  Hi friends,
  I have a question about services and proxy services business IE I need to find the time it takes to call an operation on multipoint business of proxy service, how can I do in oracle service bus (OSB)? You can help quickly

  If your question is only about the performance analysis,
  try to activate the 'monitoring' on the 'operational' of the Service Proxy Service/Company tab.
  For the Proxy Services, if you activate at the level of the 'Action' you get a lot of information about each individual action in a power of attorney.

• A question about clusters

  Hello
  
  I have a question about the single table hash clusters. How are these paintings in a position to provide better performance? Any block can contain data from a single table, and here was the only cluster table will also create blocks with data from a table. So how or why is it more effective? I am not unclear on the concept plan and will be grateful for the info.

  The benefit is provided
  (1) exercise you some control over the way in which the data are filled in the table
  2) most of your questions is a 'SELECT col1, col2,... '. "Col WHERE = "
  (3) the number of values unique 'col' is fairly constant
  The common approach in the situation described above is to create an index on 'col' so that applications may perform better.
  But even with the indexes in place, oracle will need to access the blocks of two segments, index and table, in order to process the requests (of the type described in step (2) above).
  When you create the table in a hash TABLE UNIQUE cluster, you can get the grouping of the data in the table itself, without the need of an index. Oracle will have access to the only segment (cluster) blocks to process requests (of the type described in step (2) above).
  The result is much less number of consistent gets for queries of the type described in step (2) above, resulting in better use of the buffer cache, which improves performance.
  I hope this helps.

• Windows 7 starts questions about mac and office 2010 following an installation

  It's a long cut as short as vent. I've been miss sold a record of upgrade of windows 8 full disk-shaped, with norton and office 2010. My goal of creating windows on my mac for a course I'm taking. After that know I need windows 7, I bought it online. I created a partition of 80g on my mac charge windows 7, then norton. Until I loaded the office that I was invited to perform the update from apple in the windows software 7. Note before I installed norton, I load boot camp mac utilities according to the instructions. So, followed by all as should be. The prompt update from apple was quick time, iTunes and airport, I checked all and then updated. Then I loaded office 2010 and obtained throughout the process from the Microsoft site. On the last part of the installation, the installation failed due to a mistake of hanging iTunes. I tried again and again, I fixed the update to iTunes to add and remove the section of windows. Then, I got different errors. I decided to remove the whole score without uninstalling all programs again. When I get to the windows live, that this falls priming. I get various error messages whenever I try to start the process.

• Question about snapshots and virtual machines

  Hi all

  I have a small question about snapshots. I use VMware for about 6 months and I read about snapshots and how they work but still have a question to make sure that I understand how it works and it will work the way I think it works.

  I have a Windows 2003 server, which is a virtual machine. I have an application that uses MSDE database. I want to upgrade the database to MS SQL 2005, but to do this I need to back up the MSDE database, uninstall MSDE, and then install SQL 2005 and move the SQL database. This happens on the same VM.

  What I was thinking if I well Snapshots correctly is to snap turned the virtual machine before doing anything. Then do my upgrade steps and see if everything works. If its all messed up so I should be able to return to my shot and everything should be the way he had. What is the good? One of the main reasons I moved the server VM was because of this upgrade.

  After reading the documentation for the snapshots, it's how I undestood it. Pretty much any change could be reversed with snapshots. I wish just they had put in a few examples in the PDF file. Also it would be the same for all type of grades of the OS? Could I snapshot a Windows 2000 Server, and then "in the upgrade of the square" to Windows 2003? I've cloned a VM to do this but was curious about whether snapshots would be just as easy.

  Thanks for your help.

  That is right.

  Exactly the same thing for the upgrades of the OS.

  Perhaps the most important thing with the snapshots is to keep an eye on them and don't let them sit too long or become too big.  You have described the use cases are very good uses for snapshots.  Just make sure you have a solid plan with a schedule set, so that you can come back or validate changes before the snapshot becomes too large.

  Good luck!

• Question about CR and LF

  Hey guys,.

  Quick question on LF and CR. As you can see I'm LF and CR of writing to a text file and because directly.

  

  However, I don't get the CR at the time where I read it. Why is this? Is it because Windows ignores the CR?

  Thank you

  Hi dora,

  read the Help for the WriteText function.

  There is an option for handling of CR/LF characters and explained mentioned in the "Advanced" section of the article for help!

• Question about removing a HOST and add it again with the other IP management

  Thanks in advance for your help.

  I have an environment with two centers of data/clusters inside my virtual Center 2.5

  One of her consistes of clusters on two ESXi 3.5 licensed nodes. Each of them has 2 VMKernel ports form management. One of them has an IP (A.A.A.1) with any VLAN, the other port is in VLAN111 and IP (B.B.B.1). The other host ESXi has A.A.A.2 and B.B.B.2 IP.

  The other cluster has two 3.5 ESX (not i) and they have a single port/IP managemente (in the VLAN111, which is the same as the other cluster)

  The first cluster appears associated with the virtual center with the No.-VLAN port (IP A.A.A.1 and 2). Is a problem for me because I need to access the first cluster of other machines having no visibility on the A.A.A.x subnet, but it has visibility to the VLAN111. If I connect to the virtual Center, he shows me the IP A.A.A.x but when I try to access them, I can't.

  I would like to do the following WITHOUT affecting the first cluster:

  -Remove each host in my Center Virtual (The VM will continue to work without problem?)

  -Add each host the virtual Center, but this time I'll add the IP VLAN111 (B.B.B.x)

  My question is if these will generate instabilities problems on my dock.

  Thanks in advance

  This process has worked for us when the old VC (2.5) ESX Servers moving again VC (4.0).

  1 undo the HA and DRS configuration on the farm.

  2. unplug all battery ESX servers.

  3 remove all ESX server farm servers.

  4. Add the ESX Server to new cluster in VC (4.0).

  5. configure the HA and DRS on the new farm.

  Used for over 700 ESX servers with zero impact.

• Fibre channel host bus adapters should be removed if not in use?

  We have a Dell Poweredge R720 server that has a Qlogic host an orphan in her bus adapter. The lighting on the HBA flashes yellow, green and orange. I wonder if this orphan adapter could use the system resources and if it should be removed.

  Kimblbob,

  Despite the HBA is not used, it will use resources. Now granted it's a very tiny amount, but he uses them what. When the card is installed, it will draw power, as well as the host server will spend processes in the sending of communications "heartbeat" with the card, it is ready to use it... Thus, while it is a VERY small amount, he uses them.

  I see no problem with you withdraw during a maintenance window.

  Hope this helps to answer your question.

• Question about ESXi and NFS

  Greetings!  I'm hoping to get feedback on the following possible scenerio.

  Computer 1:

  The computer that is running Windows Server 2008.  Large amount of storage available, via dedicated hardware raid or 'software' / raid ICH10.

  Computer 2:

  Computer running ESXi v4 (installed on the local hard drive).  Core2Quad w / 8 GB RAM.  Responsible for about 4-5 virtual machines.  Each virtual computer will be low IO load (DCs environment lab, MySQL server, web server).

  I have three questions:

  1. are there any problems with the use of the space on 1 computer through Windows 2008 NFS to host virtual machines that will run on computer 2.

  2. because I do not use hardware RAID on computer 2, I won't RAID1 for redundancy.  If the hard drive fails, but virtual machines are on a redundant protected NFS share on Computer1, is there loss of data outside the need to reinstall ESXi on a new hard drive?

  3. someone can tell the performance of a 'software' RAID (probably RAID5) NFS share (ICH10, etc.) from the point of view of virtual machines hosting?

  Thanks in advance!

  1. are there any problems with the use of the space on 1 computer through Windows 2008 NFS to host virtual machines that will run on computer 2.

  Although the NFS Windows service is not the most ideal, it will work fine. You want to make sure there is no automated etc. updates and limited storage functions of the machine.

  2. because I do not use hardware RAID on computer 2, I won't RAID1 for redundancy.  If the hard drive fails, but virtual machines are on a redundant protected NFS share on Computer1, is there loss of data outside the need to reinstall ESXi on a new hard drive?

  It would not be otherwise than a hardware failure on any machine. You don't have the risk of data damage whether physical or virtual.

  3. someone can tell the performance of a 'software' RAID (probably RAID5) NFS share (ICH10, etc.) from the point of view of virtual machines hosting?

  Without hardware raid with a caching controller you won't have better disk performance. Controllers setting cached on RAM and will require a battery to protect the cache failure.

• M30-832: Questions about memory and DVD player

  Hi all, new to laptops up to have a few questions! First of all, I have a Satellite M30-832.
  1. He has on the dvd player on the side of the Compact disk with re-writable below image and sign dvd R/RW under. That means it is a DVD burner as well? It does not sem to recognize blank DVDs and I was under the impression that it should be possible to write about them!

  2. can I upgrade the memory with memory DDR - RAM modules or does take a special type? And how to change them!

  Thank you very much

  Hi Richard,

  From what I can find your M30 832 is equipped with a DVD burner so you should be able to burn DVDs (the specification says you can only burn at X 1 speed for DVDs).

  You should be able to update your RAM to a maximum of 2 GB and I recommend you buy a quality mark to avoid any problems. Your user manual should have details on how to change the RAM modules, but generally it will be to remove a panel of access (usually on the bottom of the unit) and then releasing it two clips (one on each side of the RAM modules) plastic spring-loaded and gently raising the output modules.

  Please make sure that you either wear a wristband anti-statuc dirt or this earth you yourself before accessing RAM modules. They are very sensitive to electrostatic.

  You can find suppliers of RAM suitable if you GOOGLE 'M30 832 RAM.

• Question about phone and / or Android 1.5

  I have a question or a statement that needs confirmation. If someone could be good enough to help out I'd appreciate it.

  I am a heavy Texter and text on a daily basis, probably an average of about 250 + texts per day. Also, I noticed and I took County, after about 4 hours of texting the android keyboard and also the swype keyboard, affecting the time key to key response starts to slow down and get slow and ultimitely is unbearable to the text with. Even with the home screen and sliding screens from left to right, and as I said it doesn't happen only after some hours of use of the phone. So, I have to restart the phone and repeat for it keep to become lazy and unbearable to text with. I usually reset every morning or when I wake up. This is nothing compared to my sisters Mytouch, which is in fact older than my phone, it can affect his day at the time and not get done with the delayed touch response. I also noticed that his phone is running Android 1.6.

  Now my concern is, if I'm the only one knows this or is it due to a defective phone. What is the Android obsolete 1.5 that many people are talking about who is performing on the phone in this way.

  Basically, it's because of 3 things.

  1. history - more history, more than it takes to load. (If you wipe all messages and try again, you'll see what I mean)

  2 android 1.5 - don't know what the reason, but even on 1.6 devices SMS language delay is AVERAGE less.

  3 Swype - if you have enabled, it tends trolling more than the default android.

  It is not your phone, it's all phones Cliq/Cliq XT... 1.5 hate text messaging.

  In addition, your phone will work more effectively without a task manager. They are nice to have if you need something CF or to extend the life of the battery (no), it actually takes your phone like some processes that would otherwise, and you also have the risk of frost on the phone all together because some group programs are essential and cause the home screen all recharged after their closure. I would like to refer to this site in order to better explain.

• Question about the collection of NETWORK adapters for vMotion / VM vSwitch

  Hello

  We use vSphere Enterprise Edition 5.1.

  We also create separate vSwitch for management / vMotion and VM.

  Each vSwitch receives 2 network cards connected to the different switch for redundancy.

  We would like to know is necessary to provide the collection of NETWORK adapters for these vSwitches?  Currently, only enable us NIC Teaming for VM vSwitch only.

  Thank you

  VSwitch vMotion, we have 2 assigned NIC (nic2 and nic6) with 10 VLANS.  NIC2 and nic6 are connected to 2 different physical switches.

  Should I choose

  (1) both are active

  (2) both are assets + grouping of NETWORK cards?

  Question - if there is only 1 VLAN, it seems that NIC Teaming is also not very useful unless we use 2 VLAN (Multi-NIC vMotion).  Is this right?

  If you use Multi-NIC vMotion, there is no need to have two different VLANS, all you need is depending on configuration

  on your vMotion switch, please create two vmkernel port for vMotion with the same VLAN ID, but the grouping of NETWORK cards as below

  vMotion_1 - VLAN ID: 10

  Grouping of NETWORK cards

  vmnic2 - active

  vmnic6 - watch

  vMotion_2 - VLAN ID: 10

  vmnic6 - active

  vmnic2 - watch

• question about SQL and VMDK places

  Hello world. Im kinda new here so please be gentle

  I'm confused on the locations of the files for sql.

  At this moment I have 1 with 3 vmdk files sql server executes a muscular 100 GB sql database.

  My disks are as follows

  1 OPERATING SYSTEM

  2 DB

  3 newspapers

  They are all thick and they are all stored with the virtual machine in the virtual machine configuration.

  It lies in a cluster HA/DRS and we use them both.

  The question boils down to performance.

  If my VM is stored on DATASTORE_A and the VM folder on this data store has all the VMDK files in it, it would be safe to say that they are all on the same disk as much as vsphere is concerned.

  Now to get best performance, I want to separate my VMDK files to separate data (with faster operation) warehouses to avoid conflicts of drive on my current data store. What is the right way to go about this?

  How separate you your VMDK to other data warehouses, and enjoy other performance data store? WE do not use DTS at all so im sure it although we use HA/DRS in our group... and yet, I don't think that it is important in this case... just more of an FYI.

  What do you do to get your SQL servers to run in vmware?

  Seems like a basic question.

  The answer seems easy. Separate disks so that they do not fight.

  'S virtually done it with VMDK but the data store underlying is 1 speed and they all exist on this subject, so... How to separate them at that level for best performance?

  Also... once I keep them separated, how can I keep my sanity by knowing my VMDK are not with the virtual machine? This kind of made a mess . Of course the performance takes a front seat for my mental health.

  Thank you all

  1. If I sVmotion my other vmdk files via the advanced options of one in another data store, it will create the files folder structure based on my VM name and place the vmdk inside?  (I guess I could just test it and see).

  Yes, the VM configuration file (.) VMX) will be modified to point to the new location of the virtual disk. You can use the virtual machine property editor to check for this, once the Storage vMotion.

  2. with regard to the disk controller, I assume you mean a virtual controller by VMDK in the vmx / correct the settings of the virtual machine and not a phyical on the hardware controller? (IM pretty sure I know the answer here but I just want to be clear).

  Yes, the virtual controller is correct.

  If so, what type of controller? LSI Logic or it would benefit all a paravirtual adapter?

  As long as your operating system is supported, go with the PVSCSI every time - especially for newspapers and the controller file data.
