ORA-21560
        argument at position string is null, invalid, or out of range
        
        
        Cause
        The value of the argument at the specified position was null, invalid, or out of range. For example, when a LOB or BFILE positional or size argument has a value outside the range 1 through (4GB - 1), or when an invalid open mode is used to open a file. This error is reported when an API is invoked with invalid arguments.
        Action
        Correct the API call in your program to not pass a null, invalid or out of range argument value.
        
     
    
    
        ORA-21560
        argument string is null, invalid, or out of range
        
        
        Cause
        The argument is expecting a non-null, valid value but the argument value passed in is null, invalid, or out of range. Examples include when the LOB/FILE positional or size argument has a value outside the range 1 through (4GB - 1), or when an invalid open mode is used to open a file, etc.
        Action
        Check your program and correct the caller of the routine to not pass a null, invalid or out-of-range argument value.
