Importing and exporting FIM encryption key by MIISKMU.exe

Symptoms:

When starting User Profile synchronization server, ULS log contains following:

ILM Configuration: The miissku.exe process exited with error code -2147024894. Error: .
ILM Configuration: The ValidateMiisEncryptionKey process returned False.
Synchronization database is already initialized. Importing the encryption key for the database into the registry

UserProfileApplication.SynchronizeMIIS: Failed to configure MIIS pre database, will attempt during next rerun. Exception: System.NullReferenceException: Object reference not set to an instance of an object.     at Microsoft.Office.Server.Administration.UserProfileApplication.RestoreMiisEncryptionKey(ILMPostSetupConfiguration psc)     at Microsoft.Office.Server.Administration.UserProfileApplication.SetupSynchronizationService(ProfileSynchronizationServiceInstance profileSyncInstance).

ILM Configuration: The miissku.exe process exited with error code -2147024894. Error: .

ILM Configuration: The ValidateMiisEncryptionKey process returned False.

Issue:

Sync database is encrypted by the key, that wasn’t migrated to the new environment.

Resolution:

Correct way how to migrate encryption key during User Profile migration

[CURRENT ENVIROMENT] Export encryption key from current SharePoint environment by using miiskmu.exe (located in [drive]\Microsoft Office Servers\15.0\Synchronization Service\Bin\”

run: miiskmu.exe
- choose Export key
- specify credentials for farm administrator (account that is running user profile service, usually it is farm administrator account)
[NEW] Start service User Profile service
[NEW] Create new service application – User Profile Service Application by specifying all UPA databases
[NEW] Reset IIS and SPTimerV4 service
[NEW] Import encryption key
miiskmu.exe /i [PATH_TO_EXPORTED_KEY] {0E19E162-827E-4077-82D4-E6ABD531636E} /u:[FARM_ADMIN_LOGIN] *
[NEW] Start User Profile Synchronization service

How to force browsers to get latest script files on ASP.NET pages in automated way

Leave a reply

I was looking for a nice way how to force browsers to refresh its cached version of files and reload script files after the change occured.

Usually we link JS files or CSS files like this:

<script type='text/javascript' src="/_layouts/js/myJavascriptFile.js"></script>

1	<script type='text/javascript' src="/_layouts/js/myJavascriptFile.js"></script>

If you want to force refresh, you can amend parameters to url, ie.

<script type='text/javascript' src="/_layouts/js/myJavascriptFile.js?version=1"></script>

1	<script type='text/javascript' src="/_layouts/js/myJavascriptFile.js?version=1"></script>

Well, this is manual way, so how do it in automated way, so I do not have to care about it? There is several ways how to do it, I will just mention one, which is simple and reliable and you do not have to remember to increase anything upon deployment. (it’s not my idea, thanks to Adam Tegen and his answer in stackoverflow). I took the liberty to change it so it’s possible to use in ASP.NET webforms as well.

public static class VersionLinkHelper
{
    public static string GetVersion(string fileName)
    {
        var context = HttpContext.Current;

        if (context.Cache[fileName] == null)
        {
            var physicalPath = context.Server.MapPath(fileName);
            var version = "?v=" +
                new System.IO.FileInfo(physicalPath).LastWriteTime
                .ToString("yyyyMMddhhmmss");
            context.Cache.Add(physicalPath, version, null,
                DateTime.Now.AddMinutes(10), TimeSpan.Zero,
                CacheItemPriority.Normal, null);
            context.Cache[fileName] = version;
            return fileName+version;
        }
        else
        {
            return fileName + context.Cache[fileName] as string;
        }
    }
}

public static class VersionLinkHelper

{

public static string GetVersion(string fileName)

{

var context = HttpContext.Current;

if (context.Cache[fileName] == null)

{

var physicalPath = context.Server.MapPath(fileName);

var version = "?v=" +

new System.IO.FileInfo(physicalPath).LastWriteTime

.ToString("yyyyMMddhhmmss");

context.Cache.Add(physicalPath, version, null,

DateTime.Now.AddMinutes(10), TimeSpan.Zero,

CacheItemPriority.Normal, null);

context.Cache[fileName] = version;

return fileName+version;

}

else

{

return fileName + context.Cache[fileName] as string;

}

In ASP.NET page link the file as:

<script type='text/javascript' src='<%= VersionLinkHelper.GetVersion("/_layouts/js/CS/myJavascriptFile.js") %>'></script>

1	<script type='text/javascript' src='<%= VersionLinkHelper.GetVersion("/_layouts/js/CS/myJavascriptFile.js") %>'></script>
