  Of course, it's slow.

  This is the perfect example of HOW not in PL/SQL code.

  Cursor fetch in PL/SQL loops are wrong 99% of the time. When you want to process the data in the database? Use SQL statements. Use SQL statements. And use SQL statements.

  No PL/SQL.

  Use INSERT... SELECT, MERGE, UPDATE (SELECT) and other SQL constructions.

  When you want to change it manually (where you manage the treatment), run this SQL via DBMS_PARALLEL_EXECUTE.

• I made a disk defrag on the guest computer and now VM won't start

  Hi, I stupidly done a disk defrag on the guest computer and now VM won't start. I have attached the log files you. Please help me.

  Post edited by: a.p. - the moderator Note: branched out in a new discussion

  This can make things more difficult depending on the current state of the virtual machine.

  What you should do at this point - unless already done--is to backup/copy of files of all VM to ensure that you have a way to go back if things don't work as expected. The next step is to find out if it is possible to free up space on the D: drive, so that the virtual machine does not have to be moved (move the files could be unnecessary snapshots). If there is enough free space on the disk, use the file attached configuration (.vmx) to replace the damaged one. Ensure that VMware Workstation or at least tab of the virtual machine is closed when you do this to ensure that the replaced .vmx file is reread. If things work with the replaced files, consider deleting snapshots that you no longer need. This will not release disk space only, but can also improve the performance of the virtual machine.

• SQL Server, vmotion and vmwaretools

  Hello

  I have upgraded some hosts recently to 3.5 U4 and had no problems at all.

  Today at 14:05, I started a vmotion of SQL server 2003 with 4vcpu and 12 GB of RAM. The server is heavily used noit. To 14:09, the vmotion did, but suddenly Transactions per second achieved a huge level that they've never been before. I'm not a SQL, so I wonder if these two events could be related.

  The SQL box is placed a U3 to a U4 server after the vmotion so he showed vmwaretools must be upgraded...

  Any possible relationship in this?

  Hello

  I would like to start looking at the SQL logs, newspapers, newspapers in VMware and vmkernel journal BONE. Try to determine what happened. However, remember that when you VMotion, VM are stalled for a bit at the end so in memory use could be copied. That being said, perhaps linked the sudden increase in "catch-up"? How long did the VMotion

  Either start within the guest and work your way on the correlation between your papers all the time.

• 16 disks table PS5000 Sata - Raid for better performance and more capacity

  Good afternoon all

  I studied the whims of the various raid options and I was wondering if anyone has any practical idea using tables PS5000 SATA?  Basically, the table will backup disks to virtual machines as well as Raid would be preferable for the performance and capacity?  I was thinking 50 Raid or Raid 6, that the table is at a distance of my office in one data center so that there could be 2 failures before the disaster...

  Thank you very much

  Eric

  Hi Eric,.

  'best' depends entirely on the expected I/O model.  Small random writes should use R10.  RAID50 is usually a good compromise on space and performance.  But it has the risk of a double RAIDset faillée down.

  Another factor is that the PS5000 is end of life.  No support, firmware or parts of long term.  Help to off the shelf drives add uncertainty to the reliability of the table.   I would never use one of these for primary production so data.  To provide the best protection in this case, I would use only RAID6.   R10 would be down, but may suffer and failed with two failed disks in the mirror of the same value.

  Kind regards

• How to suggest a new symbol of certification: (as OCP *), which includes certified more than professional oracle performance and tuning?

  Hello

  There are several versions Oracle has removed the requirement of performance and tuning in what concerns OCP.

  You can get a separate ECO - Oracle Certified Expert for the performance and tuning.

  However, databases there include performance and tuning in the basic DBA certification.

  I understand there is an OCP (for DBA) and a separate OCÉ (performance and tuning),

  but could it be considered as an additional symbol combining the OCP and OCE (such as OCP * or OCPE or OCP2).

  We could always get and OCP for DBA and a separate ECA for the performance and tuning.

  If there was an an additional symbol, then maybe selftest software would also create reviews of preparation for the performance and tuning.

  Perhaps more people write books on their performance and tuning of certification.

  Maybe Oracle would provide Web seminar Exam Prep for the performance and tuning.

  Thank you Roger

  That hangs high hopes on a couple of letters.  The problem, however, is not perception, but the economy. Traditional publishers must sell a lot of books to make return on investment in the costs of creating a new. Until they beat X-thousand books, they are in the red. STS and transcend do not have publication costs, but they still have to pay someone (probably a very expensive one) to go through the mind-numbing task of creating a bunch of questions / answers that are enough like the real exam to be useful, but different enough to not be do not cheat. They should sell enough copies of the review of the practice of paying for that person, and then more overhead before making a profit.

  The main reason that I was able to create guides to study at the best prices is because they are printed on demand.  I don't have to recover the costs of printing a large number of copies in the hope they will sell. In addition, as I do all of the writing to editing to marketing of myself - it has no salaries to pay someone else. Despite this - I could easily do more initial money by running Oracle contract/work councils for the same number of hours that I put in my books and practice tests. I was called to joke with my wife I could do more by night shifts working underground, asking people if they want fries with that.

  The problem with an author or an editor of creating a book especially for an Oracle performance certification (say 1Z0-064 or 1Z0-117), is that there is so much work involved in this than the creation of a book of generic performance Oracle or Oracle SQL Tuning book, but the very act of this direct to the test severely limits the people who can buy it. Those who study for 1Z0 - 064 could well but a generic performance Oracle 12 c book.  However, people in the market for a book of performance 12 c but * not * intended to take certification 064 are not likely to buy this book even though she 1Z0 - 064 on the lid.

  There are not many hug of people with the knowledge and the ability to create these materials. This relatively small pool, it is there not much with the desire to do. This further reduced pool, there not much time for her - or at least of time they are willing to take more lucrative projects requiring their skills.

• Big client - vCenter 5.5 response time of the customer Web U1c / questions of Performance and Navigation

  So we're all aware of the issues with vCenter 5.5U1 WebClient and how we are forced to use it to make use of all the features of the v10, vDS 5.5 vHardware (config switch changes the synchronization problems if an emergency change is done on c# client vDS) VSAN only available via the web client, flash, sluggish to questions do not respond the questions and the list goes with the presentation of the menus and hard to navigate, issues SSO (always after 5.5 upgrades)

  So @ VMware vCenter Architecture Team is going to make an effort to hear and give due to the much needed performance improvements and improvements to the user interface before adding more features and SSO type services which majority of clients don't use not and not force it's customers continue to loose faith its vCenter product?

  Looking for answers with options to remove vCenter 5.5 U1c installation as well as a promise to answer to these in vCenter 6.0 version!

  Here is your answer. First of all, to use Chrome as your browser, then you need to go with at least 4vCPU * 32 GB of RAM & adjust the segment size of java for SSO, Tomcat, (TC) Management Server, inventory server and profile based storage to "refine" vCenter device with DB Oracle embedded or external memory. I did, and performance gains went 10 X. This includes the vSAN enabled running clusters. My recommendation that works very well based on design documents:

  vCenter Server inventory	VMware VirtualCenter Management Webservices (tc Server)	The inventory service	(Sps) profile-based storage service
  Large (more than 400 guests or 4000 VMS) stock	4 GB	12 GB	4 GB

• Save the number of the Virtual Machine: expand the size of the virtual disk of Guest OS affect the physical disk on the host operating system files?

  People,

  Hello. I use 3 Player VM and Guest OS Windows Server 2003. The host OS is Windows 7. I need to increase the size of the VM disk, so who can install several systems in the guest OS. If something bad happens during the expansion of the size of the virtual disk, the guest operating system and its Applications will not work. Thus, before expanding the size of the virtual disk, I need to back up the virtual machine hard disk external.

  I have check the disk hard host operating system Windows 7, the path is C:\VirtualMachine\WindowsServer2003\... When I get to the top of the virtual machine on the external hard drive, simply select the 'VirtualMachine' folder and save automatically. I have 3 questions as follows:

  First of all, if something bad happens during the expansion of the size of the virtual disk, the guest operating system and its Applications do not work. Can I just delete the folder 'VirtualMachine' in the host operating system?

  Secondly, the problem of the first question does not affect files in the physical hard disk to host operating system?

  Third, if something wrong happens during expand the size of the virtual disk of OS guest, I simply delete the folder 'VirtualMachine' in the host operating system and load the original 'VirtualMachine' from the external hard drive in the host operating system. Works correctly as long as one is the Virtual Machine before Stude the virtual disk size?

  Thank you.

  Yes.

  That's right, as long as you have not added and other virtual disks of different folders on the host of the virtual machine, you can probably did not.

  After developing the size of the virtual disk, you must also change the size of the partition in the guest operating system.

• Moving virtual center SQL DB - consequences?

  Yes, they will be fine.  Although if you are creating a new database, they might not show as recorded in your inventory.  You'll just have to browse the datastore (s) and add them to the inventory.

• You can edit vmx file while the virtual machine is running? And is it safe?

  You can edit vmx file while the virtual machine is running? And is it safe?

  Hello

  Moved to the forum of the Virtual Machine and the guest operating system.

  If you edit the VMX while the virtual machine is powered on change is not levied until the power off then power on (not reboot) and there is a good chance that the change will be deleted when turn you off the system. So it is not safe to do so.

• Daily series VS Performance and entertainment?

  HP has desktop computers in the "Everyday Computing" and "Performance and Enterment" series.

  I adapted a desktop computer in both series.  For the series of performance and Entertainment Office, you get more choice of components.

  However, the components that I need are available for both series.

  In addition, desktop computers has the same motherboard.

  If desktop computers have been adapted with the same components, wouldn't they have the same performance?

  I understand what you ask because I did the same thing and had the same questions.  The answer is Yes.

  But there are other differences between the two lines, in addition to the customizable options of cpu, ram, disk hard size and chip/card graphic.  Click the tab of the sheet and you'll see different chassis sizes, sizes of power, a different number of slots, etc.

  The series 'Performance and play' has a more robust architecture and is easier to add updates in the future, as the media platforms continue to evolve.  Also gives you a little more space inside to work with.

  I hope this helps.

  SATA driver problem.

  Please help me...!

  Answer me

  Hello

  Windows XP needs a SATA driver if you want to install on the laptop with SATA HDD controller.
  Driver SATA can be found in the Intel Storage Manager.

  I advise to use nLite program to include a SATA driver in the new Windows XP CD, then boot from the XP CD created new.
  You will find details of the nLite:

  With regard to the problem of Server SQL;
  You may be able to install in Windows XP. There may be a compatibility problem between Vista and SQL Server software

• Profile of Performance and memory

  Hi, guys

  Trying to analysis the data of my profile to the profile of Performance and memory.

  When I check the data for VI times, I found there are same screws with different time of VI, whatever that means

  Why I cela it is because I will add model pulse for my VI, so I need to know the relationship between my all instruments and time, I'm on the right track

  Thank you

  It seems that the calendar had a resolution of 15.6 ms, which I think is common on some flavors of the Windows operating system.  Note that the average time on some of these screws is equal to zero.  This suggessts that time for many tracks 1878, was probably recorded as zero and some were 15.6 ms.

  It's one of the limitations of the Profiler.

• How to send the SQL for SQL Server statement and return data without using database connectivity Kit?

  Hi, I tried to figure out how to extract data from my SQL Server databases and reading messages and to do some tests with examples, I can get data connection type in my SQL server, but so far nothing helps.  Is it possible to get data from a SQL Server database without using the database connectivity Toolkit?  and if so, how?  are there whitepapers and/or examples of this?  So far, I can't find something that works.  Thank you.

  Jesse - what is your reason for not using the database connectivity Toolkit? It is by far the best way to recover the data.
