hi,

Any or all of the following conditions may also apply:

1) You are able to establish a SQL*Plus connection from the same client to the same Oracle instance.

2) You are able to establish a JDBC OCI connection, but not a Thin

connection from the same client to the same Oracle instance.

3) The same JDBC application is able to connect from a different

client to the same Oracle instance.

4) The same behavior applies whether the initial JDBC connection

string specifies a hostname or an IP address.

Hi Ramesh,

Your error seems to be that you can not connect to the oracle database.

1. Check connection parameters

2. Check network settings (firewalls etc)

3. Check jdbc driver

More than likely though you just have some error in your connection parameters or the oracle db is unreachable to due to network configurations.

regards,

Dion
