5662.0. "SERIOUS PROBLEM on notification of SNA-alarms" by STKHLM::BERGGREN (Nils Berggren EIS/Project dpmt, Sweden DTN 876-8287) Thu Oct 14 1993 19:44
**********************************************************************
This note is posted in both MCC and POLYCENTER_SNA_MANAGER
**********************************************************************
We're having a *SERIOUS* problem at a customer site I'm working
at helping them setting up the DECmcc environment.
The environment is: VAXstation 4000/90, VMS V5.5-2, 128 Mb, DECmcc 1.3.
The problem description is as follows:
They have two alarm rules enabled.
The first is an occurs-rule defined like:
(OCCURS (SNAnode SE_NS:.TELIA.C.SNA.SYS1 CLSTR XP3006
RECOVERY INITIATED))
SEVERITY=MAJOR
The second is:
(OCCURS (SNAnode SE_NS:.TELIA.C.SNA.SYS1 CLSTR XP3006
RECOVERY COMPLETE))
SEVERITY=CLEAR
There are also two NOTIFY REQUESTS enabled for the RECOVERY INITIATED
and COMPLETE events on that SNA-NODE.
In the notifications window we see the RECOVERY INITIATED event coming
and very soon after ( <2 secs) the RECOVERY COMPLETE event. The alarms
may come in various orders:
The events are ALWAYS notified in the right order, i.e. INITIATED
before COMPLETE.
1.
- The 'RECOVERY INITIATED'-event shows up first in notifications
window
- The initiated-alarm shows up AFTER the RECOVERY INITIATED-event
is displayed but BEFORE the 'RECOVERY COMPLETE'-event.
- The 'RECOVERY COMPLETE'-event is displayed AFTER The initiated-alarm
- The complete-alarm shows up AFTER after the 'RECOVERY COMPLETE'-event
This is the behaviour one would expect.
2.
- The 'RECOVERY INITIATED'-event shows up first in notifications
window
- The 'RECOVERY COMPLETE'-event is displayed AFTER 'RECOVERY
INITIATED'-event
- The complete-alarm shows up AFTER after the 'RECOVERY
COMPLETE'-event **BUT** before the initiated-alarm
- the initiated-alarm shows up last, LEAVING THE SEVERITY OF THE
OBJECT TO MAJOR when it should be CLEAR.
3.
- The 'RECOVERY INITIATED'-event shows up first in notifications
window
- The complete-alarm shows up after after the 'RECOVERY INITIATED'-
event (** AND THIS IS VERY SERIOUS **) before the 'RECOVERY
COMPLETE'-event which is the event triggering the alarm.....
- the 'RECOVERY COMPLETE'-event shows up AFTER the complete-alarm
- initiated-alarm shows up last, LEAVING THE SEVERITY OF THE
OBJECT TO MAJOR when it should be CLEAR.
After looking in the notification-log especially the ALARM-entries, I
see that the date-and-time of the event triggering the alarm matches
the way the alarms are displayed, i.e. if the time-stamp of recovery
complet is before recovery initiated I see the alarms in wrong order.
Well, this is not acceptable. We can tell for sure that the events are
sent, from NetView, in the right order.
Why do we get the wrong order when arriving to DECmcc?
Does the SNA_SERVER process have problem posting the incoming events
in the right order, or is it the EVENT_MANAGER causing the problem?
I know there's not to many SNA-AM installed, but for those of you who
have customers running it, have you seen anything like this?
I would very much like to test this on another entity class, but I
don't know for which class I can generate two different events in less
than two seconds. Anybody any idea, please let me know....
The customer thinks that this is a show-stopper and are not going to
use the SNA-AM (and maybe ont DECmcc at all) if we can't provide them
with a solution.
One of the main reasons we got the business them was the SNA-AM.......
Please, anybody any idea what to do?

| Forgot in the previous note:
Can logging be enabled for the SNA-am and SNA_SERVER process
so that we can see the exact time-stamp when the events are received?
What logical names has to be defined?
