What exactly does 'Open Filer' do ?

DB version: Oracle 11gR2
I have installed and maintained Oracle RAC in the Real World systems (Solaris and AIX). Here the Nodes are connected to shared storage via HBA cards. I've seen Blogs, articles of people using VM Ware, Oracle Virtual box creating RAC in their Desktops/Laptops. Creating several virtual machines (Solaris or Linux) might be easy.
But how can they emulate a shared storage in Hard drive which is essentially used by the Windows Os (on top of which VM is installed) ie. Every single block in Laptop's HardDrive which openfiler uses is actually Windows OS formatted. Right? In layman's terms, what does open filer do in this Hard Drive which is actually Windows NT formatted? Can Windows reclaim the space in the Laptop's Hard Drive which Open filer was using?

I would like my RAC nodes(VM machines created using VM ware Workstation) to run on Solaris 10 (x86).
From the above descrption , i think Openfiler is a Linux based thing. Can a Linux based openfiler work with Solaris Machines?
In short, will the below mentioned config work?
Hardware                 : A Lenovo Laptop with 8GB RAM
Host OS                  : Windos xp (or Windows 7)
Virtualisations software : VM workstation
Guest OS                 : 2 Nodes of Solaris 10 (x86)
Network Storage Server   : Openfiler OS If i want Solaris based Virtual RAC nodes, what changes should I make to the configuration chart shown above ?Hi,
Openfiler has its own OS which is linux.
Your laptop 8GB should be enough to create 2 nodes RAC + 1 node openfiler
What you need to prepare is 3 VMs, 2 for Solaris Oracle RAC and 1 for openfiler
Hope it's clear
Cheers

  • Reducing file size #1...what exactly does file, reduce file size do?

    Questions on reducing a pages to pdf file size…I will post each question seperatly.
    1) I was surprised to see page reduce file size take it from 50 megs to 20 megs…when I looked at a large jpeg file, its size went form 230k to 70k, but the entire image (not just the visible part after the mask) was there (I was hoping it would crop to the mask).
    I am curious, what exactly is reduce file size doing?
    Is it applying a quartz filter that I can control through colorsync (I think not)?
    Thanks, bob

    You will need to test the results, but I suspect it is definitely lowering the resoltion to either screen resolution (72dpi) or double (150dpi) and upping the compression of the .jpegs.
    In contrast to the Quartz filters, the results from file reduction in Pages is disappointing with a hefty loss of quality for not so much file reduction.
    I would work with known distiller settings in Acrobat Pro for a better result.

  • What exactly does Restore do?

    Forgive me if this has been covered before, but I did search and didn't find my specific answers.
    I synced my bookmarks with my Safari browser on my PC. All is good, except that the sync also copied the default bookmark folders "bookmark bar" and "bookmarks", which are both empty and redundant on my Touch. They are listed 2nd and 3rd on the Touch bookmarks list, taking up valuable space! But, since they're default folders, I can not delete them, just like the "History" folder on the Touch.
    Anyway, I've read that the only way to remove them is to restore my iPod, and never sync bookmarks from Safari again. (IMHO it seems completely crazy that syncing from one Safari to another would be so problematic!)
    So, what exactly does Restore do? I know it resets the ipod to factory settings, but what happens to all my bookmarks and webclippings? Is there anyway to back those up and edit my bookmarks manually to remove the two default folders?? Because if not, it seems that this wouldn't be a fix at all, instead just a big ol pain in the arse. This is a very annoying bug and I hope it is fixed in the next update. :/
    Any help is very appreciated!

    Assuming you're using Windows (going by your system specs)...if you have bookmarks you need to preserve only for the touch, export all your current Internet Explorer (IE) bookmarks/favorites to a file and back that up. Then delete ALL bookmarks in IE & sync your bookmarks only using iTunes (IE has to be open for the bookmark sync to work properly). Your bookmarks will sync with IE and only the ones that were on your touch should be in your current IE bookmarks. Now export those bookmarks to a different file. When you want to restore the touch and it's bookmarks, sync the touch and select the option to over-write/replace the bookmarks on the touch. To get your Windows IE bookmarks back, restore from the first backup file you made. Note that the sort order after importing the bookmarks back into IE will be alphabetical rather than by when the bookmark was added. I don't think there's any getting around that.
    As far as deleting the default folders you're looking to get rid of, I don't believe that it's currently possible.

  • Apple_Boot Recovery HD partition - what exactly does it do?

    On a new MacBook Air (Mid 2011) there is a partiton on the internal solid state drive that shows up (you can see it by using Terminal, then type "diskutil list" at the prompt) as Apple_Boot Recovery HD  650.0 MB   disk0s3.
    My question is what exactly does this partition provide?  Is the Internet still required to accomplish a "Reinstall Mac OS X"?
    Does the partition just provide a quick way to reach the Mac OS X Utilities pane (see below) when restarting your computer while holding down the Command and R keys?
    If the partition is not on a MacBook Air (Mid 2011) do you reach exactly the same functionality when you are required to download the Mac OS X Utilities pane from the Internet?
    Once at the Mac OS X Utilities pane, would you be required to use the Internet to accomplish a "Reinstall Mac OS X" even with the presence of the the Apple_Boot Recovery HD partition?

    2. You can boot from any Recovery HD regardless of its location provided it's connected. For example you can use the Lion Recovery Disk Assistant -  OS X Lion: About Lion Recovery Disk Assistant - to put a Recovery HD volume onto a small USB flash drive with at least 2 GBs of space. You can install Lion onto a 16 GB USB flash drive in which case the installer will include a Recovery HD partition.
    3. If you boot from the Recovery HD then the reinstallation is by Internet. If you have your own bootable USB Lion flash drive, then the reinstallation will take place from the flash drive. Here's how the flash drive is made:
    Make Your Own Lion Installer
    1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing Lion.
    2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
    Open Disk Utility in your Utilities folder.
    After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
    4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
    Open Disk Utility.
    Select the USB flash drive from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
    Drag the InstallESD.dmg disc image file into the Source entry field.
    Double-check you got it right, then click on the Restore button.
    When the clone is completed you have a fully bootable Lion installer that  you can use without having to re-download Lion.

  • So what exactly does limited to "one app" mean with a Pro account and the new prices?

    So it seems Pro has dropped in price but it is now limited to "one App".
    So what exactly does that "one App" mean?
    Only one tablet version or one phone version for a certain title?
    Or you can have a tablet & phone version including android & iOS for that one title?

    Changes to Adobe Digital Publishing Suite, Professional Edition
    Effective immediately, all customers who newly purchase or renew Digital Publishing Suite (DPS), Professional Edition, will be able to publish only one app per license of DPS Professional Edition.
    Under this policy change, Professional Edition customers can publish an unlimited number of issues (.folio files) to a single app and distribute those issues based on purchased fulfillment bundles.
    An app created with a single license of DPS Professional Edition can be distributed to any or all of the marketplaces that DPS supports, including the Apple App Store (and Newsstand), Google Play, Amazon Appstore, and the Windows Store.
    In conjunction with this policy change, Adobe is reducing the price of a Professional Edition license to $4,800 USD annually (€3,600/¥480,000) or to $400 per month (€300/¥40,000) and will include 1,000 fulfillments annually. The number of fulfillments included with a monthly subscription remain unchanged.
    This policy does not apply to test or demo apps published using Professional Edition. The one-app-per-license policy applies only to an app published to a supported marketplace(s).
    If you are an agency, upon your renewal or purchase of Professional Edition, you can create only one app per Professional Edition license. If you have multiple clients for whom you are creating apps, either you as the agency or your client must purchase a Professional Edition license for each app published to a supported marketplace(s).

These include app customization, integration with back-end business systems, in-app marketing tools, targeted content based on user entitlement, and the ability to publish apps privately.

  • What exactly does the Radio Beacon Indicate

    I have seen cases where the Radio Beacon is black and when it is gray. When it's black you may or may not be able to go through the wireless router to the modem and then to the internet. When it is gray, you cannot really do anything except be in a local mode. However there are instances when the Radio Beacon is black, rather than gray, and you still cannot access the internet. So, what exactly does the activated Radio Beacon Indicate, i.e., that the wireless network is working and the modem is down, or something else entirely ?

    Assuming you're referring to the Airport icon in the menu bar, 'clear/empty' means Airport is turned off, gray bars means Airport is on but not connected to a network, and black bars means Airport is on and connected to a network. Other possible icon states are solid gray with a little computer inset, meaning you're connected to a computer-to-computer created on the Mac, and gray bars with an exclamation point (10.6 only), meaning connected to a network but not authenticated (e.g. wrong password for an 801.2X corporate/university network).
    To your question, it's perfectly possible to be successfully connected to a network (black icon) and unable to access the internet. Situations like that would include the network requiring a proxy server, for which you haven't set up the details on in Network Preferences, or you're connected to an open network that requires you to enter information or agree to terms (e.g. a hotel network, where you need to put in your room number and agree to the charges before you can connect to the internet).

  • What exactly does the Work Offline option do in a shared review hosted on an internal server?

    Hi,
    What exactly does the Work Offline option do in a shared review hosted on an internal server?
    I *think* it simply disconnects you from the review server. I'm not sure why one would want to do this.
    I'm trying to recommend an offline workflow for reviewers who may not be able to access a shared review hosted on our internal server (for example, while traveling). These reviewers would like to be able to comment on an offline version of the review PDF and then publish their comments when they can again connect to the Internet/internal server.
    It doesn't seem like "Work Offline"  is the right fit for this scenario. Instead, should reviewers save a local copy to their hard drive, comment on it, and then, when reconnected to the Internet, open the local copy, click Reconnect to Server, and then click Publish Comments?

    Thanks, Dave. So for my hypothetical traveling reviewer, it would be reasonable to suggest the following steps for an offline workflow?
    1. Connect to the shared review.
    2. Choose Work Offline from the Server Status menu.
    3. Close and save the review PDF locally.
    4. Comment while traveling.
    5. When back in the office, open the local copy of the review PDF.
    6. Click Reconnect to Server.
    7. Click Publish Comments.

  • Consolidate Masters - what exactly does this do?

    Hi all
    I am a relativity new aperture user. every time i import images from my camera, they have the little arrow in the bottom corner to show they are referenced files.
    I can fix this by clicking file>consolidate masters and choose to move or copy them.
    Forgive the basic-ness of this question, but what exactly does this do? And why can't i import them so they are not referenced files?
    thanks again for your help

    I suggest you read the manual for this sort of questions, but anyway, here's a quick answer:
    -consolidate masters moves or copies your images to somewhere withing your library, making them managed instead of referenced.
    -the import dialog, when you connect a card has the option to copy the files to anywhere on your disk, to pictures or to the library (making them managed, and thus not showing the little arrow).
    For the advantages and disadvantages of either, check this forum or again, the manual.

  • What exactly does the following do?

    i understand what this does.

    return (password == null ? "" : password);

    got it thanks.
    is the reason for this to prevent the javabean getter
    from sending a null to a jsp file?
    for example, if the setter is not called before the
    getter, the value is null and the jsp won't like
    this.
    could you also initialize the properties of the bean
    to ""?That sounds like a reasonable explanation. Depending on the implementation, initializing to "" might work fine or it might have unintended consequences if there's anywhere that a null and an empty string are interpreted differently.

  • What exactly does "rejuvenate my system" do??

    have never run it, but didn't it to change any settings, etc... What exactly does it do and to what files/programs?? Thanks for the info

    untmom2003,
    Description of Rejuvenation copied from the Rescue & Recovery Help window:  
    Rejuvenating your system
    When you select to rejuvenate your system, the Rescue and Recovery(TM) program optimizes system performance by completing the following actions:
    Performs a new incremental backup of your system. This backs up all new or changed files so that all current files are saved in a backup.
    Defragments your hard drive and backup files. This maximizes the performance of your hard drive and backups so that all your data is stored in the same place on your hard disk. This enables your data to be located and displayed more quickly.
    Restores your operating system and application files from a backup of your choice. This enables you to choose which backup to use to restore your computer. You might want to choose a particular backup that you know to be free of viruses, adware or spyware. Or, if you are having serious problems with your operating system or applications, you might choose to restore files that you backed up before you started having problems.
    Restores you current settings and some personal data from the registry. This enables your computer to retain the features that you had previously set up.
    The rejuvenation process maintains your current settings and data while helping to eliminate viruses, adware and spyware. Applications installed or uninstalled after the selected backup was created might need to be installed again to function correctly. This operation might take some time.  

  • "Check Network Connection​" - What Exactly Does the TV Check?

    Hi everyone
    May I please ask, what exactly does the TV check when I choose "check network connection"?
    In other words, when I click the "check network connection", what IP address / servers and ports does it communicate to? What checks does it do?
    Because my TV cannot establish a network connection via settings, but the browser works perfectly well,
    I would like to carry out the same checks of "check network connection" on my PC.
    Then, if failed also on my PC, I would turn to my ISP with the results, as I believe it is the one to fault.

  • HT4859 when you go to do this it say that your iPod or whichever device will no longer be backed up to the computer it is currently backed up to, what exactly does that mean? Will i not be able to sync my iPod from that computer?

    when you go to do this it say that your iPod or whichever device will no longer be backed up to the computer it is currently backed up to, what exactly does that mean? Will i not be able to sync my iPod from that computer? Please help me and answer either or both question detailed thanks

    Normally when you sync your device it is automatically backed up to your computer as the first step in the sync process.  When you choose to start backing up your device to iCloud, iTunes stops automatically backing it up on your computer when you sync.  That's what the message is telling your; that you are now backing up to iCloud and not to your computer each time you sync.  You can still manually back up to your computer any time you want by going to the Summary tab and clicking on Back Up Now under Manually Back Up and Restore.
    You can still sync your device as you did before, it just will no longer back up automatically when you do.

  • What exactly does the AppleCare cover for MacBook Pro with Retina Display?

    I purchased the extended protection plan for my MacBook Pro with Retina Display 15" and my question is what exactly does it cover in what kind of situations (i.e. viruses, damaged ports, damaged charger, etc.)? I want to be able to take full advantage of the protection plan since it was a pretty big whole in my wallet.

    AppleCare covers all the problems you have with your MacBook Pro with Retina display and the peripherals which came with it (your charger) if you have a hardware problem that you didn't cause. For example, after 2 or 3 years and 1000 charges, OS X says that your battery has to be replaced: in this case, you have to pay for the battery, because batteries have got a lifetime, and Unibody Macs batteries have got an average lifetime of about 1000 charges.
    However, if the RAM gets damaged and you haven't done anything to cause it, you will get your computer repaired or replaced for free. AppleCare in a MacBook Pro with Retina display is very important, because near all the parts are soldered into the logic board and repairs are expensive

  • My iPhone 4s was stolen this weekend and I did the Remote Lock.  What exactly does that do?  Also, if i do the Remote Wipe will that erase all of my data and impede anyone from ever using the phone?

    My iPhone 4s was stolen this weekend and I did the Remote Lock.  What exactly does that do?  Also, if i do the Remote Wipe will that erase all of my data and impede anyone from ever using the phone?

    The remote lock locks the iphone with a passcode that you set. By remote wiping the device it will simply restore it and clear it of all its data, but by doing this it will prevent you tracking it and communicating with it (e.g. remote locking it) in the future

  • What exactly does the global switch command line do ?

    Hello All
    Just foraging in the dark world of APP-V. I have a question which I cannot find answer for through google.
    There are powershell commands to publish an APP-V application globally. What exactly does the global switch do ?
    I understand it makes the application available to everyone on the machine for anyone who logs onto that machine.
    However in the absence of this global switch the application is still available to all users who logon to that particular machine. So what exactly is the reason for using the global switch ?
    Thanks

    Correct, the global switch makes the application accessable for all users logging on to that system.
    This feature is required for some packages, like Office. But it is ofter used for applications used by everyone, like Adobe Reader.
    However in the absence of this global switch the application is still available to all users who logon to that particular machine. So what exactly is the reason for using the global switch ?
    A package can be added to the system but until it is published a user cannot start it. They won't see any shortcuts in their startmenu/desktop/etc.
    So after you added the package to the system, it must be published to a user or globally (every user) to start it.
