Sql Solutions
Solution 1 - Sql
-
Go to the windows machine that hosts the Oracle database server
-
Go to Start -> Run -> Services.msc in Windows. Locate OracleService < SID > (here
OracleServiceORCL
) and click onStart
to start the oracle database service (if not already running) -
Once it is up and running, from the command prompt run the following:
tnsping < tnsalias >
(tnsalias entry you can find it in tnsnames.ora
file)
Solution 2 - Sql
In my case I didn't have an OracleService
(OracleServiceORCL) in Windows Services.msc
as described in Bharathi's answer.
I executed this command:
C:\> ORADIM -NEW -SID ORCL
and then the OracleService
called OracleServiceORCL just showed up and got started in Services.msc. Really nice.

Seems like database is not up. It might be due to restarting machine and the instance is not set to autostart and it so not started munually after starting from services Screen.
Just goto Command prompt
-
Set Oracle SID C:>set oracle_sid=ORCL
-
Now run Net start command. C:>net start oracleserviceORCL
Solution 4 - Sql
from command console, if you get this error you can avoid it by typing
c:\> sqlplus /nolog
then you can connect
SQL> conn user/pass @host:port/service
Solution 5 - Sql
Add to the enviroment vars the following varibale and value to identify the place of the tnsnames.ora file:
TNS_ADMIN
C:\oracle\product\10.2.0\client_1\network\admin

After searching alot got a simple way to solve it. Just follow the steps.
-
Check status of your listener.
- open command prompt and type
lsnrctl status
- You will get no listener.
- open command prompt and type
-
Now open
listener.ora
file which is present in following directory:C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN
- Open that file and change the host parameter with you computer name
- You can get your computer name by right click on
My Computer
and check you computer name, and replace host parameter with your computer name as follows:
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) (ADDRESS = (PROTOCOL = TCP)(HOST = Electron-PC)(PORT = 1521) ) ) )
So here you can observe
HOST = Electron-PC
, which is my computer name.- Save the listener.ora file and again return to cammand propt
3.Type the following in command prompt lsnrctl start
This will start the OracleTNSListner
.
you can check it in the service by opening services tab of Task Manager. if not started automatically you can start it.
Just this much and you are ready to work again on oracle.
Best of Luck.

In my case (for OracleExpress) the service was running, but I got this issue when trying to access the database via sqlplus without connection identifier:
sqlplus sys/mypassword as sysdba
To make it work I needed to add the connection identifier (XE for Oracle Express), so following command worked ok:
sqlplus sys/mypassword@XE as sysdba
If you still get ORA-12560, make sure you can ping the XE service. Use:
tnsping XE
And you should get OK message along with full connection string (tnsping command is located in oracle's installation dir: [oracle express installation dir]\app\oracle\product\11.2.0\server\bin). If you can not ping make sure your tnsnames.ora
file is reachable for sqlplus. You might need to set TNS_ADMIN environment variable pointing to your ADMIN directory, where the file is located, for example:
TNS_ADMIN=[oracle express installation dir]\app\oracle\product\11.2.0\server\network\ADMIN
Solution 8 - Sql
Quite often this means that the listener hasn't started. Check the Services panel.
On Windows (as you are) another common cause is that the ORACLE_SID is not defined in the registry. Either edit the registry or set the ORACLE_SID in a CMD box. (Because you want to run sqlplusw.exe I suggest you edit the registry.)

I have solved the problem the easy way. My oracle was running just fine in the past. After I installed MS SQL Server was when I noticed this problem. I just uninstalled MS SQL Server on my machine then the problem was gone. Make sure you restart your computer after that. Now I can connect to Oracle database through SQLPlus again. My guess is that there's some conflict between the two. Hope this helps.

Another possible solution that just worked for me...considering I was using my local login as the dba permissions.
Follow the steps to get to Services. Right click on the instance and go to 'Log On'? (might not be the name but it's one of the tabs containing permissions). Change the settings to use LOCAL.
Solution 11 - Sql
If none the above work, then try this :
Modify the LISTENER.ora
(mine is found in : oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
) ==> add a custom listener that points to your database(SID), example my SID is XZ0301, so :
## Base XZ03001
SID_LIST_LISTENER_XZ03001=(SID_LIST=(SID_DESC=(ORACLE_HOME =
E:\oracle\product\11.2.0\dbhome_1)(SID_NAME= XZ03001)))
LISTENER_XZ03001=(DESCRIPTION_LIST=(ADDRESS=(PROTOCOL =
TCP)(HOST=MyComputerName)(PORT= 1521)))
DIAG_ADR_ENABLED_LISTENER_XZ03001=ON
ADR_BASE_LISTENER_XZ03001=E:\oracle
Restart your machine
For Windows 7, use the following to modify the LISTENER.ora:
- Go to Start > All Programs > Accessories
- Right click Notepad and then click Run as Administrator .
- File>open and navigate to the tnsnames.ora file.
- Make the changes then it should allow you to save

It really has worked on my machine. But instead of OracleServiceORCL I found OracleServiceXE.

Flow the flowing steps :
-
Edit your listener.ora and tnsnames.ora file in $Oracle_home\product\11.2.0\client_1\NETWORK\ADMIN location
a. add listener.ora file
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) )
)
ADR_BASE_LISTENER = C: [here c is oralce home directory]
b. add in tnsnames.ora file
SCHEMADEV =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dabase_ip)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = SCHEMADEV)
)
)
2. Open command prompt and type
sqlplus username/passowrd@oracle_connection_alias
Example :
username : your_database_username
password : Your_database_password
oracle_connection_alias : SCHEMADEV for above example.

Just to add up, follow the screenshot and choose local account to start if not selected. Then start the service.
Solution 15 - Sql
You need to tell SQLPlus which database you want to log on to. Host String needs to be either a connection string or an alias configured in your TNSNames.ora file.
Solution 16 - Sql
ORA-12560: TNS:erro de adaptador de protocolo
- set Environment Variables: ORACLE_BASE, ORACLE_HOME, ORACLE_SID
- make sure your user is part of ORACLE_GROUP_NAME (Windows)
- make sure the file ORACLE_HOME/network/admin/sqlnet.ora is: SQLNET.AUTHENTICATION_SERVICES = (NTS)
- (Windows) Be carefull when you add a new Oracle client: adding a new path to the PATH env. variable can mess things up. The first entry in this variable makes a difference: certify that the sqlplus executable in the ORACLE_HOME (ORACLE_HOME/bin) comes first in the PATH env. variable.
Solution 17 - Sql
I try 2 option:
- You change service OracleService in Service Tab -> Running
- Login with cmd command: sqlplus user_name/pass_word@orcl12C Note: orcle12c -> name of OracleService name run in you laptop

In my case, (ORA-12560: TNS protocol adapter error)Issue cause of database connection issue like database, user name and password.
Once you got the issue. Initially you have to check connection details, after check the oracle service and further more.
I missed some connection details, So only i got TNS protocol adapter error, I will changed the connection details, It would be working fine.
