// *Cause: Invalid address specified or destination is not listening.
// This error can also occur because of underlying network or network
// transport problems.
// *Action: Verify that the net service name you entered was correct.
// Verify that the ADDRESS portion of the connect descriptor which
// corresponds to the net service name is correct. Ensure that the
// destination process (for example the listener) is running at the

$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

You have to enter the database you want to connect to in the tnsnames.ora file.

Error Message :- ORA-12203 TNS : Unable to connect to destination

Hi,
I am trying to install Oracle 8i and oracle Forms and reports on my personal system for prectise purpose,
I have window XP on my system and I installed Oracle Forms & Reports first on my system in C: drive,
then I installed Oracle 8i(sql, pl/sql) in D: drive on my system, both installed successfully
but whenever I am trying to connect oracle(sql)
with scott/tiger then it is showing below error message and unable to connect with oracle(sql)
ORA-12203 TNS : Unable to connect to destination.
Please suggest how can I solve that problem.

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.

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.

Thomas

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.

Hi, All
I installed Oracle 8i and oracle form 6i.
The installation was successful.
It is installed in separate drive.
I can't connect to the forms
the error is
ORA-12203 :TNS :Unable to connect to the destination
please help me..

1) Verify that you have entered the net service name you wish to reach correctly.
2) Verify that the net service name ADDRESS parameters in the connect
descriptor of your TNSNAMES.ORA file are correct.
3) Verify that your TNSNAMES.ORA file is stored in the correct directory.
4) Verify that the listener on the remote node has started and is running. If not,
start the listener by using the Listener Control Utility.
5) If you are connecting from a login box, verify that you are not placing an "@"
symbol before your connect net service name.

Hi,
yes i can get to my database through the sqlplus ... i can also connect to the same database from a 9ias installation on another server and running my application.
what we trying to do now is combine the 9ias and the rdbms on one single server.
When i look at my trace files from both 9ias installation the first number of lines are equal till i get the following from the 9ias which goes wrongly
nricall: Got routable address information.
nricall: Making call with following address information: (DESCRIPTION=(CONNECT_DATA=(SERVICE_NAME=mp5prod)(CID=(PROGRAM=e:\Dev6i\bin\ifweb60.exe)(HOST=OVDAME-MP502)(USER=mp5psv1)))(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=1521))).

the other server gives a succesful nscall
the hostname is ofcourse entered correctly in the tnsnames but have been removed in this post.

Ora-12203 TNS unable to connect ot destination

Good Day.
My boss handed me a 8.0.5 database running on win2k3R2, I'm encountering the ora-12203 error, I restarted the service and tns listener of oracle and it worked fine but what's bothering me is before I didn't need to restart the service or tns listener. When I reboot the server a windows error pops out "STRTDB80.EXE" encountered an error/problem, is this related? Does anyone have any ideas how to fix this?
And in 8.0.5, how do you enable archive logs? isn't it the same as in 9i or 8.1.7?
Please help.
Thanks and Best Regards
Dexter Kwan

8.0.5 is not supported for this platform. If you are successful to start it and peform some tasks on it it'll be ok, but there is no guarantee it will work smoothly
I suggest you to install it on a winNT 4.0 Platform, otherwise, you may be walking on a mine field.
If you want to configure archivelog, it is quite the same as in 8i, just make sure you set the log_archive_dest parameter. You may set also the log_archive_duplex_dest parameter and the log_archive_min_succeed_dest.

how connect oracel with report by useing configuration assistant can you give me idea
thanking you

The database and the Oracle software are on the same computer, so I don't have to use remote connection. I've checked the listener and the database name is on the list (protocol: IPC, name: ORCL). On the other hand the name of the database is the default name (ORCL), and when I first create the database (with the Database Assistant tool) I've checked the option "Add to the listner". I think that is enough to be sure that the db name is on the list. But still I have the error. Moreover, when i start the service Oracle Tnslistener80 (is this the service, right?) it starts correctly, but after one minute it automatically stop.
Thank you for the reply

TNS-12203 TNS: unable to connect to the destination

I want to archive the database, but when i log on to the backup manager with user = internal, I get the error TNS-12203 TNS: unable to connect to destination.
is there other way to archive the database?

I'm not sure what do you mean by archive the database. But usually message "TNS-12203 TNS: unable to connect to destination" means your target database was listened on different port.
Verify your tnsnames.ora on the backup manager server to see if the port is the same as that in tnsnames.ora on the target database server. The default is 1521 but it could be 1522, 1523 etc...
Good luck
