My published extracts are having issue to connect to the database in the same machine. Please find the screenshots in the attached doc and below is the scenario:
I connect to my database from desktop, and create reports.
Extract the data and publish it to server and the worksheets aswel.
when I refresh the extract from the tableau server, it gives me error as connection failed.
Oracle database, Tableau server and Tableau desktop, all are in the same machine.
tnsnames.ora file details are also mentioned in the attachment.
Kindly let me know the correct process to establish the connection
Thank you in advance.
