“The specified database is not a valid synchronization database” issue

Good Day Everyone,

Let me guess , if you are reading this article possible you may in the middle of a restore or migration issue and not able to restore User Profile Service Application .
This warning means you can not restore old sycronization database (default name is Sync DB) .This is a by design issue and you do not allowed to do it. that’s why you are getting fallowing warning.  For resolution just create a new Syncronization database. Don’t worry about the content in it because SharePoint will rebuild it once you configured User Profile Service Application correctly.

 

How to collect IIS Logs for a SharePoint Web Application

Hello All,

When working with Microsoft Support for some cases the support engineers ( like me ) may request IIS Logs for investigation.
So in this article i am going to tell how you can collect IIS Logs correctly.

1) You have to detect your IIS Web site on IIS Console because your site url and your web application name can be different.
First connect your Central Administration and click “Managed Web Application”‘s link .

but my Web Application Name is SharePoint – 8080

2) Open your IIS Manager and find and click your webapplication name

3) Click the “Advanced Settings” in Action pane.

4) Please not your IISsite ID for this example is 1442344892

5) Click “Logging” icon

6) Detect where the IIS logs are kept in which folder

7) Open this folder in Windows Explorer and find your related folder in it according your IISSite ID. In this scenario the folder is W3SVC1442344892
You can open windows explorer by “Start” -> “Run” and copy paste highlighted path on above screenshot and press enter.

8) Open that folder and order by “Modified Date” as descending order

9) Collect your files according to occurrance time of your problem or issue. If you have a workspace opened by Microsoft and your file size are big , you can compress the files with a compression program.

Notes: IIS buffers the logs in memory for a while before write to the log file (until log buffer chuck size has reached its max size). If you want to catch latest records you may need to do an iisreset or open a command prompt and type  “netsh http flush logbuffer” (this command will provide http.sys to flush logs.)
to force iis write cached log chunk to log file. If you are searching for old records that “Modifed Date” earlier than last log date you dont need this operation.

Have a nice log hunting 🙂

If you are getting “Method not found” (MissingMethodException) error in SharePoint 2010

“Method not found” error i admit its my favorite 🙂 If you get this MissingMethodException from any of your build in SharePoint assembly for example below “Microsoft.SharePoint.Library” the first place you may check the dlls versions. This error usually caused by some version mismatch between your related dll version and SharePoint version.

You can see the error samples below:
Exception information:
Exception type: MissingMethodException
Exception message: Method not found: ‘Void Microsoft.SharePoint.Library.SPRequestInternalClass.AddOrUpdateItem(System.String, System.String, Boolean, Boolean, Boolean, Boolean, Boolean, Int32 ByRef, System.String ByRef, System.Guid, Boolean, System.String, System.Object ByRef, System.Object ByRef, System.Object ByRef, Boolean, Boolean, Boolean, Boolean, System.String, Microsoft.SharePoint.Library.ISP2DSafeArrayWriter, Microsoft.SharePoint.Library.ISP2DSafeArrayWriter, Microsoft.SharePoint.Library.ISP2DSafeArrayWriter)’.

So what could cause this issue
1) Unsuccessful upgrade or a corrupted installation.
2) Custom solutions that referenced old dlls
3) Deploying SharePoint solutions which is accidentally overwriting old dll on new version.
4) Unnecessery GAC registrations for build-in SharePoint DLLs

In this scenario we don’t have any custom solutions . So we may facing with first issue above, so how to fix the issue:
1) Define that which dll in use and this exception has thrown up. Answer for this scenario is “Microsoft.SharePoint.Library.dll”
2) Check the all dll versions in your system and compare with your SharePoint Build Number from Central Administration- > Migration and Upgrade -> Check product installation and patch status.
Here you can find powershell commands for searching versions of specific file in your system.
https://blog.bugrapostaci.com/2011/12/26/powershell-find-files-with-versions/
3) Correct dll version if you have orginal version of this old dll.
or
4) Upgrade your SharePoint for  newer version of Cumulative Update than your build will solve this issue.

By the way if you are thinking the problem caused by a Custom Solution you may check fallowing article:

Have a nice day.

 

MOSS 2007 – Search “The gatherer is shutting down” error

When try to open search setting page if you are getting fallowing error :

Possibly you have a hang issue on one of your WFE server’s Office Server Search service.
1) Check your topology from Central Administration – > Servers in Farm section and define which SharePoint servers responsible for running search.
2) Connect all that machines and open services.msc and check status of Office Server Search Service.
3) If you find a service in “stopping” state open a task manager
4) kill the mssearch.exe process .after killing this process your Office Server Search service should go “stop” state.
5) Restart the service and check does your problem has been fixed.

Also restarting server can fix this problem but if you don’t want to restart you can fallow up above solution.
