Connections with TNS V1-V3

Can anyone please explain what are connections with "<NAME>@<HOSTNAME> (TNS V1-V3)". and how are they created?
thanks in advance.

Oracle 6 came with TNS version 1 aka sqlnet v1.
Oracle 7 came with TNS version 2 aka sqlnet2, you didn't need separate drivers anymore for each protocol.
Oracle 8.0 and higher came with TNS version 3 aka Net8, introducing the service_name = syntax and a new set of OCI libraries, as the protocol changed.
On Oracle7 you see 'TNS V1-V2', and somehow I seem to recall, if you use the SID= syntax in tnsnames.ora you still use the OCI7 libraries, this will show when you run trcasst on your client trace files.
You only need to be somewhat inquisitive to get to know these facts. Just a bit of peeking around is sufficient.

"Xandros" (linux flavor), shows "TNS 12203" connect with oracle server(win

I am using oracle developer 6i and from 2000 on operating system "Xandros" (linux flavor),and working properly after instalation.
Problem when i am connecting to this Machine with oracle server(windos) it shows "TNS 12203"
i want to use xendros at client side to connect with Database Server on windows nt.
Thanks

Hi,
here is the descroption of TNS 12203
oerr TNS 12203
12203, 00000, "TNS:unable to connect to destination"
// *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
// remote node.
Check if you see the database server from the client machine, and if listener is running and on which port, check tnsnames.ora on client.

Hello,
OC4J is the core component of the OracleAS, the J2EE/WebService container where you deploy your J2EE applications
So you are using OC4J when deploying your application.
Do you know what release and the type pf topology that you are using when deploying your application? (stand alone OC4J -run from java command- or a managed OracleAS run from an opmnctl command...)

Database access error: Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

Hi All,
I am using oracle 11g client library on Linux 64bit machine and trying to connect to oracle database using jdbc thin driver.
The url format what I am trying to use is:
jdbc:oracle:thin:@IP address:port:service_name
When service_name = orcl : I am able to connect with the above syntax.
But when the service_name is having . e.g service_name = orcl.177.39.45, with the above format I get the above error.
If I change the URL syntax to following, it works
jdbc:oracle:thin:@IP address:port/service_name
But both seems to be valid syntax.
So I would like to undestand the reason behind the same.
When service_name is having ".", why ":" does not work and "/" works and when the service_name is without " ." , 1st format works.
Is there any specific reason behind same?
Please let me know,
Thanks,
Aarati

Hello,
as per the suggetion, I replaced the URL in the format
URL=jdbc:oracle:thin:@15.154.47.235:1521/ORCL
original URL :
URL=jdbc:oracle:thin:@15.154.47.235:1521:ORCL
With this I was able to access the main page and was not getting database access.
But when I tried to perform some operations say list the submitted jobs, our application internally contacts Oracle database and gets the information stored in the database.
its not able to get and it throws exception.
So is there any reason behind this?

1. Is the connection url correct?
"jdbc:oracle:thin:@PLANET:1521:ORCL" is fine.
2. Is the TNS listener started?
c:\oracle\product\ora10\bin> lsnrctl status
3. Is a firewall between client and database server?
Connection url with firewall would be different.

"no ocijdbc11 in java.library.path" error when connecting a TNS database co

Hi
"no ocijdbc11 in java.library.path" error when connecting a TNS database connection
I have the same problem 'error code' when testing the connection to a database although I have an APEX db that connects without a problem.
I have re downloaded jre & SQL Developer just to ensure all files are where they should be with no luck.
I've also tried most of the suggestions in various threads.
Does anyone know what exactly causes this error?
eg; should I be looking for a file called 'ocijdbc11' & put it into the 'java.library.path' path?
Can anyone explain to a newbie at db connections what I should do?
I'm using the 'thin' client as the checkbox is clear & I don't know what path to enter into the correct file to make this work??
This is & needs to connect as a TNS connection & was working fine until recently, the only change I can think of is a move of files from the 'C' drive but I thought redownloading SQL Developer would slove this.
Thanks

When you reinstalled SQL Developer, did you install into a new directory (ie rename or delete the old directory first)?
I don't know if system setup contains directory references (which might be invalid after moving the location of SQL Developer). Does renaming your system2.1.1.64.45 directory (in C:\Documents and Settings\username\Application Data\SQL Developer) help? Note that your connections are in the connections.xml file in the o.jdeveloper.db.connection.11.1.1.2.36.55.30 subdirectory of system2.1.1.64.45 - you will either need to export connections before renaming and then import again after or copy this file to test if you can connect.
Finally, the TNS Names directory preference is just a way of telling SQL Developer where to look for the tnsnames.ora file, rather than just assuming it will pick the right one. If you go to create a new connection, do you get the right list of TNS aliases? If not, then set this preference to the directory where the right tnsnames.ora file lives.

Trouble connecting with sqlplus

I installed the "instant client" rpm files...
ORACLE_HOME=/usr/lib/oracle/10.1.0.2/client
tnsnames is located in
/usr/lib/oracle/10.1.0.2/client/tnsnames.ora
and it has the following contents
ibis8i =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ibis.[company_domain_here])(PORT = 1555))
(CONNECT_DATA = (SID = oracle))
when I try connecting with
[user]@ibis8i
Hi, I get the follwoing error
ORA-12154: TNS:could not resolve the connect identifier specified
I can't work out what the problem is :(
This same tnsnames.ora file is used on another machine on the same network and it has no problems at all (ie. the specified identifier does exist).
help would be much appreciated.

I used php4 some years ago with 8.1.7 DB.
In my php login function ORACLE_HOME was configured as
putenv("ORACLE_HOME=/ora/OraHome1");
and it worked (/ora/OraHome1 was my Oracle home).
Now I don't use php anymore, but just trying to help you, I tried to connect to a 9i DB, and got your same error. Maybe 9i and 10g need a newer php version (or oci8 version) .....

Global_name issue + connection using TNS -trouble

IPT_TEST.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.29.62.21)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = TEST)
IPT_TEST =
*(DESCRIPTION =*
*(ADDRESS_LIST =*
*(ADDRESS = (PROTOCOL = TCP)(HOST = 172.29.62.21)(PORT = 1521))*
*(CONNECT_DATA =*
*(SERVICE_NAME = TEST.IP-TECH.COM)*
Now the Global_Name of the database is
select * from global_name
TEST.IP-TECH.COM
but by SQLDeveloper I am able to connect to TEST SID. But SQLDeveloper uses JDBC connection not TNS.
But while am trying using TNS , am not being able to connect to TEST.IP-TECH.COM ,
Even while am trying to configure Net Configuration Assisstant , it is not recognising TEST.IP-TECH.COM as a valid service name.
Also, I tnspinged. That is working. :(

Oh very Sorry, actually I thought I went angry probably my question is so easy.
Yes I know that SQL Server can also use TNS.But currently, it's not connecting by TNS, it's using the JDBC connection
ORA-12154 error is the one I am getting.
Ok, then after I login in my onsite server will ping the service name "TEST" and will let you know the result.
My senior told me to check in the serve
Select * from gv$active_services;
I will request my onsite counterpart to check that also.You are free to rant what ever nonsense you believe.
ORA-12154 mean the lookup on the client failed & has NOTHING to do with anything on DB Server
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.
// *Action:
//   - If you are using local naming (TNSNAMES.ORA file):
//      - Make sure that "TNSNAMES" is listed as one of the values of the
//        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA)
//      - Verify that a TNSNAMES.ORA file exists and is in the proper
//        directory and is accessible.
//      - Check that the net service name used as the connect identifier
//        exists in the TNSNAMES.ORA file.
//      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
//        file. Look for unmatched parentheses or stray characters. Errors
//        in a TNSNAMES.ORA file may make it unusable.
//   - If you are using directory naming:
//      - Verify that "LDAP" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Verify that the LDAP directory server is up and that it is
//        accessible.
//      - Verify that the net service name or database name used as the
//        connect identifier is configured in the directory.
//      - Verify that the default context being used is correct by
//        specifying a fully qualified net service name or a full LDAP DN
//        as the connect identifier
//   - If you are using easy connect naming:
//      - Verify that "EZCONNECT" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Make sure the host, port and service name specified
//        are correct.
//      - Try enclosing the connect identifier in quote marks.
//   See the Oracle Net Services Administrators Guide or the Oracle
//   operating system specific guide for more information on naming.
