1915.0. "RECORD attr. and ACCVIO" by DGOSW0::GUESDON () Wed Dec 11 1991 05:26

    We've got some problems with the COGEMA specific AM (written to manage
    COGEMA's X25 switches), using the iconic map PM with "RECORD" attributes:
    
    When we do a SHOW command on any attribute of type RECORD, we have an
    "ACCESS VIOLATION" message under the Iconic Map PM, while everything
    works fine if we do the equivalent command under the FCL PM.
    
    The MSL looks like this for one of the records defined:
    
    TYPE ligne-insertion = 9903 RECORD
    		LG_ADDR = 1 : Unsigned8 ;
    		ADDR_APPELANTE = 2 : DTEAddress ;
    	END ;
    
    	.../...
    
    ATTRIBUTE Ligne 01 initiale = 7501 : Ligne-insertion
    	ACCESS = SETTABLE,
    	DISPLAY = TRUE,
    	CATEGORIES = (CONFIGURATION),
    	SYMBOL = UR_INS__LIG01_INI
    END ATTRIBUTE ;
    
    ATTRIBUTE Ligne 02 initiale = 7502 : Ligne-insertion
    	ACCESS = SETTABLE,
    	DISPLAY = TRUE,
    	CATEGORIES = (CONFIGURATION),
    	SYMBOL = UR_INS__LIG02_INI
    END ATTRIBUTE ;
    
    .../...
    
    ATTRIBUTE nb lignes table insertion = 7511 : Unsigned8
    	ACCESS = NONSETTABLE,
    	DISPLAY = FALSE,
    	CATEGORIES = (CONFIGURATION),
    	SYMBOL = UR_INS__NB_LIG
    END ATTRIBUTE ;
    
    The ILV returned from our AM:
    
    [  1 ] (
    	[  1 ] (
    	    [  7501 ] (
    		[  1 ]		0d
    		[  3 ]		00
    		[  4 ] (
    		    [  1 ]		07
    		    [  2 ]		39 31 34 30 33 36 30  -- 9140360
    		    )
    		)
    	    [  7502 ] (
    		[  1 ]		0d
    		[  3 ]		00
    		[  4 ] (
    		    [  1 ]		02
    		    [  2 ]		39 30  -- 30
    		    )
    		)
    
     ....
    
    When we try to click on the SHOW option, the first record is displayed,
    and then MCC main program gives us the ACCVIO message.
    
    Have someone any idea on the reason of this problem ?
    
    Thank You

A few questions:

	- what version of MCC are you using?
	- by show command, do you mean show current value (from the Management
	  Window Operation Menu) or Show <entity> <instance>?
	- "When we try to click on the SHOW option, the first record is 
	   displayed, and then MCC main program gives us the ACCVIO message."
	   I am not sure what you mean by the above.

    1. We're using DECmcc 1.1
    
    2. We use the Operations Window menu and click on "SHOW" and then on the
    attribute partition containing the record attribute.
    
    3. When we do the operations stated in point 2., a window is opened
    displaying only the first record of the attribute. In the window
    containing the $MANAGE/ENTER/INTER=DECW command, we have the ACCVIO
    message.
    
    4. When we do a SHOW <entity> <instance> ALL <partition> using the FCL
    PM, everything works fine.

Michel,

Thanks for the information.

A lot of constructor datatype problems have been fixed since V1.1. Looking at
your ILV dump, I do not see any problems there, so my expectation is that
with a later version of MCC, the acc-vio should go away.  

Hope that helps.
