    <p>Anything that triggers a recompile (web.config change, app_offline.htm, .aspx file change, etc.) causes the CPU usage on the core to max out. If you repeat the process, it maxes out the CPU usage on the next core, until the overall CPU usage is at 100%. </p> <p>I hooked up windbg with sos extensions and it looks like for each maxed out core there is 1 thread stuck in System.AppDomain.Unload(System.AppDomain) and another stuck on Oracle.DataAccess.Client.OracleTuningAgent.DoScan().</p> <p>First thread</p> <ul> <li>Oracle.DataAccess.Client.OracleTuningAgent.DoScan()</li> <li>Oracle.DataAccess.Client.OracleTuningAgent.TuningFunction()</li> <li>System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)</li> <li>System.Threading.ThreadHelper.ThreadStart()</li> </ul> <p>Second thread</p> <ul> <li>System.AppDomain.Unload(System.AppDomain)</li> <li>System.Web.HttpRuntime.ReleaseResourcesAndUnloadAppDomain(System.Object)</li> <li>System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)</li> <li>System.Threading._ThreadPoolWaitCallback.PerformWaitCallbackInternal(System.Threading. _ThreadPoolWaitCallback)</li> <li>System.Threading._ThreadPoolWaitCallback.PerformWaitCallback(System.Object)</li> </ul> <p>It looks like AppDomain.Unload is waiting on OracleTuningAgent.DoScan to finish, but that thread is blocked or sleeping.</p> <p>Oracle has confirmed the issue (bug # 9648040) and it is a top priority. In the meantime, the possible workarounds are: </p> <ol> <li>Roll back to 11gR1/earlier client</li> <li>Add 'Self Tuning=false' to the connection string. You will of course lose the benefits of the automatic tuning.</li> </ol> <p>-Scott</p>

    1. COCheers Scott, this solved my problem, albeit a slightly different one. Basically my unit test runners were failing otherwise good tests because they could not unload their appdomain. Hope Oracle release a fix soon.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
