User consumes more CPU

Hai all,
Suddenly the output of top command shows that f60webmx consumes 100% of the CPU. like :

How to find the sessions/user consuming more temp tablespace

Environment details
IBM-AIX 64 bit
Oracle 10.2.0.4.0
Recently we encountered the issue of sudden peak in CPU utilization and temp tablespace usage. We are noticing this issue after Apr CPU 2009 patch and upgrade to 10.2.0.4.
Recently temp space was full and we added 18 GB of space to temp tablespace, within few hours, they are also consumed.
Application team is telling that they did not modify any code. ADDM report suggests most of the recommendations related to SQL tuning only
not sure about the real issue. Can somebody tell me how I can find what are all sessions/user consuming high temp tablespace
Edited by: user1368801 on Sep 1, 2009 5:32 PM

Hi,
Run below query to check if it is used by any session.
select sum(a.BYTES_USED)/1024/1024 used_mb, sum(b.bytes)/1024/1024 total_mb,
sum(a.BYTES_USED)/sum(b.bytes)*100 pct_used
from V$TEMP_EXTENT_POOL a, v$tempfile b
where a.file_id(+) = b.file#
Check who is using it by the below query.
SELECT s.sid,s.serial#,osuser,process,program,s.sql_hash_value,u.extents, u.blocks
FROM v\$session s, v\$sort_usage u
WHERE s.saddr = u.session_addr order by extents,blocks desc
Hope this solves your issue.

Unknown user occupy more USER I/O

Hello friends, Our environement is ORACLE 10g ON WINDOWS 2003 platform. We use to receive call from some users that system is very slow in response. While I check through OEM , one user consuming more USER I/O, 90%. But that users for IT department user and I confirmed no one working with that user account. I dont know how this user session is automatically created and consuming more I/O. I stop all the scheduled jobs that used that user name. Its regarded less of the time, some time morning , some time night
this user sesseion created autmatically. I killed those sessions, even than its creating some other session with the same user name and occupying more I/O. Kindly help me to solve.

Hi,
We use to receive call from some users that system is very slow in responseDo these users shared same applicaiton? Means, is whole database slow (all users are suffering) or only a few users suffering while running same applicaiton?
one user consuming more USER I/O, 90%This is this user's part in total IO on the system which not necessarily means that IO is slow.
Course of Action
Through OEM check the system performance page, what is CPU in IO wait matrix value.
Through OEM, also check Disk busy rate for the disk where your database is residing
What are the details of user sessions which is consuming 90% IO. Username, session from which machine, from which program etc.
OEM performance page will also show you what SQL it is running. If no one owns this user, just lock it and check who shouts.

You don't run statspack for 24 hours, that would infact be pointless...
Run statspack for say a 10 or 15 minute window during a particular "busy" period on your database. If you run it for longer then all the useful data will have been "averaged out". You want a snapshot in time, not an average over the day.

Dbwr consuming high CPU after enabling DirectIO

Hi,
DBWR is consuming high CPU. After enabling DirectIO on Solaris SPARC 10, dbwr is eating away almost 1 CPU on a v440 machine i.e. 19% throughout the day. Neither of "buffer busy waits" or "write complete waits" or "free buffer waits" are in the top 5 wait events, which, to me, means that there is no buffer contention.
What I understand is that after enabling DirectIO, it takes longer for the IO to complete because pre-DirectIO it would return from the file system cache whereas now it has to return from the disk (and I do see at the OS level that IO has become slow), but should that result in dbwr consuming more CPU?
Infact after enabling DirectIO, IO has become very slow which is another problem and as a result log file writes have also become slow which is a 3rd problem. btw, I am aware that if there were many FTS, then DirectIO can make the system slow but there are no FTS in my case. Also, that SGA should be increased after enabling DirectIO, which has also been done.
Thanks

Yes, removing the file system cache from the I/O layer for a device can reduce I/O performance if the caller does not perform its own caching. However, direct I/O will eliminate the system cache overheads (and associated CPU resources needed) from a caller (like Oracle) that implements its own sophisticated buffer cache.
Direct I/O should therefore increase Oracle I/O performance and decrease resource footprint as it eliminates the need for the kernel to maintain a cache for that device.
Infact after enabling DirectIO, IO has become very slow which is another problem and as a result log file writes have also become slow which is a 3rd problem. Direct I/O, as per the Sun docs, is an advisory call. It may not place that device in direct I/O modes. It may result in partial direct I/O. So you need to make sure exactly what happens and how successful (partial or complete) this setting was.
btw, I am aware that if there were many FTS, then DirectIO can make the system slow but there are no FTS in my case. FTS (multi block reads/large sequential reads) is slower? This is contrary to Sun's docs that state:
Large sequential I/O generally performs best with DIRECTIO_ON, except when a file is sparse or is being extended and is opened with O_SYNC or O_DSYNC.

OVI suite consumes more than 50% of my CPU and doe...

I just installed the most recent version of the Nokia OVI suite. Although it doesn't even recognize my Nokia phone (connected via USB and in PC suite mode) the software consumes more then 50% of my CPU resources. Most resources are used by the NokiaMServer.exe, even if I don't start the software.
My system is in an unuseable state with the OVI suite. What's wrong with this tool?
Im using Windows 7, 64 Bit and my system is stable. Or should I say: Was stable befor i installed the OVI suite?

Yes... i used the maps on my device. But i don't like them because they aren't too detailed for my country. So i thought i should check for some updates. I installed ovi suite. By the way the .exe from the phone card didn't worked so i downloaded the latest version from the official nokia website. The suite told me i have some additional featureas for my maps so i started updating them hoping things will be better after i do so. I can't give any review yet of the new maps, because i'm still installing them.
The firmware version of my phone is the last one: 033.002
Anyway this isn't the problem we are discussing here. We are discussing the fact that the software runs very poor on normal computers. I have an E8400 3.0 Ghz proc, 4 GB ram.
By poorly i mean it takes ages to do something. Only the start up of the programme took 1 minute. They should definetly make some changes in the software. But i guess nobody from nokia ever reads this forum.

Exchange 2013 - The Microsoft Exchange Transport service is rejecting message submissions because the service continues to consume more memory than the configured threshold

Noticed at about noon that no emails had been received all day. Began to investigate and found that the MS Exchange Transport service had been set to deny email submission because it was using too much memory on the server (91%).
The error message makes me think that we may have been getting used by malware or something similar.“The Microsoft Exchange Transport service is rejecting message submissions because the service continues to consume more memory than the
configured threshold.”
There are also several warning messages that list particular IP addresses and say that a connection from that IP was denied because there were already the maximum number of connections (20).
From what I can tell, all of the IP addresses are from Taiwan.
The time period for which some emails may be missing is from close of business yesterday ( 4/3/2014) through about 12:45 today (4/4/2014).
From the time I spent reading and trying to figure out the error, I think we may need to readjust our throttling policies to prevent this from happening.
The exchange server is currently running at 90%+ CPU and 50%+ memory usage the majority of the time, and I’m not sure how to fix it.
Also, I cannot get into EMS I get a access denied message from the destination computer. (Exchange server) I want to get into there to change the throttling policy back to default, since we disabled it.
The Error reads:
The WinRM client cannot process the request. The WinRM client tried to use Kerberos authentication mechanism, but the destination computer <Exchange> returned an 'access denied' error. Change the configuration to allow Kerberos authentication
mechanism to be used or specify one of the authentication mechanism supported by the server. (How do I do this?) To use Kerberos, specify the local computer name as the remote destination. (I'm trying to use EMS while logged into the local Exchange server)
Also verify that the client computer and the destination computer are joined to a domain. (Exchange is on our domain, and the computer trying to connect is the same computer) To use basic, specify the local computer name as the remote destination, specify
Basic authentication and provide user mane and password. Possible authentication mechanisms reported by server.
At line:1 char:1
+ New-PSSession -ConnectionURI "$connectionUri" -ConfigurationName Microsoft.Excha ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [New-PSSession], PSRemotingTransportException + FullyQualifiedErrorId : AccessDenied,PSSessionOpenFailed
I assumed control of this exchange system already in place and I do not have much experience with exchange 2013 or server 2012. I do know 2008, but that doesn't help very much in this situation.
Recent changes to the system:
About three days ago we switch our sessions policy to allow many more connections, and I believe this caused the issue. This is what I changed it to:
Made the registry DWORD (32-bit) "Maximum Allowed Sessions Per User" and modified the value to 1000. Location of registry change @ HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
I just changed it to 10 from the 1000. I'm hoping this solves this. So far no.
Also, I am not the best in the shell or command line interfaces. Any help would be wonderful!

Hi,
Yes, could be hardware performance issue. Try recycle the Transport process and see if the issue persists.
Thanks,

Safari consuming 80% + CPU

On our PowerBook G4 - we've noticed that Safari seems to be consuming more and more CPU lately. Restarting Safari if it's been running for more than a few days, or even rebooting the PowerBook helped in the past when we had this issue, but not anymore. Even from a fresh reboot, with no other applications running, launching Safari (which opens Apple's welcome page) consumes 90% or more CPU.
I've tried the following:
- removed the ~/Library/Caches/Safari folder
- removed the ~/Library/Safari/Icons folder
- removed the comp.apple.Safari.plist file from ~/Library/Preferences folder
- resetting Safari
No effect. This machine is still running Safari 2.0.4.
It's interesting to note that if I switch to another user, their CPU usage is fine when running Safari... which makes it an issue in the User folder, instead of a further system corruption or issue. But I'm at a loss for what else to do to the "affected" user's folder to clean this up. Running FireFox is fine.
I thought maybe it was the Internet-Plugins, so I moved them to the desktop and launched Safari, same issue...
Any ideas?
Thanks in advance,
Sean

I have found the issue...
After trying a fresh install on an external drive and migrating the user accounts - the issue was still there, meaning it was definitely a User account issue.
I created a user called "test" and copied the folders from the affected User's Library folder one by one, restarting Safari each time to check CPU usage. Once I copied over the "Syndication" folder and started Safari, the issue was reproduced.
Returning to my affected user account, I moved this folder to t he desktop - fired up Safari and after a brief blip of CPU usage the CPU usage settled right down and stays there. A new "Syndication" folder was created in it's place and now Safari behaves.
In the Syndication folder that I moved, the following were the contents:
- Damaged Database
- Damaged Database #2
- Database3
- DotMacSyncCache
I had seen these before and assumed (wrongly) that the creation of a new file might mean that the damaged ones were no longer in the picture. The new folder created 1 file so far, called "Database 3", apparently it knows some history from somewhere.
I think I can delete these, but I'll do some research on that before I do, but thought I'd update this in case my findings help someone else. If you know more details on what these do - feel free to update this thread further.
Thanks everyone for your suggestions. This was a new one for me for sure.

I you have any clue what might be going, I would be very happy to hear it. It's really annoying, as I have to kill explorer.exe and thereby close all my folder windows when this happens.
Thank you!
Best regards,
David Trapp

Hello,
thanks for having a look. However, I already ran SFC before posting on this forum (as part of my own investigation) and it came back clean. RescueTime (a time tracking tool) is probably not the culprit because it happened also several times in the past without
RescueTime being running (that was because I had accidentally removed it from autorun at that time).
Unfortunately, I can't follow your "invalid date" explanation. I don't think an "invalid date" is anywhere involved; in fact, the method in question is called "_TreeInvalidateItemInfo" and not "_TreeInvalidDateItemInfo"
(note that there is only one "d"), so I assume its job is just to invalidate (and in turn, refresh) the cached information about nodes in the left pane's folder tree of the explorer window(s) - since the folder tree is the only NamespaceTreeControl
(whose corresponding class name is CNscTree) in explorer folder view windows. As I see it, something is causing explorer to repeatedly refresh the folder tree data, but I am stuck at finding out what exactly.
Best regards,
David Trapp
EDIT: Disassembling ExplorerFrame!CNscTree::_TreeInvalidateItemInfo confirms that, because it seems to call TreeView_SetItem for a tree node and its parent (possibly with all fields set to *_CALLBACK), and CNscTree::_UpdateItemDisplayInfo
for the parent node.
EDIT2: I'd love to dig more into the trace, however I am hitting a wall at function names/addresses. Everywhere where I would expect a function name/address (such as the "by stack" views), I only see question marks instead. What
could be the reason?

"IMAQ Stop" takes 10sec to execute and consumes 100% CPU

Hi, I'm calling IMAQ Stop to end an acquisition but it consumes 100% of my processor and takes 10sec to complete (all the while consuming 100% CPU). In our application we start and stop the camera regularly and this is exactly when the user wants the program to be interactive so this 10sec delay is a big irritation to them.
My setup is - Dalsa Piranha line scan camera, RT 9 running on a desktop PC (it is compatible according to the test), PCI-1429 cameralink card.
Any help or comments welcome.
Thanks.
Solved!
Go to Solution.

Ah I have managed to solve this one, but first here are the answers to your questions:
Using Stop and then Close or just Close makes no difference. The Stop was taking so long that I simply used a probe before and after it on the error cluster and with 2009's probe timestamp function I could easily see how long it took. For more detailed timing analysis I use the us timer available with RT.
In any case, the way I solved the problem was by making sure that I stop the acquisition BEFORE the line clock to the camera is stopped. So IMAQ Stop probably waits for the end of the current frame before it returns - and if the line clock stops halfway through a frame (as was the case), a 10 sec timeout probably causes Stop to return eventually.
The line clock is being driven by a DAQ card (via RTSI) and I simply closed the session to that counter AFTER calling IMAQ Stop. The DAQ interface is not shown in the example above as it is coded in a different vi.
Thanks for all the help.
