In cx_oracle mailing list, they suggested me, this:
... write your own equivalent of makedsn, which really ought not be too hard.
You'd want to emit something like this:
I solved the problem using this monkeypatch to makedsn as suggested me
by Christoph Zwerschke.
makedsn = cx_Oracle.makedsn
cx_Oracle.makedsn = lambda *args, **kw: makedsn(*args,
**kw).replace('SID','SERVICE_NAME')
Thaks any way to everyone.

The latest version of cx_Oracle 5.1 is changed:
5) Added additional parameter service_name to makedsn() which can be
used to
use the service_name rather than the SID in the DSN string that is
generated.
makedsn(host =
I also tried two different connection mode.
The first one works but the second one using makedsn doesn't.
def init_db_conn(parms): #this work
import cx_Oracle
dburi=%(user)s/%(password)s@%(host)s:%(port)s/%(sid)s % parms
return cx_Oracle.connect(dburi)
def init_db_conn(parms): #this
so makedsn() will give you:
cx_Oracle.makedsn(oracapsul.net, 1521, SHELL)
'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=oracapsul.net)(PORT=1521)))(CONNECT_DATA=(SID=SHELL)))'
and that should match in your tnsnames.ora file
($ORACLE_HOME/network/admin/tnsnames.ora). would have
Ok, I changed the file $ORACLE_HOME/network/admin/tnsnames.ora but it
still doesn't work.:

yeah I dunno, the problem is at the cx_Oracle / OCI level at this point,
since you can illustrate cx_Oracle/makedsn() not working. You might need to
ask on their list at this point (only give them the init_db_conn() scripts,
don't give them any SQLalchemy stuff):
