• calculate the CPU used for awhile...

  Hi all
  
  Statpack/AWR report for like 6 hours. How can indicate the % of CPU used for this moment? As we do some planing ability and we need to know how much CPU our instance serve? Thus, when we give the final number of management... .to tell them if 4 CPUS or 8 processors etc etc are good or not... Thank you

  Don't you see a 'CPU time' in the 'Top 5 Timed events' in the AWR report? If this isn't in the Top 5, you would always see in "statistical model time."

  In addition, statistical CPU OS are in 'the operating system statistics '.

• CPU used by oracle user

  Hello
  10 g R2 on Windows SERVER 2003
  user Oracle SCOTT connect to SQLPLUS and runs a large query. Is there some way to see how much CPU he uses?
  
  Thank you.

  CPU used by a user (session wise)
  Select a.sid, a.username, a.osuser, c.name b.value
  session $ v a, v$ sesstat b, v$ statname c
  where = select a.sid
  and b.statistic # c.statistic = #.
  and c.name like '% CPU % '.
  and a.username = 'SCOTT'
  order of a.sid, c.name
  /

  By user (session wise) the following information:
  1 uses of the CPU
  2 kinds of memory
  3. scan of table
  4 validation
  5 slider
  6. physical reads
  7. logical reads
  8 BCHR (buffer hit ratio cache)

  Select a.sid, a.username, a.osuser, c.name b.value
  session $ v a, v$ sesstat b, v$ statname c
  where = select a.sid
  and b.statistic # c.statistic = #.
  and (c.name like '% CPU %') or c.name like ' % sorts (memory) % "or c.name like '% table scan %' or c.name like"% commit %"c.name as 'cursor %' or c.name like ' % read %" or like "% stamp %" c.name c.name like ' % cache %»
  and b.value > 0
  order of a.sid, c.name
  /

  If you have licenses for diagnosis package and the performance pack, you can look at the history of the current session for this type of information. You can query the DBA_HIST_ACTIVE_SESS_HISTORY view, or run the ashrpt.sql script in $ORACLE_HOME/rdbms/admin or use OEM to get a graphical representation of the workload over time.

• High CPU use/Slow Performance after you install the updates of Windows

  I run Vista Business 32-bit.

  After you install many Windows updates in the last few days, I've known very slow performance after the system worked for a while. Resource monitor shows 70-100% CPU usage, even when you run all the apps (that I know of). This makes everyhting grind to a halt, same trip that the mouse jerky movements. I ran several complete system with McAfee anti virus scans and not found problems (using the latest software). The detail showed the so-called ", PID4 NT kernel and system" using 18% avialable CPU capacity, but this process is not always shown to use much more capacity when the slow performance occurs. Nothing else don't use much capacity CPU, I see.

  More recently, the capacity of the CPU became crazy, jumping from zero to 100% usage in a back a suite oscillation. When I shut down and restart, performance improves, but erodes little by little over time.

  Is this a sign of a virus, or is it a problem with the recent Windows updates or some kind of conflict with my software such as McAfee? How do I tell me what to do? Anyone else have this problem with the recent Windows updates?

  Help!  Thank you!!

  McAfee applications (and Norton) are known for not not upgrade (or uninstalling) itself.

  1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

  2. close all open applications (that is, anything with an icon on the taskbar).

  3. now run this triple McAfee fix: http://service.mcafee.com/FAQDocument.aspx?id=TS100507

  NOTE: Step #2 McAfee fix run the removal tool, you have already downloaded in my step #1 above.

  4 IMPORTANT! => After the reinstallation of the McAfee application (step #3 of the McAfee fix), manually & repeatedly updated the McAfee application, until you get a prompt "no update more".

  5. open Internet Explorer (only) to http://support.microsoft.com/kb/923737 & run the difficulty.

  6. OPTIONAL: For good measure, pen also Internet Explore (only) to http://support.microsoft.com/kb/971058 & race that secure it in DEFAULT and modes and AGGRESSIVE. [1]

  7 restart a last time & test.

  ~~~~~~~~~~~~~~~~~~~~~~~~
  [1] full Disclosure: the difficulty operating in AGGRESSIVE mode will remove your update history but not the list of installed updates.

• "Task manager" and Norton AV cpu use 100% constantly, always etc.

  I'm looking at my roommate pc and same problem. under Win XP, SP3.  To run any program takes about 5 full minutes.  CPU use 100% in Norton Anti Virus (NAV) or the Task Manager.  For now I'm just using taskmanger to see the %.  The only way to get to 0-2% is to restart in safe mode.  Go to start/run and msconfig, checked the only button "Load System Services", is went to 'Services' tab, hid Microsoft services and disabled all services, and then restart.  The 100% cpu is always attached to 100%, but the pc certainly significantly faster programs. (almost normal)  Does anyone know how to fix this?  I ran a full NAV of the system scan and a spybot search and destroy scan which finds that some cookies.  Any help would be greatly appreciated.

  Dear Palcouk, I found the problem.

  For someone who has either taskmanager/Norton AV and it shows cpu 100% stable, but when your pc is restarted in safe mode (press F8 repeatedly after reboot), it seems to fall to 0-2%.  Download and run Process Explorer. Once executed with your cpu showing 100%, look under the CPU column.  Regardless of the program see you running the stronger use of the processor is the problem.  You can check this out, as I did by right clicking and "kill process".  Then check your CPU usage again.  Must be 0-2%, which is normal if you are running many programs.  In my case of roommate when I flew over the mouse program svhost using a 99% cpu, it has demonstrated a program that comes from a HP servoce.  It turns out that she has recently reinstalled the drivers of hp printer and somehow it corrupted his PC.  The fix was to reinstall the HP software on write corruption because we were able to uninstall all HP software.  She told me that she was trying to 'fix' the software earlier, but it's probably where corruption has come.  Problem solved.

  Thank you

• VMware ESX server CPU use test alarm

  Hi all

  For a new client, I need to show the alarm and ticket slot functionlity vmware ESX server logging settings

  • Use of the CPU of a server ESX VMW
  • Use of memory for the server ESX VMW

  While I reduced the threshold value of VMW ESX Server CPU use as beloow format

  WARNING - 5% and STDev.warning - 0

  I made this two days before configuration, but still no alarm generated for this rule.

  Help the creation of a test of the abveo metric ESX alarm

  Hi - I ended up having to do such things in the past as well. I just built a virtual machine added lots of processors and memory, then for the CPU, I used the script CPUBusy.vbs from VMware (Google search which) and down it load times so that he began to max real physical processors... For memory, I just opened a massive text file in Wordpad and scroll up and down it. This gave me the circumstances to test the alarms, just don't do as a busy time or use some dev ESX servers...

• on my ap cpu used

  Hi all

  I have a question about the rate of cpu used, my ap has high computer function, as jpeg encode and decode seconds, and when he's throwing for awhile time, the CPU rate used for my ap is superior and superior and then she reach up to 100% result in the user interface is more slower. Is there a solution that could solve this problem? or no matter what concept, I know.

  The issue you describe is not really possible on a BlackBerry.  As a multitasking operating system, it will run quite happily CPU intensive workloads in the background while maintaining good performance of the user interface for the user.

  If your treatment is an impact on the user, it is certainly because you run the processing on the thread of events, you should avoid.

  I think that this article will be useful:

• Password error: your PC is offline. Please sign in with the last password used on this PC.

  I have Windows 8 and you are unable to open a session.  I have reset my password online successfully, but the new password does not work.  The message says: "your computer is offline. Please sign in with the last password used on this computer. "I don't remember last password that I used.   Any ideas?

  Original titile: password is not working on Windows 8

  People it is a very simple and easy solution to this problem! Once you have reset your password from another PC/laptop or any other server for windows 8, you go back to your PC / laptop original where you forgot your password and do the following...

  1. even if you have reset your password, make sure you have an internet connection for this laptop can be wired or WIFI Hotspot even

  2. make sure that connect you using the option under your network settings in the lower left corner of your logg in screen.

  3. Once you are connected then only can type you the new password that you changed.

  NOW, the simple reason for this is that when you have conveniently forgotten your logg in detail on this pc it does not recognize your new password unless it is connected to your online account.

• When I try to access my account, I get the error message "your PC is offline.". Please sign in with the last password used on this computer".

  Hello

  Usually this problem is caused if there any changes in the configuration of the keyboard, or due to Internet connection issues. I would like to know some information about this problem, so that we can help you further.

  1. do you have the question started recently?

  2. have you recently changed the password?

  3. have you made changes on the computer before this problem?

  I suggest you to make sure that the caps lock is not activated, if it is enabled, then turn it off and check if that helps.

  If you are still not able to connect to your account using the password, then I suggest you to check the steps mentioned by Cliff_N on December 7, last here:

• Find a used by a session undo

  Can someone guide me as how can I find the undo tablespace amount used by a session, performed two hours using SQL. The session id is 147.
  
  We use the Oracle 10 g on Linux.
  
  Thank you.

  You mean that how cancel has been built to refresh a quick updatable materialized view? So its very simple, why don't refresh you this MV right now (if the table data is almost the same) and run my query above to see how much it has generated currently. So he has no opinion/way to get the correct information that you ask. Oracle is not undo_generated_history kind of thing.
