Farm Solution Deployment Lock and Removal

Farm Solution Deployment Lock may occur when a solution (.wsp) deployment fails unexpectedly.
Solution Deployment in SharePoint happens through the timer jobs. When you deploy a solution along with the deployment job a timer job named “Solution Deployment Job Lock” is created which store the deployment job’s id and the lifetime of the job is till the deployment job is completed. With this SharePoint ensures that no two deployments conflict with each other.

From the above we can conclude that in SharePoint one deployment job happens at a given time courtesy the solution deployment lock. Hence using this feature SharePoint ensures that no more than one deployment or retraction can happen at a given time.

So, why are we discussing this here. Ideally the lock is released once a deployment or retraction has been released, but there might be some cases when this lock doesn’t get released i.e. for some reason the timer job responsible for the lock does not get deleted. For instance as mentioned earlier that the solution deployment/retraction is done by a timer job and for some reason the timer service gets terminated leaving the lock unreleased.

To recover from this lock you need to use the following PowerShell command which releases the solution deployment lock.

Hiding SharePoint Lists

Sometimes we do feel a need to hide SharePoint Lists. Following are few ways which could some in handy while trying to achieve this objective.
Using SharePoint Designer:

  1. Start SharePoint Designer and open your site.
  2. Click on the “Lists and Libraries” in the Navigation pane
  3. Select the list/library which you need to hide
  4. On the details page check the “Hide from browser” checkbox and save
  5. To unhide the list un-check the checkbox and save 
sharepoint designer
SharePoint Designer

Using Code:
The other way is to obviously do this through code. SPList has a property as Hidden which can be set to true or false

using (SPSite site = new SPSite("http://YourSiteUrl"))
                {
                    using (SPWeb web = site.OpenWeb())
                    {
                        SPList list = web.Lists["Announcements"];
                        //Set this property to true or false accordingly
                        list.Hidden = false;
                        list.Update();
                    }
                }
