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.

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

Edited by: SSNair on Oct 21, 2010 2:39 AMOracle 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 memory taken by Oracle processes using top command

The different Oracle processes could be Oracle database, Oracle listener, Oracle enterprise manager etc.
I hope, my question is clear as to how to find the memory taken by a process using top command.
Please revert with the reply to my query.
Regardsa 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. -

Question on top command output in solaris
Platform : Solaris 5.10
In the top output, if you look at the CPU colum, you can see that one process (2415) is consuming 95.84 % of CPU, another process (28533) is consuming 91.81%. How can this happen ? If one process is consuming 95.84 , then less 5% of CPU is available to all other processes . Right?

Does "top" command work in Solaris?

top: not found
Edited by: user11936985 on Aug 29, 2011 8:44 AMTop 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. -

Is that something that can be done in Oracle in the same way?
Do you use another approach?
please advice

Why it is showing the Memory Free is 26 MB only...
Only one Database is running on this Machine SGA is around 600MB only.....
Why it is showing 26 MB Free of memory ....Can anybody please describe the TOP Command output.....Hi, this doest look too good... " Swap: 8191992k total, 160k used"
this means you'r using some of you'r swap, "25708k buffers" and not becouse of you'r buffers.
try using ps -ef or top ( and sort by memory by hitting "m" ) and search for the process that uses you'r memory. -

ThanksThere is as such no fixed value for size each process running on the system is allocated certain amount of vitrual address space in memory for its execution which is based on the algorithm "no of bits in ur processor."
SO the memory usage what u see is perticular to that process in it's given address space in memory which would vary from process to process depending on the tasks the process handles.
These commands give an in depth activity of ur system ,regarding the paging swaping idle process

How can I use unix commands from oracle report
I have to use the following command from oracle reports.
In oracle forms we can use the HOST command but what about oracle reports2.5.
I have to email the attached file 100245.pdf from oracle reports to the given email id
uuencode 100245.pdf 100245.pdf | mailx -s "test" [email protected]Hi,
It's because .bat (or .cmd) files are scripts and not executables and are interpreted using the command line executable - which is normally cmd.exe (although you can buy others).
So you need to call cmd.exe passing the bat file name as a parameter, something like
cmd.exe /c batchfilename
Without the /c you will never get a response.
However, this brings us to the bizarre conclusion that you are going to:
call cmd.exe (a shell interpreter)
to launch a batch file
that calls cygwin (another shell interpreter)
which then runs ls
When shouldn't that just be:
call cmd.exe to run the dir command
Or better yet, If you are just after a file name listing and you seem to understand Java stored procs, why not just write a JSP to list the contents of a directory? No problems with OS dependant commands, scripts and 3rd party interpreters. Plenty of examples of that out on the internet as well.

How can I use custom WLST commands for Oracle SOA Suite in Weblogic
Hi There,
I'm trying to view and search the weblogic log files using WLST on a Solaris/Unix system.
I have come across this "custom WLST commands for Oracle SOA Suite" and thought of using the custom logging commands to get my task done.
However, my WLST shell is not recognizing the commands and giving me the NameError!
wls:/devDomain1/domainRuntime> listLogs()
Traceback (innermost last):
File "<console>", line 1, in ?
NameError: listLogs
I tried the commands listLogs, displayLogs, getLogLevel & setLogLevel but in vain!
I have followed the instructions as per the oracle recommendation of using Custom WLST commands (http://docs.oracle.com/cd/E29597_01/core.1111/e10105/getstart.htm#ASADM10692) as below
- Launched the WLST shell from Oracle Home.
cd ORACLE_HOME/common/bin
./wlst.sh
- Tried to run the listLogs command from domainRuntime()
I would like to know if I need to import any additional libraries to run the custom WLST commands for Oracle SOA Suite in my WLST shell?
I have only weblogic 10.3.1 server installed on my Solaris 10 machine on which I have deployed the OSB application software.
There is no SOA Suite installed.
Or is there any other way I can browse the Server Log file and get the list of log messages? Basically I would like to use this feature in my script to customize it according to my requirement of listing specific error logs which I can work it out if I know how to make these commands work.
Please advise if this is possible and how?
Cheers.
SatishI have tried on my OSB installation (no SOA Suite here), the command listLogs() works (I was in online mode, after a connect), and the classpath is:
