"ORA-12222 TNS no such protocol adapter" When running Forms after installing Portal

We have a Forms 6i (web) application running on 9iAS. This worked fine. But after installing Portal on the same 9iAS, we got the following error when starting the WebForms application:
ORA-12222 TNS no such protocol adapter
Who knows a solution?
Configuration
9IAS v1.0.2.2
8.1.7
Form 6i Patch 10
Windows NT
Best regards,
Harm van Zoest

This is s SQLNET error.
You can search for it on OTN using the search button.
IT usually means that the tnsnames.ora file was changed. Or that you are now using another tnsnames.ora.

ORA-12222: TNS:no such protocol adapter

This is not a repository problem, but it happened when I tried to install the repos.
I get this message whenever I try to connect to the database using sqlplus from the orecle_home where I installed the repository or the repos. admin-utility.
I have tried both to use TNS_ADMIN and not, but the error is the same in both cases.
When I use Net8 assistant to make a tns and test the connection it works fine.
I can connect to the database with sqlplus from my 817-oracle_home.
I just tried to install the protocol-adapters manually, but it doesn't help.
Does anybody know what to do?
Arne.

Dear OTN,
I've got the same problem!
After I upgraded Designer 6i Rel2 to 6i Rel3
SQL Plus 8.0 returns ORA-12222 Error, "The protocol adapter requested (by way of the "(PROTOCOL=..)"
keyword-value pair in a TNS address) is unknown. If the supplied address
is typographically correct then the protocol adaptor is not installed.
Action: Install the protocol adapter or correct typographically error,
as appropriate. Note: if the supplied address was derived from
resolving the service name, check the address in the appropriate file
(TNSNAMES.ORA, LISTENER.ORA or TNSNET.ORA)."
I'm not novice and checked quite a few times all required files and also tried NET EASY CONFIG and so on. It doesn't work.
Please, help me with the settings! It should be beneficial to all!

Patch6: paradox-ORA 12222 TNS : no such protocol adopter

getting a ORA 12222 TNS : no such protocol adopter found
after installing patch 6 over existing oracle 9i AS 1.0.2.0.0
and forms 6i and reports 6i server,when we are running the test form with all the settings required for running forms as servlets tesst forms is coming successfully.But when with the same parameter we are running our form which makes databse connection gives the above ORA error 12222.
to ensure that it is not a protocol adapter problem we remove one line
;serverURL= ---- this line is commented-----
serverURL=/servlet/oracle.forms.servlet.ListenerServlet
and put instead
serverURL=
;serverURL=/servlet/oracle.forms.servlet.ListenerServlet ---this line is commented ----
After replacing again we tried to run the test.fmx as well as our form.Both were running successfully.
Since this one line change made Listener Servlet inactive and forms listerner as active component.
looking at the above situation we came to conclusion that it should not be a TNS protocol adaptor probel. so there must be either some problem with the configuration or some probelem with the patch 6 itself.
(we would like to mention that earlier we did same thing with patch 5 and getting error FRM-92100.This error was resolved when we used patch 6 with one additional line
in formsweb.cfg
as "networkRetries=30" )
we are using windows 2000
null

A few more facts..
while installing we had done a custom install for patch 6 .Druing this a error came up as
a wrtie error while trying to copy NLSRTL33.DLL while installing server patch component during custom install.
does anyone out there know .. what this DLL is for.

Designer6i - can't connect database TNS:no such protocol adapter

Cannot connect to database with Repository Administration Utility.
I have installed Oracle8i Enterprise Edition Release 2 on my WindowsNT in one oracle_home (ora8i) and Designer 6i in the same machine in another oracle_home (orades which is DEFAULT_HOME).
Installation is successful. I have set up the tnsnames.ora file in the directory d:\orades\net80\admin. I have also set the registry variables \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\TNS_ADMIN
and
\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\Home1\TNS_ADMIN
to d:\orades\net80\admin as per Installation Guide.
From ora8i->DatabaseAdministration->DBA Studio I can connect to the database using the service string in the above tnsnames.ora file.
But it fails from OracleRepository6i-> RepositoryAdministrationUtility with an error of ORA-12222: TNS:no such protocol.
The TCP network protocol is installed for Designer6i as the folder "tnsapi" exists in orades\net80.
Can anyone please point out what is wrong and help? thanks

Hi PAUL,
I think you first install designer and then Oracle.

TNS-12538: TNS:no such protocol adapter, and install MS loopback adapter

Hello,
I am trying to install oracleAS Infrastructure and portal on my windows xp pc. (Oracle Application Server 10g Release 2 (10.1.2)
At some point of the installation for Internet Directory Configuration Assistant, there is an error:

===========================================================
After did some searching, I find I may need to install MS loopback adapter.
So I followed http://support.microsoft.com/kb/839013 to install the MS Loopback adapter.
After I installed, When I open the Network Connetcions, I found there are two local area connetcions. One of then called local area connection 2, and it's MS loopback adapter. I got a warning for local area connection 2, it says that my pc does not have a IP address assigned, and its status is : limited or no connectivity .
I tried to repair to establish the full connection by clicking on the repair button, but the process is failed.
I also tried to run command: tnsping orcl ( orcl is my database service name ), after installed the loopback adapter.
tnsping orcl, still got this error:

Q2. Do I have to install MS Loopback adapter for installing Oracle Application Server 10g Release 2 (10.1.2)?
I don't have a fixed IP, however my IP is seldom changed. And I'm ok with 127.0.0.1
Any suggestion ?

Would probably have to see your listener.ora to know for sure but two things I would look for: AFAIK you can use either tcp or udp for the PROTOCOL= statement in the listener.ora, the Oracle Listener listens on port 1521 so you should add port 1521 to your SERVICES file in the /etc directory. See if either of those help any..

However, before finishing configured listener, something warn me as popup message.
"The information provided for this listener is currently in use by other software on this computer.

I'm so doubt, what wrong with my listener. Why did oracle warn me that my listener was conflict with another. Although, there was no listener.ora at that time. ?????

Hi,
Can you ping the schema2 which is another DB or can you connect to schema2 DB with the service which you have used for DB link.
Check that first functioning correct or not.

*URGENT* Forms 6i on XP - "no such protocol adapter" problem

Hello,
I seem to have run into a common problem but mine has a twist.
I have a laptop with Windows XP that I have installed Oracle 8.1.7.3.0 on. That works fine.
I have a project that has me connected to Oracle O.com network. I can connect fine to that using my initial Oracle installation.
I needed to install Oracle 6i and ran into a few problems, but found recommended work arounds which included me installing it in a seperate directory as Windows 95 or windows 98. I installed it in C:/oracle/developer. I can open existing forms to work on them.
What I can't do is connect to my O.com connection using the Developer or the Sqlplus 8.0 version that is included with it.
Per this website http://metalink.oracle.com/oracleinstall/oracle8i/windows.html#MSfive
I have run through the net80 configuration process.
I have copied my working tnsnames.ora file to all possible locations that the developer version would pick up (including of course c:\oracle\developer\net80\admin).
I have changed the required sqlnet.ora file to sqlnet.old.
I rebooted.
The listener and database start on their own, so I don't have to start them from the dos prompt.
Any attempt to connect to the O.com or my local database using the Developer sqlplus or Developer itself results in the message - "ERROR: ORA-12222: TNS:no such protocol adapter".
If I try to connect to some made up database name, I get a "could not resolve service name" message. So I can tell that it least recognizes my database names defined in the tnsname.ora file.
If anyone has installed Forms 6i on XP and ran into similar problems and fixed them, or if anyone has any clue as to what I need to do to fix this, I'll be immensely grateful.
Thanks.
Kurt

It occurs to me that perhaps I need to install a second version of the listener, specifically for my forms environment. Is this the case?
Thanks again.

No such protocol adapter

When i connect to oracle8i from form builder, connection failed and giving an error message 'no such protocol adapter'(error code- ora-12222). I checked the tnsname.ora and listenr.ora file but could not find out any mistake.
Can u pls any one gving the solution of the error?

No. Oracle database(8.1.6) and D2K(6i) in the same machine. OS is windows NT Server. I can connect sql plus from database SQL but cant connect from developer SQL.
During the service name configuration Test Connection shows OK. (Successfully connected).
Pls give the suggestion how to connect to database from developer.
Thanks
Sanaul.

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

Hi, I installed Oracle developer suite to use for Oracle forms but am getting "ORA-12560: TNS:protocol adapter error" when trying to run a form. The database is running locally on my PC.
I've run the command line to see if hostname matches up with the "HOST= " in the ".../network/admin/listener.ora " file match, they do. What can I try next? I did have Oracle 10gXE installed, which I have now removed. I'm including my tnsnames and listener file content:
# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
LISTENER_ORCL =

LISTENER =

Thanks in advance for any help!

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.

ORA-12560: TNS Protocol adapter error after full database restore.

Good afternoon,
Following the steps given in page 9-32 of the 2 Day DBA document, after doing a full database restore, the home page shows:
NOTE: all of the output shown in this post is obtained directly from the host not a client. AND all using ENTERPRISE MANAGER.
1. The database instance is down
2. The listener is up
3. Agent Connection to Instance has status of Failed, followed by ORA12505: TNS: listener does not currently know of SID in connect descriptor (DBD ERROR: OCIServerAttach)
When I try to connect as sysdba using SQL Plus, I get the output shown below:

I don't know what else I could have done given the behavior of the service.You can avoid problems like this in the future by avoiding Windows & using any approved *NIX Operating System.
No such "service" or daemon exist on any *NIX OS.
