What do I do if I have backup problems on a 64-bit OS?

Problem with NTBackup

On 64-bit systems, a DataMiner backup procedure can fail with the following message:

Backup job had errors!! Backup-process failed. The system cannot find the file specified.(2)

This error is caused by SLDMS being unable to start or locate the ntbackup process.

To solve this problem, proceed as follows:

  • Copy the ntbackup.exe file from the C:\WINDOWS\system32 directory of a 32-bit system to the C:\Skyline DataMiner\Files directory of the 64-bit system.

Problem with DataMiner database dump

On 64-bit systems, a DataMiner backup procedure can fail the moment a database dump has to be performed for a legacy MySQL database.

This error is caused by SLDMS being unable to start or locate mysqldump.exe.

To solve this problem, proceed as follows:

  • Create a dummy C:\MySQL\bin directory containing the mysqldump.exe file.

How do I configure IIS 6 on a 64-bit system?

Problems with an incorrect IIS configuration

When IIS is incorrectly configured, the following problems may occur:

  • When browsing to the DMA:

    Service Unavailable

  • Errors coming from W3SVC-WP in the event viewer of the DMA:

    Id 2268: Could not load all ISAPI filters for site/service. Therefore startup aborted.
Id 2274: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_filter.dll could not be loaded due to a configuration problem [...]
Id 1062: It is not possible to run different versions of ASP.NET in the same IIS process. Please use the IIS Administration tool to reconfigure you server to run the application in a separate process.

  • When browsing to ASP.NET applications (Dashboards):

    404 (Not Found)
403 (Forbidden)

To avoid these problems, first of all make sure that the following programs/frameworks are installed:

  • IIS
  • .NET Framework 3.5

If they are, make sure IIS has been correctly configured. See Correctly configuring IIS 6.

Correctly configuring IIS 6

To correctly configure IIS, on top of the standard DataMiner Agent installation, do the following:

  1. Open a command prompt window, by going to Start > Run and entering cmd.

    Note

    It is advisable to run cmd.exe as an Administrator.

  2. Type the following command, and then press ENTER:

    Cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs
SET W3SVC/AppPools/Enable32bitAppOnWin64 1

  3. Type the following command, and then press ENTER:

    %SYSTEMROOT%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

  4. Type the following command, and then press ENTER:

    %SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

  5. Open IIS Manager.

  6. In the Web Service Extensions list (see left tree pane), set the following extensions to "Allowed":

    • ASP.NET version 1.1.4322
    • ASP.NET version 2.0.50727
    • Active Server Pages

  7. In File Explorer, execute C:\Skyline DataMiner\Tools\ConfigureIIs.js. When the execution is ready, a message box will appear.

  8. In the left pane of the IIS Manager, open the website and verify that the Dashboards item is an application (cogwheel icon).

    If it is not, proceed as follows:

    1. Right-click > Properties
    2. Click Create Application.
    3. On the Documents tab, make sure that the default document is "default.aspx".
    4. On the Directory Security tab, click Edit (next to Authentication and access control), and make sure that "Integrated Windows Authentication" is selected.

  9. Restart IIS:

    • In the left pane, right-click COMPUTERNAME and select All Tasks > Restart IIS.

What do I do if there is an error when the MySQL service is started?

After installing MySQL, the following error may occur when the MySQL service attempts to start:

MySQL service cannot start (event viewer error message: Default storage engine <InnoDB> is not available)

To resolve this issue, proceed as follows:

  1. Go to the MySQL Server installation directory:

    • On an x86 machine: C:\Program Files\MySQL\MySQL Server x.x\Data
    • On an x64 machine: C:\Program Files(86)\MySQL\MySQL Server x.x\Data

  2. Remove the following files:

    • ib_logfile0
    • ib_logfile1
    • ibdata1

  3. Start the MySQL service manually.
