Suddenly, my webapps (Java project) in Eclipse can't start. In the log it says that it failed to make a
Ns Main Err Code: 12564
connection to the Oracle database, with some error listener in it. So I try to connect the database manually from the SQL developer. It says ORA-12528: TNS:Listener: All Appropriate instances are blocking new connections. I've read some solutions, and I tried to restart the Oracle services including the orcl and listener. After I restarted it, the error becomes ORA-12505: TNS:listener does not currently know of SID given in connect descriptor. After a while, it becomes ORA-12528 again. Can someone help?

Our database is behind a firewall. Firewall has an "idle session timeout" value. If a connection remains idle for more than the "idle session timeout" value it drops the connections.Application developers usually configure their connection pools to remain alive for a long time, which is more than the "idle session timeout" value of the firewall. Not all the connections in the pool are used. Some stays idle. After sometime the firewall drops them and I get those operation timed out problems. Solution / Workaround: 1) Add the following line to the sqlnet.ora file on the server. SQLNET.EXPIRE_TIME=10In this configuration database will probe the application servers every 10 minutes to see if they are up. In fact this is a mechanism to determine stale connections by database.

Try looking at your TNSNAMES entry (HOST), the port and check that your firewall has the port open. -------------------- Kent Crotty ShawJ View Member Profile Aug 17 2007, 07:13 AM Post #3 Advanced Member Group: Members Posts: 60 Joined: 6-August 07 Member No.: 10,889 Make sure that the listener and netca are running. You might also need to check your registry. many times this error occurrs when a registry value has been changed. « Next Oldest · Oracle Forum · Next Newest » 4 User(s) are reading this topic (4 Guests and 0 Anonymous Users) 0 Members: Forum Home Search Help Oracle |-- Oracle Forum Display Mode: Standard · Switch to: Linear+ · Switch to: Outline Track this topic · Email this topic · Print this topic · Subscribe to this forum Lo-Fi Version Time is now: 15th October 2016 - 10:35 AM Powered By Invision IPB © 2016 IPS, Inc.
