1438.0. "Iconic Map and Alarms problem" by OFFHK::ALLAIN () Tue Sep 03 1991 18:25

Hi, I've a problem with the Iconic Map and Alarms:

1:
After receiving an alarm, I use Display Selected Alarm operation to see the 
alarm that has been "triggered". I got a window showing all the information.

2:
I DON'T CLICK on OK (that means I keep this window open), and when a 
second alarm comes, I "goto 1" (I display selected alarms), and I see 3 alarms 
in the list: The first one, the first one again, and the second one!!

So, it sounds like the Iconic Map is disturbed when I don't remove the window 
showing the previous alarm before displaying the nex one.

When I simultaneously run the notify commnand from the FCL, I see only 2 alarm
reports. (I don't get the first one duplicated). This is what makes me believe
that the Iconic Map PM may be responsible for this duplication.

Any idea about this? If this is a problem of my code (get/put event), what could
be the reason??



Thanks for any help.

Francois.

1438.1	Yes! I've seen that too.	TOOK::GUERTIN	Don't fight fire with flames	`Wed Sep 04 1991 00:32`	11
	I've seen this before when I have had the same notification enabled twice. Once from the iconic map, and again from FCL. Apparently, notifications are system-wide (? - I seem to recall they post events to the Event Manager). This seems to result in the exact same notification event being picked up twice. It happened to me last Friday, so this just an educated guess. Could you be doing notifications from FCL or another Iconic Map? I found the behavior confusing, since it looked like two notifications at FCL. Then when I looked closely at the text, I noticed that they were both identical. -Matt.

	Hi Matt, I'm not completly sure, but I believe that it did happen to me with just 1 notification running. I'll check it again just to make sure, and I'll let you know. (It's nice to know that someone already had the same problem, I feel better...) Francois.
1438.3	More info.	OFFHK::ALLAIN		`Wed Sep 04 1991 14:35`	8
	More info: If I don't clik on OK in the Current Alarms window before receiving the next one, and displaying it, then I can't get rid of that window anymore!! That sounds more like a IconicMap problem than like a Alarms problem, doesn't it? Francois

	Francois, Yes, there was a bug in the Iconic Map regarding the Display Alarms menu items. There is only supposed to be one DisplayAlarms window up onscreen at any time. Therefore, we dim out the the menu items when the DisplayAlarms window is up. Unfortunately, there was one spot in the code that we missed dimming the menu items. One of the symptoms that I've seen is that you can't get rid of the window anymore. The duplicate alarm info MAY be a symptom too. I'm not sure, but it seems likely, looking at the way the code is written. I wish I can double-check the duplicate alarm info for you, but I'm not working out of the Littleton office anymore. And my workstation is not set up yet. Christine
1438.5	I recognize those symptoms too!..	KERNEL::MACLEAN	I CAN and I WILL...But Not today!	`Sat Sep 07 1991 14:18`	16
	Hi!, I have a customer who is also currently seeing the behaviour with Notification arriving twice and also the problem with one Display alarms Window remaining when you have had 2 active at one time. He is sure that the Notification is only enabled from the Map and not from both the Map & FCL.! Is it likely that a fix will be produced to workaround the Display Alarms window problem??? Regards, Sandie..........

	by a fix you mean a patch?

	yes.
1438.8	Multiple notifications from FCL	VCSESU::WADE		`Mon Sep 09 1991 15:29`	60
	I wonder if this FCL problem is related. From the documentation, BMS pg. 2-16, "A notification directive runs continuously, ... until ... you exit the current DECmcc session." I receive multiple notifications if I start a notification directive in another session after I've left a prior session without terminating the notification directive. * SESSION 1 * $ man/ent notify domain work_stations entity list = (node4 comms remote node comms),event = (counters zeroed) !%MCC-S-NOTIFSTART, Notify request 1 started ! zero node4 comms ! !Node4 63.367 !AT 9-SEP-1991 11:28:13 ! !Zeroing of Counters completed successfully. !%%%%%%%%%%%%%% Event, 9-SEP-1991 11:28:14 %%%%%%%%%%%%%% !Domain: COMMS2_NS:.work_stations Severity: N/A !Entity: Node4 63.367 Remote Node 63.367 !Remote Node counters ! exit * SESSION 2 * $ man/ent notify domain work_stations entity list = (node4 comms remote node comms),event = (counters zeroed) !%MCC-S-NOTIFSTART, Notify request 1 started ! zero node4 comms ! !Node4 63.367 !AT 9-SEP-1991 11:30:47 ! !Zeroing of Counters completed successfully. !%%%%%%%%%%%%%% Event, 9-SEP-1991 11:30:47 %%%%%%%%%%%%%% !Domain: COMMS2_NS:.work_stations Severity: N/A !Entity: Node4 63.367 Remote Node 63.367 !Remote Node counters !%%%%%%%%%%%%%% Event, 9-SEP-1991 11:30:47 %%%%%%%%%%%%%% !Domain: COMMS2_NS:.work_stations Severity: N/A !Entity: Node4 63.367 Remote Node 63.367 !Remote Node counters ! exit ! If I kill the MCC_DNA4_EVL process and restart it, everything is fine.

	I believe that this has been qared against the dna4 evl already. I will check.
