Mapping Deployment Has Error:  Duplicate Database Link Exists

Hi everyone,
This is hopefully a simple question. I've been working with OWB 10GR2 for awhile now with no problems. My project finished and I moved on to another OWB environment, still 10GR2 and now my mapping deployments are having errors during the deployment. Each time I try to deploy the mapping, OWB also tries to create the database link, regardless of the fact that it already exists. It fails to deploy the database link but the mapping successfully deploys nonetheless. If I drop the database link and then deploy a mapping there is no error but then if I deploy a second mapping it comes back again (no real surprise here).
I tried to deploy the connector by setting it to "replace" and hit deploy. That was fine, but according to, OWB,even though I just replaced the exisiting DB link, it still didn't see that it was created. OWB still considered this connector as "New".
Does anyone know what I need to do to get OWB to stop trying to deploy the DB link with every mapping? How can I tell it that the DB link exists and is correct?
Thanks!
-Joe

Hi there,
I experienced same issue a few days ago ... I'll tell you how I solved it.
I think the real problem is that the link gets never marked as deployed => so, it's deployed with every single mapping which is using it!
You can even try to deploy it on its own, and deploying process ends with no errors, but it is not marked as deployed ...
Why can't the link be marked as deployed? Where does the db_link come from?
The link is pointing to a location where you dragged from a table (or any object) to your mapping.
In my case, the location was first created and registered by another user before starting project development (with a new user).
I unregistered the location with the original user and registered it again with my user, than I could deploy it and got it marked accordingly.
It's never again apperead within my mapping deployments.
Hope I've been clear enough ... and helpfull!
Joan.

  • On deploy tries to recreate database link?

    I have a problem when deploying a mapping.
    I keep getting the error ORA-02011: duplicate database link name.
    After I analyzed the Job Details of this deploy and the one of the mapping that is very similar to this one in the same location, I noticed that the one that gives problems tries to do Create of a location. The other one does a Replace of a location (database link). Both mappings are at the same location and the source and target locations are the same for both mappings.
    Sounds familiar? What coud be the problem?

    Hi!
    Probably you can check the connector status. In Control Center, you can expand the connector status and see what you have.

  • Admin tool error: Physical database already exists

    Hello Gurus,
    I am using OBIEE 11.1.1.3 and trying to import a new Essbase ASO cube into my RPD using the Admin Tool. I am getting the error message "Physical database already exists, but it is not of the same provider type". The cube is new and not in my rpd yet so why is it saying it exists? Is there a way to search for it in case it is in there?
    Thanks very much for your help.
    Regards,
    JennC
    Edited by: user754680 on May 13, 2011 5:06 PM

    You can search for the Tables, Cubes, Databases etc that are already in the repository. Just click on tools in the admin tool and select query repository. Here you can select from the drop down list what you are looking for and leave the name as * if you want to search for everything.
    Hope this helps.
    Thanks,

  • Error in database link(ORA-02063 and ORA-02391)

    Hi
    database link was working fine till this morning. now when i try to query using the database link, i get the following error
    ORA-02391: exceeded simultaneous SESSIONS_PER_USER limit
    ORA-02063: preceding line from RMSLIVE
    It would beof great help if you can advise why this error is occuring.
    many thanks.

    The error stack is quite obvious.
    Either, the profile, with which the database user on remote database is running, must be modified to allow more connections or investigate the session leak in the application talking over database links.

  • 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.

    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.

    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.

  • Deploying a mapping creates a database link

    I have one mapping where everytime I deployed a mapping it always creates a database link. How do I remove this and how did this happen?

    Is the problem that you expect a local reference like SCOTT.EMP rather than SCOTT.EMP@DBLINK? Check the source and target locations for the tables in your mapping, check that the locations are defined identical in the host:port:service name? Did you define them with H:P:S? May be one has localhost the other a machine name or something.
    Cheers

  • ORA-02020 too many database links

    Hello,
    I'm getting the ORA-02020 too many database links error in my Apex application. This error occurs when I run an interactive report in a page. There are 21 pages and 7 database links in the application. Each page has one interactive report that references one database link in the region source.
    The database links are referenced in each page as follows: database link1 (page 1); database link2 (pages 2 and 3); database link3 (pages 4-7), database link4 (pages 8-15); database link5 (pages 16-18); database link6 (pages 19); and database link7 (pages 20-21). Each database link is referenced to separate schemas in one remote Oracle database.
    I tried to eliminate the error by setting the open_links and open_links_per_instance parameters in the init.ora file of the remote and XE databases to 100 then restarted the both databases. This solution did not work. I created separate Application Processes from the Shared Components to close each database link by implementing the following:
    Click on Shared Components&gt; Logic &gt; Application Processes &gt; Create &gt;
    Name: CLOSE_LINK1
    Sequence: 1
    Point: On Load: Before Header (page template header)
    Type: PL/SQL Anonymous Block
    Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
    Error Message: Database Link Error
    When I run the application now, the ORA-02081: database link is not open error appears.
    Please help anyone! I know someone has experienced these same errors.
    Thanks,
    Ms. H

    Joel,
    Thank you for your quick response. For clarification purposes, could you provide samples for 1) issuing the CLOSE DATABASE LINK and catching the exception; and 2) querying from V$DBLINK prior to issuing the CLOSE DATABASE LINK from the Shared Components &gt; Logic &gt; Application Processes?
    Lets assume the following query with a database link in the region source is referenced for Page 1.
    Page 1 - Employee Listing
    Region Source:
    select ename, job, hiredate
    from scott.emp@link1
    Lets assume the following Application Processes from the Shared Components is referenced to close the database link:
    Click on Shared Components&gt; Logic &gt; Application Processes &gt; Create &gt;
    Name: CLOSE_LINK1
    Sequence: 1
    Point: On Load: Before Header (page template header)
    Type: PL/SQL Anonymous Block
    Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
    Error Message: Database Link Error
    My thoughts are to do the following:
    1. Log in SQL*Plus as SYS
    SQL&gt; grant select to v_$dblink to scott;
    2. In Apex, goto Shared Components&gt; Logic &gt; Application Processes and add the following queries in the Process Text:
    Name: CLOSE_LINK1
    Sequence: 1
    Process Text:
    select db_link from v$dblink;
    execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
    3. Catch the exception???
    Your assistance is greatly appreciated. :8}

    Do I need to modify the NLS settings in the SOURCE database before executing a script to insert data into the TARGET database?
    Thanks, Jack

    The difference in settings is not a problem by itself, especially that only the NLS_CHARACTERSET matters. Of course, this difference may lead to certain issues if not taken into consideration.
    Please, describe symptoms of your problems.

  • Database link from Oracle8i to Oracle9i

    Hi,
    I am trying to create a database link from an oracle 8i database to connect to an oracle 9i database ... When testing the connection , I always receive an error "The Database link is not active"
    Notes
    1- Creating a database link that connects from the same 8i database to another 8i database succeeds. This gave me the impression that it is a compatibility problem but I am not sure.
    2- I changed the initialization parameter
    global_names = falseand restarted the Oracle database
    3- the 2 databases are on the same domain
    Did anyone pass through this problem before ??
    thanks

    Well, I was testing the database link via DBA studio and there was no ora error associated with the message.
    A friend helped me to identify and sove the problem. here is what he did.
    Lets assume that the oracle8i database called Ora8i
    and the oracle9i database called Ora9i
    and that the network domain name is OraTest.com
    When i select * from global_name; on both databases
    Ora8i database return ==> ora8i
    Ora9i database return ==> Ora9i.us.oracle.com
    We then execute the following statement on Ora9i database
    alter database rename global_name to Ora9i.OraTest.com;
    Testing the database link after that went fine.
    Thanks

  • ODP AND DATABASE LINKS ???

    Hi, some very weird stuff going on here:

    Also, I will materialize the view and try it, but it has got to be the ODP, the sql executes fine via slqplus, toad, etc, and It's not the grid, I bound the first column to a dropdown and got the same result.
    My ENV:
    Local DB 8.1.7.3 - I think
    Remote DB 9 release 2
    OPD: 9.2.0.4.01

    Further testing has revealed:
    The database link works fine when connected to another 8.1.7.4 instance as opposed to the 9.2.0.3.0 instance.
    It makes no difference if the link is public or private.
    Creating a materialized view with the database link in it to the 9.2.0.3.0 instance also works fine.
    However none of the above is a solution.
