#ValidationTags#CodeStyle,Messaging,FlowControl,Pipeline# function Install-DbaMaintenanceSolution { <# .SYNOPSIS Download and Install SQL Server Maintenance Solution created by Ola Hallengren (https://ola.hallengren.com) .DESCRIPTION This script will download and install the latest version of SQL Server Maintenance Solution created by Ola Hallengren .PARAMETER SqlInstance The target SQL Server instance onto which the Maintenance Solution will be installed. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database The database where Ola Hallengren's solution will be installed. Defaults to master. .PARAMETER BackupLocation Location of the backup root directory. If this is not supplied, the default backup directory will be used. .PARAMETER CleanupTime Time in hours, after which backup files are deleted. .PARAMETER OutputFileDirectory Specify the output file directory where the Maintenance Solution will write to. .PARAMETER ReplaceExisting If this switch is enabled, objects already present in the target database will be dropped and recreated. .PARAMETER LogToTable If this switch is enabled, the Maintenance Solution will be configured to log commands to a table. .PARAMETER Solution Specifies which portion of the Maintenance solution to install. Valid values are All (full solution), Backup, IntegrityCheck and IndexOptimize. .PARAMETER InstallJobs If this switch is enabled, the corresponding SQL Agent Jobs will be created. .PARAMETER LocalFile Specifies the path to a local file to install Ola's solution from. This *should* be the zipfile as distributed by the maintainers. If this parameter is not specified, the latest version will be downloaded and installed from https://github.com/olahallengren/sql-server-maintenance-solution .PARAMETER Force If this switch is enabled, the Ola's solution will be downloaded from the internet even if previously cached. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .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: Ola, Maintenance Author: Viorel Ciucu, cviorel.com Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK http://dbatools.io/Install-DbaMaintenanceSolution .EXAMPLE PS C:\> Install-DbaMaintenanceSolution -SqlInstance RES14224 -Database DBA -CleanupTime 72 Installs Ola Hallengren's Solution objects on RES14224 in the DBA database.
