Why this anonymus block food full CPU usage (please don't work do not)

Hi all

The code below is to display "Hi" as output after 10 seconds. But why he takes full use of the processor..., in the code I have a keyword OUTPUT, even in this case why it runs in the background?

Please do not WORK the CODE BELOW *.

Set serveroutput on

DECLARE
ten_sec_time VARCHAR2 (4000);
BEGIN
SELECT TO_CHAR ((SYSDATE + 10 / 86400), "hh24:mi:ss of mon-dd-yyyy")
IN ten_sec_time
FROM DUAL;

Dbms_output.put_line ('start... » || SYSTIMESTAMP);

LOOP
OUTPUT WHEN TO_CHAR ((SYSDATE), 'hh24:mi:ss of mon-dd-yyyy') = ten_sec_time;
END LOOP;

Dbms_output.put_line ('end...' |) SYSTIMESTAMP);
Dbms_output.put_line ('Hello');
END;


Kind regards

Billy,
Thanks for the reply, it means that the block will not come out unless we kill the session?

Yes. But it didn't happen if the process was still CPU consumption.

A server Oracle customer service process, is occupied only during execution of the instructions received from the client. When he finished the instructions for running client and the client has not released new instructions of server, this server process is idle.

So either you / your DBA are wrong in thinking that the process server completed, or had completed and was confused with another process server busy completed the process.

  • Satellite A40-231 - 100% CPU usage when any browser works

    Hello
    my laptop is satellite A40-231, I have a problem for days.

    When I open any browser (I tried firefox, IE and chrome) I can't watch the video, everything is slowing down, I can't navigate between pages.

    I took a quick glance to the use of the cpu and it increase to 100%, it never decreases. When I close the browser, the CPU usage drops to 15%, which is normal. I thought it might be a virus that internet connection and make things slower. That's why I format my laptop. I deleted all of my hard drive and reformatted. I installed Windows again, but he has not changed. I even installed ubuntu (I thought maybe virus can not work under ubuntu), but it's the same thing. I turn on my laptop and I open a browser and the laptop slows. I have clean the cpu fan it has not helped.

    I tried to solve it for days I could not sleep properly, I'm about to cry :(

    Please help me please.

    Hello

    You have reinstalled Windows using the Toshiba Recovery disk? This drive will restore the settings from the factory with all the drivers and tools so everything should work fine after that.

    In addition this happens with LAN or WLAN connection? You should try it with the other connection.
    Also check your router and update the firmware. Try to disable the encryption, MAC address filtering, etc.

  • Why Firefox for android uses 26% CPU on my laptop when I'm not with her?

    When I left Firefox were not yet all slow - pages (about: Home)

    This will lead to draining the battery unnecessarily.

    So why use Firefox so many cycles CPU for everything: home, if you're running javascript on a page that I closed? (wired.com)

    Could you provide the latest version of Firefox that is running on your device as well as the type of device you have (brand, model, and version of Android).

  • Under Win 10 Pro, updated to v40.0; "Minimize full screen & Exit" buttons don't work. Re - download and re - install did not set; decommissioning of v39.0.3 fixed?

    Windows Pro 10. Update Firefox to v40.0. At the top, buttons full screen and the exit on the right, minimize it, didn't work and hovering on any of them could not highlight the button. I have re-downloaded the update and re-installed, but the problem still exists. As a test, I tried downgraded to v39.0.3, which fixed the problem. I realize that the downgrade may pose a security risk, but it works, and not v40.0! Prior to decommissioning, I tried the customization option, out, re - click on the menu bar, but neither helped. What to do next?

    BOBHAKES said

    In addition to troubleshooting: I opened v40.0 Firefox in safe mode, and the problem occurred is no longer. Then restarted, open Firefox v40.0, using the option "Refresh", and the problem occurred is no longer. After add desired Plug-Ins and Extensions (eliminating some older or infrequently used items), I restarted Firefox, and the problem no longer occurs. Obviously, the problem was caused by one of the extensions eliminated or plug-ins. No other assistance needed.

  • Excessively the CPU usage high on my Equium M70

    Hello

    Recently in the last month my summer CPU usage hit 100% when I m not running any software tax (only internet explore and windows media player).

    It is slowing down the load time and the area near the fan is hot enough.

    I have a Satellite M70-337, with a 1.7 centrino processor and now 2 GB of RAM (formerly 512 megabytes). I upgraded the ram in December and had no problems like that, now it just started happening recently, I have installed everything that would, there is no unnecessary programs running and it was after I restored my computer to factory with the startup disk settings (a month later), he seems to have come from nowhere. On the list of the Task Manager it shows my web browser and Media Player by using most of the CPU, but I could have sworn that they use so far before.

    I don't know if the RAM would have been a factor, but it was the correct RAM for it and windows recognized to 2 GB.

    Why would it suddenly happened any ideas guys?

    Hello

    I have the same model of laptop and at the moment I have no such problems. To be honest, I did new installation OS 3 months ago and after installing Microsoft Update, I noticed this laptop does not work as before. Just for example: if I use IE7 extensively with several different tabs in the Task Manager I can see this need for IE more than 300,000 k of memory and crashes somehow. After the closure of the IE and ending THE process sin Task Manager I can work normally again.

    I don't really know how your operating system is configured, but in the Task Manager, you should see what running process is responsible for the high CPU usage. Maybe some antivir application? Sorry, but it is really not easy to sayt why this happens. Play around with the current process.

  • Why did FireFox flash black and then cause a huge CPU usage and crash?

    I don't know if this has been asked before, but on Windows 7, FireFox will cause a high CPU usage and the black flash and then crash. No idea why? Acceleration is disabled for the options and flash.

    Would help if we could read your Crash reports.

    Please follow the steps below to provide us with crash IDs to help us learn more about your accident.

    1. Enter Subject: hangs in the Firefox address bar and press ENTER. A list of submitted Crash reports will appear, similar to the one shown below.
    2. Copy the 5 most recent report ID that begins with a bp - then go back to your forum question and paste the ID into the box of "Post a reply".

    Note: If a recent report ID does not begin with bp - click it to present the report.

    (Please do not take a screenshot of your plant, just copy and paste the ID.) The image below is just an example of what your Firefox screen should look like).

  • Why my always 100% CPU usage and what is RegSvcs.exe uses 50% of it?

    Hi people,

    I think I need urgent help though.

    Recently, I thought I downloaded malware that is injected with the Trojan horse. And now, I believe that the Trojan horse lies in my computer. I did this because my CPU usage is always at 100% even when I just restarted my com. Initially, I found there was a program called dgen.exe running in my computer to a 60% of CPU usage. Never so, I remove the dgen.exe from my computer but I don't know if I remove it entirely. Now, I'll have another program called RegSvcs.exe in my computer operating at 50 percent CPU usage. I googled out and it says it may or may not be required by windows and it could be a trojan virus as well. That's why there at - it anyone who can enlighten me on this?

    I have to delete or to update or something?

    Thank you.

    Kind regards.

    By far, this is related to the Malwarebytes with steam being far behind.  Your Cpu & your HD and combination of slow down the computer.

    I would remove MBAM at least to test

    This problem sometimes occurs when my computer starts. Today, it happened and actually picked up my internet connection, which also won the update of Flash Player and Internet Explorer open. Also, I couldn't get the Start Menu to open. What is happening to the CPU is too busy doing something else? Is there a way to refresh the process or the CPU?

    Hi Hope_H,

    1. did you of recent changes on the computer?

    2 when was the last time it was working fine?

    3. do you have security software installed on the computer?

    4. you receive an error message?

    Checking service or program uses high processor usage by using Task Manager.

    To view the CPU usage, press CTRL + ALT + DELETE, click Task Manager, and then click the performance tab.

    Overview of the Task Manager

    http://www.Microsoft.com/resources/documentation/Windows/XP/all/proddocs/en-us/taskman_whats_there_w.mspx?mfr=true

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you put the computer in a clean boot state and check if it helps.

    To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.
