ORA-12560 TNS protocol adapter error--URGENT HELP!

To Experts:
I tried to log in the SQL by using the username: system, manager for password. however, it gave me the message:
ORA-12560 TNS protocol adapter error.
I am using Oracle 9i and Developer 6 in Wins XP environment.
Thank you much!

Yes,Thank you very much.I am ok to invoke these commands.
the listener started already.The listener name is just LISTENER.But i still can't login sql plus.Help me on.
hi,Mr sb92075
Do you use what kind of messenger?If we can communicate on messenger,it will facilitate solving my problem I think.I don't mean to disrespect you but I just want to overcome the problem very quickly.
with best regards,
Ian Su
Can I know very clearly?
what are the things(eg dbname,username,protocol I don't know exactly just guessing)needed to connect to the database?
I already installed oracle developer suite 10 and oracle 10g xe database server.
I can't login to sqlplus and what are the things i need to check to get connected to the database from sqlplus?
I appreciate your help and need somebody help.

Error ORA-12560:TNS:protocol adapter error - on client

dear frnds,
I am try to install oracle 11g to my client iam getting error
ORA-12560:TNS:protocol adapter error
pls help me out
thanx in advance

Most likely reason for TNS Protocol adapter error is....you must have older client FIRST in your path.
You 11g binaries are not kicking in, cuz...you must have 10g or similar/older binaries first in your PATH ( in windows )
In windoz...in cmd window...
set ORACLE_SID=xxxx
set ORACLE_HOME= to your 11g home
cd %ORACLE_HOME%\bin OR set PATH=%ORACLE_HOME%\bin;%PATH%
Then your sqlplus etc..
This time you should not be getting the protocol error.
Let us know whether this solved your problem

Help: Error message "ORA-12560 TNS:Protocol Adapter Error "

I tried to install Oracle 8i EE version 8.1.7 on Windows 2000. Everything is OK until the installation proceeded to installing "Oracle Database Configuration Assistant". At that point, I got an error message "ORA-12560 TNS:Protocol Adapter Error (network not loaded)". I looked up the error message. The cause of the error said: "This error occurs when the SQL*Net driver cannot find the JSB driver because you may have either forgotten to load the JSB driver (for instance MFTP) or used an incorrect TCP_VENDOR key (for example, TCP_VENDOR=NOVLWP).". And the suggested action said: "Load the JSB driver or use the correct TCP_VENDOR key.". I am using a standalone PC with Windows 2000 at home, and the PC does not connect to any network(except that I can dialup to internet via modem). What should I do? I can't understand the error message. Any expert to help me overcome the error?

Help: ORA-12560: TNS:protocol adapter error

I created a new database and afterwards my established TNS connection to my starter database was lost. Now I cant get it to work. I tired deleting the new database I created, but my old connection with my starter db still does not work. When I test the connection using the NET 8 assistant I get the following error: ORA-12560: TNS:protocol adapter error.
Im fairly new to Oracle8i and Ive posted numerous threads elsewhere concerning my problem but so far I havent gotten a solution. Any ideas?
Thanks, Andrew

Edwin,
1. I can ping my server.
2. I reinstalled Oracle8i entirely on the server I still could not connect.
3. I installed Oracle8i client on a totally new client I still could not connect.
On thing though, when I de-installed all Oracle products and then reinstalled Oracle, some of my settings from the previous install still existed. Ex: When I opened Net 8 Assistant some of my Net Service Names remained from the previous install.
Three things I think I can rule out as causes:
a) It seems really significant that from the server I can successfully connect through the TNS connection. And this is using the exact same TNANAMES.ORA file that is on my client machine. This leads me to believe that my TNSNAMES.ORA file is not the cause of the problem.
b) Also the fact that the new client install (3) didnt work makes me think for sure that it is not the client.
c) When I open SQL Plus on the server I type ORACLE4 for the host string and I get right in. This leads me to believe that the instance and database can be ruled out as possible causes.
In the Oracle Client Net8 Profile section I set tracing to on. I am posting the results. Also FYI: I am the only person that has been working with Oracle on the server. Any ideas??? Andrew

Gives ORA-12560: TNS: protocol adapter error when installing oracle 10g

I tried to install oracle 10g r2 in server 2008. but it gives ORA-12560: TNS: protocol adapter error when installing. how I can fix this issue??? please help me ASAP. because its urgent.
thanks in advance.
chamara

Welcome to the forums !
Pl indicate which version of 10g you are installing and on which version of Win 2008. Neither 10gR1 nor 10gR2 are certified to be installed on Win 2008 R1, AFAIK.
For 10gR2, only 10.2.0.5 is certified for Win 2008 R2 - see MOS Doc 1173433.1 (How to Install Oracle 10.2.0.5 on MS Windows 7 / Windows 2008R2)
Also see MOS Doc 740926.1 (Where can I find the Database / Client software to download for Microsoft Vista, or Windows 2008R1?).
Both 10gR1 and 10gR2 are now in extended support - is there a reason you are not using 11gR2 ?

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.

Tarisa.

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>.

ORA-12560: TNS:protocol adapter error in Oracle Forms...

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.

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.

ORA-12560 TNS:Protocol Adapter Error and ORA-12557 Error

Hello ,
I have installed Oracle 11.2.0 64 bit database on my Windows 7 ( Home Premium) PC which is also 64 bit. I installed it because I am trying to setup Informatica. Later, I learnt that informatica is 32 bit and can not communicate to Oracle 11.2.0 64 bit database. So after digging through solutions, someone mentioned that I need to install Oracle 11g client 32bit.
I have installed 11g client software successfully now. Here is problem though :
When I launch SQL-Plus from 11g database , it works fine. However I launch SQL-Plus from 32bit client it gives me error as :
Ora-12560 :TNS: Protocol Adapter Error.
So I have been trying to resolve this error. I saw that this question has been posted many many times and have tried many thing as listed below :
1. copy tnsnames.ora from database ( dbhome_1) to client installation ( client_1 ) under ..\network\admin\ --- Didn't work.
2. Set $ORACLE_HOME and $ORACLE_SID environment variable.
Here is interesting fact - If I set $ORACLE_HOME to database path and not client path error changes to :
ORA-12557 TNS: Protocol adapter not loadable.
If I keep $ORACLE_HOME as client path then I get same error as earlier ORA-12560.
3. I have also tried changing $PATH variable. I did set to path containing only database installation, only client installation, both database and client installation with database installation appearing first
But all of these haven't worked.
Can anyone please suggest what I am missing and any further things I could try ?
Thank you in advance !

Thank you in advance !unfortunately, we need to know exactly how you tried to connect with sqlplus when it "worked" and when it "didn't work". The key to the reported error messages is highly dependent on the environment settings AND the specification of the connect string. A copy and paste of the entire command line session would be most helpful.
But again, running on any 'home' edition of windows is not supported.

ORA-12560 "TNS protocol adapter error":Win2k+Oracle8i_32bit.Helplessly struggling.

Hi Oracle Guru's,
Please save my life from this typical yet known problem.
I got an old backup on my tapes about 3 years older. I have windows server 2k where I have an access remotely through RDP(Citrix-CuraStore).
I installed oracle8i 32 bit on Windows 2k though it got stuck at the end where it installs optional tools(like Net8i assistant), so i closed the installation session, Because I could see Net8i assistant,dbca etc was installed on machine.
I checked my services, found it had started the Listerner8i service.
To create a database, I tried to happen it through DBCA...but unfortunately it gave error(ORA-12560 "TNS protocol adapter error"), I ignored it ...but it didnt move to next step...completely stuck up..So closed the session.
I tried with ORADIM to create service, It did happen, services for database was created, I setup the environment(SID,HOME,PATH) etc.
When I login with sqlplus , it gives again the same error(ORA-12560 "TNS protocol adapter error"), I tried many things like TCP/IP traffing disabling etc..Nothing worked.
Can some one please help me and give me some out of box solution..I shall be really really thankful to them.
Regards,

Sorry, If I missed to update you back..I apologize.
