ORA-12203

I want to confirm that I can make a connection beetween Java and my database. (weblogic 4.5.1) I get the message ERROR ORA-12203. Who can help

I'm not sure if it's related, but I had that problem under Oracle 8e ...
If the database is local, you shouldn't need to specify the service name (as long as the database instance is running). Otherwise I think there needs to be an entry for it in TNSNAMES.ORA. You can create one of these using Net 8 Easy Config.
As I said, I was working on a different version (I'm currently downloading 8i) but hopefully the same ideas apply.

ORA-12203 while calling a form from external procedure

Hi
I am using oracle 10g 10.2.0.3.0 database with forms 6i. We have created a database procedure , which makes a call to external procedure(C program). Now this external procedure creates a process and process is creating a call to form.
We have checked through the process explorer in the server, process is getting created successfully, but doesn't executed. We tried to start the process manually, it is throwing ora-12203: TNS unable to connect to destination.
We are able to connect the database from form's runtime. but if this runtime is executed from a process which is created by external procedure, it is throwing ora-12203.
Any idea?

check tnsnames and listener files.verify the host and the port

ORA-12203 error in Forms6i, after installing 10g local DB

Hello,
I have a configuration with multiples Oracle_Homes as I use Disco R4, Forms6i, Forms 10g, and sqlplus. I had no problem when I used a local 9i DB. All worked fine.
When I had the 9i DB, I decided to set a TNS_ADMIN variable and only use one version of SQLNET.ORA and TNSNAMES.ORA. All was fine !
Recently, I have decided to install a brand new 10gR2 DB, and get rid off my 9i DB.
Since then, only the 10g tools work fine... and I cannot connect anymore to any of my Forms6i or Disco. BIG Problem !!!
The error is always the same : ORA-12203: TNS:unable to connect to destinationI have made many different tries for fixing this issue...but I have no clue, and I would like some advices from you.
Here are the details of the variables and files (after all my modifications):
- My 10DB is located under OracleHome DB10g_OH (c:\10g\DB)
- My Forms6i is located under OracleHome DEFAULT_HOME (c:\oraNT)
- I created environment variables
ORACLE_SID=SCFOXD
TWO_TASK=SCFOXD
and
PATH= C:\10g\DB\bin;C:\orant\bin; ....
I currently put the same version of listener.ora, sqlnet.ora and tnsnames.ora in both directories (C:\orant\NET80\ADMIN and C:\10g\DB\NETWORK\ADMIN):

Looking at the listerner status, all seems fine, except the status UNKNOWN of the DB... I have no idea why it is that, as I can successfully connect it using the 10g tools (sqlplus/forms10g)
To go further, I can reproduce the same error (like with Forms6i) when I use the DOS command window, when I run plus80.
Anyway, I am sure there is something I missed to do... but, I am really stuck, and I would like to get some advices in order to solve my issue.
Thanks,
Olivier

Thanks for your quick reply.
1) forms 6i version is = 6.0.8.23.2
2) in the DOS box, here is what I get :

Any other suggestion?

the ip address of the client machine has been allowed thr our firewalls and been allowed to use sqlnet on oracle port 1521
following setting have also been done

At O/S level we have given oracle_home for 9i access (read, modify execute ..etc) to all sub-folders under e:\orant\ora9i

Hi Paul
we have 2 external machine which have been given access thr our firewalls
our database is in Wales and the machines are in england.
everything is ok on the server as i have checked the settings which i could know of
All these machines are on same N3 network , the 2 client machines have DNSlookup set which goes thr all the necessary firewalls and when the following command is run on client machine it can see the server
c:\> nslookup < machine_name >
the access to our database is given thr range of ip address as we dont have static IP and when the above command is run it returns dynamic IP address for the database in Wales
H:\>nslookup krusty.hsw.wales.nhs.uk

SQL not connecting to Personal database - ORA-12203

I have just installed Oracle 8.1.7 Personal Edition which is required for my Graduate Database Mgmt course.
I am getting an ORA-12203 error when loging onto SQL Plus (part of the install instructions) Instructions say to leave the Host String blank. Only gives instructions for errors 27101 or 01034 and cannot seem to find a help or error index anywhere.
Please help so that I can continue or else drop the class in time to get my money back!!!!

Jana,
Your TNSNAMES.ORA file will be found in a path similar to this one:
C:\Oracle\Ora81\NETWORK\ADMIN
The file may looks similar to this:
ORA1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xx.xxx)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = ora1)
When you log on to SQL*PLUS try:
USERNAME: system
PASSWORD: manager
HOSTNAME: (leave blank)
If you still get an error, refer to your TNSNAMES.ORA file to see what your host name should be (in my example, it is ORA1).
If you still get an error after filling in the hostname, launch server manager (C:\Oracle\Ora81\BIN\SVRMGRL.EXE), then try to start the database:
SVRMGR> CONNECT INTERNAL
SVRMGR> STARTUP
Good luck,
Emily

Ora 12203 in oracle 8i on windows 7

dear all
i have been install oracle 8i on windows 7 by using the way of right click on the EXE file and choose the compatibility with windows XP service pack2
all installation is finished very well but there is a little problem happened when i try to enter to DataBase as below
ORA - 12203 : TNS: unable to connect to the destination
please help me with this error because it is so important to still working on ORACLE 8i
thanks

Please don't mind. I didn't meant to insult you in anyways. It was your statement which did bring laugh and probably, that wasn't appropriate but I couldn't stop myself from doing so. There are numerous new features which the latest releases has offered. So saying that 8i is more reliable than the other versions is a sort of wrong statement . It may be but compared to version 8 just it was from 7.3 and the story goes on. 9i changed the way database was working. 10g, 11g took it to another levels. So your statement is actually not correct. On top of everything, 8i is long time back, desupported which means using it now is really not a good idea for a production system unless you are not an esteem customer who is still enjoying support for it from oracle. Also, you are attempting to install it on the most latest o/s which never certified 8i to run over it ( and neither it would ever will do too) so I believe, you may get errors for sure and unfortunately, no one would suggest you anything about it since the whole combo of yours is unsupported.
Now, you keep on asking about the solution to your problem . Did you read the error descripition that I posted about the error somewhere above? Have you tried the action mentioned in it? If yes, what was the result?

Import and error ora-12203

Hi,
I got this error ora-12203 (TNS:unable to connect to destination) when I was importing a table into my own schema. I don't know whether the error is related with import. My question is: when performing import, can other user login into the database?
Thanks,
Richard

Hi Richard,
The database will you to logon irrespective of what other work you are doing with whatever tool you are using. The Exceptions are :-
If the refered schema comes under certain restriction of the assigned profile.
If the database is running in RESTRICTED mode and you are not having accessibilty during this peiod.
As for your error in the import statement, check the connection you are using in the import statement.
I'm personally using import at least 10 times a week and usually come across these errors. These errors are all human errors and not bugs in the program.
Bye,
Piyush.

$In Developer Home check that TNS alias in tnsnames.ora has no errors. Are you able to connect from Sql*Plus from Developer Home, using same alias ?
Also check that the listener is running on DB machine.

Hi!
Does this happen when you are on another machine? Maybe there is a firewall present?
When you are on the machine itself, can you connect?

ERROR ORA-12203: TNS: unable to connect to destination

Hello All,
I have installed Oracle 8i and forms 6i on my computer running on Windows NT 4.0 with service pack 4.0. The order of my installation was Oracle 8i and then Forms 6i. I have also used Net8 Easy Config to configure the tnsnames.ora file. I tested the connection on the Net8 Easy Config wizzard and I got the connection successful message. However I still get the ERROR ORA-12203: TNS: unable to connect to destination message when I tried to connect from forms 6i.
I have below my tnsnames.ora file:
# C:\FORMS6I\NET80\ADMIN\TNSNAMES.ORA Configuration File:C:\forms6i\net80\admin\tnsnames.ora
# Generated by Oracle Net8 Assistant
LISTENER1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = austin)(PORT = 1521))
(CONNECT_DATA = (SID = SUN))
Rep60_AUSTIN-Forms6i,Rep60_AUSTIN-Forms6i.world=(ADDRESS=(PROTOCOL=tcp)(HOST=AUSTIN)(PORT=1949))
I have created database objects, but forms will not connect. What else should do?
Thanks for your anticipated response.

Hi
Your oracle database and forms are installed on different oracle home so when you configurate your sql net that time you are configurating only your oracle database. So for form you must be having different oracle home. you cand change thid from start/oracle inatallation products/home selecter. so change our home and run the form. and if still having problem than check for tnsnames.ora file you must be having two files and both must be having right configuration.
thanks

ORA-12203 and ORA-03106

ORA-12203 TNS:unable to connect to destination.
ORA-03106: fatal two-task communication protocol error.
Hi,
I got this error when i tried to connect to oracle10g Express
from windows 2000/XP station using oracle8 (NET80) client in the station
because my application was developed in FORMS6i/REPORTS
I would like to know if exist some incompatibility between Oracle10g Express and NET80 protocol ? (exp80, imp80, sqlplu80)
PS: When i use Sqlplus from Oracle9i/10 client the connection works fine
Thanks

I think that it is quite reasonable. Forms6i seems to work fine against newer Oracle databases like 10gR2 Enterprise Editon, Standard Edition and even Express Edition (using non-Unicode character sets).
The point is that Forms6i never worked against Unicode databases. The product is no longer under development (for some time by now) and this new functionality has been added to the newer releases like 9i and 10g.

Ora - 12203 error

Hi all
I installed oracle 9i and forms 6i on my home system. Operating system is window xp media center edition 2005. SQLl*plus working fine but when i tried to connect database from forms it is giving following error
ora-12203:tns:unable to connect destination.
Some one help me to solve this problem please.
Thanx in advance,
Ram.

Invalid TNS address supplied or destination is not listening.
This error can also occur because of underlying network transport problems.
Verify that the service name you entered on the command line was correct.
Ensure that the listener is running at the remote node and that the ADDRESS parameters specified in TNSNAMES.ORA are correct.
Finally, check that all Interchanges needed to make the connection are up and running.
Verify your tnsnames.ora entry matches the address where your listener is running. Example:
MyOwnDB =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = HostPCName)(PORT = 1521))
    (CONNECT_DATA =
      (SID = DatabaseSID)

dear friends..
it 's been for long time that i have been popped up with the iterating statement at the login time "ORA-12203: TNS:unable to connect to destination " .i slept over the issue and what i have found is that sometime we are not aware that at the time if process is started or not or whether it is started automatically or automatic.i would suggest you to make it "automatic" and prior to that make it sure if the process is already started or not.
i hope by doing this method it might help you to come out from the problem.

You should be able to log in with

You can either leave the host string blank, or use ORCL.
