Do you really need to limit users in the way with an integration server. I think that's why CC.Net doesn't have that sort of support built in.</p>

<p>We are leveraging CC.NET to both run a CI build, as well as being able to use the Force Build feature to do a Build + Deploy. That is why we want hands off the dashboard.</p>

<p>Right now I have a few new applications being developed against an Oracle Database, and sometimes they crash or fail to end correctly, etc... anyways the problem is they sometimes seem to leave their connections open, and I need to cleanup after them.
My question is if there is a way from the database-side of things... | <p>Here's a page referring to connection timeout parameters you can set in <a href="http://download.oracle.com/docs/cd/B28359_01/java.111/e10788/optimize.htm#sthref181" rel="nofollow noreferrer">Oracle 11g</a>. I think the 'Abandon Connection Timeout' is what you're looking for. </p>
