対策
RESOLUTION 1:
1. Shut down Toad for Oracle.
2. Right click on My Computer and select Properties. Click on the 'Advanced System Settings' link on the right hand side. Click on Environment Variables button.
3. Under System Variables, click the ‘New’ button.
4. For Variable name, enter TNS_ADMIN.
5. For Variable value, enter the directory that contains your TNSNAMES.ORA file.
Click OK until one returns to the Desktop.*Note if one has other Oracle clients installed on the machine the TNS_ADMIN variable will force the same TNSNAMES.ORA file on all installed clients. If need be, alter the TNS_ADMIN variable to the appropriate directory.
6. Launch Toad. At the connection window, select the TNS tab. The connection window lists the databases from the TNSNAMES.ORA file specified in TNS_ADMIN variable.
7. Select a database; enter the User/Schema name and Password. Click Connect to connect to the database.

Extract all Instant Client files to one directory file length path.Example: C:\Ora12c_32bitNOTE: If you downloaded the SQL Plus tool, extract all the files to the same location as the Instant client files. i.e. C:\Ora12c_32bit.B.
