I am trying to connect to a database using cx_Oracle in Python.
this is the way I'm doing it :
connection = cx_Oracle.connect("user", "pass", "service")
I am able to connect to the db using sql developer with the same credentials but when I try to connect from python it throws the error :
ORA-12154: TNS:could not resolve the connect identifier
specified.
I tried the same thing from another system and I am able to connect to the database using cx_Oracle. The contents of TNSNames.ora file are exactly the same in both systems.
I removed everything and installed again hoping to get rid of mistakes I might have done the first time but I am still facing the same error.
Please let me know if there is any way to fix this.
Thank You.
You can try with EZ connect instead, or you can use cx_Oracle.makedsn() to build up the connect string. If you provide the contents of your tnsnames.ora file I can provide a more detailed answer.
I realised what was going wrong.
The database uses a LDAP file. And in the SQLNET.ORA file, LDAP was not mentioned, that caused the error for me.
Just adding LDAP to NAMES.DIRECTORY_PATH in SQLNET.ORA solved this issue for me.

I'm trying to read data from Share Point online. I'm using KingwaySoft SharePoint Drivers on SSIS.
I'm getting below error even though with provided credentials
what could be the reason?
do I have to change the URL pattern?
Resolved
I have added /_vti_bin/listdata.svc/ at the end of the site URL.
like :
https://company0.sharepoint.com/sites/sfinfo/IT_team/_vti_bin/listdata.svc/
Thanks
The ideal service URL that you would need to provide should include the base site and subsite, if necessary, and no other details.
Give it a try and if the error persists, please reach out to our support team with the screenshot of the SharePoint connection manager configuration.

I have a cluster in mongoDB, and I want to connect to it in my node.js server. For that I need a url, but I can't find the correct form in the mongo site.
the format I'm looking for is:
"mongodb://remote_url:27017/databasetest"
so I am looking for the 'remote_url' part.
I am new to mongoDB so please help me.
I have already tried to click the 'connect' button and than choosing the 'connect to node.js app', but I get a different format.
(this is what I got):
"mongodb+srv://user:<'password'>#cluster0-afixn.mongodb.net/test?retryWrites=true"
My mistake. There is no way to reach this server through localhost or any IP since it is a cloud based cluster. Thanks for the help anyway.
