Thank you kubig, It is working now with your suggession, and others idea.
Here’s my jdbc url
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL = TCP)(HOST = databaseserverhost)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME= databasename)))
We have also to configuring hibernate.remote.database option with the value blank. We must use CME to do this because with Administraor it is a mandatory option.
Thank you all for your help. It’s Ok now
