RE: ora-12514

Hamid,

Are you using Unix? If you are, put your sqlnet.ora and tnsnames.ora in a generic location so that all homes can access them. For instance, on HP-UX we put them in /etc and on Solaris we put them in /var/opt/oracle. That way all the different versions are accessing the same files, no matter what their $ORACLE_HOME is set to. Unfortunately (fortunately for me, actually) :-) we don't have any NT servers with multiple ORACLE_HOMEs, so I don't know how you would do it on NT.

Hamid,

I got stung with this just yesterday. Look closely at the TNSNAMES file. Check this example:

WTWT_DBDOL0A1ADVWTW =
  (DESCRIPTION =
(ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = Dbdol0a1advwtw)(PORT = 1521))     )
(CONNECT_DATA = (SERVICE_NAME = wtwt)(SERVER = DEDICATED))
  )

WTWT_DBDOL0A1ADVWTW =
  (DESCRIPTION =
(ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = Dbdol0a1advwtw)(PORT = 1521))     )
(CONNECT_DATA = (SID = wtwt)(SERVER = DEDICATED))
  )

Look at the CONNECT_DATA line. Try changing the SERVICE_NAME to SID and try connecting again.

Hope this helps.

Hi list,
I asked this question this morning but no reply so I try again may be some chace. I have created a new instance under 8.1.7 and test it yesterday was fine, but this morning I try to shutdown the database and do some change on it after complete shutdown when I try to open the database got ERROR ORA-12514 TNS LISTENER could not Resolve SERVICE-NAME given in connect Descriptor. I have checked every thing non of tnsnames.ora or sqlnet.ora changed even I try connect from the server but no chance, we have two oracle home at the moment 8.16 & 8.1.7 on Sun Solaris. Any body have any idea what's going on??? Appreciate your help. Thanks.
