Hi, The ORA-01013 may occur when the previous query execution has failed or if the connection is not valid during execution. I would verify if the ‘Ping Query’ is provided to check the connection is valid before query execution. You can verify this by going to ‘Administration > Server Configuration > Cache’ and under ‘Connection’ tab, you can give the Ping Query under ‘Connection Pool Properties’. I advise you to provide a valid ping query supported by the datasource. Hope this helps!
