We are not able to connect to Oracle DB using SSH Tunnel(set up in putty) from our system command prompt. It is failing with below error:

Which failed as you can see. I guess I'm missing something, but what?
I'm getting started with Oracle Express. I used sqlplus to connect and create a new user then tried to use it with the password I gave it. Got a login error (tried 3 times with password I set). I'm surely missing something simple! What is my problem here?

Check contents of TNSNAMES.ORA. "My" XE database (the same version as yours) has alias pdb1:
PDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ods...r)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XEPDB1)
)
)
Then check SQLNET.ORA. "My" version looks like this (your should too, I'd say):
SQLNET.AUTHENTICATION_SERVICES= (NONE)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
Now, at operating system command prompt:

If foo is a local user, who exists only in container xepdb1, then the connect command should be connect foo#xepdb1. The connect command doesn't check to see where the user may exist (and indeed, different users by the same name may exist in different containers); you must include the container name in the command.
Perhaps you thought that, since you changed the container to xepdb1 (while connected as sysdba) already, the connect command would assume "within the same container". It does not.
Succeed with:
connect foo/bar#localhost:1521/xepdb1
I am trying to create a bash script to run an SQL query. The issue that I have is that the connection strings that I am using below is only giving me errors.
Example connection attempts with errors:
sqlplus -s username/password#hostname:Port:SID --> ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
sqlplus -s username/password#hostname:Port/SID ---> ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Example on my (local) XE database. Let's just check what TNSNAMES.ORA says (I obfuscated host name) so that you'd see what I used while connecting to the database. If you don't have TNSNAMES.ORA, then you'll have to find that info somehow (possibly by asking your DBA).
(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = my_host)(PORT = 1521))
(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE)))
OK, let's try it now:

Connecting successfully using SQL Developer but when i use sqlplus in Oracle Instant Client then i get following issues

Not Sure which of above is correct method and what is issue with connection string or any changes required on server side?
Note: I am able to connect another Oracle Server successfully. So no issue with InstantClient
Fixed using following:
./sqlplus egoint/egoint#(description=(address=(protocol=tcp)(host=139.138.267.202)(port=1521))(connect_data=(sid=EPROD)))
I am attempting to connect to an Oracle 11.2.0.2 64 bit database from a Win 7 and Win 8.1 machine with the Oracle 11.2.0.4 32 bit client. I can successfully ping the server and TNSPing the listener on both machines. But when I try to log into SQLPLus using system and my password I receive ORA-12560 TNS:Protocol Adapter Error. I can log into SQLPlus on the server. Any ideas? DB has been restarted as well as the listener. ORACLE_SID is set. I'm stuck...
If I'm following what you're seeing, it sounds like you just want to set the LOCAL enviroment variable on your Windows boxes to the TNS alias; then you don't have to supply that as you try to connect.
This is with the 12c instant client but the effect is the same with the 11g client. Specifying an alias as the connect strings works (the ORA-01017 is still coming from the DB):
c:\Program Files\instantclient_12_1>sqlplus -l x/y#abcd

ORA-01017: invalid username/password; logon denied
Connecting without the alias gets your ORA-12560:
c:\Program Files\instantclient_12_1>sqlplus -l x/y

ORA-12560: TNS:protocol adapter error
But if I set LOCAL then I can connect as if I had specified the alias:
c:\Program Files\instantclient_12_1>set LOCAL=abcd
c:\Program Files\instantclient_12_1>sqlplus -l x/y

You don't need to have ORACLE_SID set as that is only used for bequeath connections where the client and server are on the same box.
