<p>In your workplace, where do you store your common, non-database specific scripts that you use in SQL Server? Do you keep them in .SQL scripts on the file server, do you store them in the Master database, or do you keep them in a database you defined specifically for these kinds of things?</p>
| <p>We store them as regular source code, so in version-control.
You have then available previous versions of script, and you avoid "someone deleted the XY script" risk.</p>

<p>I need to handle massive (tens of millions) of MATLAB structs; I needed a dozen or so fields so I reckoned memory won't be an issue until I discovered this (<a href="http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/matlab_prog/brh72ex-2.html" rel="nofollow noreferrer" > ... | <p>Convert these structs into arrays, and then provide accessor methods via a class.</p>

The same app on other servers does not exhibit this behavior. This happens on WebSphere and Tomcat. The environment is tricky to set up so it is diffic... | <p>If you are using Java 5 or later, you can connect to your application using <a href="http://docs.oracle.com/javase/6/docs/technotes/guides/management/jconsole.html" rel="noreferrer">jconsole</a> to view all running threads. jstack also will do a stack dump.
