1025.0. "Maps disappear when notification is enabled" by HLDG00::GOES () Fri May 17 1991 08:36

To explain our problem we first give a situation:


With DECmcc V1.1.0  SSB

We have two domains: airco_fase2 and airco_fase3.
If we open domain airco_fase2 and enable an alarm rule everything works fine.
The alarm becomes true and the icon changes of color (notification is enabled).
If we now 'look up' the icon of domain airco_fase2 has also changed of color.
If we now try to open domain airco_fase3 it is opened .....
.... but the map is not displayed.

But if we do the above things with notification disabled the map ....
.... is displayed.

We have a few questions: it seems that the alarms are passed to higher levels
of domains (to 'parent domains'). How far will this be done (is an alarm passed
to all higher levels or only 2) ?

Another Question: is the disappearance af the domain a bug or is it a feature ?
Is it meant to be that other domains can't be opened in case of an alarm in 
another domain ?

re -.1

Let's try this:

1. Exit MCC

2. Restart MCC iconic map.

3. File->open airco_fase2.  Is the airco_fase2 map displayed?

4. File->open airco_fase3.  Is the airco_fase3 map displayed?

5. File->enable_notification

6. Repeat step 3.

7. Repeat step 4.


Let us know what happens.  Or send mail.
1025.3alarms passed all the way upTOOK::CALLANDERFri May 17 1991 09:0615
The alarming information (color changes) is passed all the way
back up the domain hierarchy. Where a "hierarchy" is defined as
a domain containing a dynamic domain. Each domain must be dynamic
(argument TYPE=) for it to be considered hierarchical.

As to why the map doesn't appear, did you also get a dialog box with
a message informing you of an error starting up notification? Some times
this can happen, and it tells you notification is be disabled for the
domain, but I have always seen it bring up the map.

Try, with notification enabled to open a new map window for the domain
you are trying to get to and see what it shows. Also from the FCL try
a show domain <name> member * all charactistics and see what it returns
for the contents of the domain.

	The capability to  pass  the  color  up the tree has no limits.
	If, for example you have:

	World
	   United States
	      Littleton
	         LKG
	            LKG-1
                       east-wing
           Europe
	      Valbonne
	   Japan
	   Australia
	     

	and an alarm goes off in domain east-wing, it will ripple up to
	world.  Note that with  V1.1  the  "highest",  not  last  alarm
	severity is displayed as defined by OSI standards.

	Could you more clearly show your  tree  so we could understand
	it better?   You say you have two domains, is one in another or
	are they totally  seperate  and  you have two windows opened at
	the same time?

    Is the problem that you're seeing when you try to navigate into
    airco_fase3 the same as the problem described in note 929?  If not,
    please supply more info.

    The problem that we're seeing is indeed the problem mentioned in note
    929 ! Thanks for pointing to that note.
    
    But we've done some tests and in one test the domain was opened with an
    empty map and not giving the appropriate message.
    
    First we'll supply you with our domain hierarchie (re .-4)
    
    Our domain hierarchie is:
    
           test_domain
              airco_fase2
     	      airco_fase3
    
    
    If we start DECmcc the default domain is test_domain
    
    If we perform the following sequence of operations:
    
    	1 Exit mcc
    	2 Restart mcc iconic map
    	3 File -> Open  airco_fase3
    	4 File -> Open  airco_fase2
    	5 File -> Enable Notification
    	6 File -> View Rule
    	7 Select an alarm by clicking the rule
    	8 Operations -> Enable
    	9 File -> View Member
       10 Wait until alarm comes true (icon changes color)
       11 File -> Open  airco_fase3
       12 File -> Open  test_domain
       13 Double click icon of airco_fase3
    
    everything works just fine except the last operation it causes:
    
    Notification structures may be corrupted. Please disable Notification.
    
    This was expected in note 929.*
    
    But if we perform the following sequence of operations:
    
    	1 Exit mcc
    	2 Restart mcc iconic map
    	3 Double click icon of airco_fase3
    	4 Navigation -> Look Up
    	5 Double click icon of airco_fase2
    	6 File -> View Rule
    	7 Select an alarm by clicking the rule
    	8 Operations -> Enable
    	9 File -> View -> Member
       10 File -> Enable -> Notification
       11 Wait until alarm comes true (icon changes color)
       12 Navigation -> Look Up
       13 Double Click icon of airco_fase3
    
    the domain airco_fase3 is opened, no map is displayed and no message is
    displayed.
    
    Maybe someone can do something with this information ?
    
    However, if we create a dummy domain in domain test_domain all our
    problems are solved (see also note 929.*).
