After deploying cf11 update 12, in cf administration > Datasource when testing connexion, I get an error :
SQLException while attempting to connect: java.sql.SQLNonTransientConnectionException: [Macromedia][Oracle JDBC Driver]No more data available to read..
Then I have replaced macromedia-drivers.jar in lib sub-directory with the one from CF11-update 6 and restarted coldfusion : problem has gone.
I am running CF on a windows 2012 64 bit system and oracle database is also windows 2012 64bit.
I had same issue with updates 8,9,10 and 11.
Why is adobe not fixing such bug ? Should I use other dirver to access oracle database ?
