Hey @Shaukh Khan! I hope you must have the idea to do that by now. Can you please guide me how can I achieve the same. Looking forward to your response. Thank you.
I have oracle 12 c database I used your command pip install cx_oracle. after this command my oracle services from the service.msc has vanished. I cannot login to a connection in oracle. I am getting adaptor error. Can you please help?
At 4.08 where you didn't get error, I am getting cx_Oracle Database Error, cannot locate 64 bit client library, the specified module couldn't be found. I followed all previous steps. what did I do wrong?
after following the steps, I'm getting this error: >>> import cx_oracle Traceback (most recent call last): File "", line 1, in ImportError: No module named cx_oracle
Had the same error. Not sure if still up to date, since 3 months ago. lib_dir = r"C:\...path...\instantclient_19_9" try: cx_Oracle.init_oracle_client(lib_dir=lib_dir) except Exception as err: print("Error connecting: cx_Oracle.init_oracle_client()5") print(err); sys.exit(1); worked for me. I also added the instant client path to PATH via enviroment variables, but didnt work out for me. I wasted a whole day finding this solution for me... Also credits go to stackoverflow.com/questions/56119490/cx-oracle-error-dpi-1047-cannot-locate-a-64-bit-oracle-client-library, which helped me to figure it out.
Hi, thank you for this. I am struggling to connect to my Oracle DB on a different Windows system. While I can connect with Oracle MySQL Developer from my computer (and the connection is working), the set-up in the video does not work. I get either an ORA-12514: TNS: listener does not currently know of service requested in connect descriptor' (when I add the host name as path) or a connection timeout error. Any idea what might be a solution? Thanks!
Who has DPI-1047 error. Try reinstalling python with a different bit depth. For example, switching from 32bit to 64bit helped me. Only during installation, click the checkbox next to include to PATH. У кого ошибка DPI-1047. Попробуйте переустановить python другой разрядности. Мне например переход с 32bit на 64bit помог. Только при установке нажмите галочку возле include to PATH (вроде как-то так называется), это нужно, что бы в консоли у вас старая версия сменилась на новую (а то будете пытаться работать со старой версией)
I have an error when I import cx_Oracle. Do you know how I can deal with it? ModuleNotFoundError Traceback (most recent call last) in () ----> 1 import cx_Oracle ModuleNotFoundError: No module named 'cx_Oracle'
Hi, I'm getting "cx_Oracle.DatabaseError: ORA-12154: TNS: could not resolve the connect identifier specified" error. I cross check the path(C:\Users\mohit\instantclient\instantclient_18_5 etwork\admin) and tnsnames.ora file seems to be correct. I don't know where is my mistake, can anyone help? I'm using Windows 10 OS.
Hello Mohit. Can you double check your PATH? It should point to the Oracle Client directory, with a number of files e.g. DLL's in it. Also it could be because of a spelling error in tnsnames.ora. let me know if you require more help.
@@JeroenKloosterman Well, i was getting the same error. When i used the SERVICE_NAME value in place of "MYSERVICE" showing in the video, the error was no more...
I always get this error "DatabaseError: DPI-1050: Oracle Client library is at version 11.1 but version 11.2 or higher is needed" I updated Path variable with instat client path also ld_liberary_path
Thank you very much for the help. =] I'm also very interested in knowing what other languages you know. I have a guess but do not want to say and potentially be offensive or something lol May I know?
This step by step tutorial is really helpful while setting the Oracle DB connection. Really appreciate your effort.
after 2 freaking days of trying to work this thing out and going through half the internet your video is what helped me!!! THANK YOU!!!

Had the same error. Not sure if still up to date, since 3 months ago.
lib_dir = r"C:\...path...\instantclient_19_9"
try:
cx_Oracle.init_oracle_client(lib_dir=lib_dir)
except Exception as err:
print("Error connecting: cx_Oracle.init_oracle_client()5")

What happens in the background of cx_Oracle? How does it connect to the database?
how to downrange the versions ?!
How can I add the name/pw to the tnsnames.ora default service file? Also is there an example of usage?
