TNS-03505 error

Hi,
I've got a TNS-03505 error on a PC trying to connect to 2 differents databases. The tnsnames.ora seems correct :
HPERISQOP.ARPEGE.SOCGEN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.128.162.193)(PORT = 1548))
(CONNECT_DATA = (SID = hperisqop)(SERVER = DEDICATED))
HPERISQOP2.ARPEGE.SOCGEN =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.128.162.187)(PORT = 1572))
(CONNECT_DATA = (SID = hperisqop2)(SERVER = DEDICATED))
I can connect to the first database but not the second. Have you got an idea or a solution ?
Regards,
Olivier D.

Looks like there is some problem with the second entry or some other entry in your tnsnames.ora file.
cut and paste the tnsnames entry(which is not working) on the top of tnsnames.ora and makes sure no other entry with the same name in tnsnames.ora file and test is tnsping is working or not?

Persistent TNS-03505 error

Hi
I am getting the tns-03505 error when trying to connect. I have used a known good tnsnames.ora file, and can connect with the IP but not service name.
The same happens with TNSPing - as in I can ping IP but not service name.
Any help greatly appreciated.
Best Regards
Jamie

Can you post the relevent tnsnames.ora entry?
What happens when you ping the host name (not service name) specified in the tnsnames.ora file?

Check that uiivs1.world is present in the Client TNSNAMES.ORA file, in D:\oracle\ora92\network\admin.

About error TNS-03505

Hi to all,
I have created a DB Link to remote MS SQL Server DB and I have modified the listener .ora and tnsnames.ora files.
The link work fine fine; if I try to query a remote table, the data are correctly displayed.
But if I run the tnsping <myconnection> an error TNS-03505 is returned.
Can You help me ?

thanks in advance.looks like listener is not running on the database server you are trying to connect to *(ORA-12541TNS- no listener)*. even though you have configured both tnsnames and lisnterner.ora files, you have to start listener for clients to make connections to db. hope this helps. set your oracle home and then type as below. these commands are very simple and I don't think I need to explain them.
cmd> lsnrctl status
cmd> lsnrctl start
cmd> lsnrctl stop

Ora-12154 vs. tns-03505

Since both ora-12154 and tns(ora)-03505 deal with not being able to locate a connect string in tnsnames (or other naming method), has anyone ever seen a good definition of exactly what differentiates between the two? What little variable would trigger the issuing of one error msg.vs. the other?
I know how to resolve them. The web is full of descriptions on resolving the problem (some of them are even valid! ;-) ). But I've never seen anything that would define why you would see an ora-12154 on time, and an tns-03505 another time.
Inquiring minds want to know! (Since this deals with published error codes, it's <i>somewhat</i> less arcane than how the archiver determines the "first" member of a redolog group! :-)

Senior Oracle DBACould be. I never picked up on any pattern of behavior before (thus my question). A simple test seems to bear that out:

TNS-03505: Failed to resolve name while do TNSPING "SERVICE-NAME"

Dear All,
I am unable to connect to DB on Windows thru SQLPLUS DB/PWD
Also, when doing tnsping, it thru below error message- please help
Used parameter files:
D:\app\Administrator\product\11.2.0\client_1\network\admin\sqlnet.ora
TNS-03505: Failed to resolve name
Regards,
Anand

ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 NEVER involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ORA-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

Tnx for replying, but is did this is mine INITATS_CFG.ora
it is placed in the hs\admin directory of the database
sql2000 is also the name of the ODBC.
# This is a sample agent init file that contains the HS parameters that are

TNS-12518 error while trying to fetch data from SQL Server

Hi everyone,
I'm trying to establish connectivity from Oracle 10.2 server to a SQL Server 2005. These are the server details
DOVER - This is where I installed Oracle Gateway for SQL Server. There's already an Oracle home in this server and I have used the existing listener for the incoming connections
LUNDY - This is where my actual Oracle server resides
HEBRIDES - This is where SQL Server 2005 instance resides, the database name is TRACKIT90
I've set everything as explained in Oracle documentation http://download.oracle.com/docs/cd/B19306_01/gateways.102/b14270/ch2.htm#i1005694 but in the end I'm getting an TNS-12518: TNS:listener could not hand off client connection when I run a test query and this is what it says in the listener.log of DOVER
01-MAR-2010 15:33:19 * (CONNECT_DATA=(SERVICE_NAME=tg4msql)(HS=OK)(CID=(PROGRAM=w:\oracle\product\10.2.0\db_1\bin\ORACLE.EXE)(HOST=LUNDY)(USER=))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.0.0.58)(PORT=3887)) * establish * tg4msql * 12518
TNS-12518: TNS:listener could not hand off client connection
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory
My initialization parameter under \\ORACLE_HOME\tg4msql\admin of gateway installation in DOVER is as below:
HS_FDS_CONNECT_INFO=hebrides.TRACKIT90
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
The listener.ora of the active listener in DOVER has the following lines, by the way this listener does not reside on the same ORACLE_HOME as the gateway's ORACLE_HOME but it is the current active listener in the server. The listener has also been stopped and started:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dover)(PORT = 1521))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
SID_LIST_LISTENER =
(SID_DESC =
(SID_NAME = tg4msql)
(ORACLE_HOME = E:\oracle\product\10.2.0\tg_1)
(PROGRAM = tg4msql)
The following entry has been added to the tnsnames.ora in LUNDY server where my actual Oracle database resides.
TRACKIT_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = DOVER)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = tg4msql)
(HS = OK)
And finally a database link is created by using the below DDL statement:
CREATE DATABASE LINK "DLINK" CONNECT TO "username" IDENTIFIED BY "password" USING 'TRACKIT_DATA';
When I do a select statement on one of the tables of TRACKIT database by using the following query I got the TNS-12518 error with above details
select * from announcement@dlink;
I would appreciate any help and also please let me know if I missed out any details.
Thanks.

This is the output comes with the "lsnrctl service listener" command on DOVER server

Although this question is completely off topic of the Personalization you can learn how to configure the SQL*Net connect from the manual by reading the topic "Configure the Client to Use a Net Service Name" found at the following link:

You're attempting to go across SQL*Net. I'm a unix guy so I can't help very much except to point this out.
On Unix I'd either undefine the TWO_TASK environmental variable. Probably a reg entry on 2k.
Or configure Sql*Net.
