Any mechanism in Oracle could record the invocation of procedures?

Question

Hi guys,
Oracle 11gR2
We have plenty of procedures in several packages, they will be invoked by C# code. We need to record these invocations, that's when the call starts, write a log to the log table, and when the call ends, write another one.
I know that's a pretty simple requirement, I can write a procedure 'AddLog(...)', and call it in C# code before and after one procedure is called. This is, of course, a right way to go.
But I'm curious to know if there's a mechanism in Oracle could make it even simpler, for example, is there any system view which already contains this log info, or any system package which would be helpful to accomplish this task?
Thanks in advance.

Hi,
I've never tried it in a real-world scenario, but it looks promising - PL/SQL Hierarchical Profiler

Take a look at it, maybe it will provide more than you need, or maybe it would lead to performance degradation or something else that I'm not aware of ... Maybe someone else could provide useful info based on experience.
I'm also interested in this area, thanks in advance forum members.Hi, thank you. I didn't even heard about PL/SQL Hierarchical Profiler before. I have done some preliminary investigation, it's kind of close, but still doesn't quite meet the need. For example, we need to log it twice when calling a procedure, before the call and after the call. And we need to record the exception during the invocation. And in PL/SQL Hierarchical Profiler, it seems that it generate many other info that we don't need in table DBMSHP_FUNCTION_INFO.
I think we have to go back to use the common solution, write a logging procedure, and call it in C# app. But anyway, thank you very much.
