&lt;div class="content"&gt;
&lt;p&gt;When starting up Appian for the first time after a fresh installation, users may see the following error in the application server log:&lt;/p&gt;
&lt;pre&gt;com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 1000 bytes&lt;/pre&gt;
&lt;h2&gt;Cause&lt;/h2&gt;
&lt;p&gt;The MySQL storage engine was configured to use MyISAM instead of InnoDB as the storage engine. See the MySQL documentation &lt;a href="https://www.mysql.com/why-mysql/presentations/myisam-2-innodb-why-and-how/"&gt;here&lt;/a&gt; for further details on storage engines.&lt;/p&gt;
&lt;h2&gt;Action&lt;/h2&gt;
Make sure MySQL has the InnoDB engine by running the following command in MySQL:&lt;/div&gt;
&lt;div class="content"&gt;&amp;nbsp;&lt;/div&gt;
&lt;div class="content"&gt;&lt;code&gt;show engines;&lt;/code&gt;&lt;/div&gt;
&lt;div class="content"&gt;&amp;nbsp;&lt;/div&gt;
&lt;div class="content"&gt;Then, set the default storage engine to use InnoDB by running the following command in MySQL:&lt;/div&gt;
&lt;div class="content"&gt;&amp;nbsp;&lt;/div&gt;
&lt;div class="content"&gt;&lt;code&gt;set GLOBAL storage_engine=&amp;#39;InnoDb&amp;#39;;&lt;/code&gt;&lt;/div&gt;
