ORA-12514: TNS [message #673388]

When I tried to connect as sqlplus / as sysdba
I get this error ORA-12514: TNS: the listener currently does not know about the service requested in the connect descriptor

This looks like a listener.ora

# tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.2/db_1/network/adm$
# Generated by Oracle configuration tools

ORCL12C =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl12c)
    )
  )

LISTENER_ORCL12C =
  (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))


ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

I guess I need to change something here, but I do not know what I do not have experience with the linux operating system

I have read that this problem can come in many ways, I tried to sql developer to connect as a sqlplus and since then I have this error.

ora-12514 ALWAYS only occurs due to a problem on DB Server system.
One cause of this problem is when the Oracle database is down & needs to be started.
A remote client send a request to the Listener asking to be connected to a specific service.
If/when the listener does not know anything about that service, the listener responds with ora-12514

post results from the following two OS commands:
lsnrctl status
lsnrctl service

Since every connection request to the listener gets logged, listener.log file will contain a line with 12514 as status code.

This line contains valuable debugging details. So post this line & surrounding lines.

for additional debugging suggestions read the URL below:

the error has changed now
ORA-12154: TNS:could not resolve the connect identifier specified

I changed the listener.ora, but I brought it back to the old one
I do not know what caused the error to change

ora-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ora-12154 NEVER involves the listener, the database itself or anything on the DB Server.
ora-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ora-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ora-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

A simple 'sqlplus / as sysdba' should not return any tns error, because it doesn't go through tns to make a local (BEQueath) connection.

You need to issue the following commands, then COPY and PASTE the entire command session, both the commands and the results:

env | grep ORA | sort
sqlplus / as sysdba

Once we see the output of that, we can know what to look at next. Until we see the output of that we are shooting in the dark.

Please realize & understand that NEVER in this thread have you actually SHOWED us the command that you report produces posted errors.

We can't say what you do wrong, since you refuse to show what you actually do.

BTW - listener.ora is NOT required to have the listener start & run without error.

>sqlplus / as sysdba
Above should connect to a local database which does NOT require use of SQL*Net.
Therefore should "never" throw ORA-12154 error.

This can results when OS/networking is mis-configured.
Simply put this system does not know who it is.

post results from OS commands below using COPY & PASTE showing actual commands issued.

ping <hostname>
ping <IP#>

where you supply correct values for placeholders within "<>" characters

You can connect to the DB so what problem remains?

Ctrl-C aborts current running command

man ping
man ls
man <command> provides online help for any/every shell command

I can only connect like this

echo $TWO_TASK
unset TWO_TASK
echo $TWO_TASK
sqlplus / as sysdba

If I insert sqlplus / as sysdba I get error

Because the listener does listen for a service named "orcl":

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

Services Summary...
Service "orcl12c" has 2 instance(s).
  Instance "orcl12c", status UNKNOWN, has 1 handler(s) for this service...
  Instance "orcl12c", status READY, has 1 handler(s) for this service...
The command completed successfully

It was TWO_TASK (without final S) but this does not change, it seems some files are missing.
I hope you have a good backup.
