On save of the connection a strange MySQL related error is shown although I am creating an Oracle connection. This worked fine in the previous version of db connect.
Version 3.1.4, must be related to pi
I had the same problem in Splunk 22.214.171.124 and DB-Connect 3.2.0
I tried to made a new Oracle-DB-Connection and got mySQL error message. When I removed mySQL driver from DB-Connect I got the correct error message from Oracle jdbc driver.
As suggested by earlhelms it seems to be a bug in the mySQL jdbc driver, so I updated this driver from version 8.0.11 to 8.0.19 and this seems to solve the issue.
This appears to be related - https://bugs.mysql.com/bug.php?id=87600
Bug #87600 Connector throws 'Malformed database URL' on non mysql connection-urls
Incidentally, only one of may many Oracle databases is having this issue and it only started following an Oracle upgrade.
