Brian,

I would try to create a DBlink with full TNS definition - to see if it's 
working - e.g.

Create public database link "LIMS_TO_ERT" connect to "XXX"  identified by 
"XXXXX"  
using '(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL = TCP)(HOST=xxxxxxx)(PORT 
= 1521))) (CONNECT_DATA= (SID=dbsid) ) )'

I know, it doesn't answer your question - why tns address is not read from 
tnsnames.ora, however above can serve as a workaround.

Subject: db link


I'm creating a link:
 
  1  Create public database link "LIMS_TO_ERT" connect to "XXX"
  2  identified by "XXXXX"
  3  using 'PRODERT.ROSWELLPARK.ORG'
 
it tells me the link is created, yet when I try and access thru the link I get:
 
SQL> desc rpci.ert_lims_iface@lims_to_ert;
ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
 
I have the PRODERT.ROSWELLPARK.ORG in my tnsnames and I can connect with 
sqlplus to that db.  So what's wrong?  All we did was move the database to a 
new server. 
 
ciao,
Brian
