Got more info on this: (I didn't do a find, but Network/admin didn't have a sqlnet.ora on the database side. The connection data... UID=applasn... DB... (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.70.44)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = asnq.domain.com))) About the sqlnet.ora... Yes, there is one. It resides at: /u001/app/oracle/10.2.0/network/admin/sqlnet.ora. The contents are...

There isn't any sqlnet.ora file on the database server. What we have: HP/UX B.11.11 U 9000/800 Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production With the Partitioning, OLAP and Data Mining options This is on the GA016d99 server as the database server. The application server is GA016A0G1. We have connections timing out in roughly 12 hours 20 minutes. So to further clarify the situation, we had nohup sql routines that would sleep for 5 minutes and request something. We also had 6 hours and rerun to test that, and one that would wait for the 12 hours and 20 minutes and rerun. We expected it to only time out the one over 12 hours, but ALL of them got canceled. That makes me think it is probably the Unix, or the network that just doesn't allow connections to exist over that period of time. Where do we start?
