I installed oracle 12c pn windows following the defaults settings... I end up with ORCL and ORCLPDB...

I can connect to ORCLPDB using EZCONNECT via CONN system/password@//localhost:1521/ORCLPDB . Then I added a service name in my tnsnames.ora like this : 

ORCLPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orclpdb)
    )
  )

But when I try connect system/password@ORCLPDB I get the following error :

ORA-12154: TNS:could not resolve the connect identifier specified

This is strange because lsnrctl services has the following entry :

Service "orclpdb" has 1 instance(s). Instance "orcl", status READY, has 1 handler(s) for this service... Handler(s): "DEDICATED" established:0 refused:0 state:ready LOCAL SERVER

What should I do ?

The problem is the TNS name which contains a leading whitespace.

For example:

[Whitespace]ORCLPDB = (DESCRIPTION = ...

As we know, the @ in connection string should immediately followed by the TNS name we can't have whitespace in front of a TNS name.
