Hello,
We're using a specific alarm notification procedure in our alarm rules because
we have to display specific entity information in addition to the DECmcc alarm
information. The type of the alarm rules is event detection (OCCURS) format.
- Sometimes, the alarms rules fire (shown by the icon changing colour),
but we can see both of them not working:
o We do not see any alarm broadcast !
o It appears that alarms are not being broadcasted in the same order as it's
done by the 'Event Put' routine encoding.
- And some alarms seem to get lost completely when there are too many to fire
off. Is there a limited number of alarms ?
Are they known problems in V1.1 ?
Best Regards,
Thierry.

I don't know of any explicit problems with ALARMS notification in the V1.1
product. But here are some things to consider.
When ALARM notification is done, a job is submitted to your batch
queue. If you have a large number of rules firing, it is quite likely
that you will see a delay between visual notification (clour change) and
the ALARM notification. I do not know what happens when your queue is
full and another job is submitted -- could it get lost?

Also note that MCC is multi threaded. This means that multiple rules
mean multiple processing "threads". These threads are scheduled on a
first "ready" first activated basis. This doesn't necessarily mean that
the first on activated is for the first event put...
