RMAN-03019
        asynchronous RPCs are NOT working
        
        
        Cause
        The RPCTEST command has determined that RPCs are not executing asynchronously.  Instead, they are blocking.  This is caused by using a SQL*NET driver that does not support non-blocking UPI.
        Action
        Try using a different SQL*NET driver.
