Server Administration :: Unable To Connect To Database / ORA-12560 / TNS / Protocol Adapter Error
Feb 7, 2013
In one machine I have windows xp with Oracle 11.2.0.2 database installed and I am able to connect to the database using both sql developer and sql plus.
In another machine I have windows 7. I installed Oracle client 11.2.0.1, then using Net configuration tool, I installed both listener.ora and tnsnames.ora files.
Now, I want to connect to the database which is installed on windows xp from windows 7 using the oracle client. When I tried to connect, I got the following error :
ERROR:ORA-12560: TNS:protocol adapter error
In order to rectify the above error, I was making sure that ORACLE_HOME AND ORACLE_SID were properly set in the regedit file (under HKEY_LOCAL_MACHINE > SOFTWARE > ORACLE). The ORACLE_HOME was set properly. But I found ORACLE_SID missing. So I added ORACLE_SID environment variable in the registry and re-tried connecting to the database. But I am not able to connect. What else should I do in order to connect?

We installed Oracle 11g on solaris machine but some of the configuration failed.
When verified in tracelog we are finding below error message:
PRCT-1003 : Failed to run "getcrshome" on node "localnode"
at oracle.cluster.deployment.ClusterwareInfo.getConfiguredCRSHome(ClusterwareInfo.java:423)

We then tried to create instance but came up with below error:
ORA-12560: TNS Protocol Adapter Error..We have another database version 10.2.0.3 running on the same server and needs to be continued.

I installed local database on my laptop that pc is inside a domain when i remove the network cable and connect using the sid defined in the tnsnames sys/sys@ora10g as sysdba it gives me that errors
ORA-12560: TNS:protocol adapter error
to resolve this problem i should connect like that sys/sys as sysdba without the sid but i don't want to connect in this way because i have work must be done from home on that local database so i don't want to connect with network sys/sys@ora10g as sysdba and without network sys/sys as sysdba.
i want to be always connect sys/sys@ora10g as sysdba.

Since 13.00 hours, my clients can't connect to the database, and hence cannot access their application.
They get a ORA-12560 error. protocol adapter.
What I have discovered and done so far.
1. I can tnsping dbname -> OK.
2. I have rebooted both application server and databaseserver multiple times
3. I haven't touched tnsnames.ora, sqlnet.ora and listener.ora and they look to be in perfect mint condition.
4. I have full access to access the database instance via web.
5. I can connect to the database instance via sql
6. I have restarted the oracle-services: oracleDBConsoledbname, OracleOraDb20g_home1TNSListener and OracleServicedbname
7. I have rebooted the client computers, and the file server.
8. I don't see any errors in event logs, both on file server, client computer and database-server.
9. When I press down the link Listener, I get Metric Collection Error, which means I might not access it?
10. The only alert I find is that filesystem D: only has 15.62% available space.
They have been using the database for a very long time without any trouble, and suddenly boom.What do I do? How do I check things?

Is there any ora file that I should change or update to be able to use sqlldr from client to load data in the server.

I have toad on my machine and it connects to oracle fine using TNS but when I open sqlplus via start, i gives me a TNS Protocol error ORA-12560. Now, when I open up cmd and login like this: sqlplus user/pass@omp1, it logs in, why doesn't it login via the sqlplus program from start menu though?
Here is my tns file: JUNCORA= (DESCRIPTION= (ADDRESS= (PROTOCOL=TCP) (HOST=105.68.14.82) (PORT=1521) ) (CONNECT_DATA= (SID=orcl) ) ) OMP1= (DESCRIPTION= (ADDRESS= (PROTOCOL=TCP) (HOST=105.1.12.190) (PORT=1521) ) (CONNECT_DATA= (SID=OMP1) ) ) OMP2= (DESCRIPTION= (ADDRESS= (PROTOCOL=TCP) (HOST=105.1.12.193) (PORT=1521) ) (CONNECT_DATA= (SID=OMP2) ) ) here is the listener file: # listener.ora Network Configuration File: C:appRpatelproduct11.2.0client_1NETWORKADMINlistener.ora# Generated by Oracle configuration tools.

I tried to change to host to OMP1 but that did not work either

I have one query on sql connection.
I have 3 database on windows server. I am using oracle 10g. I want to put the one of the DB in No archive mode, for that I have shutdown the database and then set the ORACLE_SID and try to connect through sqlplus sys/password as sysdba and run the db in mount mode and all the required stuff for put in no archive mode.
but when I set the ORACLE_SID and try to connect through sqlplus it gives me error of TNS protocol adapter error. I run this command through cmd prompt.
I resolved this error by change the directory on cmd prompt to $ORACLE_HOME/bin and then run sqlplus. it works for me but don't get the reason why its not working earlier.

I have installed a database in D drive. I want to create another database in the same machine. I tried installing the new database using DBCA. Installation was ok. I added entry in TNS file.
When i try to login to this new database from other machine, i am unable to connect to this database. I made an entry in TNS on my local machine. It says the user id /password is wrong, even though they r correct. I am using the same password to delete the database.

i installed oracle 9i release 2 on windows xp professional then i installed form 6i in different home.
i copied tnsnames.ora file from ORACLE_HOME etworkadmin to forms home NET80admin folder....
Once i installed both i can see in the PATH variable both homes then bin directory....
ORACLE_HOME/bin
FORMS_HOME/bin
in these two locations you can find sqlplus.exe file, when i try to login from the command prompt like below
sqlplus "/as sysdba"
it is not going, instead it is coming to command prompt... if i remove FORMS_HOME/bin from the PATH variable i can able to do that...just keep this problem aside.When i try to connect oracle from the forms it is giving error like "ORA-12222 TNS no such protocol adapter...."

I have oracle forms builder and reports builder 10g installed on my computer. And it is working fine and connected to database properly.
Now I need to work in reports 6i and I installed that without error. I replaced the TNSNames.ora(The same i used for reports 10g) file with my database connections. But When I connect to the database i got the following error.
REP-0501:Unable to connect to the specified database
ORA-12222: TNS : no such protocol adapter
I created a environment variable for TNS_ADMIN in the system variable section as C:Ora10gdsNETWORKADMIN.
But still i am getting the same error while connecting to the database.
Should I not install the 6i while there is reports 10g already exists in my machine?
