We have a SQL Server database that needs to link to an Oracle database. I have been able to successfully setup this "linked server" entry in SQL Server, but only when I am using a local TNSNAMES.ORA. We typically have all of our Win2000 machines point to a central TNSNAMES.ORA file that is on a file server using ifile (in the local tnsnames). For example:
ifile="//cluster01\apps\oracle\sqlnet\tnsmaster.ora" < this works for SQL*Plus only> Using the above "ifile" entry in the local TNSNAMES file, I am able to connect to databases from this box using SQL*Plus. However, my SQL Server "linked server" reports a "ORA-12154: TNS:could not resolve service name". If I change my ifile entry to use a local tnsnames file, I no longer get this error from SQL Server. For example: ifile=c:\oracle\ora920\network\admin\tnsmaster.ora < this works for SQL*Plus and SQL Server> SQL Plus works for both scenarios. SQL Server works only for the second scenario. What has me stumped is that SQL*Plus works, but SQL Server does not. I think it might be some type of network rights issue, but I have not confirmed it. Does anybody use SQL Server to link to an Oracle database, using a TNSNAMES file that is remote?
