function Update-DbaInstance { <# .SYNOPSIS Invokes installation of SQL Server Service Packs and Cumulative Updates on local and remote servers. .DESCRIPTION Starts and automated process of updating SQL Server installation to a specific version defined in the parameters. The command will: * Search for SQL Server installations in a remote registry * Check if current settings are applicable to the current SQL Server versions * Search for a KB executable in a folder specified in -Path * Establish a PSRemote connection to the target machine if necessary * Extract KB to a temporary folder in a current user's profile * Run the installation from the temporary folder updating all instances on the computer at once * Remove temporary files * Restart the computer (if -Restart is specified) * Repeat for each consequent KB and computer The impact of this function is set to High, if you don't want to receive interactive prompts, set -Confirm to $false. Credentials are a required parameter for remote machines. Without specifying -Credential, the installation will fail due to lack of permissions. CredSSP is a recommended transport for running the updates remotely. Update-DbaInstance will attempt to reconfigure local and remote hosts to support CredSSP, which is why it is desirable to run this command in an elevated console at all times. CVE-2018-0886 security update is required for both local and remote hosts. If CredSSP connections are failing, make sure to apply recent security updates prior to doing anything else. Always backup databases and configurations prior to upgrade. .PARAMETER ComputerName Target computer with SQL instance or instances. .PARAMETER Credential Windows Credential with permission to log on to the remote server. Must be specified for any remote connection. .PARAMETER Type Type of the update: All | ServicePack | CumulativeUpdate. Default: All Use -Version to limit upgrade to a certain Major version of SQL Server. .PARAMETER KB Install a specific update or list of updates. Can be a number of a string KBXXXXXXX. .PARAMETER Version A target version of the installation you want to reach. If not specified, a latest available version would be used by default. Can be defined using the following general pattern: <MajorVersion><SPX><CUX>. Any part of the pattern can be omitted if needed: 2008R2SP1 - will update SQL 2008R2 to SP1 2016CU3 - will update SQL 2016 to CU3 of current Service Pack installed SP0CU3 - will update all existing SQL Server versions to RTM CU3 without installing any service packs SP1CU7 - will update all existing SQL Server versions to SP1 and then (after restart if -Restart is specified) to SP1CU7 CU7 - will update all existing SQL Server versions to CU7 of current Service Pack installed .PARAMETER Path Path to the folder(s) with SQL Server patches downloaded. It will be scanned recursively for available patches. Path should be available from both server with SQL Server installation and client that runs the command. All file names should match the pattern used by Microsoft: SQLServer####*-KB###-*x##*.exe If a file is missing in the repository, the installation will fail. Consider setting the following configuration if you want to omit this parameter: `Set-DbatoolsConfig -Name Path.SQLServerUpdates -Value '\\path\to\updates'` .PARAMETER Restart Restart computer automatically after a successful installation of a patch and wait until it comes back online. Using this parameter is the only way to chain-install more than 1 patch on a computer, since every single patch will require a restart of said computer. .PARAMETER Continue Continues a failed installation attempt when specified. Will abort a previously failed installation otherwise. .PARAMETER InstanceName Only updates a specific instance(s). .PARAMETER Throttle Maximum number of computers updated in parallel. Once reached, the update operations will queue up. Default: 50 .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Install, Patching, SP, CU, Instance Author: Kirill Kravtsov (@nvarscar) https://nvarscar.wordpress.com/ Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires Local Admin rights on destination computer(s). .EXAMPLE PS C:\> Update-DbaInstance -ComputerName SQL1 -Version SP3 -Path \\network\share Updates all applicable SQL Server installations on SQL1 to SP3. Binary files for the update will be searched among all files and folders recursively in \\network\share. Prompts for confirmation before the update. .EXAMPLE PS C:\> Update-DbaInstance -ComputerName SQL1, SQL2 -Restart -Path \\network\share -Confirm:$false Updates all applicable SQL Server installations on SQL1 and SQL2 with the most recent patch. It will install latest ServicePack, restart the computers, install latest Cumulative Update, and finally restart the computer once again. Binary files for the update will be searched among all files and folders recursively in \\network\share. Does not prompt for confirmation. .EXAMPLE PS C:\> Update-DbaInstance -ComputerName SQL1 -Version 2012 -Type ServicePack -Path \\network\share Updates SQL Server 2012 on SQL1 with the most recent ServicePack found in your patch repository. Binary files for the update will be searched among all files and folders recursively in \\network\share. Prompts for confirmation before the update. .EXAMPLE PS C:\> Update-DbaInstance -ComputerName SQL1 -KB 123456 -Restart -Path \\network\share -Confirm:$false Installs KB 123456 on SQL1 and restarts the computer. Binary files for the update will be searched among all files and folders recursively in \\network\share. Does not prompt for confirmation. .EXAMPLE PS C:\> Update-DbaInstance -ComputerName Server1 -Version SQL2012SP3, SQL2016SP2CU3 -Path \\network\share -Restart -Confirm:$false Updates SQL 2012 to SP3 and SQL 2016 to SP2CU3 on Server1. Each update will be followed by a restart. Binary files for the update will be searched among all files and folders recursively in \\network\share.
