reflects the memory actually used by the OS and all programs more accuately.
And you can use the pmap utility to check the memory map. Then you classify the sharable and unsharable memory usage to calculate a more accurate result suiting your need. You need OS knowledge to understand the output.

How to find the contents of proc from top command

Top has two sections, the summary information at the top of the screen which gives load averages, process counts, etc. and a bottom section which lists the "top processes". The prstat command standard report is similar to the bottom section of top. So if that is what you need, then prstat is an adequate substitute. It doesn't report the information in top's summary section. On the other hand, prstat is actually a much more powerful tool than top, especially is you use some of the other options. For example, "prstat -a" gives you the "top process" report plus a summary report of usage by user. If you use "prstat -J" you get a top process report with a summary by project and "prstat -Z" gives a top process report with a summary by zone. You can use options like -v or -m to get more information on each process in the "top process" section. There are other options mentioned in the manual page.
Top works and works well on Solaris. You can get a copy form sunfreeware and probably other sources as well. It doesn't come from Oracle with Solaris 10 (but does come with Solaris 11). If you're a Linux shop you might want it because it is familiar. However, you may want to look at prstat as well because it can provide some useful information that top does not.

a short and correct answer would be: you can't.
As oracle uses a fair amount of shared memory, and that shared memory is attached to most of the oracle processes, the same memory appears a number of times.
you should rephrase your question / what is it you want to achieve?
you can ask oracle how much memory is assigned to it, v$sga, v$sgastat, v$process (for PGA). moreover, you as DBA are the one who configured that.
you can look at major an minor faults per process to see what is causing the paging (if you have any).
you can also look at the /proc/pid/statm pseudofilesystem for your oracle pids.

Output of "top" command

i can't understand the CPU usage in top command. even the man page does not describe the necessary options. here is what i have from the "top":
Cpu(s): 3.7%us, 1.0%sy, 0.0%ni, 95.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
how will i know which option represents the CPU in use and which represents free CPU ? (i mean the meanings of us, wa, id and sy )
also, what is the difference between VIRT, RES and SHR memories. which one represents RAM ?

us is processor time used by userspace processes, sy by kernel, ni by niced processes, id means idle, wa denotes waiting for I/O, hi and si are hard/soft interrupts.
Read "man top" for VIRT etc. descriptions.

Top command in oracle

hi! i want to know about the top command used in oracle , Please if some body can send relevant information then i will be highly obliged

Past few days I am getting crazy by reading question on this form. Someone recently asked that, apart from dedicated and shared mode, there is another type of mode database available in oracle. It really drives me crazy and now, someone ask TOP.
Whoever asking question, should be more clear about his doubt. They simple ask short question and expect optimal answer. And the topic prolongs by asking what is your OS, what is your oracle version, when you are getting this error and etct. stuff.
The one who is asking question, he should first be clear in his doubts, and search or google for an answer and still he has doubt, he can express all his doubts. In this way, one can learn manything.
