<h2 id="synopsis">Synopsis</h2>
<p>Automates the creation of database mirrors.</p>
<h2 id="description">Description</h2>
<p>Automates the creation of database mirrors.</p>
<ul>
<li>Verifies that a mirror is possible</li>
<li>Sets the recovery model to Full if needed</li>
<li>If the database does not exist on mirror, a backup/restore is performed</li>
<li>Sets up endpoints if necessary</li>
<li>Creates a login and grants permissions to service accounts if needed</li>
<li>Starts endpoints if needed</li>
<li>Sets up partner for mirror</li>
<li>Sets up partner for primary</li>
<li>Sets up witness if one is specified</li>
</ul>
<p>NOTE: If a backup / restore is performed, the backups will be left in tact on the network share.</p>

<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; $params = @{
&gt;&gt; Primary = 'sql2017a'
&gt;&gt; Mirror = 'sql2017b'
&gt;&gt; MirrorSqlCredential = 'sqladmin'
&gt;&gt; Witness = 'sql2019'
&gt;&gt; Database = 'pubs'
&gt;&gt; SharedPath = '\\nas\sql\share'
&gt;&gt; }
&gt;&gt;
PS C:\&gt; Invoke-DbaDbMirroring @params
</code></pre>
<p>Performs a bunch of checks to ensure the pubs database on sql2017a<br>
can be mirrored from sql2017a to sql2017b. Logs in to sql2019 and sql2017a<br>
using Windows credentials and sql2017b using a SQL credential.<br>
Prompts for confirmation for most changes. To avoid confirmation, use -Confirm:$false or<br>
use the syntax in the second example.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; $params = @{
&gt;&gt; Primary = 'sql2017a'
&gt;&gt; Mirror = 'sql2017b'
&gt;&gt; MirrorSqlCredential = 'sqladmin'
&gt;&gt; Witness = 'sql2019'
&gt;&gt; Database = 'pubs'

&gt;&gt; Force = $true
&gt;&gt; Confirm = $false
&gt;&gt; }
&gt;&gt;
PS C:\&gt; Invoke-DbaDbMirroring @params
</code></pre>
<p>Performs a bunch of checks to ensure the pubs database on sql2017a<br>
can be mirrored from sql2017a to sql2017b. Logs in to sql2019 and sql2017a<br>
using Windows credentials and sql2017b using a SQL credential.<br>
Drops existing pubs database on Mirror and restores it with<br>
a fresh backup.<br>
Does all the things in the description, does not prompt for confirmation.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; $map = @{ 'database_data' = 'M:\Data\database_data.mdf' 'database_log' = 'L:\Log\database_log.ldf' }
PS C:\&gt; Get-ChildItem \\nas\seed | Restore-DbaDatabase -SqlInstance sql2017b -FileMapping $map -NoRecovery
PS C:\&gt; Get-DbaDatabase -SqlInstance sql2017a -Database pubs | Invoke-DbaDbMirroring -Mirror sql2017b -Confirm:$false
</code></pre>
<p>Restores backups from sql2017a to a specific file structure on sql2017b then creates mirror with no prompts for confirmation.<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; Get-DbaDatabase -SqlInstance sql2017a -Database pubs |
&gt;&gt; Invoke-DbaDbMirroring -Mirror sql2017b -UseLastBackup -Confirm:$false
</code></pre>
<p>Mirrors pubs on sql2017a to sql2017b and uses the last full and logs from sql2017a to seed. Doesn't prompt for confirmation.<br></p>

<h5 id="enableexception">-EnableException</h5>
<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
