Logging access to a service in a Oracle DB

Hello everybody,

I had implemented audit access to WCF Services, where the log information is stored in a Oracle DB, but in the stress tests  with lots of concurrent service calls, the oracle connections falls, so audit not work in these cases. 

The main reason to log, not only for auditing, is to take services KPIs with some extra information saved in the  DB.

Do anyone implement some log service?

I am logging the start of the service, then the fail or success.


Thanks.

Braulio.
