SharePoint - Clear Timer Timer Cache / Clear Configuration Cache

On number of occasions we may need to Clear SharePoint Configuration Cache, also known as SharePoint Timer Cache.  Let us consider one scenario; we have a SharePoint Farm with high availability (Streamlined topology with 4 Front End Web Servers), we want to change or reset Farm Passphrase. I changed the Passphrase successfully and now want to rejoin another Front End Webserver to the Farm which was disconnected earlier before resetting the Farm Passphrase.
Note: To know how to change the SharePoint Passphrase, please visit my article here.
I tried to run the Configuration Wizard on the Front End Webserver for rejoining it to the Farm and after entering the new Passphrase it stops with error "Could not connect to the Configuration Database, make sure the Passphrase it correct". 
To resolve this issue we need to clear the Configuration / Timer Cache from all the Servers on the SharePoint Farm, because the Farm is still using the Configuration Cache and we don't want SharePoint…

Reset your SharePoint Farm PassPhrase

If you forgot or missed or want to change your SharePoint Farm PassPhrase, here are the Powershell commands.

$PassPhrase = ConvertTo-SecureString -String “yourNewFarmPassPhrase” -asPlainText -Force

Set-SPPassPhrase -PassPhrase $PassPhrase -Confirm

Note: Comfirm your new PassPhrase and you are Done.

To make sure everything work perfectly after PassPhrase reset, you need to reset the Configuration / Timer Cache from all the Servers in the Farm. Please check my article for the same here.

SharePoint Solution (WSP) management using PowerShell

My recommended approach to manage SharePoint WSP solutions is; Powershell instead of GUI approach using SharePoint administration. Despite that, you can use the Central Administration to do that. Open SharePoint Powershell or windows Powershell using ‘Run as administrator’. If you open windows default Powershell , you need to load the SharePoint snap in explicitly, it auto loads in case of SharePoint Powershell.

PS C:\Windows\system32> add-pssnapin Microsoft.Sharepoint.Powershell

We will see some important Powershell cmdlet which are useful for solution management. (This article will be mainly focused on main parameters available with cmdlets, for all parameter details, please refer to Ms technet
