With Ignition 8.1.11, I’m trying to configure a connection to an Oracle 12c database and I get the following error message: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor The IT administrator assures me that the values I’m using for the host, port, SID, username, and password are correct. I just downloaded and installed the JDBC jar file (ojdbc8.jar) from the Oracle website [JDBC and UCP Downloads page](https://www.oracle.com/database/technologies/appdev/jdbc-downloads-2.html) My connect URL is “jdbc:oracle:thin:@192.168.10.20:1521:MQ” Anybody else run into this issue? ---

Hi Larry, You might want to look at my reply in a separate [post](https://forum.inductiveautomation.com/t/oracle-database-connection-installation/43331/15). Ultimately what seems to be the issue is the connect URL likely should be: `jdbc:oracle:thin:@192.168.10.20:1521/MQ` Hope this helps, Garth
