• How views can improve performance

  Hello

  Can someone explain to me how the views can improve the performance

  When DMLoperations perform through VIEW rather than perform DML operations by table.

  Thank you and best regards,

  Hi Ibrahim.

  A view is not much more than a macro which is developed by the SQL engine when running. Generally speaking, views will not improve performance.

  You can take the help of INDEXED VIEWS to improve performance. Then, views have clustered index assigned and, when they do, they will store the temporary results that can speed up queries that result. These views can speed up and simplify the application design.

  What is the INDEXED VIEWS?

• ReceiverThreads JMS connector in 10.1.3.3 layout to improve performance?

  Gurus,
  
  I use nonBlockingInvoke = true property in bpel.xml to spawn a thread for each parallel flow activity.
  
  However, the definition of this property I found success in performance. I suspect that the parameter of ReceiverThreads to be the question JMS connector. If ReceiverThreads more could hear in the queue, you can improve performance. (Page 47 of the 10.1.3.1. Performance Document).
  
  But I'm not able to locate this property in orion-ejb - jar.Xml. This property holds a different file or this property needs to be added (please can you provide the exact code)?
  
  Thanks a ton!
  SP

  You can find the documentation of ReceiverThreads here:
  http://download.Oracle.com/docs/CD/B32110_01/Web.1013/b28958/JMS.htm
  (Table 4 - 11).
  There is above the table of examples that show how to add a property.
  (A property can be added to orion-ejb-jar. XML or ejb - jar. Good XML if you set the property via a file .xml orion-ejb - jar.xml is recommended because it is a specific OC4J parameter).

  Alternatively, you can set via the annotation. See here:

• How can I improve performance Adobe CS5?

  I got a trial of Adobe Creative Suite 5 on a PC at work and so far it's ok, but it's really trolling. The PC currently has an Intel Core 2 Quad Q9400 2.66 GHz, 4 GB of Ram DDR2, 160 GB HDD, and an integrated Intel graphics chip.

  Add a dedicated graphics card will improve performance of CS5? I read on the forums that Mac users use a 2nd hard drive as a "scratch disk" for the likes of photoshop which improves performance but do not know how to implement that.

  Any ideas would be great.

  The integrated graphics may well take all system RAM. In addition, you enter your operating system but I recommend Win 7 64 bit with a boat load of RAM.

  Fast hard drives with a drive of dedicated work will help, too.

• How can I perform a clean installation of Mac OS x for my iMAC, retina 5K late 2014 with drive of Fusion with the intact Recovery HD partition?

  How can I perform a clean installation of Mac OS x for my iMAC, retina 5K late 2014 with drive of Fusion with the intact Recovery HD partition?

  Pure how to install OSX on a Fusion drive and keep the recovery disc function

  These instructions assume that your iMAC partitions or file systems has been damaged and you want to restore to the way most efficiency with fusion drive and the recovery partition, similar to what was built in the factory.

  These instructions work for the iMAC, retina 5K end 2014 version comes with OSX Yosemite. The scores of major drive of the 128 G SSD and 3 TB of HARD drive has been configured as a logical drive (merger by car).

  WARNING: These instructions here are shared for interest only. Readers to take their own risk by following these instructions. The author is not responsible for any damage caused by following these instructions.

  This is the target disk partitions, and the configuration that we want to achieve.

  Disk0 is the 128 GB SSD - solid state drive and holds the start of the partition (disk0s3)

  Disk1 is the 3.0 to HDD - mechanical transmission and holds the Recovery HD partition.

  There are two EFI partitions to partition table GUID on both hard drives (disk0s1, disk1s1).

  Disk space remaining (partition disk0s2 and disk1s2) are used to create the disc of Fusion 3.1 to named "Macintosh HD".

  / dev/disk0 (internal, physical):

  #: NAME SIZE TYPE IDENTIFIER

  0: GUID_partition_scheme * GB 121,3 disk0

  1: disk0s1 EFI EFI 209.7 MB

  2: Apple_CoreStorage GB LVG 121.0 disk0s2

  3: disk0s3 Apple_Boot Boot OS X 134,2 MB

  Fusion unencrypted drive

  Here's how we do it.

  • A. clean reinstallation of Mac OS x.
  • 1. make sure that you back up all your data on the hard drive using Time Machine or other means. The following procedure will delete all data.
  • 2. create the OSX install USB, insert it to the MAC workstation.
  • 3. given that us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 4. in the menu at the top of the screen, select disk utilities.
  • 5. turn highlighted the volume of disk Fusion called "Macintosh HD." Click clear to clean.
  • 6. If his success, then go ahead to install OSX new to that partition, as usual.
  • 7. otherwise, if it does not, that means fusion drive has been damaged.
  • 8 follow the instructions below to fix it.
  • . B. Split disc Fusion in the physical hard disks
  • 1. Since us will be operated on the internal drive of the Mac trunk, assumes that we already have boot up OSX install USB drive (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3. on the screen of the terminal type:
  • Cs diskutil list.
  • You will see something similar to the screen below.
  • 4 copy the long string after Logical Volume and replace the UUID with it in the following command to delete the logical volume of the disc fusion (aka coreStorage of logical volume):
  • diskutil deletevolume cs UUID
  • For example:
  • diskutil deletevolume E59B5A99-F8C1-461A-AE54-6EC11B095161 cs
  • 5 copy the long string after the logical volume group and replace the UUID with it in the following command to remove the drive (aka coreStorage) fusion:
  • diskutil cs remove UUID
  • p. ex. diskutil cs remove E03B3F30-6A1B-4DCD-9E14-5E927BC3F5DC
  • 6. at this stage, the fusion drive has been deleted, and hardsisk SSD and mechanical hard drive will be reappear in diskutil or separate records.
  • 7. If step 5 or 6 takes more than 30 minutes to complete, this means that the fusion drive has been corrupted. You can follow the commands below to clear the table to partition the hard way. First command clears the SSD drive, second command erases the HARD drive.
  • The command does not return a response, after 1 minute, press Ctrl + Z to complete orders. 1 minute is enough data to code and erase the partition table on the disk.
  • cat/etc/random >/dev/disk0
  • cat/etc/random >/dev/disk1
  • . C install a new copy of Mac OS x for the hard drive HDD and tested this disk partition hard recovery work.
  • 1. go on diskutil to create a partition called Macintosh HD HDD hard drive using all the space there.
  • 2 do the same with the mechanical hard drive.
  • 3. follow the usual procedure to boot from the installation of OSX USB and install a new copy of Mac OS x hard disk SSD.
  • 4. This will create the correct priming of the partitions, recovery hard drive partitions and PSX partitions hard disk HDD.
  • 5. once the installation is complete, test if OSX may start successfully, but no need to go through the initial MAC OS x didn't put in place that we're going to waste this and do the installation again later.
  • 6. we must now test if the recovery hard drive partition works.
  • 7. reboot for hard drive recovery (see X - by pressing command and R at the same time during boot right after that you hear sound start and release only a few seconds after you see the apple logo and the progress bar for loading...)
  • 8. it is important to test and make sure that the partition of hard drive recovery.
  • D. recreate the fusion drive
  • 1 since us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3
  . on the screen of the terminal type:
• diskutil list.
• You should find that we have a list of disk group hard physical volume only, no logic here still.
• 4. you will see something similar to the screen below.
• 5. search for the largest partition on the SSD hard drive, which should be close to the maximum size of HDD to the SSD (121 G, for example) and mark the name of the device, this will usually be something like/dev/disk0s2
• 6. search the largest disk partition mechanical forming fusion with the SSD hard drive. This should be close to the maximum size of the mechanical hard drive (for example 3 TB) hard disk and mark the name of the device, this will usually be something like/dev/disk1s2
• 7
. Now let's create the merger in car (group alias logical volume) in the Terminal, type: diskutil cs create nom_lecteur driveIDs
• The number of the driveIDs is unlimited, it may be a number of discs, or a number of disk partitions. Always put the faster discs first, for example for our SSD disk0s2
• For example:
• diskutil cs create fusiondrive disk0s2 disk1s2
• diskutil - the version of disk utility command line.
  cs - This calls for Core Storage, which is necessary for the merger.
  create - creates a basic storage group.
  nom_lecteur - is the name of the drive and how you want that he
• appear in the disk utility (not the Finder - that comes later). You can call it what you like; in our example, we named our Fusion table "Fusion".

driveIDs - Here is the Player IDs of the readers you want as part of your Fusion table, separated by a space. In our example, they are 'disk0' and 'disk1', but it may be different in your configuration.
• It is important that the faster hard drive appears first in the command, which in our case the disk0s2 (a partition in the SSD). In this way, drive fusion will use this disk as primary and the cache. The second disc in the command, in this case disk1s2 (a partition on the HARD disk). The secondary disk (HARD drive) is used to store less frequently used files.  Otherwise, the fusion drive performance will be worse that it is designed for.
• 8. you will see something like below appear on the screen:
• Creation Volume logical storage of kernel
• Move isk0s2 storage of carrots
• Disk1s2 of switching for the storage of carrots
• Waiting for logical volume group appear
• Discovered the new group of logical volumes 'DBFEB690-107B-4EA6-905B-2971D10F5B53 '.
• Store LVG UUID: DBFEB690-107B-4EA6-905B-2971D10F5B53
• Finished CoreStorage operation
• 9 copy to the bottom of the string after "Discovering new Volume Logic Group" using the command + C
• 10. next, create the partition of the merger (alias logical volume) drive named "Macintosh HD".
• In the Terminal, type: diskutil createVolume groupString jhfs cs + size volumeName
• For example:
• Diskutil createVolume DBFEB690-107B-4EA6-905B-2971D10F5B53 jhfs cs + 'Macintosh HD' 100%
• diskutil - once again, this is the version of disk utility command line.
• cs - called the basic storage functions, which are necessary for this arrangement.
• createVolume - this is the command to create the storage area real for the reader who is represented by an icon on your desktop.
• groupstring - this is the long alphanumeric string you copied in the previous step. It identifies the table you created such as getting a volume placed on it.
• jhfs + -the format of the disc. It is Apple (journaled) extended Format, which is recommended for drives with an operating system installed on it.
• VolumeName - the actual name of the volume, how it should appear under the icon. If there is a space in the name, you must put the full name in quotes ("name") or put a slash before the (name Drive\) space. In our example, we made these, naming our volume "Macintosh HD".
• size : this is the size of the volume. In our example, we had a 1.1 TB drive. We used '1100g' to describe what 1100 GB (1.1 TB to base 10). Otherwise, we could have also used 1.1 T or even 100% as a size.
• 11. go to diskutil to verify that you can see this new partition on the list.
• 12. test by erasing all the data from it.
• 13. then you can go ahead to start on the USB drive to install OSX and install a new copy of Mac OS x on it.
• 14. This will allow you to keep the recovery disk feature.
• X. how Prime to recover partition

• Can anyone tell how I can configure the desktop as the default screen that appears when I connect to Win 8?

  Original title: Desktop

  Can anyone tell how I can configure the desktop as the default screen that appears when I connect to Win 8 rather than having to go from the first layer redundant 'start-up '.

  In fact, if anyone can tell if there's a free windback to an earlier version of Windows (7) who has not all layers unnecessary and icons, I would be really grateful

  Your best bet is to switch to 8.1, that allows you to boot directly to the desktop, and then use a menu like debut8 to replace the old Start Menu and hide the side of the metro.

  If your computer comes with Win Pro 8, you may be able to demotion, otherwise, you will need to buy 7. Before you buy 7, I would recommend go to the computer manufacturer's website and see if there are any Windows 7 drivers for your computer. You may lose certain functions - sound, network, video full resolution - if there is no driver.

  The first option is easy and allows you to keep the improvements in performance and safety 8.

• Improved performance in vCenter

  Hello all - I hope that the community can help out me with this one.  It is related to the performance of vCenter.

  VirtualCenter arrived at the point where it's VERY slow almost all the time and I cannot understand why.  As examples, in the computers view models, and virtual VC locks up often for anywhere from 20 to 60 seconds, just by selecting one data center to another.  RVTools almost 20 minutes to come.  Also, if I try to install VeeamONE or VeeamBackup, they are slow slow is not usable and sometimes lower VC (so Veeam is not running - I just wanted to give an example).  Finally, if I restart the server (VM) VirtualCenter, it can sit to 'Apply the settings of the computer' for about 20 minutes.

  I support a vSphere environment that consists of the following

  vCenter: 5.0 Update 1 - running on a virtual of Win2k8R2 computer with 8vCPUs and 20 GB of memory

  SQL Server VC: 2008R2 SQL - running on a VM Win2k8R2 with 8vCPUs and 32 GB of memory

  MUV: VM dedicated

  VC Web: VM dedicated

  * The four run VMs on a dedicated Cluster 2 nodes 'management' which consist of two HP DL380p G8s DualProcs & a lot of memory. No other virtual machines running on the host & loans are all practically zero.

  He currently manages 316 ESXi hosts (all 5.0 Update 1) and about 6000 virtual machines.  When VC was installed, I chose the "Large" scale that we will add more than about 200 guests & about 1000 VMs more next year.  The use of the Cisco Nexus1000v ESXi hosts (excluding the 2 cluster nodes mgmt - those that are on the standard vswitches).

  The hosts and virtual machines are in data centers about 20 & 30 clusters, physically dispersed across the country (US).

  Any thoughts on how to make it better?

  Thanks in advance!

  From there, should I run the script to purge old data from the other KB, or should I expect to see improved performance immediately?

  Yes, but... To do the purge your vCenter Server Service must be stopped.  Always better this offline.  We usually do maintenance on our vCenter DB about each quarter.

  Hi all

  Can someone explain, I have a 2 phisycal Server sunfire x 4600 m2 with 4 phisycal 2.8 Ghz processor and 16 GB of memory each. I configured the cluster (HA & DRS) (fully automatic). My doubt is is - this problem with one of the host, he's moving the virtual machine host to another host? If this happens, how is the performance? is it ok have each host 8 virtual machine or I want to reduce the virtual machine to improve performance?   Please help me I have suffered.

  If both of your hosts are running at 70% memory usage you can consider for reasons HA.
