Cannot connect to oracle pluggable database - oracle

Question

Iinstalled oracle in my Windows 10 64 bit pc and I started doing verification steps mentioned in the tutorial which's given in the oracle website which can be found in the link below.
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/12c/r1/Windows_DB_Install_OBE/Installing_Oracle_Db12c_Windows.html
When I try to connect to my pluggable database using this command
C:\Users\Chathura>sqlplus sys/Oracle_1#orclpdb as sysdba;
it gives me following message
SQL*Plus: Release 12.2.0.1.0 Production on Tue Jan 30 19:34:25 2018
Copyright (c) 1982, 2016, Oracle. All rights reserved.
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
Enter user-name:
But when I try to connect to container database it connects successfully.
This is how I created pluggable database.
I read articles regarding this tried adding TNS_ADMIN system variable too, but non of those worked.
What I am doing wrong here?

Answer 1

You have to use the service name for your pluggable, you can't use the SID..that's only going to work for the container.
So find out the service name
[oracle#vbgeneric ~]$ lsnrctl status

The command completed successfully
[oracle#vbgeneric ~]$
Then connect, use #servicename vs #SID
in my case that's #orcl
Or connect to your container, then switch over to your PDB
oracle#vbgeneric oracle]$ sqlplus sys/oracle#orcl12c as sysdba

Answer 2

connect to your database ( pluggable database) and make thing configuration
`
startup mount;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
`
and also that
`
update sys.props$ set VALUE$='WE8MSWIN1252' where NAME='NLS_CHARACTERSET';
commit;
shutdown immediate;
startup;
`
after that just check your tnsnames.ora`enter code here`

Answer 3

WINDOWS 10:
Don't know if this is exactly your problem, but I got one very similar. After creating new users to PDB, I couldn't connect to Database. Here is what I did (don't know if you need all of this, but it worked for me).
Try this options on SQL Dev Connection:
connection
On $ORACLE_HOME/network/admin add:
ORCLPDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orclpdb)
)
)
On network/admin/sqlnet.ora file add:
SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8
