cx_Oracle連接問題

我已經知道這個oracle數據庫，嘗試了幾個命令的組合，但仍然無法連接。下面是我最近嘗試連接的。cx_Oracle連接問題

ip = "173.37.65.217" #datamart 
port = '1810' 
SID = 'fntr3prd.cisco.com' #'ARCHIVE_HC6_ARCH'#"fntr3prd" 
username = 'xx' # I don’t have permission to share 
password = 'xx' # I don’t have permission to share 
dsn_tns = cx_Oracle.makedsn(ip, port, SID) 
con = cx_Oracle.connect(username,password,dsn_tns) 
cur = con.cursor() 

cur.execute("select * from ARCHIVE_HC6_ARCH」)

的例外，我得到...

Traceback (most recent call last): File "/Users/tlombard/Desktop/FY16Metrics/ppmArchive.py", line 12, in con = cx_Oracle.connect(username, password, dsn_tns) DatabaseError: ORA-12505: TNS:listener does not currently know of SID given in connect descriptor

注：如你可以看到下面，我能夠連接到這個數據庫用sqlplus ...

什麼任何想法我應該嘗試下一個？

SID通常不是服務器的dns名稱，你有沒有其他方法可以訪問數據庫Toad？ – John

這可能是因爲您使用的服務名稱，而不是一個SID的

嘗試

dsn_tns = cx_Oracle.makedsn(ip, port, service_name=SID)

謝謝#Diver！你讓我朝着正確的方向前進......解決我使用的問題：dsn_tns = cx_Oracle.makedsn（ip，port，service_name ='fntr3prd.cisco.com'） –

假設你有一些其他類型的訪問數據庫的嘗試

SELECT sys_context('USERENV', 'SID') FROM DUAL;

，並用它來代替

SID = 'fntr3prd.cisco.com'

您是否已經安裝了oracle客戶端併爲其配置了LDAP配置？
