SCVMM 2012 R2 – Dynamic Optimization Cannot Be Performed At This Time

Leave a reply

When trying to run the Optimize Hosts wizard within SCVMM 2012 R2 I received the error “Dynamic Optimization Cannot Be Performed At This Time” and “Object reference not set to an instance of an object”.

The Application Event Log on the SCVMM server contained a Windows Error Reporting event from the same time.  Opening the event showed a link to the error log.

Opening the error log showed that the error was related to a logical network issue on the cluster.  This cluster has a converged network switch to which all virtual machines (VMs) connect.  However, two additional logical networks are mapped to the switch to enable the migration of VMs which were connected to logical networks of a different name on a legacy cluster.

What I found is that some VMs were connected to the “Hyper-V External Access ” logical networks, rather than the ConvergedNetworkSwitch.  Changing the network mapping of the affected VMs to ConvergedNetworkSwitch enabled me to run the Dynamic Optimization wizard.

Updating The SharePoint 2010 CSV Bulk Taxonomy TermSet Importer/Exporter For SharePoint 2013

Leave a reply

The SharePoint 2010 CSV Bulk Taxonomy TermSet Importer/Exporter enables the import and export of taxonomies from the SharePoint Term Store.  It’s available on CodePlex and supports SharePoint 2010.  I like to use the tool to move taxonomies between development, test and live environments.  In this post I’ll show how to recompile the tool to support SharePoint 2013.

Download the source code from this page.  Extract the zip file and open the solution in Visual Studio 2012.  From Solution Explorer, right click on the project and select properties.

Change the target Framework to .NET Framework 4.

From Solution Explorer, expand References and right click on Microsoft.SharePoint and choose Remove.  Repeat for Microsoft.SharePoint.Taxonomy.

On your SharePoint server navigate to C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI.  Copy Microsoft.SharePoint.dll and Microsoft.SharePoint.Taxonomy.dll.  Paste them into the route folder containing the source code.

In Solution Explorer right click on References and choose Add Reference.  Click Browse and navigate to the folder containing the two dlls.  Add both the dlls to the project.

Right click on the Solution and choose Build Solution.

Copy the contents of the Debug folder to your SharePoint server and use the tool as described on CodePlex.
