Idea Summary
When you execute a long time process in the DB you need to show to the user the progress. I implement this searching for a JS progress bar, using some Oracle tables, using callbacks on the page, etc… 

Use Case
For example a list of calls to a webservice to send some information, you need to show to the user the progress.

Preferred Solution (Optional)
It could be usefull a out of the box solution with a new component “ProgressBar” and an API (package) to simplify all the process.
