Intermittent connection errors

Hi!

 

 

I have also the same issue even after following the deployment guide "Oracle Database and RAC (BIG-IP LTM)" (document is 'oracle-rac-database-dg.pdf)

 

I'm able to connect with SQL Developer but after a while (more or less 5 min, 300 sec which is the default TCP timeout if I'm right) I'm getting a reset and I get the following error message in SQL Developer :

 

"Your database connection has been reset. Any pending transactions or session state has been lost."

 

 

Then if I retry, it's ok, I'm getting re-connected.

 

 

I'm missing something in one of (or the two ?) TCP profiles but what ?
