Hi Erman

We have clone procedure from our PRODUCTION database to PREPROD database.Database already opened without fail But this time we are facing an error from application layer.By the way this is not a standby database.We are cloning PROD disks to PREPROD.We are doing this for along time

Java.util.concurrent.ExecutionException: com.xxxxx.common.exception.DAOException: LocalDefaultDAO executePs ORA-16000: database open for read-only access</faultstring

Is your database really opened read/write?
Are you connecting to the correct database?

What is the output of following sql ?
->select open_mode from v$database;
