To go into the database you have to
setup oracle_client
then
sqlplus stt_param/password@d0onprd
Then you may apply SQL statements like
desc STC_MODULE;
select * from STC_MODULE;
(please give me a call for the password: extension 2736)

To fetch/put data into the database with python code say:

setup python_dcoracle
setup oracle_client
An example.py:
import dcoracle
import string

#open database connection
def opendb(passwd):
  constr='stt_param/%s@d0onprd' % (passwd)
  global dbc
  dbc=dcoracle.Connect(constr)
  global dbCursor
  dbCursor = dbc.cursor()


#close database connection
def closedb():
  global dbc
  dbc.close()


if len(sys.argv)>1:
    schema = sys.argv[1]
else:
    print "database keyword needeed!"
    exit
opendb(schema)

cmd='select SEQ_SERIAL_NO,SEQ_CHANNEL_ID, STC_CHANNEL_NO from STT_PARAM.STC_MODULE where
CRATE_ID='+str(crate)+' and STC_CARD_NO='+str(stc)
dbCursor.execute(cmd)
result=dbCursor.fetchall()
print "result=",result
for jrow in result: #loop over STC channels
  print "STC_CHANNEL_NO=",jrow[2]

closedb()
Have fun with it
