Additional considerations
OAD can only function with security enabled for Java Message Service (JMS) Notifications. The probe cannot allow security to be enabled for JMS Notifications and disabled for the Web Services interface at the same time. Therefore, both JMS Notifications and the Web Services interface must have security enabled.
When OAD is installed
in a cluster, the notification identifiers for OAD generated alarms
assigned by one OAD server do not follow sequentially those assigned
by another OAD server. This affects alarms such as heartbeat
or eventLossOccured
,
. Since Netcool/OMNIbus uses the notification identifier to correlate
some alarms in the EventList
, if the activity has
switched from one OAD server to another in the cluster, the EventList
can
potentially correlate unrelated alarms since their notification identifiers
can match. This is not applicable to NE or AMS alarms: their notification
identifier is constructed in the format domain_name:number
,
so it is unique; the same notification identifier is used for the
same alarm across all the cluster nodes.
