Oracle Enterprise Manager Grid control in 11g does not work well with fixed_date enabled. The database performance view is blocked totally. When you do need to work with fixed_date set it is possible to get past with a direct link to the view you want, but they will only work in historical mode. For example turn fixed date off, navigate to top activity, select historical and copy the url. This url will work with fixed_date set, though it is delayed by the frequency of AWR snapshots.

Streaming videos were sometimes slow replaying to a mobile application over the internet. On some networks they replayed fine and downloaded during playback as expected. On other and in some cases faster connections the client took up to a minute to download the entire file before beginning playback. The issue turned out to be the MIME settings on S3, by default S3 returned application/binary, setting the mime type to video/x-m4v resolved the problem.

An Oracle deployment on Windows 2008 with large page size enabled showed very low memory usage in task manager. The memory allocated with a large page size on Windows does not count as part of the process' working set since it is not pageable memory. Working set is what is displayed as memory usage in task manager. http://msdn.microsoft.com/en-us/library/aa366720(VS.85).aspx
