Hi All,

We're seeing this issue in the application server logs.

ORA-03135: connection lost contact

I'm just trying to understand what could be the exact reason. The server is online, no changes from OS side, I'm able to connect and run some queries in the Database etc...

When we run huge transactions, we're seeing this error coming up after 15-20 mins from the transaction's start point.

Could you advice any tools, traces I can use to find the exact reason?
