<Connecting to the ADB Instance/Database Connectivity Issues>
I followed tutorials but it's not worked
https://docs.oracle.com/en/cloud/paas/autonomous-data-warehouse-cloud/user/connecting-nodejs.html#GUID-AB1E323A-65B9-47C4-840B-EC3453F3AD53
This is the tutorial link that i followed. Its official tutorial that provided by oracle.
this is the code that i used
import cx_Oracle
connection = cx_Oracle.connect('adb.ap-seoul-1.oraclecloud.com:1522/zjgfo1nip1q32o2_db_high.adwc.oraclecloud.com')
print(connection.version)
Error Codes: cx_Oracle.DatabaseError: ORA-12560: TNS:protocol adapter error
->
I installed oracle instant client in my computer and set wallet in it, also changed path variable.
Also I installed cx_oracle in anaconda3 that i use to interpret my python code in pycharm.
I changed tnsnames.ora file with adding http proxy and sqlnet.ora file with adding wallet location.
But it still returns error with tns protocol adapter error.
