Querying application for high cpu usage
Hi , I need to run / create a report that could query a application that using alot of cpu resources, but the thing is that it would need to check every service or task that is run by the application?
Thanks
Hi,
As we can see, the lsit of application in the task manager sorted by CPU usage always change. And with SCOM, we can only get out performance report for monitored objects, but cannot get the application name which eat most CPU.
It is suggested to create performance monitor to set alert when avaliable CPU is below a value, so that we can check the task manager on the agent monitored which cost most CPU.

XML select query causing very high CPU usage.
Hi All,
In our Oracle 10.2.0.4 Two node RAC we are facing very high CPU usage....and all of the top CPU consuming processes are executing this below sql...also these statements are waiting for some gc wiat events as shown below.
SELECT B.PACKET_ID FROM CM_PACKET_ALT_KEY B, CM_ALT_KEY_TYPE C, TABLE(XMLSEQUENCE ( EXTRACT (:B1 , '/AlternateKeys/AlternateKey') )) T
WHERE B.ALT_KEY_TYPE_ID = C.ALT_KEY_TYPE_ID AND C.ALT_KEY_TYPE_NAME = EXTRACTVALUE (VALUE (T), '/AlternateKey/@keyType')
AND B.ALT_KEY_VALUE = EXTRACTVALUE (VALUE (T), '/AlternateKey')
AND NVL (B.CHILD_BROKER_CODE, '6209870F57C254D6E04400306E4A78B0') =

Also not able to generate execution plan for this sql using explain plan- getting error(ORA-00932: inconsistent datatypes: expected - got -)
Please help me in this issue...
How can i generate execution plan?
Does this type of XML based query will cause high GC wiat events and buffer busy wait events?
How can i tune this query?
How can i find that this is the only query causing High CPU usage?

I think xml schema is created already...and its progressing as you stated above. Please correct if i am wrong.
I found all these sql from AWR report and all of these are very high resource consuming queries.
And i am really sorry if i am irritating you by asking all stupid questions related to xml.

Excessively High CPU usage on my Equium M70
HI,
Recently in the last month my CPU usage as been hitting 100% when Im not running any taxing software (just internet explorer and windows media player).
This is slowing down loading times and the area near the fan is pretty hot.
I have an Equium M70-337, with a 1.7 centrino processor, and now 2 gigs of RAM (formerly 512 megabytes). I upgraded the ram in December and had no problem like this, now it's just started happening recently, I haven't installed anything that would do it, there are no unnecessary programs running and this was after I restored my comp to factory settings with the startup disc (about a month after) so it seems to have come from nowhere. On the task manager list it shows my web browser and media player using up the majority of CPU but I could have sworn that they didn't use up this much before.
I don't know if the RAM would have been a factor but it was the correct ram for it and windows acknowledged to 2 gigs.
Why would this have happened suddenly, any ideas guys?Hi
I have the same notebook model and at the moment I do not have such problems. To be honest I have made clean OS installation 3 months ago and after Microsoft update installation I have noticed that notebook does not run like before. Just for example: if I use IE7 intensively with several different tabs in task manager I can see that IE need over 300.000 k of memory and somehow blocks. After closing IE and ending the IE process sin task manager I can work normally again.
I really do not know how is your OS configured but in task manager you should see which running process is responsible for high CPU usage. Maybe some antivir application? Sorry but on this way it is really not easy to sayt why this happen. Play little bit with running processes. -

Spooster IT Services.Hi Gurjar,
r u getting the below mentioned syslog messages?
Flow is denied by configured rule (acl-drop) 103915
106023, 106100, 106004
TCP Out-of-Order packet buffer full (tcp-buffer-full) 1949
TCP Out-of-Order packet buffer full:
This counter is incremented and the packet is dropped when appliance receives an
out-of-order TCP packet on a connection and there is no buffer space to store this packet.
Typically TCP packets are put into order on connections that are inspected by the
appliance or when packets are sent to SSM for inspection. There is a default queue size
and when packets in excess of this default queue size are received they will be dropped.
Recommendations:
On ASA platforms the queue size could be increased using queue-limit configuration
under tcp-map.
Similarly you need to check many reasons for the asp drop logs that you have captured and you need to monitor how much it is increasing and the difference.......
but 40 % CPU utilization is a okay kind of thing and you do not need to worry if that happens only during peak hours ans it is not increasing drastically more and more.

Windows 8; high cpu usage on explorer (~50%)
I just restore my laptop, and now i noticed that my usage is above 50% and the major usage is because of explorer.exe which showed 49-53% in Task Manager.
Is that normal? Is there any solution to lower down the usage for explorer?Hi,
For high cpu usage issue, I usually use Process Explorer to troubleshoot, here is a link for you to download:
Process Explorer v15.40
http://technet.microsoft.com/en-in/sysinternals/bb896653.aspx
It's a simple and small tool, once you installed and open it, locate to explorer.exe, you will find all processes related with explorer running in your system, find the culprit of the high cpu usage.

High CPU Usage On client application when upgrade remote SQL database
Hi,
Is anyone here encountered very high CPU usage after upgraded the database from SQL 2005 to SQL 2012? Following describes my issue.
I have my client application running on Windows 7 that access to central database (SQL 2005) on Windows server 2003 using ODBC connection, this client application basically query data and perform data insert and update. There are a number of this similar
clients connected to the database.
Due to slowness of the database server, company decided to upgrade the database server to SQL 2012 and also new hardware runing Windows Server 2012. There is no change on the client application and client hardware and the client application still using the
same ODBC connection to query, insert or update the new database server.
The problem I am now experiencing now is that my client PC where my client application running the CPU usage is very high almost hitting 100% when accessing to the central database. I am also noticed this program lsass.exe that utilized almost 40-50% of
the CPU time when client application accessing the central database.
Is anyone here know, why client PC CPU usage 100% when access to upgraded SQL 2012 database? What is lsass.exe program doing, it only appear when accessing to database server. How to reduce the CPU usage on client?
Thanks.
Chee Wee.Hello,
After upgrading, please rebuild indexes and update statistics on the databases.

High CPU usage (more than 100%) while running video applications
Hello everyone,
I desperately need help with this.
I have a late 2007 White Macbook running Mac OS X 10.6.8 :
Model Name: MacBook
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 3 GB
Bus Speed: 667 MHz
The issue that I am having is, whenever I play a video (Netflix/Silverlight player, YouTube, Skype, etc.) the CPU usage shoots up above 100% and the video or the video chat becomes VERY choppy. It becomes impossible to keep going once that starts. Originally I had 1Gb RAM (512 + 512) ... then I upgraded to (1GB + 512mb) ... it was fine for about a year and then started chocking on memory... so recently I made it (1GB +2GB) and that's when this high CPU usage thing started (according to my knowledge)
I have had this machine since last 4 years and its very dear to me. I dont wanna buy a new one. I will really appreciate if someone could help.I am spending sleepless nights, researching for a fix. From what I found so far, a considerable amount of people were able to fix this issue by simple cleaning the insides of their machines using air dusters, especially the fans. I don't know how cleaning would help with CPU utilization, but by interpolation, I feel it's worth a try. At least it will be clean, if not perfectly functional. lol
Now the next big challenge ahead of me is getting the screws on my Macbook open. I was following the Fan Repair Guide on ifixit.com. I went and got the #00 Phillips screwdriver as suggested in the guide... came home and found out the screwdriver is too big.... went back got a #0000 Phillips (I also found out that screwdrivers with same number might be of different sizes in different stores)... got a couple of screws out and then--- another road-block!! there are a few extremely tiny Phillips screws on my macbook. Now I am hunting for the smallest Phillips screwdriver in the world. Hopefully, I will find it in some watch repair or eye-glasses repair kit in a store such as CVS or Walgreens... aaaah... this is sooo frustrating!!! I just want to get his done so that I can check it off the list of probable solutions that I want to try. Will update here if this works.
From what you say, I think that the Silverlight upgrade might be the culprit in my case too. But the effect is there also for Youtube, Skype , or any other Video/Graphics intensive application that I use. Although, Silverlight/Netflix performs the worst among all the apps.
I love my Macbook... don't want to part with it. -
High CPU usage, Live Ultra for Notebooks
I've been using the Live Ultra for Notebooks for a while, and it has consistently high CPU usage. It breaks down to about 50-60% for the driver (V0070Vid.sys thread, in the "System" process) and then a bit more (+5%) for DPC's. Combined with the host application (Skype, 25% CPU) means the whole thing essentially takes over my CPU.
Is this typical CPU usage for this webcam? I've used other ones, and I seem to remember that CPU usage was a lot lower. I have this problem on 2 different computers.
AMD Sempron 300+
GB Ram
Windows 2000 SP4
Please post what webcam, CPU, OS, and about how much CPU % your webcam takes. I'd like to see if these results are normal. Thanks.I also have a Toshiba laptop with Vista Home Basic. I tried to install the "BETA" Vista drivers for this camera (VF0070) and it says the driver is only for Vista 32-bit and 64-bit. Is there a solution to this? Should I just return this and go buy a Logitech instead?

High cpu usage when moving application windows
Hello all,
I have two machines with arch installed:
- an eeepc 701 surf/intel gpu(xorg driver) with xfce
- an amd 3800+ X2/nvidia 8860 gt(proprietary driver) with kdemod3(also checked with xfce4)/arch amd64 installed.
I noticed that when i move a window of an application(for example konsole, etc..) too fast i get high cpu usage(30-40 %), when checking with htop.
Is it normal that the X server uses the cpu so much when moving a window??
EDIT: up to now i tested it in a friends windows machine, and it happens exactly the same, so i guess is normal. It seems i need to be informed better about how X works :-)
Last edited by mechmg93 (2008-10-15 08:04:10)today i switced back my desktop system to debian unstable and tried to see what the difference is concerning this problem.
I found out that in kde3 the solution to the "problem" is debians kde default configuration about window behaviour.
Especially the one mentioned below :
In debian this is not ticked and this has as a result zero cpu usage when windows are moved.

We have a table named "tbl_geodata" which has address and latitude and longitude values. We
also have a "History" table which has only latitude and longitude values including other information. What we need is like following...
We get a set of records based on a query from "History" (lat long values), say 5000 records
Now we are using the following formula to calculate address from the "tbl_geodata" for each row
(5000 rows).
SELECT top 1 geo_street,geo_town,geo_country,( 3959 acos( cos( radians(History.lat) ) cos( radians(
gps_latitude ) ) cos( radians( gps_longitude ) - radians(History.long) ) + sin( radians(History.lat) ) sin( radians( gps_latitude ) ) ) ) AS distance FROM tbl_geodata ORDER BY distance
Currently we are seeing high cpu utilisation and performance issue. What would be the optimized way to do
thisWe are using SQL Server Web Edition. We have a table which has around 120 million records (every second around 100 insertion). It has a AFTER INSERT trigger to update another table. There is following performance issue we are facing.
High CPU Usage
Insertion failed (Connection Timeout Expired. The timeout period elapsed during the post-login phase. The connection could have timed out while waiting for server to complete the login process and respond; Or it could have timed out while attempting

One of the web application is sudendly consumming high cpu usage.
hi
there are two web application running on the the standlone server.one of the web application is sudendly consumming high cpu usage. because of this issue, the entire cpu usages become very high and result in HTTP THROTTLING error. please suggest ways to
resolve this problem.
in the same standlone server, what are the service that must not run or minimum services that are required.
server:-
48 gb ram,
8 core processor
thanks in advancedHi jackhill,
Please check whether you configure Search service in your SharePoint.
And please use Taskmgr on the server to check which process may be cause this issue.
In addition, there is an article about high CPU in SharePoint 2013, please check if it is useful for you:

High cpu usage for garbage collection (uptime vs total gc time)
Hi Team,
We have a very high cpu usage issue in the production.
When we restart the server, the cpu idle time would be around 95% and it comes down as days goes by. Today idle cpu is 30% and it is just 6th day after the server restart.
Environemnt details:
Jrockit version:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
BEA WebLogic JRockit(TM) 1.4.2_05 JVM R24.4.0-1 (build ari-38120-20041118-1131-linux-ia32, Native Threads, GC strategy: parallel)
Gc Algorithm: JRockit Garbage Collection System currently running strategy: Single generational, parallel mark, parallel sweep
Number Of Processors: 4
Max Heap Size: 1073741824
Total Garbage Collection Time: 21:43:56.5
Uptime: 114:33:4.1
Total Garbage Collection Count: 420872
Total Number Of Threads: 198
Number Of Daemon Threads: 191
Can you guys please tell me what would be problem in the server which causing the high cpu usage?
One more thing I would like to know is that why the total number of threads is 198 when we specified the Executor pool size as 25? I agree that weblogic would create some threads for its maintenance but around 160 threads!!! something is wrong I guess.
Santhosh.
[email protected]Hi,
I'm having a similar problem, but haven't been able to resolve it yet. Troubleshooting is made even harder by the fact that this is only happening on our production server, and I've been unable to reproduce it in the lab.
I'll post whatever findings I have and hopefully we'll be able to find a solution with the help of BEA engineers.
In my case, I have a stand-alone Tomcat server that runs fine for about 1-2 days, and then the JVM suddenly starts using more CPU, and as a result, the server load shoots up (normal CPU utilization is ~5% but eventually goes up to ~95%; load goes from 0.1 to 4+).
What I have found so far is that this corresponds to increased GC activity.
Let me list my environment specs before I proceed, though:
CPU: Dual Xeon 3.06GHz
RAM: 2GB
OS: RHEL4.4 (2.6.9-42.0.2.ELsmp)
JVM build 1.5.0_03-b07 (BEA JRockit(R) (build dra-45238-20050523-2008-linux-ia32, R25.2.0-28))
Tomcat version 5.5.12
JAVA_OPTS="-Xms768m -Xmx768m -XXtlasize16k -XXlargeobjectlimit16k -Xverbose:memory,cpuinfo -Xverboselog:/var/log/tomcat5/jvm.log -Xverbosetimestamp"
Here are excerpts from my verbose log (I'm getting some HT warning, not sure if that's a problem):

So, I'm running with the default GC strategy which lets the GC pick the most suitable approach (single space or generational). It seems to switch to generational almost immediately and runs well - most GC runs are in the nursery, and only once in a while it goes through the older space.
Now, if you look at [Sun Oct 22 02:50:27 2006], that's when everything changes. GC starts running every second (later on it's running 3 times a second) doing huge sweeps. It never goes through the nursery again, although the strategy is still generational.
It's all downhill from this point on, and it's a matter of hours (maybe a day) before we restart the server.
I guess my only question is: What would cause such GC behavior?
I would appreciate your ideas/comments!
Thanks,

High CPU usage for SERVER0 process in XI
Hi,
SERVER0 process is taking high CPU usage, previously it happen once its due to communication channel error, So we deativated some unwanted communication channels in Alert config and the CPU usage is reduced.
After some weeks its again CPU usage is increasing for SERVER0 process in some time.
Can anyone help in this case.
Thank you,
gopi.Hi Gopi,
Check out Tim's reply and check for ur Java stack settings,
Extended Memory parameters
<i>The bottom line for J stacks is to keep everything in memory and out of swap. </i>
Other tips:
- u may try clearing folder usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\apps
- try increasing virtual memory
- increase heap size

Safari 3.03 for Mac has high CPU usage usually above 70%
I look at the Activity Monitor and it shows Safari using a lot of CPU % around 70 % and some times near 100%
This High CPU usage is also a problem that has just started recently on my G4/667/1.5Gig Ram with a "Giga" 1.33GHz upgrade running System 10.4.10. My machine has been wonderful for years with this processor. I'm running Safari 2.0.4. When i did the last upgrades to my software I started having some real bad behavior from my mac. High CPU usage in safari (80-98%) for 3-5 minutes then normal like now I'm at 6-10% (Normal)as I type this in Safari. Safari is crashing when I try to open the Apple in store training site! Mail was crashing on my wife's login not mine though. Throwing out her mail Prefs fixed that. The Upgrades that seem to trigger this are Java for Mac OS 10.4 Release 6, Quick Time 7.3.1, GarageBand 4.1.1, iPhoto Update, iTunes 7.5. It sure feels like that last set of upgrades has made a mess of my mac. I suspect the Java update. How do I fix this mess???? [email protected]
