In my application I am using Oracle10g with Oracle11g client. But I face the following exception while connecting to database.
ORA-12154: TNS:could not resolve the connect identifier specified.
I could connect database with system.Data.OracleClient. But while using 11g client, I face connection problem,
Is this due to server version problem? or should I change my tnsnames.ora file.
Any changes should be made in web.config file
Help me resolving this.

u can use 11g client with oracle 10g DB.
it seems u r missing connection details in tnsnames.ora file...
or, if u earlier had 10g client and then installed 11g client, then there could be two oracle folders on your machine..... and u might be looking at wrong tnsnames.ora file while actual tnsnames file which is being used by oracle client is diffrent which
is missing connection details....
u can search for tnsnames.ora file on your machine and see if there are multiples of it...
for more info
hope this helps....
