ORA-64760
        Database string has had tasks in ordering wait state for over string days.
        
        
        Cause
        The specified database had an INDEX_BACKUP task that could not be run because the task did not tile against the delta store. An incremental backup piece could not tile into the delta store because the necessary control file information was missing or because the backup that it depended upon was not found in the delta store.
        Action
        Resolve the warnings for the database. A new full backup for the database should also clear this condition.

        ORA-64760
        Database string has had tasks in ordering wait state for over string days.
        
        
        Cause
        The specified database had an INDEX_BACKUP task that could not be run because the task did not tile against the delta store. An incremental backup piece will not tile into the delta store when the full backup that it was built upon is not found in the delta store.
        Action
        Provide the missing incremental backups for the database.  If no other incremental backups can be found, provide a new full backup for the database.
