Error Creating Database link

Hello Everybody,
I am getting the following error while creating the database link using the connection information at OWB Client.
Testing...
Failed.
ORA-12514 TNS: no listener
*Cause: The connection request could not be completed because the listener is not running
*Action: Ensure that the supplied destination address matches one of the addressed used by the listener
-compare the TNSNAMES.ORA entry with the appropriate LISTENER.ORA file
Start the listener on the remote machine.
The version of OWB Client is 10.1.0.2.0.
When queried at oracle using the userid which i used to login OWB Client i.e. as shown below
select db_link from all_db_links - the database link is created. But none of the obects are accessable with the db link.
Note: I am able to create a database link explicity by issuing the command at backend oracle i.e create database link etc. and also able to access the tables.
Kindly help.
Thanks
Prashanth

my guess is that you can create the database link, which simply points to the remote instance. however, the problem is on the remote instance.
As the error message suggest, make sure that the listener is up and running on the remote machine. The link can be created, but if there is no listener on the other side, you will not get any response.

How to create Database link

Hi all,
While trying to create a database link i am getting the following error:
Create Database Link Failed.
ORA-01031: insufficient privileges
Could you please tell me how to create a database link.
Thanks
Grishma

Hi Grishma,
Login as DBA (SYSTEM or SYS for ex.) in SQL*Plus and run this command:
SELECT *
FROM dba_sys_privs
WHERE grantee = 'USERNAME'
AND PRIVILEGE = 'CREATE DATABASE LINK'
Change the USERNAME by the USER you're trying to create the database link from. (CAPITALS!)

- Verify that a TNSNAMES.ORA file exists on your repository server
in the proper place and is accessible. See the operating
system specific manual for details on the required name and location.
- Check to see that the service name exists in one of the
TNSNAMES.ORA files and add it if necessary.
- Make sure there are no syntax errors in the file.
Particularly look for unmatched parentheses or stray characters.
Any error in a TNSNAMES.ORA file makes it unusable. See
Chapter 4 in the SQL*Net V2 Administrator's Guide. If possible,
regenerate the configuration files using the Oracle Network Manager.
Is there anything wrong in my configuration. Please help me in getting out of this problem.
Thanks in advance

Error using database link

Before creating the link, I went into my init.ora file and made sure the GLOBAL_NAMES entry was false.
I then created a database link using the following:
create public database link cindy_link
connect to system identified by syspswd
using 'PRECISEI';
My link was created, but when I attempt to use it, I get the error:
ORA-02085:database link CINDY_LINK.WORLD connects to PRECISEI.WORLD
Here is the entry from my tnsnames.ora file:
PRECISEI =
(DESCRIPTION =
(ADDRESS_LINK =
(ADDRESS =(PROTOCOL = TCP)(HOST = taurus)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = precisei.world)
Here is the entry from my listener.ora file:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = precisei.world)
(ORACLE_HOME = E:|oracle\ora81)
(SID_NAME = precisei)
(I must admit to not having a full understanding of SID_NAME vs SERVICE_NAME.) I looked in dba_db_links, and my db_link is named CINDY_LINK.WORLD instead of CINDY_LINK.
Do I have a problem in one of my files?
I would really appreciate any help.
Thanks.

Well, I was facing the same problem but corrected it later on. Let me describe the solution is little detail.
You need to check few things before creating db link.
1) db_name and db_domain in init.ora file
2) global_name in listener.ora file
3) service name in tnsnames.ora file.
It seems to me that you have not specified the db_domain in init.ora file. And in that case, you need to follow these steps.
I am considering here that you have database A on server X and database B on server Y.
Go to the first server (server X).
set the global name in init.ora file by following
Global_name=true
db_domain=usa.com
Start and open the database.
connect as system user.
(if your oracle sid is orcl then)
svrmgr30>alter database rename global_name
to orcl.usa.com;
this will set the global_name as specified in init.ora file. Here, your SID is orcl and db_domain is usa.com so global_name will be orcl.usa.com.
svrmgr30>Select * from global_name;
You get the answer like this.
Orcl.usa.com
Now, go to Listener.ora file and change global_name to the new name (orcl.usa.com)
restart the listener.
WE WILL SEE ABOUT THE CHANGES OF TNSNAMES.ORA LITTLE LATER.
Now, go to second server(server Y) and perform the same operation as defined above. i.e. Specify the db_name, db_domain in init.ora file, execute "alter database.." command for setting global_name and edit listener.ora file for new global name.
Once you do all these you need to create service on server 1 to connect to server 2 and on server2 to connect to server1.
Go to server X.
Open tnsnames.ora file and create an entry like this.
P =
(DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = IP address of B)(Port= 1521)))
(CONNECT_DATA = (SID = P))
Here, P is global name of P ( at both the places).
Now, go to server Y.
Open tnsnames.ora file and create an entry like this.
Q =
(DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = IP address of A)(Port= 1521)))
(CONNECT_DATA = (SID = Q))
Here, Q is global name of Q ( at both the places).
you are all set now.
Create database link between 2 servers now.
Say these are all your settings..
Server X is having database A with global_name orcl.usa.com and server Y is having database B with global_name orcl2.us.com
Now go to server X and create db link to server Y
Create public database link orcl2.us.com using 'orcl2.us.com'
(Note. don't miss to create a service 'orcl2.us.com' in server X's tnsnames.ora file)
And go to server Y and create db link there.
Create public database link orcl.usa.com using 'orcl.usa.com'
(Note. don't miss to create a service 'orcl.usa.com' in server Y's tnsnames.ora file)
hope this helps,
If this doesn't work, feel free to contact me.

How to create database link between oracle and SQL Server

Hello Everyone,
Here i have Oracle Database 9i and SQL Server 2005 databases.
I have some tables in sql server db and i want to access from Oracle.
How to create a database link between these two servers
Thanks,

Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a)     Oracle 10g software
b)     User account to access SQL Server database (sa/abc@123!)
c)     Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1)     Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2)     Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3)     Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST    <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4)     Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =
(SID_LIST =
(SID_DESC =
(SID_NAME = SQLTEST) *+< Here SQLTEST is DSN NAME >+*
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc))
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5)     Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6)     Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora
something=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST =192.168.0.175) (PORT=1525))
(CONNECT_DATA=
(SID=SQLTEST))
(HS=OK)
$ tnsping something

Steps to create database link

i got these info from my teacher to create database link
1.     Establish the network connection.
2.     Shutdown the database. (SQL>shutdown immediate ;)
3.     Open and modify the pfile and set GLOBAL_NAME = FALSE.
4.     Create spfile from pfile. (SQL>create spfile from pfile;)
5.     Startup database. (SQL> startup;)
6.     Modify tnsnames.ora file, set the destination computer service name and other in formations.
ASIF.com =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ONE)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL)
7.     Crate database link .
SQL>create public/private database link abc
     Connect to scott
     Identified by tiger
     Using asif.com;
in step 3, which pfile should i modify
i got a file in F:\oracle\admin\fahmi\pfile named init.ora.31620060327
but there is no line like GLOBAL_NAME = FALSE
so watching the sample i add this line in init.ora.31620060327
global_names = FALSE
am i right...........??
can anyone help me...??
i have some few other questions.....................

The following is an excerpt from http://www.oracleutilities.com/OSUtil/ping.html
The tnsping utility is used to determine whether or not an Oracle service can be successfully reached. If a connection can be established from a client to a server (or server to server), tnsping will report the number of milliseconds it took to reach the remote service. If unsuccessful, a network error will be displayed. However, tnsping will only report if the listener process is up and provides no indication of the state of the database.
$ tnsping <net service name> <count>
The net service name must exist in the tnsnames.ora file. This file is used by clients and database servers to identify server destinations. It stores the service names and database addresses. The count parameter is optional and will show the number of times the command should try to connect to the specified service name.
After this I suggest you to check your $ORACLE_HOME/network/admin/sqlnet.ora.
Look for what is configure for:
NAMES.DEFAULT_DOMAIN
NAME.DEFAULT_ZONE
This must be compatible to what you are using in your tnsnames.ora.
By the way, don't forget to check if there is a log file (sqlnet.log) in your $ORACLE_HOME/network/admin directory.
Regards.

Unable to access table even after creating Database link

Hi
I have created a data base link.It was created properly.
The Syantax that I have used is follows:
create database link X_link connect to User1 identified by User1 using 'Other_Database'
And on running the query:
select count(*) from table1@X_link
I am getting the error as follows:
TNS could not resolve the connect identifier specified... TNS: could not resolve the connect identifier specified.
Please tell me where is the problem?
Thanks in Advance

Your database link does not work because the entry you used does not exist in the tnsnames.ora in the database $ORACLE_HOME.
Login to the database server, set the environment, and try to tnsping the entry you used for the database link, then fix the tnsnames.ora file (probably in $ORACLE_HOME/network/admin)
You can test a database link using :-
select sysdate from dual@link;

OWB 10g -- Can't Create Database Links for Data Source and Target

We installed OWB 10g server components on a Unix box running Oracle 10g (R2) database. The Designer Repository is in one instance. The Runtime Repository and the Target are in another instance. The OWB client component was installed on Windows XP. We create a data source module and a target module in OWB. The data source is on another Unix box running Oracle 9i (R2) database. We try to create database links for data source module and target module, respective. But when we created and tested the DB links, the DB links were failed.
For the database link of data source, we got the following error message:
Testing...
Failed.
SQL Exception
Repository Error:SQL Exception..
Class Name: CacheMediator.
Method Name: getDDEntryFromDB.
Repository Error Message: ORA-12170: TNS:Connect timeout occurred
For the database link of target , we got the following error message:
Testing...
Failed.
API2215: Cannot create database link. Please contact Oracle Support with the stack trace and the details on how to reproduce it.
Repository Error:SQL Exception..
Class Name: oracle.wh.ui.integrator.common.RepositoryUtils.
Method Name: createDBLink(String, String, String, String).
Method Name: -1.
Repository Error Message: java.sql.SQLException: ORA-00933: SQL command not properly ended.
However, we could connect to the two databases (data source and target) using the OWBs utility SQL Plus.
Please help us to solve this problem. Thank you.

As I said prior the database link creation should work from within the OWB client (also in 10).
Regarding your issue when deploying, have you registered your target locations in the deployment manager and did you first deployed your target location's connector which points out to your source?
I myself had some problems with database link creations in the past and I can't remember exactly what they were but it had something to do with
- the use of abnormal characters in the database link name
- long domain name used in as names.default_domain in my sqlnet.ora file
What you can do is check the actual script created when deploying the database link so see if there's something strange and check if executing the created script manually works or not.

Can't create database link when password has special character

I'm trying to execute the following statement within sqlplus
create database link alpha connect to scott identified by tiger! using 'db_alpha'
note that the password for the account has an exclamation point in it. the command fails. I've tried placing the password in quotes (') and double-quotes ("). The double-quotes work, but then the link fails to function properly.
We are required to have a special character in our passwords... so how do I get that special character into the password for the database link?
Thanks in advance,
Darren

for some weird reason, I can't post the reply I want. every time I try, the forum hangs and doesn't save the message. give me a sec...
I have put the password within double quotes... so I'm starting to think the problem is something else. I've been reading other posts regarding creating database links and I've obtained limited results. Here's what I've done, and the results I'm getting.
(names changed to protect the innocent)
My oracle database is on SYSA. I'm on SYSB. I set my TWO_TASK=SYSA and just use sqlplus to connect as user1.
I want to run a command on user2's tables. Normally I would just grant read access to user1 on user2's tables and use a command like
nert spaces to get this to save (weird forum bug here, I can't delete the text to the left)
SQL> sel{color:black}{color}ect * fr{color:black}{color}om u{color:black}{color}s{color:black}{color}e{color:black}{color}r{color:black}{color}2{color:black}{color}.{color:black}{color}m{color:black}{color}y{color:black}{color}_{color:black}{color}t{color:black}{color}a{color:black}{color}b{color:black}{color}l{color:black}{color}e{color:black}{color};
However, user2 is for test data and those tables get dropped and recreated often and it is cumbersome to try to remind everyone to recreate the grants. So I can't trust that user1 will have access to user2's tables. So my goal with the database link is to create a private (for user1 only) database link and access the tables that way, that way I bypass the grant issue. This works out better for me because we only change that password every 2 months. I just recreate the database link once every two months, rather than recreate grants multiple times every week. Well, that's the theory anyway.
Back to creating the database link, I thought my issue was the special character in the password because if I remove the exclamation point everyting works (except that the password is invalid). Below is what it looks like when I do this...
Attempt #1:
SQL> create database link BLAH connect to user2 identified by "tiger" using 'BLAH';
Database link created
SQL> sel{color:black}{color}ect * fr{color:black}{color}om my{color:black}{color}_{color:black}{color}table{color:black}{color}@{color:black}{color}BLAH;
sel{color:black}{color}ect * fr{color:black}{color}om my{color:black}{color}_{color:black}{color}ta{color:black}{color}ble{color:black}{color}@{color:black}{color}BLAH
ERROR at line 1:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from BLAH
So that looks like it's just a password issue. If I put in the correct password... the error changes to this...
Attempt #2:
SQL> create database link BLAH connect to user2 identified by "tiger!" using 'BLAH';
Database link created
SQL> sel{color:black}{color}ect {color:black}{color}* fr{color:black}{color}om my{color:black}{color}_{color:black}{color}table{color:black}{color}@BLAH;
sel{color:black}{color}ect * fr{color:black}{color}om my{color:black}{color}_ta{color:black}{color}ble{color:black}{color}@BLAH
ERROR at line 1:
ORA-02085: database link BLAH.AAA.BB.CCC.DDD connects to
DEVDB.AAA.BB.CCC.DDD
To me, that doesn't make sense. If the link isn't working... how did it get the "invalid username/password" in Attempt #1?
Anyway, in perusing other forum posts, one post said to put in the full text from the tnsnames.ora file instead of the alias. So I do a little cut/paste and try this...
Attempt #3:
SQL> create database link BLAH connect to user2 identified by "tiger!" using

Any ideas on what I'm doing wrong?

OWB can not create database link

Hello!
We use OWB 10.1. We are unable to create database link in the owb as a source for metadata information. The database user we use to connect to the owb have got the right to create database links and the same user can create database links outside the owb. we get the error message
Testing...
Failed.
API2215: Cannot create database link. Please contact Oracle Support with the stack trace and the details on how to reproduce it.
the database user is not the owner of the repository. if we use the repository owner to create the database link it works.
it is also impossible to use a database link, that is created outside the owb, if we use an user that is not the repository owner.
the error message is:
java.sql.SQLException: ORA-02019: connection description for remote database not found
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:158) ....
with the owner everything works fine.

hi,
If public dblink is a problem then u can create the table with PUBLIC SYNONYM and create a synonym of the table in ur DB so that u can access the table in ur DB and still make I/U/D in the table in the other DB. We just have to grant previlege for the synonym created for DML statements.

Special characters in password for "create database link"

It seems that one cannot create a DB link if the password has a special character in it (like '!')?
create database link MYLINK connect to SOURCE identified by mypwd! using 'MYDB'
- returns "ORA-00933: Command not properly ended"
create database link MYLINK connect to SOURCE identified by values 'mypwd!' using 'MYDB'
- returns "ORA-00988: missing or invalid password(s). This is the syntax that works in "create user".

Hi,
You need create database link to schema that is assigned to your workspace (application parsing schema)
Schema need have CREATE DATABASE LINK system privilege.
