How Does Oracle SQL Developer configure TNS and ipvtns?

When oracle SQL Developer 4.0.3.16 is installed, if the connection type is "TNS" and the network alias cannot be obtained, how can I set it to access the TNS file?

In this case, set the TNS_ADMIN environment variable to point to the directory where the tnsnames. ora file is located. The simplest method is as follows:

C: \ Users \ konglb> set tns_names = C: \ OracleClient \ Oracle32 \ product \ 11.2.0 \ client_1 \ network \ admin

C: \ Users \ konglb> echo % TNS_ADMIN %

C: \ OracleClient \ Oracle32 \ product \ 11.2.0 \ client_1 \ network \ admin
