What kind of reason could be? I tried to ping my host and I was getting packets from the host. this page If you want your application to detect the disconnections faster, then you must set the value of the tcp_keepalive_time, tcp_keepalive_interval, and tcp_keepalive_probes properties to a lower value at the operating system
According to my experiences it is commonly a network or firewall issue. Sql State = 08006 Error Code = 17 002 Websphere The problem i had was not a problem of the driver. For example, instead of the "jdbc:oracle:thin:@host:port:sid" connection string, you must use a connection string of the following form: "jdbc:oracle:thin:@(DESCRIPTION=" + "(ADDRESS_LIST=" + "(ADDRESS=(PROTOCOL=TCP)" + "(HOST=host)" + "(PORT=port)" + ")" + ")"
Typically, the remote host cannot be reached because of an intervening firewall, or if an intermediate router is down.

You can configure a preTestSQLString to test every connection obtained from the free pool before use in order to solve the problem.

For this reason, when setting up an MTS connection, the listener sends a redirect message back to the client asking the client to close the connection to the listener and connect Log into the remote host on which the Oracle instance is running and execute the appropriate command to determine what the server 'thinks' its hostname is (i.e. bilal haider Ranch Hand Posts: 47 I like...
