<h2 id="synopsis">Synopsis</h2>
<p>Evaluates tempdb against several rules to match best practices.</p>
<h2 id="description">Description</h2>
<p>Evaluates tempdb against a set of rules to match best practices. The rules are:</p>
<ul>
<li>TF 1118 enabled - Is Trace Flag 1118 enabled (See KB328551).</li>
<li>File Count - Does the count of data files in tempdb match the number of logical cores, up to 8?</li>
<li>File Growth - Are any files set to have percentage growth? Best practice is all files have an explicit growth value.</li>
<li>File Location - Is tempdb located on the C:? Best practice says to locate it elsewhere.</li>
<li>File MaxSize Set (optional) - Do any files have a max size value? Max size could cause tempdb problems if it isn't allowed to grow.</li>
<li>Data File Size Equal - Are the sizes of all the tempdb data files the same?</li>
</ul>
<p>Other rules can be added at a future date.</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>
