Database query performance issues

• Developer SQL vs TOAD - query performance issue

  Someone pointed out the same queries are run slower in SQL Developer and TOAD. I'm curious on this issue, since I understand Java is 'slow', but I can't find another thread on this point. I do not use TOAD, so I can't compare...
  
  Can it be linked to the amount of data returned by the query? What could be the other reasons for the SQL Dev works more slowly with a similar query?
  
  Thank you
  Attila

  It occurs to me also that TOAD always uses the equivalent of the 'thick' JDBC driver Developer SQL can use 'thin' driver or the 'thick' driver, but the connections are usually configured with the pilot "thin", since you need an Oracle client to use the 'thick' driver

  The difference is that the 'thin' drivers are written entirely in Java, but 'thick' drivers are written with only a small Java that calls the native executable (that's why you need an Oracle client) to do most of the work. In theory, a thick driver is faster because the code of the object should not be interpreted by the JAVA virtual machine. However, I heard that the performance difference is not that big. The only way to know for sure is to set up a connection with SQL Developer to use thick driver and see if it is faster (I would use a stopwatch).

  Correct me if I'm wrong, but I think that if you use 'TNS' as your type of connection, Developer SQL use thick driver, while someone is using the default value, the type of ' basic' connection the thin driver. Otherwise, you need to use the connection type 'Advanced' and type in the JDBC URL custom for the thick driver.

• performance issue with the Oracle SQL query

  Dears

  Good evening

  I am new to begin to use Oracle SQL, I have a sql query which takes longer to run in production.

  Each table in the query contains 1.2 million records and DBA suggested using the "Oracle - tips. I don't have good knowledge on this subject and the difficulties to implement this advice for imrpovise performance. In the product the jobs Informatica are failed and stuck with this problem of query performance.

  I ask this forum for an emergency for me to solve this problem by using "advice". kindly help me.

  Try to remove all except one of the calls apex_item.select_list_from_query, and then rewrite this one to use subquery factoring. Now compare at the same time for the same query with and without subquery factoring. In addition, 500 lines is a realistic number that you expect someone to change?

• VCO performance issue?

  We have upgraded a VCO stand-alone server to version 5.5.  Expand the folder objects to data center and host when using vCenter 5.5 plugin can last up to 10 minutes.

  Upgrade process

  1. export the packages and configuration

  2 order services and uninstalled the application

  3. has taken a backup of the MS - SQL Database and and got up a new database in its place

  4. install the new version of the application 5.5

  5 import the configuration and the packages in the application.

  Has anyone seen this behavior? or better yet have a fix for this?  5.5 seems to be significantly slower than version 5.1, we were in front.

  Specifications of the system running virtually...

  Win 2008 R2

  2 CPU i7

  12 GB OF RAM

  The Java heap size has been increased to...

  maxHttpHeaderSize = "163840.

  It is a new version of technical overview of vCenter plugin available here.  Version of technical overview of VMware vCenter Orchestrator plug-in for VMware vSphere 5.5.x

  This version fixes some performance issues related to vCenter inventory and plugin starting aceptinag of workflow as vCenter parameter objects...

  It will be useful.

• Date performance issue

  Hi guru,.

  I use 11.1.6.8 OBIEE. One of my report is to have performance issue when I dig in that I found that the date filter not applied in the code SQL generated for send DB, due to which there is table scan, but strange thing is that when she displays data based on the Date range filter. It only occurs with the date dimension, all other dimensions are working properly. I'm not sure what he is missing.

  I found the problem, it is in the characteristics of the DB. I click query to get the DB position it works now.

• Will there be any tools avialable to the on query performance tuning

  Hello
  
  How to tune a database query?
  Suppose that there are basic query "select * from emp where empid = '1101' ';"
  
  Y at - it all avilabale tools to suggest performance Tuning on a query?
  
  How can I resolve this application, and what is the best approach on this?
  
  Please share your ideas and thanks.

  Oracle provides tools such as SQL Trace and TKPROF. For the information on a SQL query.

  But basically, you should know how oracle works. You must be aware of the different access plans and know why they are being used.

  You need to know when to use an index and when not to use a.

  There are many more. Best thing for you would be to start reading the document.

• Untangled RoboSource slow performance issues

  Hi all
  
  I'm a noob-Robo (noobie, novice, etc.) but not new computers and databases and others. We have a team of 5 authors are all working on separate projects but under even version RoboSource Control. We know some questions serious performance: projects can take over an hour to check outside or inside. not all users can see projects; "Rename" do not get rid of the old actually prefer a copy under the new name (?); etc.
  
  I'm trying to 'normal' basic behavior for RoboSource Control as well as some best practices for multiple users. I wonder if there is something more in depth to describe the RoboSource Control engine and possibly maintenance tasks to help what seems to be a jumble of nodes that are not all necessary, too many users "admin", etc. I expect that the "cleansing" will solve many of our problems.
  
  So, rather than go in each problem in the forum, I prefer to find the right resource and to tackle this thing by iteration.
  
  Thanks for your useful suggestions
  
  Don

  I wanted to update the forum about this performance issue. After further investigation, we note that serving PC server worked for 6 months without interruption. In addition, she has 512 MB of RAM, but the ROBOSOURCECONTROL service consumed 350 MB of it. The rest of the system resources were probably permutation are busy. A reboot which is brightened and RSC performance is splendid - from 30 to 60 minutes, until about 15 seconds for a GET or a check-in.
  We suspect there is a memory leak in CSS, but I can start a separate thread for some tips on how to identify and report a bug for this package.

  Thank you all

• SQL query performance

  I have a table that lists the users visits to pages on our website. The information takes the type of structure within our next record table:
  
  VisitID | IDVisiteur | VisitPage | VisitDate
  Index | UniqueID. VisitPage | Date/time
  
  I need to get to IDVisiteur who visited in a user defined date range for a report that is to be written, and then get a count the days of separate visit that each user has visited our website. I have a request of work attached that will get me the result set, I want, but it's so _very_ slowly. Query Analyzer it shows that 84% included in table scans. I hope someone has a suggestion on how to optimize it. I am currently working on a MSSQL 8.0 Server, so I have no access to the function of tronque() that I would prefer to use on the dates, but that's a minor inconvenience.
  
  Thank you

  You have an index on visitdate?

  Visitdate contains real-time, or are all the parts of the time 0:00? If they are all from 00:00, you don't need the convert function. Otherwise, you might have better luck by selecting all data from your database and using Q of Q for the counties.

  Dan there on this one. Looking at the design table index was absent. Once I added an index my query performance dramatically, improved enough so that I don't have a lot of worries more. Thanks for the suggestion.

  The server has 16 GB of Ram... way means that, due to limitations of 32-bit on windows only 4 GB of Ram was used and the 12 remaining GB is inactive?
  What is the proper way to tune?

  There are restrictions on how the memory beyond 4 GB can be used by Oracle. As far as I know, the memory is reserved for the buffer cache.

  Not all memory below the 4 GB limit is available for programs. Some of this memory is laid out in memory of the device, such as the video cards, RAID cache on board, etc., and some of the memory Windows is needed to track the objects window, icons, etc. Although it is possible to back up 2 GB per process limit to 3 GB, making Windows limit to use for its own purposes the memory that remains after the memory is drawn to embedded devices, and I think that the Oracle Metalink site does not recommend trying to go up the by the limit process completely to 3 GB. And this low by the process boundary should be reserved for the memory window. Your current value of pga_aggregate_target should be checked, because there is no way that the apparent present value could enter into the available memory.

  I agree with Martin - the best way to take full advantage of the memory is to pass on a 64-bit platform. Most, if not all the memory limit headaches disappear on a 64-bit platform. Of Windows 2003 Standard edition supports up to 32 GB of memory, this could be an option for you. It may or may not be a huge effort, but this means system loss of time (which can be considered a reason to call it a huge effort). You will probably find that the server, if less then three years, will support a 64 bit version of the operating system, but check the 64-bit versions of all the drivers are available and consider replacing hard disks containing the operating system if you need to return to the current operating system.

• Performance issue of SAP with Oracle 10 on Sun SPARC T5240 server

  Dear friends,
  
  We have a performance issue after the migration of our basic system of SAP ERP 6.0. To new servers, we moved a month ago.
  The report of EarlyWatchAlert SAP response time of CPU is too high, although the CPU utilization is never more than 5%,
  
  The current system is:
  
  Database server: Sun SPARC Enterprise T5240 Server - 2 CPU´s with 6 core wire 8, 1.2 Ghz 32 GB RAM
  and we use a different identical server configured as an application server.
  
  Database is Oracle 10.2.0 and Solaris 10 operating system.
  
  The problem is CPU average response time is 450 ms and maximum CPU load is 5% percent.
  
  Configuration prior to migration with the old servers, we got the answer of CPU: 150 ms and max CPU load: 50%.
  Old configuration: 2 X HP rp3440, 2 X PA 8800 (2 core, 1.0 GHz) CPU.
  
  You have experience with a similar situation, setting that could be bad for server CPU´s not making full use?
  or you know any similar configuration for benchmark?
  
  Thanks in advance
  
  Uzan

  The new server's processors in Niagara? If so you could run in the known performance issue identified in MOS Doc 781763.1 (Migration of fast single machine threaded CPU to CMT UltraSPARC T1 and T2 causes an increase in the CPU reports)

  OAS 10.1.0.3
  1.5 GB of RAM on my PC
  
  -J' planned a workbook with 1 single worksheet that takes 2 minutes to run. The table generated in the database to store the results from 19 columns and rows to about 225000 (I know that's a lot, but it is what the customer needs).
  
  -When I opened the workbook, it takes about 2 hours to recover the data. The data is retrieved in groups of 1000 and at the beginning, the lines are read much faster than at the end. There are also 15 minutes more to build the crosstab. So overall, it takes 2 hours and 15 minutes for the crosstab display on my screen.
  
  Can someone explain to me:
  -Why does take so long?
  -What can I do to improve the execution other than changing the application or displaying the results in a regular tab? Is there some setting that I can do on the database of the Oracle Application Server?
  
  Note: I have reproduced the worksheet in a simple tab and demand it. The table generated in the DB to store the results is the same and it takes only 2-3 minutes to open this spreadsheet and extract all lines.
  
  
  Thank you!

  Hi Mary
  If you have 225 000 lines in your basic spreadsheet, then it will take a lot of time to produce a crosstab. The reason is that Finder can not calculate how many buckets he needs until he has read all the data. I can almost guarantee that with 225 000 lines to read and manipulate that you are short of memory.

  You might be better suited someone create and populate a table with the results you need rather than try to get the discoverer to calculate values in crosstab on the fly. If the final result of the crosstab is a few lines of aggregated data, then this is what is right for your table. The advantage of using a table and a few SQL (or PL/SQL) is that you will not be using your local computer during the aggregation / sorting phase. Don't forget a crosstab also sort based on the values in the left columns, the columns you have aggregations (buckets) you will have and most necessary sort. Using a table, you can index or even partition the results that will make for a much faster recovery.

  As a tip, recommend Oracle, confirmed by myself during the exhaustive tests, no do not build large paintings to double entry due to the performance of touch that you will have. The tables are much more efficient because you can pull back x lines at once. You can't do that with a crosstab and all values must be read before that whatever it is is displayed.

  Does that help?

• HP Elitebook 8570p - Windows XP USB very slow and the transfer rate performance issues.

  Hello. I was wondering if anyone else knows some performance issues with the HP Elitebook 8570p and Windows XP Pro - SP3.

  I get a VERY slow start, general poor performance (waiting time when opening files and programs).

  I asked to burn in tests that show that everything is good.

  USB transfer rates are VERY slow (tried all ports of a Seagate FreeAgent USB drive, which works fine on other laptops etc.) for example a 30-minute transfer a 7gig single file of the USB HD on the desktop. Only 3 minutes to do the same on another laptop.

  I think there are problems with the drivers, like Windows 7 works very well and does boot from a bootable USB.

  USB transfer rate are also good when starting from a Windows boot environment.

  I installed HP SoftPaq Download Manager, and all the drivers are up to date.

  Hello:

  I think outside of the box here... Select the Intel (r) 7 Series Chipset Family SATA AHCI Controller instead.

  If it does not, I raise the white flag.

• Performance issues when coming out of sleep

  I recently built a gaming PC. On Christmas day, I finished putting the thing together. It has an Intel i7-4790 CPU running Intel HD Graphics, 8 GB of Corsair Vengeance RAM, an Asus Z97 - A Mobo and a 2 terabyte Seagate HDD. I installed Windows and put everything in place. Then a week later, my MSI GTX 970 arrived in the mail.

  So, I take the thing to sleep and decreases the performance of the whole thing. Videos YouTube stutter, simple as games fight of World of Tanks to run at its usual rate of 60 fps. To avoid this, I simply restart my comp and then it works fine. performance is back to normal.

  A few weeks, Windows gave me a message on one of the Nvidia drivers causing performance issues when you wake up from sleep. I don't think a lot of it and rejected it. I'll try to reinstall all my Nvidia drivers. I uninstall the Intel HD graphics driver a few days ago and has not changed anything. I would appreciate an answer to this problem because I would like to continue to use the "sleep mode" because it consumes less energy and prolongs the life of my case of LED. Thank you!

  In order to diagnose your problem, we need run Windows performance toolkit, the instructions that are in this wiki

• Smartphone blackBerry Storm performance issues (and suggestions)

  I want to start and say that I don't like my phone.  When it works (which is most of the time), it works fine.

  But there are certainly problems of software.  As a software engineer, the OS has some memory serious management problems.  This seems to cause most of the problems I'm having with the phone.  I'm running the latest Verizon S/W (v4.7.0.148).

  Problem #1:

  I am a paranoid person.  There are a lot of personal information on my phone, I have currently international calls helped that I need this feature.  So to protect me my phone is locked when it is the case or after a period of inactivity time.  It is a good practice.  Part of the draw to the fate of the Blackberry is the security that you can configure on the device (I'm not paranoid enough to allow all the protections of encryption - yet).  Problem of the storm is that it can take 1 to 5 minutes to get the phone unlocked when unholstering.  It is not an exaggeration.  As the performance of the memory gets worse, time takes more time.  If I had to make an emergency call, it could be the difference between life and death.  5 minutes is a long time to wait to call 911.  This must be corrected!

  Problem #2:

  The phone must be "reset" once a day to remember "lost."  It is just poor programming.  I don't know if this problem of BB OS or Apps I'm running, but in both cases, this isn't fair.  After the reboot if I go to the display of memory under options I could have about 3-5 MB of free memory.  After a few hours of use, this will almost always '0 '.  I installed MemoryUp Pro, which seems to have extended the period of time between the battery grips, but I still don't think we should ask all owners of BB Storm to pull there battery once a day.  The other answer I get is "do not run so many Apps.  I get all my applications when finished.  Are the only ones that I continue to turn: Blackberry Messenger, Yahoo Messenger, Google Talk and Google Maps (Latitude).  Other applications running, you can't get out (phone, browser).  I tried doesn't work is not the 'optional' tricks and performance has not really much better.

  Problem #3:

  Missed calls.  This is probably related to problems of memory above, but if the storm can be used as a phone, then I should buy something else.  Although the occurrence of this problem has gone down because I installed MemoryUp Pro and perform the reset once a day, sometimes still about 1 to 5 times.  It takes so long for the phone to 'wake up' when a call comes in (especially if it is holstered), at the time where I hit "Answer", a call has been Messaging voice or even worse, the phone doesn't ring at all.  All I get is a notification of appeal lacks the 'unknown number '.

  Problem #4:

  Battery performance could be improved.  The battery that comes with the storm has about 24 hours on 24 with the Radio and Bluetooth.  Really, this isn't a problem if you know it.  I solved the problem by buying a 2700 mAh battery for extended life of BoxWave I use when traveling.  Makes the storm bit bulky, it will give me 2-3 days of life.  I don't know how this could be improved if not

  I hope that the developers of RIM are trying to solve some of these performance issues.  Certain tasks should be a higher priority as they seem to have (like phone & Unlock).
