  • I had downloaded OS X Mountain Lion and had to replace my hard drive. Now when I try to download it only wants to upgrade since I show that I previously purchased it. What can I do to get the operating system back

    I had downloaded OS X Mountain Lion and had to replace my hard drive. Now when I try to download it only wants to upgrade since I show that I previously purchased it. What can I do to get the operating system back

    I'm unclear on what the problem is. Have you installed a system on the new hard drive, and if so, what system? Had you actually installed Mountain Lion previously, or only downloaded it? And what does "it only wants to upgrade" mean? Have you actually got Mountain Lion already installed? (See About This Mac in the Apple menu.)
    All Macs that shipped with Lion or newer are capable of internet recovery in situations like this. Just hold down command-R and it should start in recovery mode over the internet if necessary. You can reinstall the system from there. If you had Mountain Lion, I would assume that Mountain Lion would be the system you would get reinstalling that way.

  • Maintaining COMMAND in AIX / UNIX Operating system using Transaction SM69

    Hi,
    <b>I need to maintian command in AIX operating system by using transaction SM69.</b>
    Previously we were maintaining COMMAND in Windows NT Operating system using transaction SM69.
    There in SM69 we were using Operating System: Windows NT & OS command: cmd /k
    <b>But now we have to maintain in AIX Operating system.
    could any body tell for operating system: AIX, what "Operating system command" should i give..</b>
    If also I could get any link, that will be more helpful to me.
    Any help will be appreciated and rewarded.

    Hi Sameer,
    1. In case of AIX operating system,
        there is no need to give any such thing like CMD.
      In windows,
      (eg for DIR, we have to give CMD /C DIR)
    2. <b>But in AIX/UNIX, We directly need to give the final command.</b>
       eg: command is ls
       and in parameters we can give -la?
      (note, in aix/unix, command is case sensitive)
    regards,
    amit m.

  • Is any body work on oracle5 and forms 1 unix operating system

    if ther's any body who has worked on oralce5 and forms 1 (unix based).

    Hiya Steve.
    Pre Forms 2.0 Forms was around for a short time with Oracle 5, cos that was what I used in 1986 !!!
    If Toad will connect to your Oracle5 database (which it may not as it uses an earlier mode of sqlnet), it has the ability to extract data from tables as sql scripts..
    Anyway, export/import is still worth a go first.

  • What is latest Flash for Solaris/UNIX?

    Hello,
    I am currently running Firefox2 on Solaris 9 (UNIX) operating
    system.
    I have the following flash version installed:
    Flash Player 7 for Solaris
    Version 7.0.66.0
    September 2006
    When going to certain websites, they tell me that I need
    "Flash 8".
    I went to your download site and attempted to dowload "Flash
    9", but
    the download appears to be the same that I have installed:
    install_flash_player_7_solaris_sparc.tar.gz
    Question:
    Does Flash 8 or Flash 9 exist for Solaris/UNIX? If not, when
    would it
    be available? I am looking for the free version as I only use
    it for
    personal use.
    Thanks in advance.

  • What Operating system can I use.

    Hi,  I have a Power Book G4 - Tiger 10.4.11  (not Intel)
    What is the most up to date operating system I can get for my laptop?  And if so;
    will my iPhone 4S work on it?
    and the latest iTunes 10.5. ?
    Thank you
    Bernie

    The max OS for PowerPC Macs is Leopard 10.5.x. Also to use Apple iDevices you need Leopard & iTunes version 10.5.

    Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
    If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
    MB427Z/A  Leopard 10.5.1 install DVD
    MB576Z/A  Leopard 10.5.4 install DVD
    MB021Z/A  Leopard 10.5.6 install DVD (single user)

    After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
    The DVD should look like this
    Caution - Leopard does not support classic mode. So, if you currently open OS 9 apps in classic mode, you won't be able to do this if you upgrade to Leopard.

  • MS-DOS-COMPATIBLE  & UNIX COMPATIBLEAre these names of operating systems

    please rerer to above link----I have the following difficultiy
    i)     Could an  O/S  be added to any syntax groups?
    ii)     It is written for MS-DOS & UNIX   Suntax  groups -
    thier names to be
    MS-DOS-COMPATIBLE  & UNIX COMPATIBLE----
    Are these names of operating  systems or that these fielda are empty?

    Hi,
    This means that depending on your Operating System on which SAP is placed, you can mention the OS in Syntax group.
    DOS/Unix Compatibile simply means that your Syntax group would be able to work in DOS Operating System or Unix Operating system.

  • Renaming files with invalid characters in their names on NTFS partitions, introduced by operating systems other than Windows

    Essentially, Linux created some files with colons (:) in the name on a NTFS partition where I have Windows installed. I have since uninstalled Linux, but now I can only view these files in Windows Explorer. I can't open them, I can't even rename them to
    correct the problem. It's as if they don't exist, because of the invalid search paths.
    If I try to rename them in Windows Explorer I get following message.
    The file name you specified is no valid or too long.
    Specify a different file name.
    Well isnt' that something?... isn't that nice? Windows is able to display these files, but it doesn't allow me to open them and it certainly doesn't like me to rename them. So why is it whining about it then, when I'm trying to help? It says "try a different
    file name". Yeah, right! Like I haven't tried that one already! It doesn't matter what file name I input it will never accept it.
    So what am I supposed to do now? Ditch Windows and go back to Linux? Surely, Microsoft doesn't like the sound of that. Sure, I could reinstall Linux or run a Linux live system to correct the problem. But what good is Windows then? I might as well switch to
    Linux altogether.
    After doing some research I now know by fact that it's (kind of) possible to rename files from UNIX and UNIX-like operating systems to those compliant with Windows by using something called file name character translation. To some level this is essential and
    necessary for Windows interoperability with other operating systems (Windows is not the only operating system in the world). But this seems to be very complicated and I can't get my head around it. My brain is in overload. I don't know where to start.
    Once there was a...
    There's the Windows Services for UNIX (SFU) 1.0, 2.0, 3.0, 3.5. The first two versions were based on MKS Toolkit, a package licensed by Microsoft from MKS Inc. The later versions were based on the similar Interix product, after Microsoft purchased the company
    that made it.
    Then there's the new Subsystem for UNIX-based Applications (SUA). These are services for UNIX components. They are supposed to have Client for NFS v3 included as well. But the server components from the SFU line is missing (e.g. Server for NFS). These are included
    in Server editions of Windows.
    Then there's the Microsoft Knowledge Base article
    289627: "How to Enable File Name Character Translation". This article seems to describe exactly my situation.
    Windows and UNIX operating systems have restrictions on valid characters that can be used in a file name. The list of illegal characters for each operating system, however, is different. For example, a UNIX file name can use a colon (:), but a Windows
    file name cannot use a colon (:). If a UNIX user attempts to create a file with a Windows illegal character on a Windows Services for UNIX network file system (NFS) share, the attempt is unsuccessful and the UNIX client computer receives an input or output
    error.
    It goes further than that. At first glance, this KB article also seems to offer a solution to this exact problem, with examples as shown below.
    For example, the following maps the UNIX colon (:) to a Windows dash (-):
    0x3a : 0x2d ; replace client : with - on server
    I checked these values in charmap.exe and they are correct. Except for 2D not being a "dash", it's rather a hyphen ("hyphen minus" to be exact), but these two have pretty much the same appearance and they get interchanged a lot, I'm sure
    they are used to it by now. (Yes, the characters! They don't mind.)
    Then there's this registry key.
    HKEY_LOCAL_MACHINE\Software\Microsoft\Server For NFS\CurrentVersion\Mapping
    Well, of course, I don't have Server for NFS. So this is a dead end. Well, actually, it was a dead end from the beginning...
    1. First of all, I'm not working with a network share on a NAS or SAN storage. The files are on the local disk drive where Windows is installed, so that's a DAS for you.
    2. I don't have SFU! Well obviously, I'm on Windows Vista! So that means SUA!
    3. SUA are service components only. No server components. Can you guess what that means? Yeah... no "Server for NFS" since it's a server component.
    4. Windows Vista is a client side operating system! Server for NFS is only offered for use with Windows Server systems.
    5. Back to square one!
    So there you have it. They all lived happy for the rest of their lives...
    I'm stuck here. Can someone tell me what to do? I mean beyond the obvious option to use Linux to fixa a Windows problem? The NTFS file system itself supports colons in file names. It's Windows that doesn't, and so by default it proclaims it invalid character.
    Surely, even a Windows client operating system like Windows Vista should be able to allow the user to at least rename files with invalid characters to something more sensible (from the system point of view) and valid, if not being able to open them as they
    are. Just add some crazy voodoo code to it and it will work. If you can make it possible on Windows Server with UNIX user-mode subsystem on NT kernel, then what's stopping you from giving the Windows client system the same benefit?
    So what now? Purchase a Windows Server 2012 R2 license, copy my invalid files to a NAS share with NFS on a UNIX or Linux system, and have a go at the Windows registry and Server for NFS? Yeah... you're right, it's probably a bit over the top...
    On a second thought... I might as well install Linux again. There are countless situations where Linux has helped me solve problems related to, and more often than not caused by Windows.
