• Create database link between two databases?

  Hi all
  
  Can someone tell me how to do?
  
  I have two databases in oracle 9i: 'mydb' & 'mydb1 '.
  
  mydb contains a table 'tab1' with a single domain (of the int data type) and mydb1 contains a table "tab2" with two fields (int, char).
  
  I tried to do this:
  
  System is one of the usernames and another username is olapsys
  Manager is the password of the system, and olapsys got the password = myolapsys
  
  I tried to create a link, but it gave me an error:
  
  CREATE DATABASE LINK mylink access the system identified by the Manager using "mydb.tab12";
  
  then I tried running this query in olapsys:
  
  Select * from tab12@mylink;
  
  Error:
  ORA-12154: TNS: could not resolve service name
  
  Help, please.
  
  Thank you and best regards,
  
  Lucky

  CREATE DATABASE LINK mylink to connect to the system identified by the Manager using "local service alias ';

  where local service alias is the name of the local service that you configured in the tnsnames.ora to connect to mydb1.

• Failed to create database link when the password has a special character

  I am trying to execute the following statement in sqlplus
  
  create alpha link database to connect to scott identified by tiger! using "db_alpha".
  
  Note that the password of the account has an exclamation mark inside. the command fails. I tried to put the password in quotation marks (') and double quotes (""). Working the double quotes, but then the link does not work properly.
  
  We are required to have a special character in our passwords... so, how can I get this special character in the password for the database link?
  
  Thanks in advance,

  Learn about the GLOBAL_NAMES initialization parameter. Default GLOBAL_NAMES = TRUE, which means the database link is required to have the same name as the database in which it connects. Database name DEVDB link or define GLOBAL_NAMES = FALSE:

  I don't have two databases, so in my sol10 database I create two database links sol10@Darren2 and sol11@Darren2 both pointing to itself (back to sol10 database). That's why I use qualifiers link db. The two links you connect as a Darren2 user with password Tiger!. The global database name is sol10 and initialization of setting global_names = true. As you can see what global_name (sol10) corresponds to the name of the link in sol10@Darren2 db (again, the link name is sol10 and Darren2 is qualifying link) select vai db link works OK. But the sol11@Darren2 link fails because the name sol11 link does not match the name db global sol10. However, as soon as I change global_names false, sol11@Darren2 works fine. It will be useful.

• A question about the CREATE DATABASE LINK PUBLIC and ORA-12154 error

  Hi all
  
  
  I have a problem on the public database link creation and I would be grateful if you could kindly give me a helping hand. I have the following connection settings in my
  tnsnames.ora file:
  

  ...
  DGPAPROD.WORLD = 
       (DESCRIPTION = 
         (ADDRESS_LIST = 
          (ADDRESS = (COMMUNITY=tcp.world)
            (PROTOCOL=TCP)(HOST=ORASR001)(PORT=1521)
           ) 
         )
         (CONNECT_DATA = (SID = DGPAPROD))
      )
  ...

  Having the above mentioned parameters, I can connect to this remote database directly in a SQL * more shell:

  $ sqlplus username/[email protected]

  It works pretty well and the connection is established without any problem.
  
  Now, what I want to do is to create a public database of this remote database link to avoid the user/connection of switch for the visualization of the
  the content of this database. I proceeded in line with the syntax indicated in the Oracle online documentation:
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_5005.htm#SQLRF01205
  
  This is why I run the following to create a public database link

  CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING 'DGPAPROD.WORLD';

  Apparently there is no error and the link is created successfully. However, it cannot resolve the remote host and every time I run this query
  (myenterprise is the name of a table in the remote database)

  SELECT *
  FROM myenterprise@SR001_dblink
  
  ERROR at line 1:
  ORA-12154: TNS:could not resolve the connect identifier specified

  What causes this problem?
  
  Thanks in advance,
  
  
  Kind regards
  Dariyoosh

  You must have defined DGPAPROD. WORLD in tnsnames.oar on the server where DB is runnig.

• Deployment of mapping a error: duplicate database link exists

  Hello world
  
  If all goes well, it is a simple question. I have worked with OWB 10 g 2 for some time now without any problems. My project finished and I went to a different environment of OWB, always 10 gr 2 and now my mapping deployments are errors during deployment. Whenever I try to deploy the mapping, OWB also tries to create the database link, regardless because it already exists. It does not deploy the database link, but mapping deploys successfully, however. If I drop the database connection, and then to deploy a map there is no error but then if I deploy a second mapping back again (no surprise here).
  
  I tried to deploy the connector by assigning 'replace' and click on deploy. Which was fine, but according to, OWB, even though I just replaced the existing link DB, it has not yet see it was created. OWB always considered this connector as 'new '.
  
  Anyone know what I need to do for OWB to stop trying to deploy the DB link with each mapping? How can I tell him that the DB connection exists and that it is correct?
  
  Thank you!
  
  -Joe

  Hello

  I had the same question a few days ago... I'll tell you how I solved it.
  I think the real problem is that the link never gets marked as deployed => therefore, it is deployed with each mapping is to use it!
  You can even try to deploy it on its own and deploy process completes without error, but it is not marked as deployed...
  Why the link can't be marked as deployed? Whence the db_link?
  The link points to a location where you dragged a table (or any object) on your map.
  In my case, the location was first created and saved by another user before starting the development of a project (with a new user).
  I recorded the location with the original user and he scored again with my user that I could deploy and get marked accordingly.
  It is never apperead in my mapping deployments.

  Hope, I've been pretty clear... and useful!

  Have you tried to restart the services and give it a try?

  What version of Essbase/Planning are you on?

  If the name of your server Essbase has more than 30 characters, please use NODENAME with the short server name.

• Create the link of database error

  Hi all
  
  I am trying to create a database link (developer both SQL and Sql * more) and I get the error ORA-00933: SQL not correctly completed command.
  
  Here is the statement:
  
  CREATE DATABASE LINK msrtp CONNECT TO msrtp_user IDENTIFIED BY 62ROLDS USING msrtp;
  
  Yes, the global database name is msrtp and I created links db without any problem.
  
  The problem, it's because the password begins with a number. I have no control on the password and can not change. I tried enclosing in single and double quotes, but it does not work. Is there one way around this other than to change the password?
  
  Oracle 10g
  
  Thank you.

  Try to put the password in quotation marks. I created a link using quotes around the password and I was able to choose to use it. With 11g and passwords case-sensitive using double quotes may be necessary at least for the mixed case passwords.

• database link is is created with incorrect password

  I have an A database is "sec_case_sensitive_logon" is set to true. Which means that I can open a session to the db using something as scott/tiger but not scott/TIGER.
  
  I have an another data base B which hosts all of my apex applications. Here I am trying to create a link of database data. Even if I am able to create the link very well using a sql statement or using APEX object browser "create"-> "database link", in the end when I test the connection it gives the name of user and password invalid.
  
  I think it's due to the APEX, still using the uppercase version of the password when creating the db connection IE. SCOTT/TIGER, which will not work.
  
  Can anyone provide guidance on how I can fix this?

  Use "" around your password in the definition of link

The TNSi under here are sample test, but it is working very well in here when connect you using the sql and sql navigator developer. (I think that nothing wrong with the tns) but is somehow the error message given TNS: could not resolve service name. So I don't really know what has gone wrong... PLEASE HELP ~ ~

  Hello
  If you create the link db on server 2 so you need a tnsnames.ora entry that points to the server 1.
  You should have an entry in the file tnsnames.ora on server - 2

  Server1 =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP) (HOST = 178.44.44.45)(PORT = 15210))
  )
  (CONNECT_DATA =
  (SID = server1)
  (SERVER = DEDICATED)
  )
  )

  then create the database on server 2 - link

  CREATE DATABASE LINK PUBLIC 'server1_schemaA '.
  CONNECT to schemaA
  IDENTIFIED BY password
  Using "Server1."

  Kind regards

• Db_domain and database links

  Hi all
  
  I have some problems and can not get rid of them, so if someone could help me...
  
  Well, I use 10.2.0.5 and try to do a replication of flow between 2 databases (this is not the topic here).
  I found my replication could not work due to the source database rename: there is no name domain appended to the end...
  

  SQL> select * from global_name;
  GLOBAL_NAME
  --------------------------------------------------------------------------------
  HARPTEST
  
  SQL> show parameter db_domain;
  NAME                                     VALUE
  -------------------------------- ------- ------------------------------
  db_domain                                .WORLD

  I don't know why, it's an old database and I can't change that.
  
  So now, as you can expect, while trying to make a database of my slave to this database link, I encounter errors:
  

  SQL> create database link harptest connect to streamsadmin identified by xxxxx using 'harptest';
  SQL> select * from dba_db_links;
  OWNER        DB_LINK                  USERNAME     HOST         CREATED
  ------------ ------------------------ ------------ ------------ ------------
  STREAMSADMIN HARPTEST.VOODOO          STREAMSADMIN harptest     30/03/12

  This is normal behavior, as I do not give db_name added to my dblink, it adds the local domain. But then, with my setting GLOBAL_NAMES set to TRUE, I run an error:
  

  SQL> select * from dual@harptest;
  
  ERROR at line 1:
  ORA-02085: database link HARPTEST.VOODOO connects to HARPTEST

  Of course, I could set the GLOBAL_NAMES of FAKE, but this isn't a solution because I'm having the same problem with my capture process.
  
  I try to disassemble the db_name of my line (put in a string of length zero), bounced back to the database, but the local db_domain is always attached to my name db_link. I also tried to rename the global_name of my line (quite wildly with an "global_name update" or "accessories$ '), but still the same.
  
  Do you know how I could connect to a database without domain name in its global_name?
  
  Thanks for any help!

  Hello;

  If you specify only the name of the database, then the field of the database to the Oracle connection string to create a full service name.

  This note of Oracle should give the options available:

  Create the link of database without end domain name [ID 462024.1]

• strange problem with the database link

  Hello world
  
  I have a strange problem with the link of database in Oracle 11 g Express Edition;
  There are two computers: computer-server and the client computer. Tnsnames.ora are the same on both computers IE.
  
  CT =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof) (PORT = 1521))
  )
  (CONNECT_DATA = (SERVICE_NAME = XE)
  )
  )
  
  I created the database link:
  
  Create database link zdalny
  Connect to < user_id > identified by < password >
  using "CT".
  
  Customer cannot connect with server when I do not use above the command. But when I change 'use' for using "krzysztof:1521" or by using "krzysztof" or "server IP:1521" - everything is ok.
  
  Why I ask. Because in all the materials that I read about Oracle command with the help of "CT" should work correct. But there is no. Do you know why?
  
  Thanks in advance and apologize me for my English.
  
  Rgds

  Here's the tnsnames of your server, but to connect to the oracle server db (any client or to another instance of db oracle), you must install oracle client.
  However, in your condition, you want to connect the DB1 Oracle OracleDB2 using a link db, I'm right? In this case you should always set the entry in the tnsnames.ora
  To verify that you can connect to Oracle DB2 from DB1 Oracle, you can use tnsping in the command line.
  In your case

  c:\tnsping CT

  )

  Check your tnsnames entry in the machine, you are trying to connect to. And check if the tnsping is successful.
  Sometimes the error message says not everything, which means that you need to troubleshoot yourself and learn from the experience.
  Always in the opposite case, refer to the documentation.

  See you soon.

• Database link question

  I read that it is possible to create a private database link and set up a public synonym to the private database link. But when I try it doesn't work. Is there another way to do this?
  
  My goal is to have the private database link and private synonyms exist in a single schema and have only certain users have access to. Is there another way to solve this problem without setting a private database synonyms and additional link in several patterns?
  
  Thank you
  Violet

  I understand that this error occurs because the database connection is private. This suggests that this scenario is not possible after all?
