Data Base 11G is consuming all cpu

i have installed a oracle database 11g and Apex in a vitual machine, I start the virtual machine and also database services start, but after three minuts the consume of CPU for oracle.exe process it grow much until cosume the 100% of CPU
i don´t know what happen, wich is the cause?

  • Ifconfig hangs consuming all cpu

    I just ungraded my 2005-6ish 13" mac book to snow leopard and I noticed that when I was connected to wifi my CPU was pegged at 100% despite not doing anything. Checking the activity monitor showed two instances of ifconfig consuming all my CPU, and they just kept running and running.
    I tried force quitting them and new ones popped back in their place. Starting up a terminal I checked for running ifconfigs:
    [12:03:57 ~]$ ps -aex | grep ifconfig
    8310   ??  S      0:00.00 /bin/sh -c ifconfig -a | grep inet
    8311   ??  R      1:40.05 ifconfig -a
    8317   ??  S      0:00.00 sh -c ifconfig en1 | awk '{ if(match($1,/ether/)) print $2; }'
    8318   ??  R      1:18.01 ifconfig en1
    And if I run ifconfig directly, it just hangs never completing:
    [12:03:14 ~]$ /sbin/ifconfig.old

    I thought it might be something related to my account, but it also happens if I log into the guest account. This happens on multiple wifi networks and after a clean boot. Software update says I'm completely up to date. Any help would be greatly appreciated.

    I'm not sure why this solution works. I didn't dig very deep after I used it to fix the problem on my Powerbook G4. However, if you're interested there is a discussion here:
    http://smartic.us/2007/11/8/leopard-100-cpu-usage-caused-by-syslogd-and-possibly -time-machine
    There is also a short article in the "TipBITS" column at http://db.tidbits.com/
    Just search for "syslogd", that's where I found the info I passed along here.

  • Oracle 11g R2 consuming 100% CPU on execution plans

    Hi Friends
    I just installed oracle 11.2.0.1.0 on Windows 2008 Server R2.
    I got 4GB of RAM = 2536MB for SGA and 600M for PGA
    I'm running a processes that is consuming 100% of CPU ant its showed on execution plan of every statement this utilization.
    I have worked with disk_asynch_io parameter to FALSE and had no improvement on performance.
    Reading a doc relating to a bug I set up the dbwr_io_slaves to 4 but no changes.
    Now I'm stuck on asynch descriptor resize wait event for more than 4 hours.
    Any ideias os tips or experience about this issue?
    Tks a lot

    Well, Tks for your help guys,
    The problem was solved "almost" at all by disabling MEMORY_TARGET and SGA_TARGET and setting up all the memory parameters manually.
    This has eliminated the event "asynch description resize" and the overall performance of the DB has increased. I was able then, to complete my operation.
    I believe its a Windows bug or a poor design or configuration of mine. But at this time we are able to run the system well and fast enough.
    Tks a lot

  • Safari Consuming All CPU Power

    I just recently noticed that Safari seems to be taking a lot more processing power while browsing.
    When I click on a link, the fans start spinning faster, the little colored wheel cursor appears and I can see in Activity Monitor that the CPU usage for Safari goes to 100%.
    This happens every time I click on a link. It even happens if I hit the back button. It happened while I was typing in the post, since My Yahoo web page automatically refreshed on another tab.
    As you can see, I have a dual Power Mac G5 2.5 GHz with 4.5 MBytes of memory.
    This just started happening yesterday. I've never seen this before. From my previous PC days, I would say that I picked up a virus or some kind of Spyware.

    Over the last several weeks, I too have been noticing Safari taking up more system resources than it had in the past. I upgraded to Tiger the day it came out (from 10.2) and only began noticing this problem in early August. Not only have I seen an increase in CPU usage when running Safari, but I've also seen an increase over time of RAM usage. When I restart, RAM usage is under 30% with iCal, Address Book, iTunes, Mail, NetNewsWire, and a weather app running. Later that day after having browsed and done many other actions with only those basic apps running, RAM usage stays at or slightly above 50%. It often pegs out at 65% and again after restarting and re-opening those apps back up with the exception of Safari, RAM usage remains far below 50%. With my meager 800mhz processor, and all the memory leaking and CPU hogging going on, the fan is running much more frequently than it should.

  • Mail in 10.6.4 not usable: it consumes all CPU time and will not quit

    Mail application does not work properly.
    It eats up most of the available CPU time (till >300% on my machine), becomes unresponsive and will only quit when killed by a force quit in the Activity Monitor.
    I have only two accounts set up. One Gmail account and a google apps one.
    I used to synch with a Blackberry but now I synch directly through google apps.
    The problem was sporadic at best at first but has become the usual behaviour now. Major change has been installing 10.6.4
    I have switched to Thunderbird since Mail is not usable.
    Tx for any hint on how to solve this issue

    It seems to be a recurring issue with 10.6.4...there's probably not much mere mortals like us can do. I haven't found a solution. Try re-installing 10.6.4.

  • SQL Data Modeler on MAC consumes lots of CPU but still hangs

    Running data modeler version 3.1. on mac 10.7.3 - 64 bit both. Mac has got core i7 processor with 8Gigs or RAM, so no shortage of resources here.
    Got mail open as well as normal SQL Developer exploring the database tables and running queries. So plenty resources still available.
    I 'm experiencing intermittent conditions where I'm editing a card or entity properties and then developer goes into a "go very very very slow strike" mode. It consumes 99% CPU with average 40 threads running and approx 400 megs of memory consumed.
    It then takes for ages to respond to any inputs on the commit/cancel/apply buttons - more than 10 minutes! I once tried the "Force Quit" option - bad bad mistake. It lost all the task bar option - only had the "file" option on the task bar left!
    Anybody experienced the same or with a solution to this ?

    Hi I'm running Addressbook and cannot clear previous entry easily when searching my data base of around 5,000 contacts. 
    I prefer to view in All contacts on a double page spread with details on the right page.  Searching doesn't seem to work correctly in this view.
    It's always the second search that is problematic.
    I've tried typing over and all it seems to do is confine the search to the the entries that have come up for the previous search.
    I've tried to use the x to clear the previous entry and then type the next search, same problem.  The only way seems to be to move from "All Contacts" to "Groups".  Then the searched name appears and I can return to All Contacts to see full details.
    Surely three key press' are not the way it's supposed to work?

  • How to make data base link from oracle 11g r2 to microsoft sql 2008 express

    I need to make data base link from oracle 11g r2 to microsoft sql 2008 express to make replication between then
    please help me !
    I didn't know what is the user and password in the command which create database link

    To replicate data you can ude Database Gateway for ODBC or Database Gatewy for MS SQl Server. Please use the search engine of this forum if you ant to get more details about each product.
    Some SQl Servers are set up to use Windows authentication only. In this case you won't be able to connect to the SQL Server as Windows authentication isn't supported with the gateways. You have to make sure your SQL server is supporting username and password authentication - a common user is the "sa" user. Regarding the username/password, please get in touch with your SQL Server Admin.

  • Emacs consuming all of CPU

    Hello,
    I have a problem with the new Emacs 23.2.1 in that it consumes all of my CPU when running under X. In console mode it works normally. Do you also experience this?

    The same problem just happened to me today. I requested reopening of the following task in the bugtracker: http://bugs.archlinux.org/task/19397
    Removing the file .kde4/env/gtk-qt-engine.rc.sh as described in the 3rd comment to the above task did not solve the problem for me.
    I didn't try the cedet patch, because that's from 2006 and the 100% cpu problem appeared with emacs 23.2.1 which is brand new.

  • Cannot load any data from Oracle 11G data base

    Hi Gurus!
    We using SAP BI 7.0.
    We have a source system, which is an Oracle Data warehouse based on Oracle 11G data bases.
    We created the source system in the BI without any problem.
    The connection is open to the Oracle databases.
    We created data source in the BI (trn. RSA1), and when we would like to Read Preview Data (Display data source, Preview tab) we can't see anything.
    The system is working, in trn. SM50 we see the process is runing, but we can't see any data (we wait more than 5000 sec.)
    When we tried data load from the source system, we got a short dump with time-out (after 50000 sec.)
    Summarize:
    - the connection to the source system is OK,
    - the process is running
    - we can't see any Preview data
    Can somebody help us?
    Thank you.
    Best regards,
    Gergely Gombos

    We really need to know what errors or warnings the Cache Agent is reporting in the TimesTen ttmesg.log files, when an autorefresh fails, to be able to give advice. If the size of the datastore segment is 512MB (though you don't say how that is divided between Perm, Temp and Log Buffer) but you're only using 30MB of Perm, then on the face of it, it's not a problem in running out of memory. You say autorefresh doesn't complete when "there are a lot of updates on cached tables" - do you mean updates being done directly on the rows in the TimesTen cachegroups, by users? If so, it sounds to me like you have locking contention between the user updates, and the autorefresh mechanism trying to bring new rows in from Oracle. Again, the ttmesg.log should spell this out.

  • Performance problem in select data from data base

    hello all,
    could you please suggest me which select statement is good for fetch data form data base if data base contain more than 10 lac records.
    i am using SELECT PACKAGE SIZE n statement,  but it's taking lot of time .
    with best regards
    srinivas rathod

    Hi Srinivas,
    if you have huge data and selecting ,you could decrease little bit time if you use better techniques.
    I do not think SELECT PACKAGE SIZE  will give good performance
    see the below examples :
    ABAP Code Samples for Simple Performance Tuning Techniques
    1. Query including select and sorting functionality
    tables: mara, mast.
        data: begin of itab_new occurs 0,
                 matnr like mara-matnr,
                 ernam like mara-ernam,
                 mtart like mara-mtart,
                 matkl like mara-matkl,
                 werks like mast-werks,
               aenam like mast-aenam,
    stlal like mast-stlal,
         end of itab_new.
    select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
    into table itab_new from mara as f inner join mast as g on
    fmatnr = gmatnr where gstlal = '01' order by fernam.
    Code B
    tables: mara, mast.
    data: begin of itab_new occurs 0,
          matnr like mara-matnr,
          ernam like mara-ernam,
          mtart like mara-mtart,
          matkl like mara-matkl,
          werks like mast-werks,
          aenam like mast-aenam,
          stlal like mast-stlal,
    end of itab_new.
    select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
    into table itab_new from mara as f inner join mast as g on f~matnr =
    gmatnr where gstlal = '01'.
    sort itab_new by ernam.
    Both the above codes essentially do the same function, but the execution time for code B is considerably lesser than that of Code A. Reason: The Order by clause associated with a select statement increases the execution time of the statement, so it is profitable to sort the internal table once after selecting the data.
    2. Performance Improvement Due to Identical Statements – Execution Plan
    Consider the below queries and their levels of efficiencies is saving the execution
    tables: mara, mast.
    data: begin of itab_new occurs 0,
          matnr like mara-matnr,
          ernam like mara-ernam,
          mtart like mara-mtart,
          matkl like mara-matkl,
          werks like mast-werks,
          aenam like mast-aenam,
          stlal like mast-stlal,
    end of itab_new.
    select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
    into table itab_new from mara as f inner join mast as g on f~matnr =
    gmatnr where gstlal = '01' .
    sort itab_new.
    select fmatnr fernam
    fmtart fmatkl gwerks gaenam g~stlal
    into table itab_new from mara as
    f inner join mast as g on f~matnr =
    gmatnr where gstlal
    = '01' .
    Code D (Identical Select Statements)
    tables: mara, mast.
    data: begin of itab_new occurs 0,
          matnr like mara-matnr,
          ernam like mara-ernam,
          mtart like mara-mtart,
          matkl like mara-matkl,
          werks like mast-werks,
          aenam like mast-aenam,
          stlal like mast-stlal,
    end of itab_new.
    select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
    into table itab_new from mara as f inner join mast as g on f~matnr =
    gmatnr where gstlal = '01' .
    sort itab_new.
    select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
    into table itab_new from mara as f inner join mast as g on f~matnr =
    gmatnr where gstlal = '01' .
    Both the above codes essentially do the same function, but the execution time for code B is considerably lesser than that of Code A. Reason: Each SQL statement during the process of execution is converted into a series of database operation phases. In the second phase of conversion (Prepare phase) an “execution  plan” is determined for the current SQL statement and it is stored, if in the program any identical select statement is used, then the same execution plan is reused to save time. So retain the structure of the select statement as the same when it is used more than once in the program.
    3. Reducing Parse Time Using Aliasing
    A statement which does not have a cached execution plan should be parsed before execution; this parsing phase is a highly time and resource consuming, so parsing time for any sql query must include an alias name in it for the following reason.
    1.     Providing the alias name will enable the query engine to resolve the tables to which the specified fields belong to.
    2.     Providing a short alias name, (a single character alias name) is more efficient that providing a big alias name.
    Code E
    select jmatnr jernam jmtart jmatkl
    gwerks gaenam g~stlal into table itab_new from mara as
    j inner join mast as g on jmatnr = gmatnr where
                g~stlal = '01' .
    In the above code the alias name used is ‘ j ‘.
    4. Performance Tuning Using Order by Clause
    If in a SQL query you are going to  read a particular database record based on some key values mentioned in the select statement, then the read query can be very well optimized by ordering the fields in the same order in which we are going to read them in the read query.
    Code F
    tables: mara, mast.
    data: begin of itab_new occurs 0,
          matnr like mara-matnr,
          ernam like mara-ernam,
          mtart like mara-mtart,
          matkl like mara-matkl,
          end of itab_new.
    select MATNR ERNAM MTART MATKL from mara into table itab_new where
    MTART = 'HAWA' ORDER BY  MATNR ERNAM  MTART MATKL.
    read table itab_new with key MATNR = 'PAINT1'   ERNAM = 'RAMANUM'
    MTART = 'HAWA'   MATKL = 'OFFICE'.
    Code G
    tables: mara, mast.
    data: begin of itab_new occurs 0,
          matnr like mara-matnr,
          ernam like mara-ernam,
          mtart like mara-mtart,
          matkl like mara-matkl,
          end of itab_new.
    select MATNR ERNAM MTART MATKL from mara into table itab_new where
    MTART = 'HAWA' ORDER BY  ERNAM MATKL MATNR MTART.
    read table itab_new with key MATNR = 'PAINT1'   ERNAM = 'RAMANUM'
    MTART = 'HAWA'   MATKL = 'OFFICE'.
    In the above code F, the read statement following the select statement is having the order of the keys as MATNR, ERNAM, MTART, MATKL. So it is less time intensive if the internal table is ordered in the same order as that of the keys in the read statement.
    5. Performance Tuning Using Binary Search
    A very simple but useful method of fine tuning performance of a read statement is using ‘Binary search‘ addition to it. If the internal table consists of more than 20 entries then the traditional linear search method proves to be more time intensive.
    Code H
    select * from mara into corresponding fields of table intab.
    sort intab.     
    read table intab with key matnr = '11530' binary search.
    Code I
    select * from mara into corresponding fields of table intab.
    sort intab.     
    read table intab with key matnr = '11530'.
    Thanks
