Oracle Client Connecting to Database without tnsnames.ora file
I ve installed oracle client in one of my desktop . i made entries in the tnsnames,.ora file for the connect string and the connection was thro and working perfectly. now i deleted the tnsnames.ora file from the machine and still iam able to connect to the database from the client machine with the same connect string but iam not able to connect using any othe connect string value.
how does a client connect to the server without referring to the tnsnames.ora file. is there any other file which it could refer to .pls clarify me on this.
thanks in advance
