Vikram,
I worked at a company that used DSO for exactly what you are discussing,
used to archive things off of production to a reporting server, and make
that reporting server 'real time'....it was a good solution for us at the
time, but looking back, I wouldn't do it again.  The DSO engine is NOT
intended for data replication, as others have mentioned...it's really
intended for follow the sun operations, as such its throughput is relatively
slow for the task you are looking to do.  We are embarking on a similar
initiative at my current company and we are opting to go with db
replication.  Replication comes with its own set of baggage, but I believe
that baggage is manageable.

Subject: Using DSO to sync two AR Servers

Hi listers,

Greetings,

I have a new challenge thrown at me.. now the performance of the system is
good enough (if you remember my tiring question about ARS performance and
huge queries) now I have been asked to find a way to keep 2 application
servers in sync at real time. And what I could think of is to introduce DSO
to into the picture. So here it goes:

1) Is it best to use DSO to keep 2 Application servers in sync all real
time.
2) Both the application servers are replicas of each other but
geographically located.
3) The ARS application is completely customized with 350+ forms to be
managed in sync.
4) Also DSO is to be used to archive data from one of the servers into the
other which will be used as just an read only reporting server.
5) Both the servers are ARS 5.0.1 :)

So I would really appreciate if you can help me through this as well as you
did in my previous endavour.

My questions :

1) Is it reliabe to use DSO in this big context?
2) What all factors do I have to keep my eyes on while doing this?
3) What is the performance hit that if at all one can expect?
4) Any specific setting that can be implemented to keep the performance up?

I guess this is a nice learing experience for someone like me and would like
any help possible from you guys.


Thanks in advance

Regards,
Vikram.
