VPN Oracle connection

Does anyone know if a VPN connection between a Cisco 1700 and a Cisco PIX 515 would cause a problem for an Oracle database connection. Like does the VPN time out after a couple minutes then come back alive after it is used? We have Oracle custom apps running at remote branches and it "rolls back" (drops connection) a couple times a day if it is left for more than 45 minutes. Just trying to see if it is a VPN issue or Oracle. The problem has yet to show up in the main office where the Oracle server is.

 what you are saying it sounds like it will be in the oracle somewhere because if a vpn connection is lost or reset for in activity you have to re-establish a connection it wont just connect again. and assuming you are doing the vpn from router to Pix firewall, it will keep the connection alive.
    Check the MTU on both the Firewall and the oracle connection try increasing it..
and see if that helps.
