ORA.NET 4.0 vs ORA.NET 3.55.XX

Post by Alladin » Tue 10 Jul 2007 01:21

I need some feedback to get started.

My company owns a license of 3.55.XX version, I just noticed that version 4.0 is out. However I couldn't see any reasons to upgrade yet.

Is there any real added value or just a marketing hype (citius-altius-fortius)?

What is really interesting for me is performance aspect. Is 4.0 faster than 3.55? Is it more robust & less buggier?

I use only few components like OracleConnection, OracleCommand & OracleDataReader... Are there any improvements in this area?

Thank you in advance,
