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.

This error generally occurs when you listener at server is not working properly or at client you sqlnet.ora,tnsnames.ora (if using local names) file is not configured properly check both the files

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 =

(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

$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?

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):

Using the Dos command window, I stopped and started the listener (lsnrctl stop/start and its current status is (in french!!):

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 :
I set ORACLE_SID=SCFOXD
a) lsnrctl status : all seems ok.
b) tnsping SCFOXD : seems ok.
c) tnsping80 SCFOXD : brings this error:

Any other suggestion?

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)
)

I installed a windows nt version on windows 95 and cannot log in. I am getting the error ORA-12203 TNSnames. Help anyone?
thanks

Hi,
If you are using Sqlplus on the same machine in which you have the DB, you can run it in two ways :
- Specifying only username and password : in this case you have to set ORACLE_HOME and ORACLE_SID environment variables. ORACLE_HOME should be already defined in the registry, so you should have to set only ORACLE_SID = <your SID>
- Specifying username,password and connection string : here you have to configure an alias in the TNSNAMES.ora file to point to your DB : you can do this using NET MANAGER or NET EASY CONFIGURATION (I don't use often Windows systems, so I don't remember exactly....)
If you are using a Client, the second way is needed.
Then you have to check that the listener is running on the Server. Check the listener service, it has to be active. If so, from a DOS Window try :
LSNRCTL stop
LSNRCTL start
This stop and restart the listene

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.

Oracle8 Error Message ora-12203 TNS unable to connect to destination

I am receiving error message 12203 TNS unable to connect to
destination when trying to connect to the database. Also notice
Oracle TNSListener80 isn't starting properly. I start the
service and close services and open up again and the service is
not running. Any idea's would be greatly appreciated.

Please try to start the listener via dosbox:
lsnrctl80 start
Maybe you have to set environment variables before that:
set ORACLE_HOME =
set ORACLE_SID =
If the listener start correct then try from client:
tnsping <alias>
-> ok ?
sqlplus name/password@alias
-> ok ?
If not ok, please check first if you set the hostname correctly
in listener.ora and tnsnames.ora.
Regards,
Thomas

As there are several fixes to this issue, one unique place to look for is the iptables/firewall in Redhat server. Even though EBS applications worked fine until the reboot, we looked at the iptables that was disabled using ‘service iptables stop’ but was never turned off in rc. Nonetheless, this forced the iptables to be enabled during startup and blocked the tns port.
running ‘service iptables off’ helped to fix the issue.
Also, you can confirm if this is the case by simply running telnet dbserver port number . If it doesn’t connect, above fix is valid.
