631.0. "AM and UCX udp socket issue " by TLSE01::HAGENMULLER () Thu Jan 17 1991 08:50

    
    Last week we developped an AM for managing UB ethernet hardware .
    When integating this AM in DECMCC we encoutered a problem that we
    didn't really solve .
    
    For talking to UB entities we've used UB proprietary protocol and UCX 
    udp sockets .
    When compiling linking our Am with UCX$IPC.OLB/LIB library , nothing
    wrong appeared .
    Enroll of AM was succesfull , but when we tried to use commands such as 
    
    	" show ub pcub all counters "
    
    we received an "access violation" when calling the routine "SOCKET" .
    Then we recompiled and relinked the AM with another library ,
    UCX$IPC_SHR.EXE/SHARE .
    Enrollment was still successfull , but with commands we got another
    error message : " opcode reserved for digital" or something like that .
    
    Finally , wu used UCX udp QIOs an rewrote our AM . All was OK .
    ( we tried to use MCC_QIO but didn't find the routine description in
    SRM V1.1 )
    
    This could be an issue when integrating some software developped on
    other UNIX platforms into the AM code .

	It sounds like simple programming errors.  I use the UCX sockets
	with no problem, and the code worked with NO modification on Ultrix.

	If you'd like we can follow this up off line, but I suggest you just
	go back to the socket documentation and work it out.

	Regards,
	Mike
631.2may be programming errorsTLSE01::HAGENMULLERFri Jan 18 1991 14:398
    
    may be simple programming errors .
    however , the code used for talking to UB entity was tested out of
    DECMCC and worked well . We used UCX V1.2 . May be my doc set was not
    complete . I you agree I can send you the code ( < 50 line s in C ) and
    follow this up off line , but I don't want to waste your time anyway .
                                   
    thanks , ch
