Home -> Community -> Mailing Lists -> Oracle-L -> RE: dblink problem ( ORA-02019 )
Hi
many thanks to all who replied to my query. I was able to solve the problem by changing the dblink create stmt. It seems the user had created the links as " CREATE PUBLIC DATABASE LINK abc.WORLD CONNECT TO username
IDENTIFIED BY pwd USING 'dbname.world' ; "
I recreated the dblinks as
" CREATE PUBLIC DATABASE LINK abc CONNECT TO username
IDENTIFIED BY pwd USING 'dbname.world' ; "
However , Kevin's reply has resulted in me finding another problem. When i did a "select * from global_name" on db A , i get "dbname.world" . but when i do the same on db B , i get only "dbname" ???
i crosschecked all init.ora , sqlnet & tnsnames params on both A & B ,and i
did
not find any differences. db_domain for both A & B is world, global_names is
FALSE.
db_name, instance_name & service_names are consistent across both A & B.
According to oradocs , global_name is a view for the init.ora param
GLOBAL_NAME.
Why is this diff coming and how do i resolve it.
thanks again

I had this problem in the past at a site where we were switching from .world to named domains. I can't remember exactly where I found it but I remember that the method Oracle used to determining the dblink domain was funky. On both databases, check "select * from global_name" and compare the result to "select * from dba_db_links". It seems to me that the domain extension on the global_name was used as the default extension when creating links. Caused me no end of heartburn -- nothing I couldn't work around, but more work arounds than I was happy with.
Hope my memory is sufficient since I don't have the problem at my current site.

hi
i have 3 databases(A,B,X) on 3 diff boxes. i have created 1 dblink each from A to X & from B to X. The syntax for dblink creation is exactly same for both dblinks.
I am able to query from dblink A-X as "select * from user.table_at_dblinkAX"
but when i try to query from dblink B-X as "select * from
user.table_at_dblinkBX"
i get the foll error
Error: ORA-02019: connection description for remote database not found
When i modify my query by suffixing '.world' as "select * from user.table_at_dblinkBX.world" , the query works fine.
I have compared the entries in init,sqlnet,tnsnmames,listener files on both
A & B
databases and they are absolutely similar .
i was thinking that the domain or globalnames parameters might be diff on A
& B ,
but they are absolutely same .
any suggestions are most welcome ...
thanks in advance
