<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance server1\instance1 -SingleUser
</code></pre>
<p>Will configure the SQL Instance server1\instance1 to startup up in Single User mode at next startup<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance sql2016 -IncreasedExtents
</code></pre>
<p>Will configure the SQL Instance sql2016 to IncreasedExtents = True (-E)<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance sql2016  -IncreasedExtents:$false -WhatIf
</code></pre>
<p>Shows what would happen if you attempted to configure the SQL Instance sql2016 to IncreasedExtents = False (no -E)<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance server1\instance1 -TraceFlag 8032,8048
</code></pre>
<p>This will append Trace Flags 8032 and 8048 to the startup parameters<br></p>
<h5 id="example-5">Example:  5</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance sql2016 -SingleUser:$false -TraceFlagOverride
</code></pre>
<p>This will remove all trace flags and set SingleUser to false<br></p>
<h5 id="example-6">Example:  6</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance server1\instance1 -SingleUser -TraceFlag 8032,8048 -TraceFlagOverride
</code></pre>
<p>This will set Trace Flags 8032 and 8048 to the startup parameters, removing any existing Trace Flags<br></p>
<h5 id="example-7">Example:  7</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance sql2016 -SingleUser:$false -TraceFlagOverride -Offline
</code></pre>
<p>This will remove all trace flags and set SingleUser to false from an offline instance<br></p>
<h5 id="example-8">Example:  8</h5>
<pre><code>PS C:\&gt; Set-DbaStartupParameter -SqlInstance sql2016 -ErrorLog c:\Sql\ -Offline
</code></pre>
<p>This will attempt to change the ErrorLog path to c:\sql. However, with the offline switch this will not happen. To force it, use the -Force switch like so:<br>
Set-DbaStartupParameter -SqlInstance sql2016 -ErrorLog c:\Sql\ -Offline -Force<br></p>
<h5 id="example-9">Example:  9</h5>
<pre><code>PS C:\&gt; $StartupConfig = Get-DbaStartupParameter -SqlInstance server1\instance1
PS C:\&gt; Set-DbaStartupParameter -SqlInstance server1\instance1 -SingleUser -NoLoggingToWinEvents
PS C:\&gt; #Restart your SQL instance with the tool of choice
PS C:\&gt; #Do Some work
PS C:\&gt; Set-DbaStartupParameter -SqlInstance server1\instance1 -StartupConfig $StartupConfig
PS C:\&gt; #Restart your SQL instance with the tool of choice and you're back to normal
</code></pre>
<p>In this example we take a copy of the existing startup configuration of server1\instance1<br>
We then change the startup parameters ahead of some work<br>
After the work has been completed, we can push the original startup parameters back to server1\instance1 and resume normal operation<br></p>
<h3 id="required-parameters">Required Parameters</h3>
<h5 id="sqlinstance">-SqlInstance</h5>
<p>The SQL Server instance to be modified<br />
If the Sql Instance is offline path parameters will be ignored as we cannot test the instance's access to the path. If you want to force this to work then please use the Force switch <br></p>

the OLE DB providers referenced by distributed queries, and automation objects referenced in Transact-SQL statements. The default is 256 MB.<br></p>
