Working with GLOBAL_NAMES=TRUE can be tricky until you fully understand
everything. Maybe even after that. I haven't used them long enough to tell.
One thing I notice from the information you have provided, it appears that
the GLOBAL_NAME of one of your databases is "fnd_remote". It does not appear
that there is a domain appended to the GLOBAL_NAME. If this is true, that
might be the root of your problems. How are you setting the GLOBAL_NAME of
your databases? Are you using ALTER DATABASE? That will automatically append
the domain. If you just do an update to GLOBAL_NAME, then the domain will
not be appended, but that is not correct and might cause problems with your
links.
If you don't have a strong reason for understanding GLOBAL_NAMES, Igor's
solution has some merit.

Subject: Urgent help: strange DB_LINK problem...
List...
Please, help me to solve this thread, I've been trying
for a whole day and cannot find the problem...
also, I've been searching at Metalink with no luck.
this is the scenario:
1.- Local BD: Oracle 8.1.7, SID = fnd on Solaris 5.8
1.1 TNSNAMES.ORA has a FND_REMOTE alias for Remote BD
2.- Remote BD: Oracle 8.1.7, SID = fnd on Solaris 5.8
Note that both are the same SID, DB and OS version.
They are at distinct locations.
On local BD, tnsnames.ora is configured correctly,
I've checked in this way:
1.- $ tnsping fnd_remote
Attempting to contact
(ADDRESS=(PROTOCOL=TCP)(Host=xx.xx.xx.xx)(PORT=1522))
OK (10 msec)
2.-
SQL>
connect sys/my_incredible_secret_password@fnd_remote
Connected.
The problem starts when I create a PUBLIC db_link.
SQL> create public database link fnd_remote
2 using 'fnd_remote';
Database link created.
I'm configuring Symmetric Replication, so, I need a
PUBLIC database link like above.
And, now... and type:
SQL> select * from global_name@fnd_remote;
select * from global_name@fnd_remote
*
ERROR at line 1:
ORA-12154: TNS:could not resolve service name
Facts:
global_names = true on both databases
Connectivity is OK in both ways.
Any ideas?
Thanks in advance!
JL
