Hello all,
we'd like to submit to your attention what we're going to implement starting from \
OpenNMS 1.6.1 version. We have talked with Davide Hustace about this work and he \
suggest us to write to this developer list describing the work.
We need to work starting from version 1.6.1 because we have a short time delivery \
request, so we prefer to work on a recognized stable release. (or 1.6.2 last \
released)
I attach 2 class diagram to explain first steps we have thought so to realize a 3gpp \
event/alarm model.
Class_Diagram_3gpp_datamodel.jpg
----------------------------------------------------------------
describe an astract of actual OnmsEvent and OnmsAlarm class and some relations of \
these entities. Present the extention of the above with the declaration on all needed \
new attributes. For the 2 new classes is presented a box with some notes. A little \
description of the specific attribute, and a description for all derived attributes \
(meaning attributes already present into parent class, simply defined different \
accessor methods)
Class_Diagram_3gpp_datamodel-dao.jpg
--------------------------------------------------------------------
describe new classes needed to implements dao objects, with related changes into \
spring configuration. We're thinking to extends JdbcEventWriter and JdbcAlarmWriter \
so to save OnmsEvent3gpp and OnmsAlarm3gpp specific attributes, with a little \
modification of parent classes (Jdbc*Writer) so to be able to populate \
PreparedStatement with all OnmsEvent|OnmsAlarm attributes but being able to control \
if the PreparedStatement should be executed or just populated.
With David we have talked about a possible 3gppAlarmPersister to be used by Alarmd \
(alternatively to the actual AlarmPersisterImpl), but this approach is not in 1.6.1 \
so we are not able to follow it by now.
With the proposed approach all jsp and all other classes presents in OpenNMS will \
continue to work because OnmsEvent3gpp and OnmsAlarm3gpp are extentions classes.
Our idea is that one could start or with default event/alarm model, or with the 3gpp \
model. So we need to define a customization of database schema creation (referring to \
create.sql), for example an 'update_schema_3gpp.sql' to be invoked at the end of \
OpenNMS installation process and before start working with it.
What do you think about this? Do you see any contraindication ?
Thanks for any reply.
Andrea C.
