I know this error and solved it before but I forgot how!
So how to solve it Plz?

Regd ORA-12560 Protocol Adapter Error

Hi Firends,
I am new to Oracle.I just installed oracle 8i Personal Edition on Windows 2000.
Now I want to use SQL Plus but it is promting me for username, password and Host String.
I typed Scott,Tiger for USername and for Password but I don't know what to type for the Host String. It says "ERROR ORA:12560 TNS:Protocol Adapter" and then it kick me off. Could anyone tell me how to get into SQL*Plus?
Thanks
Peru

I don't know the solution.
This is the forum for a specific Oracle 10g product called "Instant Client".
If you post your question to the Installation forum at
http://www.oracle.com/forums/forum.jsp?forum=64
you may find someone who knows the answer.

[TNS-12560: Protocol Adapter Error] after every 48 Hours

Dear All,
Our company encountered a very strange Oracle database issue, here is the details:
Environment
1. Dell 2950 Server with Windows Server 2003, Oracle 9i 9.2.0.1 and WebLogic Platform Server 8.1 SP3 installed;
2. Two databases on the Oracle, one is called FAX and it is a schema located in the original DB database; another one is called EIP, it is a new database created by IT staff;
3. Two applications installed on this server, the first one is a Visual C++ developed Avaya Call Routing system (BCCS), this system will query data from the EIP database; Another one is a WebLogic and JAVA based system (EIP), users access this system by using IE at client computer and this system also uses the EIP database;
4. We have a standalone fax-out server with faxboard installed and used to send fax, this server uses the FAX database;
Issue
1. Before Jun.6, everything is OK;
2. At Jun.6 night, we installed two new applications on two new server, these applications will read and write data to the EIP database via network;
3. Jun.9 12:30, we found the BCCS cannot connect to the database, error message is [TNS-12560: Protocol Adapter Error], we checked and found all Oracle's services are running properly including the TNSListener;
4. We reboot the server and then everything is OK;
5. Jun.12 10:41, Jun.14 12:46 and Jun.16 20:51, same issue occurred again, we simply reboot the server and everything is OK
It is very interesting that we found the issue always occur after 48~55 hours we reboot the server, but cannot find more useful information; there is also no failed information in the Oracle alert log.
Please share some ideas with me, thanks a lot.

Thanks for reply. Answer to your questions:
1. This issue occurs on application which were installed on the computer with Oracle installed, and there is no firewall on this computer, so I believe that it is not related network.
2. Please let me know how to check the error stack and turn on tracing.
3. ORA file info:

ORA-12564 Protocol Adapter Error -- ON Windows NT platform

I have installed 9iAS and Oracle 816 on a server as per instructions. But i started the install CD of 9iAS and after the reboot installed the 816 and 9iAS. I am able to connect to the database and create a DAD but when i try logging into the database from a client machine i get the above error ORA-12564 Protocol Adapter Error. Tnsping to Db and Ping to server from client machine respond with OK msgs. But SQLPLUS will not connect and returns above error.
We are trying to test 9iAS and perform enhancement tests to the application on 816, but are unable to connect from client machines. Any help in this matter would be highly appreciated. Thanks.

Are your oracle services logging on as localhost? cause if they
are that may be your problem. change the log on user to your
local administrator with their password (i.e.
administrator/******). Oracle DB and the other services have a
problem starting up with the localhost. they appear to startup
but don't actually startup.

Tns-12560 protocol adapter error linux

I m running two independent oracle 11g on red hat 5 in vmware workstation 7 which is sitting on window xp where i m running 10g.
I was facing a lot of networking when using tnsping. during my search i found that SUlinux and firewall was on which i turned off.
My problem solved.
My question is Whether it is feasible in industrial environment to turn off the Firewall and security of Linux.
My second problem is:
I did everything using orapwd on oracle 11g on red hat. .
but i m getting the same result
select * from v$pwfile_users;

My question is Whether it is feasible in industrial environment to turn off the Firewall and security of Linux.When you say "security of linux" are you referring to SELinux? You can turn it off, or set it to a less restrictive mode. As for the firewall, there is no need to turn it off, just configure it correctly.

We have no way of knowing exactly what "everything using orapwd" means on your system. You are asking us to explain something we cannot see.

Does anyone have any ideas what else I can check. I'm a Unix person, not a Windows person, which is making it even more complicated. If I was on Unix, I'd just blow everything away and start again from scratch, but since I'm not sure how to remove all traces from the registry, etc., I don't want to try that on this machine. There was already one other database created, but it's not goign to be used.
Any help would be greatly appreciated.
regards,
Tarisa.

hi,
thanks for the info. the problem, as it turns out, was that I was connected to the db server via a terminal service (Microsoft Management Console), which for some reason caused probelms with TNS. After I connected directly to the machine using VNC, I was able to create the database with no problems. strange but true.
regards,
Tarisa.

Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.

ORA-12560 TNS protocol Adapter error in 11g (11.1.0.6)

Hello All,
I have Oracle 11g installed on my machine and when i tried to log in to sql plus i got the error below:
ORA-12560 TNS protocol Adapter error
By setting the ORACLE_SID = orcl by browsing to the bin directory of Oracle Installation the above error disappaears and i am able to log in from sql plus.
My intention is to create a db backup for which i am trying to use the exp command...this time the same error appears.
Also the solution of setting the ORACLE_SID is cumbersome..everytimt i want to use sql plus i need to go in and set the ORACLE_SID.
Can anybody please help me out find a good solution for this?
Any help would be appreciated friends.....
Thanks in Advance!!!!!
Regards.
Alicia

Also the solution of setting the ORACLE_SID is cumbersome..everytimt i want to use sql plus i need to go in and set the ORACLE_SID.
Can anybody please help me out find a good solution for this?The solution depends on your (not specified) operating system...
Anyway, if you have more than one database it's normal that you have to set ORACLE_SID, if not how can Oracle know which database you want to access to ?
You can create batch files, one per database, or you can use connection strings, e.g. sqlplus username/password@<DB>.

Of course you found another one. Each .and every Oracle database client home (such as developer, app server) has one.
Don't just change the port - the tnsnames.ora in the dev home does not point to a database service. It only points to an extproc [external procedure called by a database]. You need to put a database service entry into that file similar to the one in the database home. (Easiest solution - copy the tnsnames.ora from db home ... after you've made a backup)
And please don't tell me you are using Developer 6i - a simple Google search would verify that the networking is incompatible.

How to solve ORA-12560:TNS:protocol adapter error?

I'm trying to use sqlplus on Windows 2008 R2 which is installed on VirtualBox to access an Oracle 11gR2 database on Red Hat Linux.
I'm sure that the database on Red Hat Linux is up and tnsnames.ora is a copy from another machine which is used by another application to connect to the same Oracle database.
When I run sqlplus, I got the ORA-12560: TNS:protocol adapter error.
sqlnet.ora
SQLNET.AUTHENTICATION_SERVICES = (NTS)
Both sqlnet.ora and tnsnames.ora are located in c:\app\administrator\product\11.2.0\client64\network\admin folder.
The registry ORACL_HOME has c:\app\administrator\product\11.2.0\client64.
echo %ORACLE_HOME% incommand window returns %ORACLE_HOME%
echo %ORACL_SID% in command window returns %ORACLE_SID%
If I set ORACLE_HOME to another folder, I will get the following error:
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
So, I believe the ORACLE_HOME in registry has the correct value.
I have also tried set ORACLE_SID to the service name listed in tnsnames.ora but sqlplus still returns the ORA-12560:TNS:protocol adapter error.
For unknown reason, the value of ORACLE_HOME and ORACLE_SID I set by using set command will not persist after I close the command window that I set the values.

It make NO sense do to as above when attempting to connect to Oracle DB on *NIX
which knows NOTHING about NTS Authentication.
SQLNET.AUTHENTICATION_SERVICES = (NONE)
or just remove the line or whole file.
Also need to be sure that ipchains is disabled on *NIX system

Step 1 - from a command line on the database machine, enter 'lsnrctl status' and report the output
Step 2 - display the contents of the %ORACLE_HOME%\network\admin\tnsnames.ora file on the machine running sqlplus.
These are the first two stepo, whether on the database machine or in a traditional client-server configuration.

Urgent!!! ERROR: ORA-12560 TNS: protocol adapter error

Recently we tried to install a new product with a new dataabse instance. Since doing this SQLPLUS replies with:
ERROR: ORA-12560
TNS: protocol adapter error
I have looked at my tnsnames.ora and listener.ora and everything looks fine. I am hoping someone here can shed some light on this for me... Is it possible something got corrupted?
Here is my file settings...
