Poor performance after upgrade

• SQLDev poor performance after upgrade to DB 11 g

  I have a database of 10 large short g and Developer SQL works well with. But I cloned deployed this DB at 4 new hosts and DBUA to upgrade to 11.1.0.7... and now Developer SQL runs horribly on all four. It takes 2-3 minutes to return a list of 'other users' 11 g vs 10g. The plan to explain the SQL shows 100% CPU usage, but with a cost of 38, which confuses me. Here are the Sun T5240 systems with ample CPU and memory to spare.
  
  I've updated the statistics of dictionary with no effect...
  
  Someone has ideas... is there some kind of SQL Developer framework I'm missing or something like that?

  Solution: Look for sqldeveloper.jar and extract schema.xml file. Edit the file to replace the two versions of the query as follows

  Select
  * from (SELECT username,
  10 OBJECT_COUNT - wrong County
  OF SYS. ALL_USERS to the
  WHERE AU. USER NAME! = USER)

  Replace the xml file in the jar and the problem should go away.

  P.S. A customer problem that reported that it depends on the user having privilege "select any table". It is so in your case?

• Slow IO performance after upgrade to vSphere 5

  Hi all

  I have a problem in our lab environment and I type some other brains in the community .

  First of all a brief overview:

  2 x Fujitsu RX300 S5 (FC HBA LP1150)

  1 x Fujitsu RX300 S6 (FC HBA LP1250)

  2 x Brocade 200E

  1 x Fujitsu Eternus DX90 (CF)

  1 x Fujtsu Siemens FibreCAT SX80 (CF)

  All devices are running with 4 G FC.

  Last week we updated our servers with the latest firmware (included HBA) and the latest vSphere 5 (updated 01 and the last patch-bundle). Everythings seems to run fine, after I've got svmotioned a few servers to get an empty data store. A few small servers (each. approximately 30 GB) need hours to get to the target data store. With CLI, I created a vmdk eagerzeroedthick to test the performance on our DX90. It took almost 10 minutes to create a 10 GB vmdk (about 17 MB / s; flow even showed DX90 performance monitor). I did the same on the FibreCAT and this storage is running normally with 170 MB per second.

  Now lets get things I did to track down the cause:

  1. I connected directly the first server with the DX90 (to avoid the fc switch)-> problem still there
     
  2. I went down the HBA firmware to version previos-> problem still there
     
  3. I installed the 4.1 vSphere update 02. I put only the investigation period and did test of 10 GB-> problem disappeared. for 10 GB, it took 39 seconds which is nearly 300 MB per second
     
  4. I installed (new installation) of the first version of vSphere 5-> surprise, the problem here is once again
     
  5. I installed ESXi 4.1 (I tested again and it took again 39 seconds for a 10 GB vmdk) and upgraded to vSphere 5-> problem is still there
     
  6. I tried all the way air, Fujitsu drivers customized for Emulex HBA and LUN parameters
     

  Writing performance monitor shows response time between 700 year 1400 ms and 17 MB per second with vSphere 5 to the DX90. With version 4, it is between 0 and 60 ms and nearly 300 MB per second. Only the SX80 works very well to any version (not support ALUA). Each unit works with the latest firmware.

  It is without doubt vSphere 5, what causes the problem. I can't find clues in newspapers or VMware KB.

  Does anyone have an idea or the same problem? If I can't find a solution in the coming days, I propose to prosecute.

  Thanks in advance

  Hi Martin,

  There is a similar discussion in a German community in vmware.

  The solution was simple, your table does not seem to support VAAI.

  If you follow the following article to disable VAAI.

• ProBook 470: ProBook 470 poor WiFi after upgrade to Windows 10

  Hi all

  There are so many issues report on WiFi on Windows 10 problems, but I'm not really mine.

  I'm running the ProBook HP 470 with WiFi Atheros 9000 series card. It worked fine with Windows 7 Professional 64 bit.

  A couple of weeks, I decided to upgrade to Windows 10. Everything works fine, except the WiFi. I can connect to the WLAN and network speed and the signal strength is perfect, but after a while (minutes or even hours), he falls abruptly to the bottom and my router WLAN even States disconnected, but he'll fix itself after a while. I can force the "self-repair-speed" of disabling and enabling WiFi again.

  But, this is no good solution, WiFi has to work reliable all the time when not moving and it work perfectly with Windows 7. I was hoping that Microsoft and hardware vendors manage drivers after one year of version 10 of Windows, but seems not to be the case.

  I have already installed the latest driver for HP download site, but it is already a year old, and it was the same thing as Windows / Microsoft has done while Windows Upgrade. Therefore no change to be expected.

  Before that I go down again to Windows 7, what can I do? There are a few other pilots who could interfere with WLAN and might not be updated? (More of the WLAN driver I don't have other day manually because I count for the Windows upgrade process.)

  Volker

  The laptop is to date, according to the release of Windows 10.

  Anyway, it doesn't work well, that's why I decided to downgrade to Windows 7. Now it works again as it is supposed to.

• SQL very slow Performance after upgrade.

  We have recently upgraded to 10.2.0.5 for 11.2.0.1, and the performance of some of our queries SQL slowed considerably. For example, a query that works almost instantly in 10 g takes more than 30 seconds to 11 g. When I run an autotrace, the LAST_CR_BUFFER_GETS in 10g is 1067 and 11 g, it's 621006!
  
  I don't know why the exact same query would produce different results. I'm sure it's a matter of adjustment, but any ideas on where to start would be appreciated.

  This command will gather his stats, but the default values can be different between 10g and 11g. You should check out what they are. Here are the ones I have change:

  select dbms_stats.GET_PREFS('AUTOSTATS_TARGET') from dual;
  select dbms_stats.GET_PREFS('CASCADE') from dual;
  select dbms_stats.GET_PREFS('ESTIMATE_PERCENT') from dual;
  select dbms_stats.GET_PREFS('METHOD_OPT') from dual;
  select dbms_stats.GET_PREFS('NO_INVALIDATE') from dual;
  select dbms_stats.GET_PREFS('GRANULARITY') from dual;
  select dbms_stats.GET_PREFS('PUBLISH') from dual;
  select dbms_stats.GET_PREFS('INCREMENTAL') from dual;
  select dbms_stats.GET_PREFS('DEGREE') from dual;
  

  And then I change them to:

  EXEC DBMS_STATS.SET_GLOBAL_PREFS('AUTOSTATS_TARGET','ORACLE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('CASCADE','TRUE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('ESTIMATE_PERCENT','100');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('METHOD_OPT','FOR ALL COLUMNS SIZE 1');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('NO_INVALIDATE','FALSE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('GRANULARITY','ALL');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('PUBLISH','TRUE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('INCREMENTAL','TRUE');
  

  Your preferences may be different, but we do not use histograms and we always 100% of the data samples. Find out what the other parameters in the Oracle documentation.

  Good reading on this topic [url http://www.ora00600.com/scripts/statistics/restore_schema_stats.html] restore schema stats and this one on [url http://www.ora00600.com/scripts/statistics/gather_system_stats.html] collect statistics of the system.

  When you gather stats, you may need to clear the shared pool afterwards so that they SQL request are difficult, analyzed again and use the stats again. Use the ALTER SYSTEM FLUSH SHARED_POOL but probably better to do so in a period of low activity.

• After upgrading to 11.2.0.1 performance issues

  Hello
  We improved one of our dev from 9.2.0.6 to 11.2.0.1 databases. It is one of our databases of mart reports and we ETLs it running. We have about 25 ETLs that run and after the upgrade, some of them perform horribly. ETL taking 5 hours earlier, more than 15 hours now and some that lasted 7 minutes, running for 4 hours about after the upgrade. We have made changes to the settings and we have seen significant changes to most of the ETLs. Earlier, we had pga_aggregate_target set to 2000M. It was after we changed that to 1000M and the optimizercost_model io, the value we saw the best performance on some of these ETLs. However, when we tested the ETL which took 5 hours to pre-upgrade, we see that he has not done even in 15 hours now. One thing we did was we don't collect table statistics after upgrading. In fact, the statistics we have are about 4 years old and never collected new, since we did not have a problem with the performance. Would you suggest collecting statistics?

  Hello

  Would you suggest collecting statistics?

  Yes, the optimizer changed much since Oracle 9.2, so you should have reliable statistics. Refresh using the dbms_stats package.

  Otherwise, you can use the Statspack or various tools like ASH, ADDM, setting SQL that can help you to set up your database:

  NB: Some of these tools need a specific license.

  Hope this helps.

• Poor performance of Firefox after you apply the latest Microsoft Updates (Win 7 x 64); all solutions?

  Recently, I updated to Firefox 27 and noticed really horrible performance (Manager tasks indicates FF connecting a carrot, frequent "Firefox is not responding messages", even strikes in late development in the URL bar). It's on an Ideapad s205 (AMD E450 APU, Win 7 x 64, 8 GB RAM, SSD) who has always had pretty decent web browsing performance for a low end machine.

  At first, I blamed FF because poor performance coincided with the update to version 27, but now I think that the first cause to be a recent Microsoft Update. The reason is that my wife has a laptop with a same low-end APU (APU C60, hard drive 5400 RPM, 4 GB of RAM, Win 7 x 64), and she was getting much better performance with FF27 until I applied a backlog of some 90 + updates. Now she suffers from the same poor performance I am and she is pretty p * ssed at home.

  Interestingly, I have two WIn 7 x 64 Intel computers to office who have 27 FF and are fully patched, and performance are very good. Maybe this problem is specific to AMD APU.

  Any thoughts? I tried to turn off the backend Azure with some comments in this forum, but makes little or no difference.

  Thank you!

  Success! 32 FF seems to have solved my problems of performance. Thank you!

• Trackpad MacBook Pro late 2011 does not not after upgrade

  I just update the OS in my MacBook Pro (late 2011) which worked perfectly well 'El Capitan' to 'Sierra '. Everything went, smooth and pleasant. but now, the trackpad is completely erratic, is in itself (such as move and open programs like possessed). I tried several suggestions from apple such as checking for updates, check the settings, delete all the gestures, etc. I'm assuming that the material is very well that was perfectly fine yesterday... any suggestions please help.   -Note; I have to use an external mouse, and the latter is very well.

  Hello Med_,

  Thank you for using communities of Apple Support. It is my understanding that after upgrading to Sierra, your MacBook trackpad has become erratic. I know that my trackpad is an important part of my daily use, I can certainly understand your concern. I'm here to help get this resolved with you.

  You did an excellent job so far! Then I recommend the system management controller (SMC) reset. This system can solve some unexpected behaviors. Follow the steps below:

  1. Stop the Mac.
  2. Unplug the MagSafe from Mac power adapter.
  3. Remove the battery. (Learn about removing the battery in the MacBook and MacBook Pro computers).
  4. Press and hold the power button for 5 seconds.
  5. Reconnect the battery and the MagSafe power adapter.
  6. Press the power button to turn on the Mac.

  The LED on the MagSafe power adapters could change State or temporarily disable when you reset the SMC.

  Reset the management system (SCM) controller on your Mac.

  If the problem persists, test this problem in safe mode. This will allow you to exclude the software as the cause. To help get started in safe mode and additional steps, use the steps and the link below:

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

  After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

  To leave safe mode, restart your computer without pressing any keys during startup.

  Try safe mode if your Mac does not end commissioning

  See you soon!

• HP ENVY 17 Notebook PC TS: very low volume after upgrading to 64-bit windows 10, beats box has been deleted.

• ITunes skipping after upgrade to clean boot of Windows 7 64 bit HP Pavilion m9500y

  I recently updated my m9500y to vista 64-bit home premium to windows 7 Professional via an upgrade to boot. Since the update iTunes ignores intermittently. Can I close iTunes and reopen it and it will play OK no problem jumping. Sometimes it takes to open and close the program several times before that it will play correctly no problem jumping.

  I won't have the same problem with Windows Media Player as I've seen in other posts on this and other forums for the problem of Itunes jump.

  I completely uninstalled iTunes such as recommended by HP before you perform the upgrade to windows 7 and I have all the HP windows 7 and the Microsoft updates, including the drivers and firmware.

  I even tried to uninstall completely the 9.2.1 64-bit version of itunes, including registry keys and installed the previous version of Vista 64 bit which worked perfectly before the upgrade. However, I still had the same problem.

  Just in case my driver realtek HD audio version 6.0.1.5910. I do music professionally and HP Smart Media and Windows Media Player simply do not cut it. I have my iTunes works properly all the time.

  This is the only problem that I have. Everything else works perfectly.

  I did the same windows 7 Professional upgrade exactly the same way on my Inspiron 1545 Dell 64 bit machine and I do not have the itunes problem to jump on this machine. I hope someone has a solution.

  I think, with all posts on this problem on this and other boards of the HP HP machines he owes to its clients to have their engineers and programmers reach a solution. I spent at least 50 hours on the problem.

  Thanks for the suggestions, however, neither worked. However, all is not lost. I finally found the solution and cause, and the problem is solved. It turns out that some third-party modules were cause of conflict with itunes. I found this link: http://support.apple.com/kb/HT2292?viewlocale=en_US to Apple support.

  I give detailed instructions on the way which we MSCONFIG to solve conflicts in Windows Vista and 7, which could be the cause of problems with iTunes. After change startup programs and services, then by adding them one at a time after restarting whenever I finally was able to hide the indentify the third specific add on that was originally my itunes jump like a needle to jump on a vinyl record when the weight of the pick-up arm is set to lowest.

  In my case, it's a tool bar add-on in my Explorer window.

  I also checked the other this fix from Apple and would suggest that anyone having a problem with itunes to jump or other problems itunes with Windows 7 to do both. One of the link above and this one: http://support.apple.com/kb/TS1362

  So, the bottom line is the problem of: Itunes to jump after Windows 7 64 bit clean upgrade HP Pavilion m9500y, boot IS NOW RESOLVED.

• Qosmio X 500-10T: what setting should I change after upgrade SSD?

  Hello community,

  I'll upgrade my Qosmio X 500-10T (currently with two 512 GB drive HARD, although only has data on it) with a Samsung 840 series 256 GB 2.5 in SATA SSD Pro and then perform a new installation of Windows 8.

  My question: what settings should I change once the switching plate?

  I think there may be some settings in the BIOS that may need to be changed.

  Also, it is recommended to remove the second HDD due to possible performance issues along the SSD?

  Are the drivers on the windows-compatible laptop computer support page 8?

  P.S. I read on UEFI, is there a way to update/upgrade existing in UEFI BIOS?

  I know it's a lot of questions, but any help is appreciated.

  Thank you

  Hello

  > My question: what settings should I change once the switching plate?
  > I think there may be some settings in the BIOS that may need to be changed.

  Usually, you do not need to change anything in the BIOS.

  > Also, it is recommended to remove the second HDD due to possible performance issues along the SSD?

  You may notice poor performance while moving or copying data from the SSD hard drive or SSD HARD drive.
  but to think that you can keep the HARD drive in the 2nd Bay for other files.

  > Are the drivers on the windows-compatible laptop computer support page 8?
  Do you think that some drivers Win 8 there?
  If so, they are...
  otherwise, you can try some Win 7 drivers in the frame to win 8

  > . I read on UEFI, is there a way to update/upgrade existing in UEFI BIOS?
  If you're going to see an update of the BIOS for the Qosmio X 500 with a serial number 6. XX or later version, then it would be a version of BIOS released to win 8 too

  TRDC reminder and Toshiba Recovery Disc Creator after update to Wins7?

  The TRDCReminder program found no "revival of the computer.
  Toshiba Recovery Disc Creator program was created and incomprehensible?

  If what these program how to recover your computer in case of failure?
  TEMPRO works in Win7?

  Thank you very much.
  With greetings.

  Igor.

  Hello Igor

  In my opinion, you must create recovery disk before upgrade you to Win7. I did the same thing.
  Later, if something goes wrong, you can use your disks and install Vista using the created recovery disks.

  I don't understand why you want to wait and create these disks after upgrade. This recovery creator disc doesn t create recovery image in the current state, but always the same recovery image, you got with your laptop.

  TEMPRO should work in Win7 too.

• All-in-one Officejet 5610: function Scan lost after upgrade to Yosemite

  Lost the ability to analyze after upgrade, print, and copy works. Have already done everything suggested by Double-U-di in the Mac OS 10.10 post Yosemite and HP Printer Support posted on 30/10/2014: checking for updates Apple, printer removed from the queue, add printer back, reset the printing system, removed the HP software, repair disk permissions * manually installed HP printer drivers v3.0 and added to the queue printer. No change, printing & copying ok, but the scanner does not.

  During approval of the repair disk found a number of problems related to printing and presumably repaired, had more to do with the ' should be 80, group is zero ", but others as well.

  Anyone know what I can do, short of buying a new printer? I realize, it's a dinosaur - always attached via the USB port, but she worked just beautifully before the upgrade.

  Hello @DrBucky,

  Welcome to the Forums of HP Support!

  I understand that you are not able to scan from your HP Officejet 5610 all-in-One Printer to your computer Mac OS X 10.10. I would like to help you to solve this problem today. Thank you for all the troubleshooting steps you tried before reaching out for support. You have completed almost all of the recommended steps. However, the order in which the steps have been completed can cause some problems. Therefore, I will be having repeat you some of these measures to ensure that the appropriate driver is being used.

  5. click on the area of use or with the help of Print and then select the name of your printer on the shortcut menu. Ensure that the Officejet driver is selected.

  

  6. click Add to add the printer to the list.

  -Source

  Once your printer is properly added to, please try to scan the image. For instructions on the three supported methods of scanning without HP software please click here. The support document indicates that it is for Mac OS X 10.8 but the steps are the same for Mac OS X 10.10.

  Please let me know if a retry of the procedure described in this new order solves your problem of scan. Good luck!

• 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]
