Oracle 11g client installed in a public place on c:\ in windows. For example, c:\oracle\production\client_1, but tnsnames.ora and sqlnet.ora files are located in another driver. For example, e:\oracle\files\tnsnames.ora and sqlnet.ora. The two files can't be copied to Oracle home on c:\. Can the databases in the tnsnames.ora be connected and how to do that?
