For example, if the type of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached.

A question about CREATE PUBLIC DATABASE LINK and ORA-12154 error Discussion in 'Server Administration and Options' started by dariyoosh, Nov 17, 2009. dariyoosh Forum Advisor Messages: 118 Likes Received: 19 Trophy Points: 260 Dear all, I have a problem about public database creation and I would appreciate if you could kindly give me a hand. I have the following connection parameters in my tnsnames.ora file: Code (Text): ... 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*Plus shell: Code (Text): $ sqlplus username/password@DGPAPROD.WORLD This works pretty well and the connection is established without any problem. Now, what I would like to do is to create a public database link to this remote database in order to avoid the user/connection switching for viewing the content of this database. I proceeded according to the syntax indicated in the Oracle online documentation: http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_5005.htm#SQLRF01205 Therefore I run the following in order to create a public database link Code (Text): 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 resolves the remote host and whenever I run the following query Code (Text): 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 dariyoosh, Nov 17, 2009 #1 Kirti Forum Advisor Messages: 46 Likes Received: 12 Trophy Points: 130 Hi In which database are you creating this Database Link? On the database where you are creating this DB link, is DGPAPROD.WORLD present in the tnsnames.ora? Alternately you can bypass tnsnames and create the DB link directly using the hostname and port and SID, something like this: Code (SQL): CREATE DATABASE link "TEST" CONNECT TO APPS IDENTIFIED BY "apps" USING '10.31.4.121:1524/DEVR12' Kirti, Nov 18, 2009 #2 dariyoosh Forum Advisor Messages: 118 Likes Received: 19 Trophy Points: 260 Kirti said: ↑ Hi In which database are you creating this Database Link?
