Help tns service erroe

I installed forms 6i and oracle 10g. I can sign in the db called Test using sys but when i tried to connect usng the form builder i get this error
ora-12154 TNS service could not resolve service name
on the log on screen i use sys and the syspassword and database as Test and i get the above error
this is a copy of my tnsnames.ora file.
can anyone help me please

Hi,
Try to copy the Tnsnames.ora file of the Data base to the Network/Admin location where Forms got installed.
And ensure that the service is started.
Hope this works

TNS Service Name is : OracleORACLE_HOMETNSListener and is failing to start

I think one of my guys has been messing with the configuration of my Oracle 10g server and not being an expert in this I am somewhat bermused !!
Can anyone tell me where the TNS Service is picking up its name from....as you can see it contains ORACLE_HOME instead of the name of the oracle instance.
Please help me if you can
Many Thanks in advance,
Andy

Can I make Oracle/Microsoft Odbc connection without TNS service???

Hi All,
I want to make ADODB connection to oracle 10g database. For this currently I am using odbc connection, which requires TNS service setup in my pc. Hence I need to install Oracle client on my pc as well. Which requires license.
So is there any alternative, with which I can make my ADODB connection without TNS service implementation. Or any inputs on this will do for me. Only the thing is i need some freeware with which i can do this.
Thnx,
kc

Hi,
Well I think you might have landed in the wrong forum.
This forum is for the Oracle Call Interface (OCI) which is a C programming interface to Oracle.
Your question doesn't look to be about that unless I am misreading it.
Perhaps you are looking for the Oracle Data Access Components (ODAC) downloads?
These include client software in addition to the various data access components on Windows.
ODAC is located here:
http://www.oracle.com/technetwork/developer-tools/visual-studio/downloads/index.html

TNS Service starting error- Windows 7.0 Home premium- 64bit machine

I bought a new DELL Inspiron machine, where windows 7.0 home premium was installed. It is now a 64 bit system.
I installed Oracle 10g database. It goes well until end, but throws TNS Service could not be started as an error message at the end. However, it mentions that the error could be resolved by starting the service manually. I tried to do that, but I get TNS: Permission Denied error.
I started installation process by login to adminstrator login. I tried starting the TNS service with admin login.
Is the error message I am getting because of 64 bit machine? Is permission denied because of Home premium?
Let me know and suggest your advices.
Please suggest if there are any turn around for this issue. I am trying to solve this from past 15 days.

My views is you didn't read my response.
So here it is again
Oracle doesn't run on Windows Home. Period. Windows Home doesn't have accounts.
Oracle 10g doesn't run on Windows 7. Moreover it is desupported.
11gR2 is about to be certified on Windows 7, but not on Windows Home.

URGENT: Problem with tns services

Hi everybody,
I have two 10.2.0 databases: one on Windows XP prof and the other on a firewall-enabled Linux RHE AS , the latter is using ASM. I easily define tns services for the windows one from Linux but cann't do the same vice versa. I have added 1521:tcp to firewall safe sockets. The service is up and running on Linux and the listener is OK. What is the problem then?

TNS service error while DBLOGIN in ggsci...

Hi...
I am connecting my oracle 11g v 11.2.0.2 to Oracle golden gate. While running the DBLOGIN cmd it gives me the TNS service error... Please let me know the solution as, I am new to oracle golden gate.
ERROR:-
GGSCI (localhost.localdomain) 2> DBLOGIN USERID ggs_owner,PASSWORD ggs_owner
ERROR: Unable to connect to the database using user ggs_owner. Please check privileges.
ORA-12162: TNS:net service name is incorrectly specified.
Please reply me...
Thanks...

To use a TNS alias, make sure that we are able to do a tnsping as well as connect via SQL*PLUS using that alias before we launch GGSCI.
In the relevant parameter file (in this example an extract parameter file) we just add the TNS alias to the USERID as shown below:
USERID ggs_owner@<TNS-alias name>, PASSWORD ggs_owner
e.g.
DBLOGIN USERID ggs_owner@toprod, PASSWORD ggs_owner
Hope it is done for you....

TNS Service Names

I am unable to get the ODBC Driver version 8.1.6.4.0 to get a list of TNS Service names from a shared TNSNAMES.ORA file. If I type in the service name and test the connection the test is successfull so I know that the shared file is being used. Is there a way to get the TNS services from a shared tnsnames.ora file to be listed in the pulldown?

Can future versions of the ODBC driver get the location of the TNS names file from the registry if the TNS_ADMIN value exists for the ORACLE HOME corresponding to the ODBC driver you are using?

Resolving a Server Name from a TNS Service Name

A computer client has an Oracle ODBC connection that is attached to a TNS Service Name "X". The TNS Service Name is running in Server "Y".
Does anybody know a quick way to resolve the Server Name "Y" from the TNS Service Name "X" ???
Our current solution is based on opening the file tnsnames.ora, which is normally located in $ORAHOME\network\ADMIN\TNSNAMES.ORA, and by parsing the file resolve the server name. However, we were wondering if there would be a more reliable way to do this. Is there an Oracle API that we can execute? Something like "GetHostName(TNSServiceName)"?
Many Thanks

Not that I'm aware of.
If you were using an Oracle Names server to resolve tnsnames, rather than a tnsnames.ora file, this would be a lot easier. You'd just update the Oracle Names server and all the clients would start pointing at the right machine.

48 character limit on TNS Service Name

In the Oracle ODBC Driver Configuration Dialogue Box there is a 48 character limit in the TNS Service name file. In my case, I need 56 characters if I use the //HOST:PORT/service_name format. The service_name is the format SID.host. The full TNS service name can get quite long since the host is repeated twice.
For me a workable workarounds is to use the IP address in the HOST field (but not the service_name). I didn't test, but another workaround I presume is to use a TNS_NAMES.ora file, but that adds complexity to a tool that's supposed to be simple.
Better yet, Oracle developers need to make the TNS service name field a bit longer (96 chars?).
Now that it is working I am happy with the concept and usability of the Instant Client.
Trenton

Hi!
I found the error:
TNS_ADMIN=C:\Oracle\instantclient_10_2\network\admin\tnsnames.oraThat's wrong. The environment variable TNS_ADMIN has to point to the directory containing the tnsnames.ora file; it must not contain the complete path to the tnsnames.ora file.
After changing TNS_ADMIN to C:\Oracle\instantclient_10_2\network\admin, all is fine.
Thanks,
Alexander

Oracle8i Start problem - TNS:Service Name Incorrect

Hi Folks
My installation of Oracle8i was working fine. I installed webDB today and that was worked fine too.
But before shutting down the machine I forgot to shutdown the database.
When I reboot and try to start the database as root thus: ./oracle8i start, I get the following error -
ORA-12162 TNS:Service name is incorrectly specified.
Looks like something is wrong with SID or TNSNAMES.
Could somebody suggest a solution please.
Thanks.

For information sake, if someone else comes across the same situation, here is the cause and solution:
When webDB2.2 is installed it seems to make an entry in the /etc/oratab file for the service name that is provided during installation. Cosequently my 'oratab' file went from:
ora8i:/../oracle/product/8.1.6:Y
To:
*:/../oracle/product/8.1.6:Y
ora8i:/../oracle/product/webdb22:N
Hence the problem when 'oratab' is invoked.
I don't know if webDB is supposed to make this kind of a change.
I replaced the '*' with 'ora8i' and everything works fine including webDB

TNS Service Name

While I am configuring DNS for Oracle 10g at that time i come to the TNS Service Name
but as i dnt know what TNS Service means ?? I wanted to know what does it stand for ?
And also I am seeing three options to select named as below
EXTPROC_CONNECTION_DATA
ORACLR_CONNECTION_DATA
XE
I also wanted to know the purpose of each above attributes. So please Guide me..!! and know me what it means ?? Thanks in advance

You can refer this http://www.ispirer.com/wiki/sqlways/users-guide/setting-up-database-connection/oracle/tns-service-name
TNS service name is used to connect to a database remotely.
PROD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <HOSTNAME>)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = prim)
In the above example, PROD is the NET ORACLE SERVICE NAME(alias name). This is used while connecting to the database from the remote server.
Host is the hostname where the database resides.
SERVICE_NAME is the db_unique_name of the database that you are connecting.
So when connecting to the database remotely, you use
sqlplus username/<password>@<connection string>
sqlplus username/<password>@<prod>

TNS service name gives preference to connect instance which is in a mount

OS:HPUX
Oracle version: 11.1.0.7
why TNS service name give preference to connect instance which is in a mount mode and dsiaply 'ORA-01033' as mentioned below.
I wanted to connect only instance which are OPEN(not MOUNT) using connect string and want to know status of all instances using SQL query "select instance_name,status from gv$instance". How can I achive this?
I have four node rac cluster and four instance, one instance on each node and status of instances are as shown below
SQL> select instance_name,status from gv$instance;
INSTANCE_NAME STATUS
dtrac1 OPEN
dtrac4 STARTED
dtrac3 OPEN
dtrac2 MOUNTED
I have tried to connect using "dtrac" service name ( details of tnsnames gives below) from any node it gives priority to instance which is mount and shows following error messages
SQL> conn system/vcs@dtrac
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress Process ID: 0 Session ID: 834 Serial number: 139
Warning: You are no longer connected to ORACLE.
SQL> conn system/vcs@dtrac
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress Process ID: 0 Session ID: 834 Serial number: 139
SQL> conn system/vcs@dtrac
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress Process ID: 0 Session ID: 834 Serial number: 139
SQL>
when I changes dtrac2 instance to either NOMOUNT or OPEN state then connection properly goes to instances which are OPEN state.

Hi Bjoern
Thanks again for your input.
I have some commnet on your input.
I have started instance in mount mode using sqlplus. But it doesn't make diffrence if I stated using srvctl since service get ready as we started instance either OPEN/MOUNT mode using srvctl or sqlplus.
As you are saying diffrent way of configuration of service by mentioning preferred and available attributes for instances but its not useful to know instances which are open. Its useful for segregate work to specific nodes by creating diffrent services for diffrent application.
'crs_stat -t' shows resources online even instance is either nomount/mount/open state. I want to exact state of instance so its not useful for me.
Below example showing service get READY status even I start instanc with mount option using SRVCTL

ODBC TNS Service drop down filled with garbage records.

We have Oracle installed on our network. I am trying to install the Oracle ODBC drivers onto my Windows XP machine to create a connection to use in Crystal Reports XI.
I do not have any oracle products installed on my machine so I downloaded the basic client and the client odbc zip files and installed them into a local directory and then ran the install odbc exe and added the windows PATH which installed the odbc source. When I add a new Windows ODBC Data Source on the configuration screen the list of TNS Service names is filled with dozens of garbage records. I would guess this is not correct so how do I resolve this? I assume this is suppose to be a list of connections to oracle databases read from a tnsnames.ora file but I could be wrong. I find no tnsnames.ora file on my computer but I assume there is this file in the oracle directories on the server somewhere. I am not sure where to go from here. Can anyone advise on how to get the connections I need and clean up the garbage? Thanks.
Rick

Hi,
I am having the same issue, did you ever resolve this issue ?
I do have a reg setting and enviroment variable for this setting that both point to the same place and I can actually use odbc to create connections but when I use the drop down list I just get garbage.
Simular setup to your , xp sp3 , instant client , odbc client , sql client.
I also have an nls_lang as well as adding the path of the isntall to the path var.
